Trapped In A Dating Sim / Tropes G To O

Tropes for Trapped in a Dating Sim: The World of Otome Games is Tough for Mobs
Tropes Zero to F | Tropes G to O | Tropes P to Z

G-H

• The Gambling Addict:
  • Marie's (reincarnated world) parents keep racking up gambling debts, leading to them being Impoverished Patricians, unable to properly feed and clothe her, and pushing their debts onto her.
  • In Marie's past life, one of her boyfriends also had huge gambling debts and saddled them onto her. Two lifetimes of being Trapped by Gambling Debts has led Marie to hate gambling.
• Gender Bender: The A.I. Cleare turning Aaron into a girl, for her own amusement.
• The Generation Gap: It's discussed that the third volume has created one of these. Any woman who graduated from the Royal Academy prior to the banning of Exclusive Servants is considered extremely undesirable, in part being Defiled Forever and stereotyped as a Royal Brat. Due to this, Leon's younger sister Finley gets a lot of suitors, while Jenna who's part of that generation, scares men out of the room when revealing she had graduated the Academy. Clarice is also undesirable thanks to this shift, despite still being popular with lower nobles.
• Genocide Backfire: The story of the second otome game can be summed up as this — The heroine is a Fallen Princess who is the only survivor of a Ruling Family Massacre and secretly lives as a commoner girl. The final villain is the head of the noble house responsible for the death of the heroine's family and has since placed his family as the reigning house of the Alzer Republic. The main villainess is the villain's only daughter, who goes out of her way to bully the heroine. The heroine, with her chosen love interest, defeats the final villain who seemingly causes the country's sacred tree to go on rampage.
  • In reality, events are more complex than what the game entailed. For one, Albergue Sara Rault had legitimate grievances against the Lespinasse House. Not only that, he saw Noelle and Lelia as innocent of the their family, and so actually spared them.
• Genre Mashup: It's an Otome Isekai (popularized by My Next Life as a Villainess: All Routes Lead to Doom!). It's also, a world of Sword and Sorcery with adventurers and Dungeon Crawling. It's also, a sci-fi world with Mini-Mecha, fleet battles fought by many massive airships, and Artificial Intelligence.
• Girl on Girl Is Hot: Leon and his friends Daniel and Raymond think this about the closeness between Livia and Angie. Leon gets very interested when Luxion uses his Power Perversion Potential to show him a simulation of the two going further.
• Girl Posse: In addition to flaunting her wealth with several Exclusive Servants, the daughter of Earl Offrey has one of these to help her bully Leon and Olivia, one of whom is Carla. Interestingly, said daughter acknowledges that these kind of people are Fair Weather Friends, and threatens Carla's family, to make sure Carla does her bidding.
• Glory Seeker: King Roland, who's been itching for the chance to give an epic performance defending the kingdom, as well as donning The Masked Knight Secret Identity. He never gets the chance to do either, due to Leon and Julius, respectively, stealing his thunder. This starts Roland's grudge against Leon.
• Glowing Eyes of Doom: Angelica and Luxion, who both have red eyes, sometimes have them described as glowing to emphasize their anger.
• Gold Digger: Very common in the Academy, and why Leon and his fellow poor nobles are ignored. It's revealed in the third volume, that tea parties for popular high ranking male nobles in the academy mostly consist of asking about the man's income and such.
  • Marie was born into an Impoverished Patrician household, who gamble away and otherwise squander any money they get their hands on, bleeding their territory dry, and pushing their debts onto Marie. Independence from her rotten family is one of the main factors motivating Marie's seduction of the Five Dateable Cast.
  • Leon's older sister Jenna sets her eyes on a Viscount's heir, because they just discovered riches in their land. Jenna tries to persuade Leon into making threats to achieve this.
  • In the Alzer Republic, Lelia is only in a relationship with Extreme Doormat Emile for the security and wealth that he can provide her, treating him quite badly. Both before and during the story, Lelia shows a recurring pattern of only seeing men for their ability to benefit her.
  • Leon's little sister Finley, who like her older sister is The Cynic, aims for this upon entering the Royal Academy, but her older siblings try to warn her to lower her expectations.
• Go Mad from the Isolation: Downplayed. This is the cause of the A.I.s found in the story having such extreme personalities, laying dormant a great many years after the demise of the civilization that that built them, being forced by a Restraining Bolt to stay put. Leon notes before finding Luxion, that it's a sad fate.
• Good Is Not Nice: With Leon, it's positively jerkass. It's pretty much his standard procedure with opponents to Break Them by Talking, and if really mad, Kick Them While They Are Down.
• Go Out with a Smile: When Emile, after becoming the Final Boss of the second game, goes to a Journey In The Center Of The Mind with Lelia, he finally understands and forgives her, dying like this after making her priestess.
• Gratuitous English: At the start of his bike race, Leon shouts "Goddamn!" in English, to Luxion's bewilderment. In the English translation instead, Leon yells "Scheisse!"
• Gratuitous German: Luxion is fond of giving his creations German names, such as Arroganz (arrogance), Partner (partner), Schwert (sword) and Einhorn (unicorn). He specially named Leon's mech Arroganz as a Stealth Insult. He also refers to the royal family's airship as "the Weiss" (white)
• Greater-Scope Villain: The New Mankind civilization that Luxion bears a grudge against the descendants of, seems to be this. Monsters, and other Organic Technology that power up the villains, all came from them.
• Green Thumb: Kyle's mother Yumeria, has a unique magical skill among Elves: To manipulate and grow plants. She is shunned for the ability, due to it making her look horrific to the Elves' innate Aura Vision.
  • Alzer Republic nobles each have a crest from their Sacred Tree. They can be used in two ways: To spring up roots to entangle and disable the magic of an opponent, and to enforce Sacred Vows. A vow's conditions aren't required to be fair, and breaking one results in either one's neck being snapped by vines, or if an Alzer Noble, being depowered.
• Had to Be Sharp: It's stated that due to having to brave the dungeons to impress and buy gifts for girls, noblemen of Holfort Kingdom are generally much better fighters than those from the complacent Alzer Republic.
• Hands-On Approach: Angelica gets distracted with this while teaching Olivia horseback riding.
• Has a Type: This is something of a Running Gag with Leon's preference for big breasts.* Reason goes out the window when Leon realizes his nation's queen fits his perfectly, shocking everyone and getting him Punched Across the Room by Julius.
  • Leon goes overboard describing this at a marriage shrine, again in front of other Love Interests, and a Shrine Maiden, earning an ear pull from Angie.
  • Hertrude thinks she can win Leon over to her side as a Femme Fatale, but doesn't fit this at all, causing her mild humiliation.
• Hate at First Sight: A variation on this, is the irritation with which fellow reincarnators Leon and Marie see each other; it's noted to be more complicated than simple hatred. It's because they're past-life brother and sister.
