Video Game / Rabi-Ribi

Erina is just a normal, everyday rabbit. She loves her owner Rumi and her life on the peaceful Rabi Rabi Island. But one day, she wakes up in a strange place. What's more, besides her bunny ears and tail, she's become human! Now, with a help of her trusty Piko Hammer and a cheerful fairy named Ribbon, Erina must learn the cause of her transformation, while evading the bunny-obsessed members of the UPRPRC!

Rabi-Ribi is a Metroidvania game developed by CreSpirit and published by SekaiProject. Featuring adorable pixel art and an Improbably Female Cast, the game has you explore colorful levels and lets you fight enemies either up close and personal with Erina's Piko Hammer or at a distance using Ribbon's magic. The bosses, meanwhile, throw frantic Bullet Hell patterns at you and can often be brutally challenging.

Over the course of its history, the game has gained a number of DLC and supplementary material:

• Is the Order a DLC? acts as an expansion to the main game, concluding the story by adding two post-game chapters with 3 new bosses, along with a few items and other miscellaneous additions.
• Before Next Adventure, which adds new costumes, achievements, and cutscenes, along with 4 gruelingly tough Special Bosses and a mode where you can play as Cocoa.
• Cicini's Halloween, a free Halloween-themed DLC that adds a new region to the Floating Graveyard, alongside a corresponding boss fight.
• An Original Soundtrack DLC which provides exactly that, along with a second Orchestra Arrangement version. There's also a DLC to give Erina and Ribbon orchestra costumes and the option to change the in-game music to the orchestra version.
• A digital artbook which has development notes, sketches and art of the characters, and a character customizer. It also has a number of unused features that were cut or scrapped from the main game, including experimental difficulties, cut encounters, and 4 extra playable characters in the Boss Rush.^note Rita, Cicini, Syaro, and a standard UPRPRPC minion.

The game was released for PC on January 28, 2016 and is available on Steam, and was ported to to PlayStation 4 and PS Vita to follow in October of 2017. A Nintendo Switch port including most of the DLC^note The Halloween Update and the Is The Order a DLC? update are included, with plans to add the Before Next Adventure DLC was released on October 17, 2019.

Rabi-Ribi has also made a crossover apperance in the Rhythm Game Dynamix, with several tracks from the former appearing in the latter.^note It should be noted that 3R2, one of the composers on the soundtrack team, also makes tracks for a number of music games.

On February 2023, CreSpirit announced TEVI, a Spiritual Successor that follows the same gameplay style of Rabi-Ribi. It released in November of 2023.

On 2024, to celebrate the game's 8th anniversary, CreSpirit announced a Platinum Edition for the Playstation 4 and Switch versions, which includes all the DLC released for the game. A separate DLC will be sold separately for those who already own the game. In addition, a sequel, which will incorporate elements from a separate game called Love Bunny, was announced.

Rabi-Ribi provides examples of:

• Ability Required to Proceed: Sometimes you need to have a certain ability (for example, Wall Jump) in order to get to other areas of the game. That said, you don't exactly need the actual item... Subverted in a 0% run, as there are multiple assists added in (extra springs, suddenly-breakable walls, etc.) to allow players with literally nothing but Ribbon, a few amulets, and maybe a cake or two to go all the way to the end of the game.
• Achievement Mockery: There's an achievement for trying to turn the difficulty below Casual, the easiest available difficulty. There's also one for falling into a lava pit right after Cicini warns you not to. And the achievement for a run where you don't unlock any attacks is "So...Erina, do you expect to win with cuteness?" and features a picture of Erina sleeping.
• Action Girl: Erina and Ribbon, as well as all of the bosses. It comes with the all-female cast.
• All for Nothing: It turns out that gathering spellcasters to power the Stone Stele was completely pointless, as Noah had already completely drained it, and she was the one sending you to the Warp Destination.
• All the Worlds Are a Stage: The first "post-game" area is the Hall of Memory, where you run through a series of rooms modeled after other areas throughout the game.
• Alone with the Psycho: You have to fight Miru (possessed by Noah) in a Room Full of Crazy in an empty hospital in another world after she knocks out Ribbon.
• And Your Reward Is Clothes: Erina gains two new costumes to change into after defeating Noah and the Halloween boss.
• Anti-Frustration Features: The game has a lot of them to balance out its high level of difficulty.
