History Characters / KoishiKomeijisHeartThrobbingAdventure

* TheWomanBehindTheMan: Everything that happened around the series is part of the Moon's plan to get reunited with the Earth, with the Lunarians [[spoiler]] and Koakuma [[/spoiler]] doing most of the heavy work around it.

** [[FusionDance Koishi Yakumo]] tries to lampshade this trope to stop Flandre from destroying the barrier, saying that she’ll be killed in the Outside World and she’s being manipulated by the Watatsukis. Flandre is too broken to listen and only complains that Remilia never scolded her...and breaks the barrier anyway.

* NightmareFace: For a millisecond, she pulls off the ''mother'' of all [[SlasherSmile Slasher Smiles]] when she sees her hat torn apart by Flandre. And this is where the video warns you that shit is gonna get real from now on.

* DyingAsYourself: Before delivering a suicidal attack with Kaiju!Marisa, Kaiju!Reimu tearfully admits that she loved living in Gensokyo, resolving incidents with Marisa.
* KilledOffForReal: She and Kaiju!Marisa deliver a suicidal attack on Yorihime, killing the Lunarian but losing their lives in the process.

* KilledOffForReal: By a Vijoka piloted by Seiran.

* LackOfEmpathy: Doesn't even care when she's told her sister was killed.

* BreakTheHaughty: She doesn't lose her grin when [[spoiler:Kaiju!Reimu]] breaks her sword, nor does she when [[spoiler:Kaiju!Marisa]] appears. She does and starts panicking when she gets caught off guard with her substitute weapon being too heavy and too slow to react to her opponent's SuicideAttack.

* NobleTopEnforcer: Downplayed, but she's less psychopathic than her older sister and questions whether all the destruction brought on by the Lunarians was really necessary for the Moonlight Defense Ceremony.

* BadassDecay: Despite being one of the most powerful characters, she wasn't able to realize the ensuing chaos in the Outside World and the Lunarians' BatmanGambit. She's killed by Reisen II and assimilated by Koishi, though she gains control of her body after seeing Reimu on the verge of death and tries to kill Yorihime, the one who hurt Reimu, with a stick. She fails and is forced to watch as Gensokyo is destroyed thanks to her own obliviousness.

* AndThenJohnWasAZombie

* PleaseWakeUp: After seeing Meiling with her neck torn after Koishi’s rampage.

* WhatHappenedToTheMouse: It’s unknown what happens to her after Gensokyo is destroyed. She probably turned into a Kaiju Monster and was killed off-screen.

* WhatHappenedToTheMouse: It’s unknown what happens to her after Gensokyo is destroyed. She probably succumbed to the madness, turned into a Kaiju Monster and was killed off-screen.

* TheBadGuyWins: By episode 19, she eventually has Patchouli all to herself.

* BigBadWannabe: She's one of the bigger threats menacing Gensokyo, but she's still a pawn driven mad by the real villains.

* WhatHappenedToTheMouse: Before Gensokyo is destroyed, she's last seen invading the village with her [=UFOs=] and her youkai army. It’s unknown what happens to her after the Hakurei barrier is destroyed. She's last seen as a Kaiju monster, implying her invasion was stopped by the Watatsukis (not to mention Byakuren was not being herself all along).

* KilledOffForReal: Reisen II kills Yukari by detonating a bomb implanted inside Ran's stomach, then emptying her rifle ammo on her, then by detonating another bomb implanted inside Chen's stomach.

%%zce* OffWithHisHead: How Sunny died.
* ThirdPersonPerson: Star, when she's fighting Cirno.

* AdaptationalVillainy: It's safe to say the canon Toyohime would never have concocted such an elaborate evil plan.

* AdaptationalBadass: Unlike canon, in this fan-video series she is an efficient assassin. She fails to completely exterminate [[spoiler:Yukari]] only because she doesn't know that [[spoiler:Koishi]] can do the thing she does.

* MyMasterRightOrWrong: She possibly has this mentality to both Watatsuki siblings because they liberated her from her eternal punishment.

* LoveMakesYouEvil: All she wants is to be reunited with her lover again, disregarding all the deaths and manipulations it costs.

** The Yukari-Koishi amalgamate tries to lampshade this trope to stop Flandre from destroying the barrier, saying that she’ll be killed in the Outside World and she’s being manipulated by the Watatsukis. Flandre is too broken to listen and only complains that Remilia never scolded her...and breaks the barrier anyway.

* AdapationalBadass: Much stronger than she is in the canon games, thanks to the Lunarians giving her the power to absorb the powers of Gensokyo's dead.

* CloudCuckoolander: When she's not murderously crazy, she's rather ditzy.

* LastOfTheirKind: Satori and Koishi are the last satoris in existence. [[spoiler: Except that's not the case, there are two others that control the bodies of the Watatsuki sisters.]]

* DrivenToMadness: Is driven mad by the moon's effects.
** Or not. Her battle with Mamizou implies that she's just taking advantage of Byakuren's revolution to go wild.