• Head-in-the-Sand Management: In volume 7, The ruling council of Alzer are like this with regard to Serge's rebellion, with Albergue suspicious but slow to respond, and Lambert Io Feivel a Turncoat.
• Healing Magic Is the Hardest: It's considered rare, taking a lot of study and effort. Marie training hard enough to do it, cost her her body's growth.
• Helping Would Be Kill Stealing: At one point, Leon worries that him getting involved is preventing Olivia from getting the needed development to get through the game's events. Leon was proven wrong later on when Olivia manages to protect an entire ship without any of the key items as Leon (and Marie)'s actions have allowed Olivia to study to her heart's content, which directly affects how well she uses her magical abilities.
  • Ironically, had Leon and Marie not interfered with the game's plot (as is the case with the What If? side story), Olivia actually ends up being unable to find time to study due to the capture targets distracting her from studying.
• Henpecked Husband: Exaggerated Trope, when it comes to male nobles in the matriarichal Kingdom of Holdfort, exemplified by Leon's father Balcus' Marriage of Convenience with Evil Step Mother Zola. It's typical for male nobles to have to accept their wife having lovers, as well as paying her exorbitant amounts of money to spend in the capital. There is a reason this has become the norm there.
• Heroic Lineage: Holfort Kingdom's nobles see themselves this way, being descendants of adventurers. They hardly live up to the belief, although Leon appeals to it in a Dare to Be Badass speech to get demoralized students to fight. This is also why No One Gets Left Behind while adventuring is a law, as well as the spoils of adventuring being protected from seizure.
• Hero's Muse:
  • The five dateable cast tend to go on and on about Marie like this, which doubly annoys Leon, since he both hates her, and was trying to get one of them back with Olivia instead in order to save the kingdom from destruction.
  • Leon later gets very enthusiastic at the chance to stick it to the Holy Kingdom of Rachelle, the main enemy of Queen Mylene's home country. Mylene being Julius' mother, he's naturally disgusted to realize this.
• Hero with Bad Publicity: Leon is an interesting example. Rather than the usual misunderstanding or lies associated with this trope, Leon actively courts hatred out of pettiness and spite. After having originally planned a Zero-Approval Gambit to get expelled by defeating and berating the five most respected noble heirs in the academy fails, and having bet a bunch of money on himself at the students expense, about seventy percent of the Academy hates him. Thus begins a Cycle of Revenge, where the students insult and assault Leon and his property, and he does the same back.
• Hero-Worshipper:
  • When Olivia brings up Leon in her first meeting with Angelica, Angelica reveals herself to be this for Leon, serving as a Commonality Connection between the two. Her father was a renowned adventurer in his youth just like Leon is.
  • In the third volume, after his role crushing the Principality's Capital Offensive, Leon entertains young ladies like this that Leon writes off as wanting him for his status and wealth.
    • Novels after that, reveal that Leon is loved by men of the kingdom in particular for easing their plight, which according to Clarice, isn't always platonic affection.
  • In the sixth volume, when Leon talks to some shop owners, it seems that this is the commoners' view of the Holfort exchange students in general in Alzer, for humiliating their Smug Super High Nobles.
• Hidden Depths:
  • Olivia, despite being The Cutie and seeming like a Wide-Eyed Idealist, doesn't like everyone (in particularly disliking the dateable cast), can be deadly if needed, and due to her intelligence, is able to piece together one of Leon's greatest secrets before anyone else: That Marie is his past-life sister.
  • Marie has strong principles when it comes to gambling, and has talents as a survivalist, cook, and homemaker, owing to her plethora of experience from two lifetimes.
  • The dateable cast, despite all of their Idiot Hero antics, are talented in multiple languages and capable of giving solid political advice, due to their expensive educations.
    • Brad is aware that he's the weakest melee fighter of the five, and trains himself rigorously to correct it.
  • Serge is both a Normal Fish in a Tiny Pond when it comes to fighting ability, due to Alzer's We Have Become Complacent issues, and only half-hearted about his adventuring in order to escape his family issues.
  • The Extreme Doormat Emile, who is somewhat like a Henpecked Husband for Lelia, is predicted by Marie to be actually the most jealous of all of the second-game capture targets, and accordingly becomes subtly controlling of Lelia. He eventually tries to shoot her over jealousy of Serge, and becomes the Final Boss.
  • While Roland seems like a Lazy Bum, when properly motivated, he proves to be Brilliant, but Lazy, impressing even Leon.
  • Leon's younger brother Colin, who seemed to just be there to be adorable, is Wise Beyond His Years and in some ways more mature than his older brothers.
  • Mylene, despite her The High Queen front, Desperately Craves Affection, as Roland gives all of his to his concubines.
• High-Speed Hijack: In the seventh volume, Leon uses the raw thrust of Arroganz to steal the Holy Kingdom of Rachelle's flagship, after forcibly jamming the Holfort flag into it, causing their fleet to retreat from their invasion of Alzer.
• Hijacked Destiny: Marie doing this, becoming the game's protagonist and pushing the original aside, stealing Olivia's game events for herself as well as her Reverse Harem, is a key driver of the beginning arcs. Due to Marie being Locked Out of the Loop from not having finished the game, she doesn't know that Olivia's unique Compelling Voice, as well as True Love, are needed to complete the scenario, neither of which she has.
  • The What If? Marie Route Side Story's premise is this being Defied. Instead of Marie and Julius meetings via Love at First Punch in the game's first event, she gets a double Wall Pin of Love courtesy of Leon.
• Homage: The five dateable cast are this to Super Sentai with them each having a color theme that they're called by, while being Idealistic would-be heroes. May count as a parody, given their Idiot Hero nature.
• Homefield Advantage: The Sacred Tree of the Alzer Republic effectively grants their ships limitless power within their borders allowing them to overwhelm any invasion force and earning them a reputation for being undefeatable in a siege battle. This also swelled the heads of their military and nobles with many openly looking down on foreigners who visit their country. Getting an entire fleet utterly annihilated by Luxion, commanding a single ship, in volume 4 quickly dissuades them of their notion of invincibility.
• Homing Lasers: Luxion's main body can fire these. Later, the Combining Mecha attachment he makes for Arroganz lets it fire them, but at the cost of draining its power reserves rapidly.
• Honest Advisor: Jenna gives a lot of useful social and political advice to Leon and Olivia, even if being rude and insulting while doing so. For instance: If Angelica wanted Marie dead, she would be dead, because that's how powerful a ducal household is. That advice in particular, has a large impact on the plot, and Leon's relationships.
• Honest John's Dealership:
  • After they all lost to Leon, the five princes pool all of the funds they can find, to build a mech out of the parts of their previous ones. The problem was, they hired a fraud to assemble it, leading to it overloading and nearly killing one of them, and forcing Leon to destroy it after he had planned on Throwing the Fight. This leaves Marie in despair, as they have no living expenses and there's no wreck to salvage.