  • Most of the "Dodge Master" achievements require taking no damage...except for five particularly long bosses, in which case depending on the achievement you are allowed to take up to three hits.
  • For players who have not been trained to have superhuman reflexes from a career of playing Bullet Hell games, the dev have done a lot help them stay in the fight and muscle themselves through the story.
    • First of all, there is the casual mode.
    • Also, regardless of difficulty, all boss rooms autosaves before entering, saving you the run in case you fail.
    • And if you really insist on completing the game on a certain difficulty level (normal or below only, see Mercy Mode below) despite not having the superhuman skills to finish the hellish boss fights, you may choose to get a set of free damage reduction buffs for the fight from your third fail on the same boss/area onward, the free buff will become stronger if you fail another three tries on that same boss/area, and so on. Note, however, that the game will start reducing how strong the buffs can get if you make it past certain points.
  • The post-game areas do not have any save point at all. As a compensation, the game auto save more frequently in there.
  • The combo timer stops counting down during certain boss attacks where it would be incredibly hard, if not impossible, to hit them, only decreasing if the player gets hit.
  • Many of the longer boss fights will have the boss start taking increased damage if the game detects that you're struggling to deal damage (eg. if they successfully complete a full attack cycle, something that usually takes a while). This usually persists for the rest of the fight (or the end of the phase, for bosses with multiple stages).
  • The True Final Boss of the Is The Order a DLC? expansion provides an autosave between each of the three phases that places the player outside the battle, with a healing point and a room with enemies to build boost on nearby. Entering the battle from these autosaves makes the boss skip to the phase the player last reached.
  • If you're doing a low-percent run, some of the longer boss fights that would normally need more firepower will change to slightly altered versions with various handicaps. Examples include Rumi going from six health bars to effectively one, and Irisu losing many of her buffs and gaining Cursed for most of the fight.
• Armor-Piercing Attack: The Bunny Memories ignores all defense-altering buffs and invulnerability (except if the target has outright disappeared from the screen) but does a variable amount of damage depending on who you're using it on. The Rainbow Egg's boost effect also damages bosses through invulnerability, although it's harder to notice.
• Auto-Revive: The Bunny Clover enables Erina to automatically use a healing item with reduced effect when she reaches 0 HP, provided she actually has one. The Survival badge also lets you survive a lethal attack with 1 HP (albeit with Healing Rod no longer healing you until you can get back above 1 HP another way.)
• Auto-Save: The game makes auto-saves from time to time, in a separate save slot from your standard save files.
• Beef Gate: The game doesn't always throw hard barriers to encountering certain bosses early such as ability-requiring areas; sometimes it will instead attempt to discourage you by having enemies in a given area be too powerful to safely get hit by unless you return with more HP and damage reduction upgrades. Braving these tough-for-your-stats enemies is necessary to unlocking some of the Sequence Breaking achievements.
• Big Bad Ensemble: The game has two unrelated Big Bads.
  • Noah, who's responsible for sending Erina to the other world and turning her human. She's doing this with the intention of eventually replacing her.
  • The True Final Boss, Irisu, who founded the UPRPRC to find another bunny like her.
• Boring, but Practical: The Sunny Beam isn't as flashy as other projectiles, and doesn't hit for a whole lot of damage, but being a continuous beam makes it a good weapon while you're dodging projectiles since you can just hold down the fire button and keep hitting your opponent as long as you're facing them. This also makes it good for building up your Boost and Combo meters, since it gets in a ton of hits. The charge attack also has a decent shotgun-like spread that guarantees you hit whatever is in front of you, unlike other forward-firing charge attacks which require actual aiming, making quick charges a good way to add to your DPS. The Boost Attack, on the other hand, is anything but boring.
• Boss Bonanza: Chapter 5's only enemies are an unusually hard boss who disables your projectiles followed by an even harder boss with 3 forms.
• Boss-Only Level: Chapter 5 only consists of a short dungeon with no enemies in it, the empty hospital from the prologue, no less, that's designed to build tension up to an encounter with two plot-critical bosses, Miru and Noah.