* TheManBehindTheMan: To Koakuma and Reisen II. She masterminded the plan they were carrying out.

* EvenEvilHasStandards: Downplayed, but she questions whether all the destruction brought on by the Lunarians was really necessary for the Moonlight Defense Ceremony.

* CloudCuckoolander

* MoralityPet: For Koakuma.

Byakuren's ally and the avatar of the Buddhist god Bishamonten. Unlike the rest of Byakuren's allies, she resists the moon's influence that has been driving most of Gensokyo’s inhabitants into madness. She opposes Byakuren's revolution alongside Nazrin and the two are killed in response.

[[folder:Koakuma ]]
!! Koakuma
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/koakktha.png]]
-->'''Debuted in:''' ''Embodiment of Scarlet Devil''

Patchouli’s assistant who works as a librarian and a character from Embodiment of Scarlet Devil. She’s meek, shy and prone to tears. Or at least, that’s what she wants everyone to believe.

* TheBadGuyWins: By episode 19, she eventually has Patchouli all to herself.
* BitchInSheepsClothing: Koakuma poses as Patchouli's shy and meek assistant. In reality, she's a homicidal psychopath who doesn't give a shit about anyone but herself and Patchouli, manipulating everyone (including Patchouli) in order to bring her plan into fruition.
* ClingyJealousGirl: She's obsessed with Patchouli, to the point of seeing the ''whole population of Gensokyo'' as potential rivals.
* CuteAndPsycho: When not pretending to be a ShrinkingViolet, she HatesEveryoneEqually but Patchouli.
* DevilInPlainSight: Koakuma is completely beneath anyone's suspicion in the Scarlet Devil Mansion (sans Flandre), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi and Patchy.
* IHaveYouNowMyPretty: She abducts Patchouli before the Hakurei Barrier and Gensokyo are destroyed, having been promised by the Watatsukis that they would spare her.
* MurderTheHypotenuse: She helped orchestrating the massacre of the Gensokyo inhabitants to have Patchouli all for herself.
* LackOfEmpathy: When Patchouli calls her out on her actions, Koakuma says that she wanted everyone in Gensokyo dead and only spared Patchouli because she loved her. She also expresses no concern for all the lives she ruined, seeing them as annoyances who meddled into her relationship with Patchouli.
-->''"Lady Patchouli, I only care about you. I don't care about anyone else. Whatever happens to them, I can say from the bottom of my heart that I truly don't care. These people that I don't even like, all they do is take away your time. I've hated it my entire life. I'm not wrong, am I?"''
* LoveMakesYouCrazy: Her ranting to Patchouli amounts to this in Episode 19. She claims that everything she did, including manipulating Flandre into destroying the Hakurei Barrier, was all for the sake of destroying everyone in Gensokyo so there'd be nobody left to take Patchouli from her.
* MurderTheHypotenuse: She loves Patchouli so much, that she’s willing to destroy all population of Gensokyo just so they won’t have her.
* PowerCopying: Koakuma apparently has the ability to steal powers from the dead, implied by her use of a 'miracle' after Sanae's death. This ends up being confirmed after using Sunny, Luna, Mystia, Youmu, Cirno and Iku's own powers to fight Reimu.
** She also uses Suika’s power over density to give Patchouli a haircut.
* SuccubiAndIncubi: Aside from her being a succubus and disturbing possessiveness over Patchouli, after she abducts Patchouli during the destruction of Gensokyo, she proceeds to rape her.
* UnwittingPawn: To the Watatsukis, since the Lunarians are exploiting her MadLove towards Patchouli as a means to complete the Human Instrumentality Project. They even consider her expendable.
* WalkingSpoiler: Given how heavily she's connected to the events that transpire.
* {{Yandere}}: For Patchouli. She allied with the Lunarians in order to destroy Gensokyo and everyone in it so that she could have Patchouli for herself.

[[folder:Koishi Yakumo]]
!!Koishi Yakumo
After Yukari is killed by Reisen II, her body is assimilated by Koishi, forming a single being, Koishi Yakumo. Koishi is the dominant personality and thanks to the two sharing a body, Koishi has her heart restored. The two eventually separate by Episode 19.

-----
* IHatePastMe: After regaining her heart, Koishi says this about her old subconscious self. To the point she's ashamed of going back to the Scarlet Devil Mansion after the ruckus she caused in the first episode.

[[caption-width-right:350:Moon's humanoid form]]

-->''"Everyone's eyes are closed. Am I the only one with them open?"''

Before the universe was created, the Moon was a humanoid girl. She was once completely alone due to being the only sentient creature with open eyes, but then she had met the Earth, another humanoid, and the two fell in love. The two consummated their relationship, resulting in the birth of all sapient life. Unfortunately, their offspring (the satoris) ended up tainting the Earth, leading them to be separated. The plot of the series is the Lunarians trying to purify the Earth so she could be with him again.