  • The merchant who took Kyle from his home village, conveniently hid the fact that he was a half-elf, and sold him to the market at full price. A fact which could have resulted in a Surprise Pregnancy, since one of the main uses of Exclusive Servants is as lovers, and half-elves can get human women pregnant, unlike full elves.
• Horrible Judge of Character: Lelia Beltre. Her playing through the second game and seeing the true end has basically given her confirmation bias towards Loic. She's convinced that everything will work out as long as Noelle ends up with Loic and ignores or only reluctantly acknowledges all of Loic's flaws while only needing a few paper thin excuses to jump back to her previous mentality with barely any hesitation.
• Host Club: Marie's "Cafe" during the second volume's School Festival, is styled like one of these, with the five idiots wearing tight-fitting suits. The Marie Persevering side story shows that Marie got the idea to do this by following some noble girls until they walked into a professional host club.
  • In the Luxion and Cleare's Marie Study side story, she brags about being the #1 ranked girl at her Hostess Club in her previous life. It helped that she was much more developed in that life.
• Hostile Show Takeover: Marie's goal was to replace Olivia as the protagonist and get all the possible love interests of the game to fall for her instead. It doesn't go exactly as well as she hopes because Leon, who notices her being a reincarnator as well, decides to intervene. As a side effect, the would-be protagonist Olivia befriends Angelica, who would normally antagonize Olivia in the game's plot because she would be the one Julius was infatuated with.
• Hot Springs Episode: Near the end of the first volume, when Angie and Livia spend their school break at Leon's home territory, where he had Luxion build a spring.
• Hourglass Plot:
  • Within the second volume: Hertrude goes from gloating and having the captured Angie Forced to Watch Leon be attacked, while Angie talks back defiantly, to being captured herself and Angie forcing her to watch The Black Knight fight Leon, while Hertrude talks back defiantly.
  • Jenna goes from having free pick of noble men to marry, while Leon had to suffer looking for marriage, to herself suffering looking for marriage while Leon gets buried in engagement requests.
• Humanoid Abomination: Some Evilutionary Biologist elves used left over laboratory equipment to create these that attack Leon on sight. They're noted to be the first monsters he fights that aren't Reduced to Dust. This is because they're derived from the Old Mankind Precursor mechanical technology, instead of New Mankind's Organic Technology.
• Humble Pie: Julius, after being kicked out by Marie alongside the other capture targets for pilfering half her money, blows most of his money celebrating the first day. Upon realizing he's almost broke, Julius is shocked to discover that all four of the others are more successful on their own than him. He runs away to wallow on a bench, homeless, only to finally get his hands dirty working for a stand, and winds up winning the challenge Marie offered to the five of them because of the perspective he gains.
• Hungry Weapon: The Black Knight's Absurdly Sharp Blade feeds on blood, prompting Leon to refuse to use it.
• Hypocrisy Nod: Leon sometimes makes these, when not giving sarcastic replies to being called out.

I-L

• Identical Stranger: Exploited Trope. To Albergue and Louise Sara Rault, Leon is basically their dead family member in the flesh, complete with the same face, first name, taste in food, and the approximate age he'd be if alive. Thanks to this, Leon has the political backing of leading family of Alzer, and also tries to use it to persuade the Brother Complex strucken Louise, not to sacrifice herself to the Sacred Tree, unsuccessfully.
• I Didn't Mean to Turn You On: Tends to happen with the Bunny-Ears Lawyer Roseblade sisters.
  • Leon's belittling of Deidre Roseblade ends up turning her on. She soon after speaks fondly of "his abuse" in front of Leon's parents and siblings.
  • Nicks, under his younger brother Leon's guidance, trying to scare away Deidre's older sister Dorothea Roseblade from their impending Arranged Marriage with a Slave Collar, just makes her fall for him.
• Idiot Ball: The main plot of the fifth volume only happen because characters arbitrarily withhold important information from each-other.
• Idiot Hero: The five dateable cast are generally like this as comic relief, though they have their moments to shine.
• If I Can't Have You…: Loic tries to strangle Noelle to death, after she can't give him the Guardian Crest at their wedding, judging that her inability to do so was due to her feelings for Leon.
  • Jealousy over Serge and manipulation by Ideal ultimately cause Emile to empty a handgun at Lelia, who Clement and Noelle end up Taking the Bullet for.
• Impeded Communication: The special particles that monsters are made of, block signals in high concentrations, which can leave Leon unable to communicate with Luxion (since the sphere drone that follows him is merely a terminal.)
• Implausible Deniability: Leon denying that he has a sister fetish looks more and more like this with Louise over the course of the later volumes.
• Impoverished Patrician: Most of the Baron and Viscount households have been drained of their wealth over several decades, by the preferential treatment given to the women of the family, who live expensively in the capital. Marie's family is a particularly egregious case, due to her parent's gambling addiction, leading to Marie hunting and foraging to get by.
• Incest Subtext: In some of the side stories that came with certain editions of the third volume. Especially for the Leon's Score Result story: Leon and Marie's scores on the Royal Airship's love gauge are 81 for Leon, and 84 for Marie. That story, as well as Marie's Olivia Study, both have Marie feeling like she lost out by going for the five idiots instead of Leon.
• Indecisive Parody: The series can't quite decide if it's trying to be a straight Isekai Harem Series or a parody of same. The series has a Genre Savvy First-Person Smartass for a protagonist who frequently comments on the bizarre logic or lack thereof common to the Otome Game genre, and who unknowingly becomes the butt of the joke by sending the game plot Off the Rails and never internalizing that he's now The Hero instead of the background character he thinks of himself as. At the same time, it does play a lot of genre conventions of the male-centric equivalent very straight: Leon is still very much a Power Fantasy character who uses out-of-game knowledge of the world and storyline to achieve his ends (at least for the first game, and only in cases where his own actions haven't altered things).
• In Love with Your Carnage: Deirdre reacts this way about Leon delivering a No-Holds-Barred Beatdown, which reinforces his belief that she's a pervert.
• In-Series Nickname: Several:
  • The five dateable cast of the first Otome Game are called the five princes, or the five idiots, by Marie and Leon; technically only Julius is a prince. As well, Leon has a habit of calling them by their hair colors, which they react badly to.
  • Angelica and Olivia are known by those close to them as Angie and Livia.
  • Olivia dubs Luxion and Cleare, Lux and Are-chan.
  • Marie uses the In-Universe fan nicknames for the second Otome Game's dateable cast, mainly calling Emile Safe-Tile Emile, Loic Royal Road Loic, and Hugh is for some reason Brocon Hugh.
• Inside Job: In the second volume behind the scenes, the Principality's ambush of Leon's field trip was this. Frampton conspired with Duke Redgrave's vassals to have their children send smoke signals to help the Principality fleet track their airship, and with Earl Garrett, to make sure that Angelica was the only survivor, so that Frampton could accuse the Redgraves of collaboration.