• Boss Rush:
  • One of the unlockable game modes, which is Exactly What It Says on the Tin, although many bosses have lowered stats and changes to their fight to better fit into the mode. In addition, it has several variants that are unlocked gradually as you progress in the main game:
    • The normal Boss Rush has you consecutively fight every main story boss save for the Final Boss.^{In order}Tutorial Cocoa, Ribbon, Tutorial Ashuri, Green Kotri, Rita (with her Shadow variant attacks), Cicini, Syaro, Chocolate, Saya, Vanilla, Pandora (with her Shadow variant attacks), Cocoa, Blue Kotri, Nieve, Seana, Nixie, Aruarune, Ashuri, Red Kotri, Lilith (without her air battle), Miru (with Ribbon and no gradual defense drop)
    • Another Boss Rush consists of the Final Boss and all of the postgame story bosses after.^{In order}Miru (with the same conditions as the Boss Rush), Noah (all 3 phases in order), Miriam, Rumi, and Irisu (without her initial debuff spam, Damage Reduction, and endurance phase)
    • True Boss Rush is a combination of both the Boss Rush and Another Boss Rush, having you fight every mandatory boss in the game consecutively.
    • Erina Boss Rush, which includes all bosses not already battled, such as the initial DLC bosses and the postgame SP bosses. ^{In order}Keke Bunny, Poor Cat Cocoa, Delicious Food Ribbon, Lust for Research Ashuri, Halloween Chocolate/Vanilla, Pillar Saya, Lilli and Pixie, Erina the Forgotten Maiden (without her endurance phase)
    • BNA Boss Rush has you fight all of the SP bosses added in the DLC, along with a final challenge at the end. ^{In order}Sorceress of the Tundra Rita, Glitched Syaro Returns (without the entire first phase), Miru Syndrome (starting from the point when you get Ribbon back, but with no defense drop), Irisu in Wonderland (without her debuff spam/endurance phase), and a heavily buffed Illusion Alius
  • The Hall of Memory not only mimics the environments of the areas you've previously journeyed through but each area contains a degraded version of each major boss you've fought. You can just run past these bosses if you want to get to the end quickly to unlock a teleporter and access a fight with Miriam.
  • The Forgotten Cave II is a gauntlet solely consisting of consecutive battles against weaker (but debuff-spamming) copies of every boss you've fought so far (save Noah and Miriam), and unlike the Hall of Memory you must defeat each one to advance. This culminates in an encounter with Illusion Alius IV before a boss battle with Rumi.
• Bragging Rights Reward: Defeating all 4 Superbosses of the Before Next Adventure DLC on one file with an S rank or higher will grant an extra donut slot and unlock "Super Quick Charge Ribbon" for that file, causing Ribbon's magic to fully charge almost instantaneously. The latter is obviously Purposely Overpowered, but considering you've already beaten the Elite Four of the SP bosses with that high of a rank, you really won't have much to use either for.
• Brainwashed and Crazy: An interesting phenomenon that creates bunnies falling from the sky causes anyone affected by it become obsessed with bunnies and want to capture one. Naturally, this ends up being the cause of quite a few boss fights.
• Broken Bridge: Although the game is usually pretty lenient with sequence breaking, some areas of the game can be absolutely inaccessible until the plot tells you to go here.
• Brutal Bonus Level:
  • All four post-game areas are this in their own ways:
    • Hall of Memory in Chapter 6 is a mishmash of existing areas with illusions of past bosses that are treated as regular enemies but are no less deadly. All enemies can easily tear off three-digit damage with each hit. At the end you fight a brainwashed Miriam, who boasts a boatload of health, fierce attacks, and can buff herself up to unholy levels based on what badges you have equipped. If you make the mistake of having your usual badge setup equipped, the fight can go on way longer.
    • Forgotten Cave II, also in Chapter 6, is a Boss Rush with your only reliefs being that there are Auto-Save checkpoints and each defeated boss restores a large chunk of your health. Oh, and many of the bosses's attacks here slap you with Skill Ban if they connect, preventing Erina from using any of her attacks for several seconds. At the end, you fight a brainwashed Rumi, who boasts six lifebars.
    • System Interior II, in Chapter 7, is a Platform Hell area with laser turrets and spikes galore. Fortunately, there are heal springs in a few spots. A little Sequence Breaking allows you to get here early.
    • The Floating Library is The Very Definitely Final Dungeon, accessible only in Chapter 8 after recruiting almost all town members. It features Spikes of Doom all over the place which require some very precise platforming to get around, and culminates with a Marathon Boss of a True Final Boss, Irisu.
  • There's also the DLC areas, all of which expect the degree of skill and dedication needed for the postgame:
    • The Halloween DLC adds a new section of the Floating Graveyard loaded with unconventional platforming and puzzles, culminating in a very difficult Dual Boss fight with Chocolate and Vanilla and Cicini.