* AncientAstronauts: It's unknown where the Moon came from, just that she fell from the sky long ago.
* GenkiGirl What she was when she met Earth. After the Earth was corrupted, however...
* GreaterScopeVillain: Of the whole series. The Lunarians have varying motives among them, but all involve waking her up and reuniting her with her lover.

* LoveMakesYouEvil: All she wants is to be reunited with her lover again, disregarding all the deaths and manipulations it costs.

-->''"We most certainly....we definitely....were destined to meet."''

The Moon's lover, who also took on a humanoid form. He became tainted with impurity by his offspring, the satoris. He was forced to close his eye and enter a deep slumber as a result, which causes him and the Moon to become separated. The Lunarians' motivation for causing the plot of the series was cleansing him of his impurities so that he and the Moon could reunite.

[[folder: Main Characters]]

* BlueAndOrangeMorality: Calling Koishi outright evil is a stretch, but she's definitely not playing by anyone else's sense of morality and due to her heart being closed, she's just doing things as she pleases. She apparently gets better after assimilating Yukari's head.

!! Reimu Hakurei
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/img_20220122_164508.jpg]]

-->'''Debuted in:''' ''Subterranean Animism''

The elder of the Komeiji sisters. She is the one who took care of Koishi while being on Earth. She has a third eye that can read people's heart, which makes her and the rest of her species despised by others. She is reclusive and rarely participates in any activity that take place on the surface Gensokyo.

* BewareTheMindReader: All satori with opened third eyes are capable of this, but Satori Komeiji is particularly an expert in digging her target's deepest psyche.
* BigSisterInstinct: She cares for Koishi like a sister, blood relation be damned. Her reason for agreeing in helping the Lunarians is partially because she wants people to stop ostracizing her and her sister.
* BrutalHonesty: She reads Koakuma's heart and exposes her as a demon harlot who has malicious intentions and is definitely up to no good. Thanks to Satori's infamous reputation, no one in Scarlet Devil Mansion is willing to accept her words, and she gets chased away violently.
* CombatTentacles: All satori creatures have this.
* CurbstompBattle: She gets this from Remilia. In Satori's defense, it is a 1 vs 3 battle.[[note]]Satori vs Koakuma, Patchouli, and Remilia[[/note]]
* MercyKill: Beheads Rin Kaenbyou because she wants to spare her beloved pet from the Lunarians's cruelty.
* MyGodWhatHaveIDone: Seemingly regrets assisting Watatsuki sisters in preparing the Moonlight Descent Ceremony. She is even ready to sabotage the plan, unfortunately she's stopped by Toyohime who destroyed her host body and brought her back to the Moon by force.
* NotAfraidOfYouAnymore: Defied. She is completely afraid of Toyohime, even the latter's mere echoing voice is enough to make her shudder in fear. Though Satori grows some spine and is willing to stand up to Toyohime, she still cannot get rid of the sense of dread whenever Toyohime is present.
* PowerCopying: By digging her opponent's deepest memories and fears, she can copy various spells her opponent have seen before. She can even easily copy Marisa's Master Spark without the use of mini-hakero.
* ToughLove: How she educates Koishi; Satori does not hesitate to use physical punishment to discipline Koshi, as long as it is warranted and not causing any lasting injury.

!! Koishi Yakumo

!! The Earth

%%zce* CompanionCube: Her hat.

* WellIntentionedExtremist: She claims herself to be one. She acted as an ambassador for the Moon and enforced world peace, abolishing all forms of suffering, including war and violence, on Earth. This had the side effect of bringing those concepts to Gensokyo, as anything that ceases to exist in the Outside World goes there. All of this was for the sake of purifying the Earth so he and his lover, the Moon, could be reunited.

* CuteAndPsycho
* DevilInPlainSight / VillainWithGoodPublicity: Koakuma is completely beneath anyone's suspicion in the Scarlet Devil Mansion (sans Flandre), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi and Patchy.
* GreaterScopeVillain: Of the series as a whole, she's one of the main antagonists working behind the scenes.
** Or so she believes, since the Lunarians are exploiting her MadLove towards Patchouli as a means to complete the Human Instrumentality Project. They even consider her an expendable UnwittingPawn.

* UnwittingPawn: To the Watatsukis.

* HorribleJudgeOfCharacter: Satori warns her that Koakuma is not the ShrinkingViolet she believes her to be and is actually an AxCrazy {{Yandere}}. Patchouli doesn't believe her and blasts Satori from the mansion. After all, [[WhatAnIdiot how could she believe in the words of a mind reader]]?

* GetAHoldOfYourselfMan: Was cut short of pulling Flandres eye out/finishing her off by Satori slapping her, though less of a case of being brought back to her senses and more like her blindly obeying her beloved sister.

** In Episode 19, she makes an offhanded comment about how she's sorry that the cattle that had to die, but it was worth it for the sake of a delicious dinner. Earlier, all of Gensokyo had to die for the sake of the Lunarians's Human Instrumentality Project and Yukari notices that Koishi is implying the same thing.