• Instantly Proven Wrong: In the Manga. After Leon was promoted to Baron, meaning he will have to marry a woman of higher class, he flat out says those women are a minefield. His father asks if he means his own sisters as well and refuses to believe that his daughters are anything like that. Said daughters then barge into the room, complain to their brother and demand that since he is now rich that he should give them an allowance. The father, seeing this, is no longer able to defend them and facepalms.
• Internal Reveal: While it's very strongly foreshadowed prior that Marie is Leon's past life little sister, the characters don't find out until much later.
• In the Blood: It's noted that being Brilliant, but Lazy is in the Bartfort family blood, which surprisingly enough also applies to Jenna.
• I Resemble That Remark!: Leon foils an attempt to persuade his sisters in the eighth volume. When they accuse him of being unfaithful, he tries to shut them up by emphasizing he has three fiancées, proving their point.
• Ironic Hell: In some respects, being trapped in the Otome Game world is this for Leon. Playing the game, Leon sold each and every gift that the guys gave to him, right while they were in his active party. Leon ends up giving gifts to the girls in the academy who do that exact same thing.
• Irony:
  • Once Leon finally starts being courted by noblewomen, their offers are all over-the-top selfish, so Leon can't help but laugh that the one exception who bothers to consider HIS needs and desires, is the duplicitous enemy head of state Princess Hertrude.
  • It's repeatedly discussed that the Final Boss of the second Otome Game is Albergue Sara Rault. He winds up being Alzer's Big Good instead, due to Leon being identical to his dead son.
  • The What If? Marie Route Side Story makes a certain plot very ironic: In the main story, there is a crisis, and Angst over Leon's treatment of Olivia, and if he's hindering her growth. However, it turns out, in a world where Leon and Marie don't usurp her role, Olivia is weaker, both in power, and in spirit, to disastrous effects.
  • In the eighth volume. Leon explains that Cleare is a much more reliable and trustworthy A.I. than Luxion. But she by that point had already been a Spanner in the Works by turning one of the third game capture targets into a woman.
• I Want My Beloved to Be Happy: Angelica and Olivia's wish side stories about the marriage shrine visit, both involve them thinking this, regarding Leon getting with the other.
  • Colin in the eighth volume settles on this as the answer to his Unrequited Love.
• Japanese Delinquents: While the setting of the games is clearly based on western noble culture and usually succeeds at mimicking that, the use of these sticks out. Most of the examples are nobles themselves, except for Aaron and his friends in the fourth volume.
• Jeanne d'Archétype: The Kingdom of Holfort's main religion worships a female adventurer saintess who was key to the Kingdom's unification. Leon wasn't interested in the game's lore, so his knowledge about her is vague, only caring that Olivia is descended from her. Her story is explained more in the Marie Route SS, where she's revealed to be named Anne.
• Jerkass to One:
  • Second game villainess Louise is this to Noelle and especially Lelia despite seeming quite nice otherwise, which is given proper explanation. She develops towards being Vitriolic Best Buds with Noelle at least.
  • Dorothea Roseblade secretly terrorizes Jenna out of anger of having overheard Jenna trash talk her beloved, Nicks.
• Katanas Are Just Better: Leon ends up using one, due to Luxion making one for him as a Secret Test to see if he was really Japanese.
• Kill All Humans: Luxion holds a grudge against the "New Humans" who destroyed his creators, new humans being any human able to use magic. Leon (and Marie) are exceptions due to somehow having old human DNA mixed in, as well as past life memories of Old Humans.
• Kiss-Kiss-Slap: At the end of Volume 3, Angie and Livia confess to Leon again and tell him to choose. He chooses both of them, which earns him a slap. Then they both get engaged to him as the wife and mistress and are happy with the arrangement.
• Kneel Before Zod: Marie, feeling full of herself from being declared Saint, tells Angelica and Olivia to kowtow to her publicly if they want her help, looking forwards to Angelica being too prideful. Only for Marie to end up absolutely terrified when Angelica does do it, and Marie realizes it will put Leon into an Unstoppable Rage.
• Knighting:
  • Leon was knighted for defeating the five idiots, as a result of Duke Redgraves actions to honor his agreement to shield Leon's family from retaliation, and selling him as an underdog hero.
  • The prologue chapter of the fourth volume shows that Olivia has been knighted for her role defeating the Principality of Fanoss.
• Knight in Shining Armor: What Master teaches Leon to be, motivating him to fight on for the sake of those he wants to protect, during a Heroic BSoD. Master himself, protects Mylene and Hertrude from rubble during a Principality raid, and later leaves to join the final battle himself.
  • Olivia sees Leon this way, despite everything. There was even a manga extra that consisted of all the characters reacting to her saying this with laughter.
• Lady Land: In the Holfort Kingdom, the nation that Leon reincarnates into, women pretty much have the upper hand in relationships, despite there being more women than men. As it turns out, this is due to a botched social engineering attempt to control the nobility and prevent them from warring with each other, and eventually centralize authority in the capital. After the war with the Principality, the pro-female system begins breaking down.
• Lampshade Hanging:
  • Leon's repeated asides of Who Writes This Crap?! lampshade that the franchise is Darker and Edgier and more violent than otome games, or most other otome isekai.
  • A Find Out Next Time message at the end of a manga chapter, lampshades that Leon and Luxion bicker Like an Old Married Couple.
  • In the manga version of Chris's conversation about his father with Leon, Luxion lampshades that Leon has his own inferiority complex, despite criticizing the princes for theirs.
• Language Barrier: Downplayed in Volume 4. Leon and Marie initially struggle with the Alzer Republic's language, but quickly have no problems keeping up in school or communicating with the locals. It helps their guides are perfectly fluent in Holfort's Common Tongue, Leon also has Luxion translate, and Marie gets plenty of help from her noble boyfriends, who already know multiple languages.
• Laser-Guided Karma: It's virtually a physical law in the story for the selfish to eventually get their comeuppance. Leon isn't immune.
• Late-Arrival Spoiler: A number of advertisements use artwork spoiling the first three volumes by showing Leon at his engagement ceremony with Angelica and Olivia.
• Laughing Mad:
  • Leon becomes like this when, after trying to be polite while being bullied and having his café trashed, the Queen being in danger finally gives Leon a pretext to confront his assailants.
  • Pierre does this during a Kick the Dog moment where he destroys a bar and terrorizes the family who run it.
  • Loic later gets like this, when rampaging against Hugh who's fleeing Loic's crashed wedding.
• Leeroy Jenkins: When Leon played the game, Brad being both a Squishy Wizard and Boisterous Weakling charging into melee caused many Game Over screens, leading to Leon developing strategies around keeping Brad contained, and holding a grudge.
• Legacy Character: The Masked Knight superhero identity is unwillingly handed over by King Roland to his son Julius, when Julius steals all his equipment to fight, after being forbidden to. Julius discovered it in a secret passage as a child. The other four princes never figure out it's Julius despite it being a Paper-Thin Disguise.