    • "Ravine II/Windy Ravine", the first area of the Is The Order a DLC? expansion, is laced with spikes, ridiculously damaging enemies, spiked balls, crusher enemies that release bullets when they hit the ground, and wind currents that will impede your horizontal movement. The area has two gruellingly difficult bosses, Pillar Saya halfway through the area, and Lilli & Pixie at the end, with an Escape Sequence immediately after the latter boss.
    • Hall of Memory II/Hall of Deep Memories, the second area of the Is The Order a DLC? expansion. After a short gauntlet of spikes, blocks that can only be broken by enemies, and Quick Man lasers, the area splits into four regions that must all be cleared to proceed. Each region has its own unique obstacle (plus lots of spikes) and a midboss at the end. In addition to there being very few enemies, the Bunny Amulet is taken away at the start of the area, only able to be retrieved just before the new True Final Boss.
• Buffy Speak: Despite Syaro calling the item-detecting device she hands to Erina a cell phone, the game refers to it as a "Strange Box".
• Bullet Hell: In a platform game, no less.
• Cast from Hit Points: The Bunny Memories drains some of Erina's HP to deal massive damage to enemies in the center of the screen. This prevents its use in Dodge Master achievements.
• Cast from Money:
  • The Rainbow charge shot consumes some EN when fired. If fired without enough EN, it'll do no damage. Collecting more Easter Eggs will increase the cost of firing it, but also significantly boost its damage.
  • Downplayed with the Cashback badge's hidden effect, which fires at the boss while expending a single EN.
  • Inverted with Miriam, who can hijack Ribbon and discharge your EN at you as projectiles using the Soul Heart.
• Charged Attack: All of Ribbon's magic attacks can be charged up. Certain upgrades decrease the charging time, or allow her to double-charge attacks.
• Clarke's Third Law: All of Cicini and Syaro's science-based abilities are oddly indistinguishable from the magic in Erina's world, to the point that science-based devices can be charged with EN.
• Clothing Damage: Some of the CGs of the bosses shown after you defeat them reveal this. Originally it was only Ashuri, but the recent "Before Next Adventure" DLC added a few more. It's quite subtle, however.
• Cloud Cuckoo Land: In Plurkwood, you fight a slew of bizarre enemies that are cartoonish even for the game's standards, most notably headless dog shaped cooked meat that launches exploding bones at you. The boss is a bunny girl who leads a pack of them but sometimes eats them. She tries to convince Erina to let her eat Ribbon but attacks when Erina refuses. She disappointedly says she guesses she can't eat Erina because she's a bunny too. After the fight, she wonders why Erina didn't eat her, apparently having forgotten why she didn't eat Erina. That's just the tip of the bizarre iceberg. As it turns out, the entire stage is Product Placement for the social media service Plurk.
• Collision Damage: Present on most enemies. The Pure Love badge stops collision damage from all female bosses (read: every single named one), and the Fire Orb lets Erina inflict collision damage back onto enemies. Some of the cheaper bosses will exploit collision damage by leaping into you right before you touch the ground after you jump over one of their attacks.
• Combos: The game has a rank-based combo meter that increases as you get more and more hits in (increased if you chain together unique attacks), and decreases if you go too long without hitting anything or get hurt. A higher combo ranking grant you a proportional damage boost for as long as you can keep the combo going. The P Hairpin, obtained by doing a side quest in Plurkwood, amplifies this damage boost by 25-35%.
• The Computer Is a Cheating Bastard: Illusion Alius fights exclusively by using your moves. Too bad you'll be getting most of those moves long after she uses them on you. She also uses charged projectiles directly after boost attacks which is impossible because Ribbon stops charging in preparation for the boost attack.
  • Some attacks hit you no matter what unless you do the exact thing you're supposed to, even if it doesn't make sense. One example is Noah's giant energy balls that seem to be perfectly guided toward you yet you can dodge them by doing a small jump at the last moment so they dart off into the sky.
• Counter-Attack: The 99 Reflect (reflects all attacks that do over 99 damage) and 300 Revenge (inflicts the Instant Death debuff, which turns the next attack that hits its recipient into a One-Hit Kill, after an attack that does over 300 damage) buffs act as this. Illusion Alius has a more standard counter that triggers if you melee her when she has "..." over her head, causing her to strike back for massive damage in retaliation.
• Crash-Into Hello: That's how Erina and Ribbon first met.
• Critical Status Buff:
  • The Fairy Flute, obtained by beating the first bonus chapter of the DLC, summons Lilli and Pixie to protect you when your health gets low, healing you and dealing very high DPS to enemies for a while. It has a lengthy cooldown, however.
  • The Crisis Boost badge gives you a substantial 25% damage buff when below 20% HP, and the orange Carrot Shooter that Ribbon can get deals damage scaling with how little HP you have left.
  • Turned against you with all bosses in Hell difficulty or higher, where they'll gain buffs to their attack, defense, and speed once you bring them down to about 10% health.
• Cyberspace: System Interior.
• Damage-Sponge Boss: Initially subverted. All bosses generally have enough HP that if you aren't trying to actively burst them down, they'll last just long enough to go through most of their attack patterns before being defeated; easier difficulties will let you kill them faster and vice versa, but none of them get particularly long if you're not playing too defensively. However, in the endgame and DLC encounters, the bosses have a lot of moves, and their HP is extremely high to match, turning almost every endgame encounter into a Marathon Boss lasting upwards of 10 minutes. Not helping is that several of the endgame bosses either have invincibility phases, gimmicks that make you unable to damage them for a certain time, or multiple health bars.
• Death of a Thousand Cuts: The Sunny Beam hits for very low damage, but since it fires continuously, it hits more often than any other weapon, so those 1's add up pretty quickly.
• Defeat Means Friendship: How most major characters are recruited.
• Developer's Foresight: The game will sometimes acknowledge if you've been Sequence Breaking and hand out the appropriate achievements or even outright assist you by adding springboards or allowing certain walls to be broken. Additionally, if you manage to get to Ribbon without the Piko Hammer (only possible with the secret techniques), the game will simply drain her life automatically so that you have a damage dealer.
• Developer's Room: CreSpirit HQ, which is full of developers' avatars. You can visit it only during your third journey to the human world.
• Die, Chair, Die!: It's possible to destroy Cicini's chair and computer during her boss fight by dropping a Cocoa Bomb on it. You even get an achievement for doing so.
• Distracted by the Sexy: One of the achievement, "Because this game is non-linear..." is for intentionally doing this, by getting to Lilith as your first town recruit and beating her first phase. As she's on the other side of your first few marked town recruits, and there's another town recruit in the middle, you really have to go the extra mile to get to her first, especially on a new game. The achievement image have her and Erina with hearts above them.
• Double Jump: One of the abilities Erina can learn. She can also get two extra jumps by picking up the Wind Blessing in the Is The Order a DLC? expansion, but those only work during boss fights.
• Dramatic Disappearing Display:
  • The entire HUD disappears whenever Noah talks, potentially resulting in fake difficulty.
  • The last phase of the Halloween bosses removes the entire HUD as well.
  • Happens twice more during Erina's third and fourth phase.
• Dynamic Difficulty: Bosses will increase in level and therefore difficulty the more powerup items you collect. The "Alternative" type of level scaling has them increase in level based on story chapter instead, allowing you to simply rack up a bunch of upgrades and roll over a good chunk of the bosses before you've even completed the first chapter, at the expense of a consistently brutal endgame where you will want every last upgrade.
• Earth All Along: The Warp Destination looks awfully a lot like modern day Earth. In fact, the entire game takes place on Earth.
• Easter Egg: There's 50 of them scattered across the island (plus 10 more in each DLC). Gaining 5 of them grants Rainbow Egg Shooter and collecting more of them increase its power.
  Every game need an easter egg
• Easier Than Easy: Casual difficulty, below Novice. Then there's Bunny Heaven, which makes all of the bosses level 1 and Erina move faster, and Erina 200%, which causes Erina to start the game with every item and an absurd number of powerups.
• Easy Levels, Hard Bosses: The levels themselves are mostly simple platforming with some enemies thrown in, but the bosses can and will easily destroy you with their Touhou-esque Bullet Hell patterns. Subverted in the post-game; the levels get fiendishly hard at that point.
• Elaborate Underground Base: Exotic Laboratory and UPRPRC HQ.
• Empty Room Psych:
  • There is a room in upper Starting Forest known affectionately as the Lonely Girl Room, since the only thing it contains is a single nameless NPC whose sole dialogue is an assurance that there's nothing in the room. There's another one in the Golden Pyramid, but this time she's lying.
  • When you come to face Miru again, you find her room empty. Next room also has nothing in it. However, as soon as you try to go back...