• Leonine Contract: In Alzer, duels made under the tree's vow, can be made in very unfair terms; this is part of what gave Alzer nobles such a stranglehold over commoners. A literal stranglehold: If a non-noble breaks a vow, roots put around their neck by the tree, decapitate them. If a noble breaks it, they are de-powered, and their descendants can't recieve a crest.
• Lethal Joke Item: The kingdom's secret airship is basically a gag for a marriage that gave couples a score of their love. It nevertheless saves the kingdom from a giant summoned monster.
• Lightning Bruiser: Both Leon's Mini-Mecha Arroganz, as well as the mechs used by the Black Knight.
  • Later, Luxion builds mechs for each of the Five Dateable Cast comparable to Arroganz, leaving Julius astonished with their performance.
• Like Father, Like Son: Leon's father Balcus is Brilliant, but Lazy, usually only putting in real effort when loved ones are in danger. This was passed down to his sons Leon and Nicks, to different degrees.
• Like Parent, Like Spouse:
  • Angelica's father is a greatly accomplished adventurer, with a blunt manner, who isn't afraid to get in the thick of battle, and is ruthless to those who cross him. So it makes sense that she already has a strong admiration for Leon before getting involved with him.
  • Part of the reason why Julius fell in Love at First Punch was because the only other woman who'd ever slapped him was his mother. Olivia/Marie's lines during that game-based encounter are also scolding him just like his mother does.
• Living Battery: In Alzer, the ancient Living Weapon Mini-Mecha unleashed by Ideal, tricks Louise into giving herself up as a Human Sacrifice, and being a conduit to recharge itself, through her Sacred Tree Crest, convincing her via Dead Person Impersonation of her late brother. Leon breaks her free of it, only for it to be suspiciously rescued by Ideal.
• The Long Game: Downplayed with Leon. When he goes into his Tranquil Fury, he becomes patient and calculating like this, as explained with an anecdote from his past-life about how he dealt with some school bullies.
  • In the seventh volume, this is the backstory for Ideal, his actions as the Big Bad being a Roaring Rampage of Revenge for all of his Old Mankind friends being killed.
• Lost Technology: The Lost Items, which are the remnants of an ancient civilization, implied to be a future Earth All Along.
• Love at First Punch: Marie beats up Loic twice, giving him a Do Not Go Gentle speech with the second. This causes Loic to stop being a Death Seeker, and makes him fall for her, completing his Heel–Face Turn.
• Love Epiphany:
  • Angelica's Green-Eyed Epiphany during the Angie's Wish side-story set during the marriage shrine visit.
  • Colin has one of these at just the worst possible moment. Love Hurts indeed.
• Love Hurts: The story has recurring instances of unrequited love, which always has severe consequences:
  • Angelica one-sidedly loves Julius, who is engaged to her. He is dismissive and condescending to her, and loves someone else. While Angelica tries to convince herself that it's normal for a high ranking noble to have a mistress, seeing Marie hold a man besides Julius' hand to provoke her, sends her into a rage, challenging Marie to a duel. After Julius loses and is disinherited, emotional support from Olivia and Leon help her move on.
  • Jilk's fiancée Clarice was in love with him, only to have their engagement ended by a "Dear John" Letter. This causes Clarice to send her fanatically loyal followers to attack Jilk, with the pain causing her to stay up all night with Exclusive Servants. She moves on after Leon uses a favor to get Jilk to apologize.
  • In Alzer, Noelle falls for Leon, fantasizing about a future together, only to see two fiancée she didn't know about, and see him looking at them in ways he doesn't to her. Noelle gets depressed, and this causes her to reject rescue attempts, after she's blackmailed by Loic into getting married. She gets over it after her rival Louise convinces her that her feelings are reciprocated.
  • Colin's Character Arc in the eighth volume revolves around him coping with Unrequited Love.
• Love Ruins the Realm: The original game's datable cast inevitably cause this, due to placing their Love Interest above all else. In the case of the main story,they wind up disowned because they refuse to abandon Marie, inadvertently causing a huge shift in the political structure of the kingdom that throws things into chaos.
• Love Triangle:
  • The first three volumes develop one between Leon, Livia, and Angie: he befriends both girls and encourages a friendship between them as well, partly out of a desire to avoid storyline-related disaster and because he thought the game's Protagonist-Centered Morality did Angie dirty. He unintentionally winds up with both girls falling in love with him by volume 2, with the twist in volume 3 that they've also simultaneously fallen for each other, turning their eventual engagement into a three-way group relationship.
  • The sixth volume introduces a somewhat violent one between Emile and Serge over Lelia. It ends with Serge and Emile both dying, with Lelia stuck as The Atoner for her mistakes.
• Loving a Shadow:
  • Angelica spent her entire life before the beginning of the plot, being trained to be a good wife and queen for Julius. She is constantly trying to make Julius more into what an ideal prince should be, rather than listening to his true feelings. Angie's father and brother discuss this, in relation to her later relationships; she doesn't have a good understanding of love, or her own feelings.
  • In Alzer, Loic had been a Control Freak, constantly telling Noelle what she should like and do, and not listening to her true desires, driving her away from him. After Loic becomes a Crazy Jealous Guy and blackmails her into an engagement with him, she eventually makes him realize this with a "The Reason You Suck" Speech.
• Low Culture, High Tech: Comes with the setting being a Feudal Future, they use Magitech, with feudal knights wielding Mini-Mecha developed from Lost Technology, that fly thanks to Applied Phlebotinum, and depend on the user's magic to operate. All while the governing systems resemble medieval England, with Old-School Chivalry being prominent (if a bit warped).
• Lower-Deck Episode: A side story with the eighth volume shows the perspective of events from the point of view of commoners and retainers in the Bartfort territory, as well as Leon's sister Jenna. Their expectations based on the past, show just how much the Kingdom has changed over the course of the story.
• Low-Tier Letdown: In-Universe, Leon's view of the five love interests, as they were terrible units for the later stages of the game, leading to many game overs. It is one of the reasons why Leon enjoys dueling them, as he is partly venting his frustrations. This is also why in their past life Marie forced Leon to beat the game, as she was stuck due to the unforgiving difficulty.
• Luke, You Are My Father: Erica, Julius's sister and the "villainess" of the third game, reveals herself to be a reincarnate. But not just any reincarnate, she's Marie's previous-life daughter. Of course, she doesn't reveal herself as such until Marie mentions how Leon died after playing the first game, confirming to Erica that Marie was her mother.

M-O

• Machine Worship: Downplayed with the religious fear that Luxion inspires into the Elves of Kyle's home village, who call him The Demon Lord.
• Mad Scientist:
  • The Evilutionary Biologist elves Leon finds within the elven ruins.
  • Noelle and Lelia's father was a cold and manipulative one of these, who invented Loic's magical Slave Collar, amongst other things. This came back to bite him, in multiple ways.
• The Magic Versus Technology War: The backstory of the world with the magic/new humans side winning.
• Magitech: Common, such as guns using magically charged bullets, or Brad using magically controlled attack drones in his duel with Leon.
• Maid Corps: Angelica and Dorothea each have one, which comes with being a High Noble. With Angelica's, since they were mostly staffed by the daughters of her father's vassals, they end up being short-staffed due the Vince launching The Purge of them for their betrayals of Angelica.
• Malicious Slander: After an incident where Leon throws his terminal as a weapon, and doesn't apologize, Luxion takes up the habit of wildly exaggerating Leon's "sins" to his Love Interests.
• Mama's Baby, Papa's Maybe: In the light novel Leon points this out as why Marie's harem is a horrible idea. When Marie eventually has a child, they will have no way to know who is the father since all the boys are dating her at the same time. An already awkward situation made worse when Julius will have to name one of Marie's children as his successor causing unrest because no one will be sure if his successor is even his child. Luxion even wonders how nobles can stand it since it's common for richer noble women to have multiple husbands. It's revealed in the third novel that many of Holfort's societal problems, including this one, were engineered by the Royal Family many generations ago and coded into the kingdom's laws and customs as a Long Game strategy to saddle other Noble Houses with one Succession Crisis after the next with the objective of slowly but surely weaken them all and centralize power as an absolute monarchy in the future. Some of the High Nobility have realized this and made a point to raise their daughters accordingly, which is why girls like Angelica and Deirdre don't Really Gets Around like lower-ranked noblewomen can easily get away with.
• Marriage of Convenience: Leon's greatest fear is being forced into one of these based on noble status like his father Balcus had been with Rich Bitch Zola (Leon's the son of his father's mistress, Luce). Most marriages between nobles are planned around how the marriage would advance their future or families, with many men in the academy being in a "race" to get engaged before all the nice women are taken. Luxion picks out an especially egregious marriage negotiation letter Leon receives, that requested he house and care for several lovers.
• Mass "Oh, Crap!": Leon launching an assault causes one in the sixth volume.
• Master Swordsman: Chris is officially one of these, at a young age, while his father is the kingdom's Sword Saint. The Black Knight beat Chris' father in the past.
• The Matchmaker: It becomes more and more apparent that Duke Redgrave (Angie's father) is trying to pair off his daughter with Leon, especially once Leon starts to rise in the ranks of nobility and it becomes apparent that Angelica fell for him. He even decides to "punish" Angie for her disgrace (kowtowing in public) by marrying her off to a knight that threw away his rank, peerage and territory (Leon). He also isn't against having her friend (Olivia) share the same man. Angie is understandably delighted at this.
  • Later in the series, Luxion starts up a bad habit of scheming to push Leon into a series of new relationships; whether these setups are for Leon's own benefit, or to sadistically watch him squirm, is hard to say. First, he gathers evidence of Leon's feelings to convince the respective families to corner Leon to an engagement with Angie and Livia. Secondly, Luxion Arranges for Angie and Livia to walk in on Leon close together with Noelle, with a Slave Collar around her neck tied to his wrist, and a baby carriage in the room, to force them to confront their feelings.
  • We learn in the eighth volume that Clarice has been doing this for her friends and followers; we're introduced to a freshman girl Clarice saved and paired with the muscular follower who saved Leon from his exploding air bike. Because of the disparity in rank between any of them and her, she cannot find a husband for herself, however.
• Matriarchy: Holfort Kingdom's nobility run on a matriarchy despite men still being responsible for being the primary provider and duty to fight and die for the kingdom. Interestingly, this is not quite the case in the highest ranks of nobility and the royal family. It was speculated that the upper nobility caught on to the reason for the push in the beginning, namely the eventual abolishment of the nobility and the uplifting of the commoners.
• Meaningful Echo: Marie's Inner Monologue during the Marie's Academy Life side story from the first volume, where she thinks that Olivia is the type of girl who makes men "dance on the palm of her hand", proves interesting, considering the Marie Route, where that line is used again by the Vengeful Ghost Anne possessing Olivia. Marie accurately judged Anne's personality from playing the game, and wrongfully attributed it to her host.
• Meaningful Name: The fact that most character names are European despite this being a Japanese work allows for some interesting Bilingual Bonus based on how the letters L and R are interchangeable in romaji:
  • Zola can also be translated as Zorra, which is Bitch in Spanish, fitting her being a Rich Bitch.
  • Jilk can be translated as Jirk, as in Jerk, fitting him being the Token Evil Teammate.
• Mecha: Used all over for battles and duels. Most have sleeker designs to emphasize speed, but Leon's Arroganz is a Lightning Bruiser that looks like a Mighty Glacier.
• Media Transmigration: The protagonist is a salaryman who dies of exhaustion after being blackmailed into a 48-hour straight gaming session to clear an otome game for his selfish younger sister. He is then reincarnated into the game's world as a background extra or "mob character." Recovering his memory of his past life after some ten odd years, he goes about trying to eke out a peaceful life for himself in a matriarchal society where men are mostly only seen as good for either being trophy husbands or fodder to die in wars. Later on he runs into Marie, who happens to be the reincarnation of his younger sister, but doesn't discover that until after she attempts to manipulate the events of the game in her favor.
• Men Are the Expendable Gender: Luxion notes that there is a huge unbalance of the men to women ratio with many men dying in wars or against the many monsters that exist in the world. It should be stated that nobles aren't an exception as many nobles are adventurers as well with the kingdom placing great value is strength and martial skill. This bites the Kingdom hard when most of them defect out of not wanting to preserve such a status quo.
• Metaphorically True: Ideal likes to use half-truths and exaggeration to manipulate others.
• Mind-Control Eyes: Yumeria when she's mind-controlled by Ideal.
• Misery Builds Character: Many of the character's lives are improved by their realizations from their Break the Haughty moments. Angelica is happier setting her own goals, both she and Greg Took a Level in Kindness, and Julius becomes humble and helpful.
  • Leon was trying to do this to the five princes when dueling them, not realizing he was contributing to them being disinherited. He knew their flaws from the game and mercilessly prodded at those, but admits, he got a bit carried away having fun playing heel.
• Mistaken for Cheating: It's a Running Gag that Leon gets mistaken for trying to make moves on Marie, due to them spending time alone together to speak about reincarnator-related topics which they're keeping secret.
  • Leon's father is mistaken for cheating on Luce with Marie's mother due to another misunderstanding.
• Mistaken for Gay: The very beginning of the story has Leon's past life sister storing Yaoi in his bedroom and their parents discovering it, getting him kicked out since his parents trust her more than him, and her offering to clear up the misunderstand only if he beats the Nintendo Hard Otome game for her.
• The Mistress: Leon's mother Luce is technically this, although in terms of how the Bartfort Household functions, it'd be more accurate to say Luce is the wife and mother, while Zola is the Bad Boss.
  • When Leon is tricked into getting engaged, Olivia is also engaged to him as this; since it's Angie who's to be the Legal Wife, she doesn't mind.
  • Vince and Gilbert Redgrave try to assign one of their maids to be this for Leon, while he is in Alzer away from Angie and Olivia, thinking it'd be better than him getting involved with Marie or anyone too important. But Cordelia volunteers herself, and serves as a self-appointed faithfulness watchdog, instead.
• Moe: In-Universe—Leon, after spending time with Olivia, says he understands why her Love Interest would want to protect her. He also finds the Queen absolutely adorable and actually uses the term "gap moe" to describe Noelle. Marie deliberately fakes being this for her Reverse Harem, who mention they can't help but want to protect her.
• Mood Whiplash: Since the eighth volume, a Breather Episode, and the sixth part of Marie Route, a blood soaked Wham Episode, were released alongside each-other, anyone who was keeping up with both timelines faced this.
• Morton's Fork
  • At the height of his arena match against Leon, Prince Julius declares a Duel to the Death to force Leon to surrender or face severe consequences for killing the prince. However, Luxion calculates the exact amount of force needed to knock him unconscious but still alive.
  • In Volume 4, Leon forces one on the Alzer Council. They can try to blame him for the destruction brought by the Einhorn (which he and Luxion framed Pierre for), which would also stain their international reputation. Or they can apologize and pay him for all the damages along with some hush money to keep him silent. Acting Chairman Albergue quickly agrees to compensate him, to Leon's surprise.
• Motive Rant:
  • During the duel between Julius, and Leon (who's playing heel as part of a Zero-Approval Gambit), Leon meets Julius' rant with one of his own. It serves to discredit Julius since his complaints are from a position of absolute privilege, unlike Leon who's suffered from the Fantastic Caste System. Leon's rant also earns him admiration from those who've suffered the same.
  • In the third volume, Marquess Frampton goes on during his Villainous Breakdown after being publicly accused and arrested, about how everything is about him, and how he sees Leon as the real threat to the Kingdom.
  • The second game villainess Louise goes on one over her bullying of Noelle and Lelia, after she lunges after Lelia, and Leon gives her a Cooldown Hug.
• Ms. Red Ink: Male-variant. Marie's Reverse Harem does not know how to manage money well. Ironically, it's because they want to please Marie so they buy expensive stuff thinking that would make her happy. When they see her unhappy with what got her they think they chose the wrong gift.
  • Marie Route reveals that her next-life older sister being this is part of the reason her family is in so much debt on top of their gambling habits.
• Mushroom Samba: The All Just a Dream side-story in volume 8, where Cleare tampers with Leon's sleep medication and makes him dream of a Distaff Counterpart to himself and Luxion.
• My Country, Right or Wrong: Discussed Trope, in Leon's discussions with Princess Hertrude. He hates the Kingdom because of its treatment of men and poor nobles. But it's also where all of his friends and loved ones live.
• My Friends... and Zoidberg: Leon tends to give Marie this treatment, and to a lesser extent, Noelle.
• My Sister Is Off-Limits: Subverted in the seventh volume. Leon is happy with a reformed Loic courting Marie, despite the five idiots pleading with Leon to intervene.
• Mythology Gag: The elven Fortune Teller speaking about Marie having passed by her chance to be with her One True Love is a reference to the Marie Route Alternate Timeline and its beginning scene.
• Named by the Adaptation: The name of the titular Otome Game is never mentioned in the novels/manga. In the anime (and in the web novel), the game's title is Alto Liebe.
• Nasal Trauma: Inflicting this, is Angelica's response to Earl Offrey's daughter repeatedly damaging her relationship with Olivia. It clearly wasn't enough.
  • Loic also gets this from having Luxion thrown at him.
• Neck Lift: Earl Offrey's daughter learns the hard way not to threaten Angelica's friends.
• Never My Fault: Played With. In Marie's Inner Monologue, she constantly blames her past life brother for everything, at least at first. She gradually comes to the realization that he was actually the only person to genuinely look out for and care for her from her past life. The hatred was mostly driven by Leon's resemblance to her previous life brother combined with his antagonism towards her.
  • Lelia can only blame everyone else around her, instead of acknowledging her own mistakes, driven by a deep resentment of others success. Until her My God, What Have I Done? realization.
• New Life in Another World Bonus: Leon completed the otome game, so he knows where to locate the spaceship Luxion, which was a cheat item in the game, in order to secure his future in a woman-dominated kingdom and get out of an Arranged Marriage to an older woman.
• Nice Job Fixing It, Villain:
  • Marie's interference of the story actually benefits Olivia a lot. As she didn't have to deal with any of the 5 capture targets, she was able to spend her time in the academy relative peace studying to her heart's content. This causes her overall potential as a Saint to be higher than it was in the game, allowing her to perform her game counterpart's feats without any of the key items.
  • And as revealed by the Marie Route, Olivia not getting any of the key items is actually for the best as she was able to avoid getting possessed.
  • During the school festival, the daughter of Earl Offrey has her servants rough up Leon and his friends, knowing that any boy seen fighting an Exclusive Servant would be unable to get married. However, when a lady protests their actions, the daughter has servants confront the lady. This gives Leon the excuse to start fighting back, as the lady in question was in fact the Queen traveling incognito.
• Nice to the Waiter: This is used to establish that Clarice is nicer than she first seems. Contrasting to what most Royal Brat girls in the Academy would do, Clarice takes extremely good care of her followers, making sure they have good futures, and not caring that they're lower ranked, earning their Undying Loyalty.
  • This aspect is used, especially in the third volume, to show how despite her spiteful and selfish thoughts, Marie shows a caring side when it comes to Kyle and Carla.
• No Endor Holocaust: The "good" ending of the second game Mobuseka's world is based on is one of these, which becomes an important Plot Point in the Alzer Republic Story Arc that keeps Leon from simply having Luxion destroy the Sacred Tree before the Arc Villain can use it as the game's Final Boss, as doing so would trigger the severe natural consequences that the game's writers didn't bother to consider. The Sacred Tree is the very core of the Republic's economy, meaning that even if the game's protagonist and her Love Interest manage to rescue a sapling that will become a new Sacred Tree, it won't grow fast enough for the Republic's economy, if not the country itself, to not collapse in the meanwhile. Worse, the Republic is the main exporter of Suspension Stones—-the core component in this world's flight technology, made even more crucial because people live in Floating Continents—-thanks to the Sacred Tree, meaning that its destruction would trigger a global logistic crisis and most likely a global armed conflict in turn.
• No Hero to His Valet: Leon is no hero to his second-life sisters, who see all of his flaws and are baffled by the fame and affection he gains.
• No-Holds-Barred Beatdown:
  • In the second volume, Angelica's followers surprise attack Leon from behind and give him one of these, until Olivia forces them to stop.
  • Leon administers a guilt-free one of these to Pierre. And There Was Much Rejoicing by the commoners who had been living in fear of Alzer noblemen.
• No Name Given: We never learn anyone's original Japanese name. Leon mentions he can recall most of his Past-Life Memories except for the names.
• No One Gets Left Behind: Since the Kingdom of Holfort was founded by adventurers, anyone who abandons their comrades adventuring is stripped of their nobility.
• Normal Fish in a Tiny Pond: The Alzer Republic's over-reliance on their Sacred Tree blessings and disdain for adventuring have atrophied its people's physical and fighting abilities. Without this Homefield Advantage, Leon and the Five Datable cast are practically a One-Man Army compared to everyone in the Republic. Even Brad is able to fight off multiple Alzerian assailants with just his fists.
• Nose Bleed: In the Drama CD, Leon gets an aroused nosebleed from Luxion's simulation of Livia and Angie beginning a sexual encounter. Before being forced to clean.
• Not Like Other Girls: In the Marie's Academy Life side story, Julius says this to her. Considering that was just after she knocked him down with a mere slap, and then carried him inside because his legs wouldn't work, he's pretty justified in saying it.
• Not So Above It All: It's easy to see Angelica and Olivia as entirely above the sort of idiotic antics perpetrated by the five princes to please Marie, but that is not the case: On two separate occasions, they make an Epic Fail of attempting to seduce Leon, by laying in his bed pretending to be asleep. After the second time, Noelle explains several alternatives, and reasons why that was a horrible plan.
  • In the seventh volume, Only Sane Man Adorably Precocious Child Kyle goes through a rebellious phase.
• Not So Invincible After All: The Alzer Republic, who are known for never losing a war due to the power granted by their World Tree, get a harsh wakeup call after the protagonists get to work.
• Not What It Looks Like: Leon has an old baby carriage in his house from when he took care of a sick dog, and Noelle has a magical Slave Collar attached to her neck and Leon's arm, from when she was rescued from Loic. Luxion arranges for the chain to be summoned, Leon and Noelle close together, and the carriage to be present, when Leon's fiancées walk in, to make it look like Leon was caught cheating.
• Nouveau Riche: The notorious Offrey Household, who bought and usurped their Earldom. Their main presence is in the form of Earl Offrey's bullying daughter, who flaunts several Exclusive Servants and is noted by multiple people to be gaudy.
• Number Two: Gilbert Redgrave serves as this for his and Angelica's father Vince, acting as his spokesman and enforcer.
  • In Alzer, there's a double example: First, Marie goes from being The Rival to The Lancer to Leon in his adventures. Secondly, Carla Fou Wayne serves as Marie's number two when managing the five idiots and their shared household.
• Off the Rails: Justified. All told, a total of three people from modern-day Japan reincarnated as background characters in the setting of a Science Fantasy otome game series, and used their out-of-game knowledge to their advantage: Leon hijacked the spawn point for the first game's microtransaction store to get a noble title in his own right and avoid the Arranged Marriage from Hell, Marie usurped the role of the first game's protagonist Olivia to pursue the Reverse Harem route in hopes of an easy life, and Lelia did similar things in the Alzer Republic of the second game. The problem is, none of these characters actually have complete knowledge of the game world (Leon is the only one of the three to actually beat one of the games himself and died before the other two came out, while Marie and Lelia just watched the cutscenes and read online walkthroughs), and real people react differently than video game characters following a script. This means that their interference and competing gambits gradually tie the storylines of the games in knots: they end up having to beat the final boss of the third game in the first game's timeframe, and by the time the third Story Arc comes around, none of them have any idea what's going on anymore.
• Offing the Offspring: Luxion's research discovers that the World Tree granting magical benefits to Alzer does everything it can to kill off its saplings. Why it does so, is a mystery. For example, it powers up Loic's mech to an abnormal degree, to give him an advantage against Leon, the sapling's Guardian, during their duel.
• Oh, Crap!: Marie was paralyzed with fear, accurately realizing the reaction Leon would have to her making Angie and Olivia publicly kowtow to her in exchange for help, which she didn't think they'd go through with.
  • The five princes when seeing The Black Knight's Living Weapon Bio-Armor, and its Extra Eyes.
• Older Than They Look:
  • As reincarnators, Leon and Marie. Leon was in his mid twenties when he died, and Marie in her forties, and they each reincarnated about a decade before attending the academy. It's worse with Marie due to her underdeveloped body.
  • Yumeria, Kyle's mother, due to being an elf.
• Old Man Marrying a Child: Gender inverted, many lower level noble men are forced to marry older noble women before their twenties either by their step-mother's demands or if they can't find a wife by the time they graduate from the capital's academy. Leon was almost married to a woman in her 50's.
• Old-School Chivalry: This is shown to be part of the value structure of Holfort, generally followed by Leon's friends Daniel and Raymond, but especially his tea ceremony Master. Leon notes how the concept has been contaminated by the Lady Land aspects of society.
• Old Soldier:
  • Duke Redgrave was a renowned adventurer in his youth, and is known for being ruthless.
  • The Black Knight Vandal is a grizzled war veteran who earned a reputation as The Dreaded and a One-Man Army.
  • Marquess Frampton uses this as an excuse for his traitorous ambitions, that he held up the Kingdom so it rightfully belongs to him.
• Once a Season: It's a tradition to have a Big Damn Heroes moment to save a woman, usually Damsel in Distress, in each volume.
• One-Federation Limit: Averted. While the most important countries follow this, there are the United Kingdom of Repard, Queen Mylene's home country, and the Holy Kingdom of Rachelle, Repard and Holfort's rival nation that tends to attack the two.
• One-Man Army: The Black Knight can tear through airships crewed by hundreds. On foot, he even cuts a gory path through several of the Kingdom's mechs, albeit assisted by two Ancient Artifacts.
• One-Winged Angel: According to what's known about the second game's plot, Albergue Sara Rault becomes this as the Final Boss, fusing with Alzer's Sacred Tree after something happens to his daughter Louise. Instead, after going If I Can't Have You… on Lelia over Serge, Emile does this in his place.
• Only One Name: Often used to distinguish nobles, who tend to have three names, from commoners with one. This is an element taken from Japanese history, where commoners didn't have family names until the country industrialized.
• Organic Technology: Certain relics left over from the ancient war between Old Humanity and the New Humans are like this. They seem to be sapient, and drive the normally calm Luxion into a rage.
• Origins Episode: The seventh volume has one of these for the A.I. Ideal, fighting a Hopeless War in the ancient past.
• Out-of-Context Eavesdropping: Yumeria overhearing Marie calling Leon big bro, since nobody else knows they're past-life siblings, causing a Sustained Misunderstanding that Leon's father had an affair with Marie's mother.