• Energy Weapon: The yellow magic, which continuously fires a piercing laser while it charges. Even though it deals very low damage, it's great for building your combo meter, but not so much for maintaining it.
• Escape Sequence: There's one in the Is The Order a DLC? expansion. After defeating Lilli & Pixie in the upper Ravine, Erina must escape the area within a time limit based on the difficulty, scaling from literally nonexistent in Casual to as little as 4 and a half minutes in Bunny Extinction.
• Everything Trying to Kill You: Apart from crazy UPRPRC bunny-lovers, there are living mushrooms and flowers, cute little ducks, dogs, fish, other fairies, nerds (in human world), strange round and fluffy cat... things.
• Evil Knockoff: The Illusion Allius series of bosses serve as this for Erina and Ribbon. There are also illusory versions of certain bosses like Rita and Pandora with alternate movesets due to instability from regular use of the Stone Stele. Eventually they attack Rabi Rabi town, and can be found littered all throughout the Hall of Memory.
• Expy:
  • Cocoa and Irisu greatly resemble Cocoa and Syaro from Is the Order a Rabbit?, although this Cocoa takes more after Order Syaro's personality.
  • Ashuri is an expy of Marisa Kirisame, while Erina visually resembles Reisen.
  • Nixie and Nieve resemble the Ice Climbers.
  • There's a pair of catgirl sisters named Vanilla and Chocolate who have white and brown hair, respectively, a nod to Vanilla and Chocola from Nekopara who are also siblings with white and brown hair.
  • This game and Kirby 64: The Crystal Shards, both have a pink-haired ribbon-wearing sidekick fairy co-star named Ribbon & both games have a boss that's just a rotating formation of gems launching projectiles that has an inanimate magic gem you need. The Artbook confirms that Ribbon's resemblance to the Ribbon from Kirby 64 is intentional.
  • A lot of the enemies also bear a resemblance to Kirby enemies. One particular enemy found in the Golden Pyramid is almost identical to the Mumbies from the Kirby games, albeit colored differently and with different behavior.
  • Another enemy has the same purpose and design as the Thwomp from Super Mario Bros., albeit with rabbit ears and a cat smile.
• Fake Ultimate Mook: The dark area of Starting Forest has massive versions of some of the easiest minor enemies. They have a lot of health but the size increase makes them even easier than the standard versions because it negates their usual advantage which was that they were tiny enough to easily roll/leap past your attacks.
• Final-Exam Boss: Miriam, whose attacks encompass every item the player has collected. She also throws out illusions of nearly every character in the game.
  • Noah and her last fight as Erina the Forgotten Maiden use attacks from every other boss in the game.
• Four Is Death: Taking a hit while under the effect of the Instant Death debuff deals a flat 4444 damage to the player, killing them in one hit if they don't have a Last Chance Hit Point.^note On New Game+ runs, the debuff will increase in damage to match the player's increased stats, as a maxed player will likely have more than 4444 HP after a loop or two..
• Fun with Acronyms: The UPRPRC stands for "Usagi PeRoPeRo Club".^note "Usagi" is Japanese for rabbit, and "peropero" is Japanese onomatopoeia for licking; thus, the entire acronym roughly means "Bunny Licking Club"
• Gameplay and Story Integration:
  • Save Points and Warp Points are an in-universe fixture. Various NPCs report not needing to sleep if they save regularly, but there's also a fear that it shortens your lifespan, while they find it easier to go to and from Rabi Rabi Town via warp points than just walking.
  • Defeating enemies awards EN and heals Erina, which is implied to be her harvesting magical energy from them, which is why the otakus at the Warp Destination do neither upon being defeated.
• Glass Cannon:
  • Kotri's red form is considered a late-game encounter, but she has health as if she was an early game boss. However, she makes up for it by using attacks you generally can't react to (forcing you to memorize), incredibly high damage output, and the ability to stick the Burn debuff on you.
  • All of the Illusion Alius bosses have very low HP, but can end you with just a few hammer strikes.
  • The Attack Trade badge turns Erina into one, making her deal 25% more damage while taking 50% more damage.
  • Bringing yourself to 1 HP with the Survival badge and using both Crisis Boost and the Carrot Launcher will turn you into a One-Hit-Point Wonder that will die to so much as a stiff breeze, but will also deal so much damage that it's possibly to outright defeat easier bosses with a single extended combo. This strategy is often used for those trying to do Dodge Master achievements.
• Greater-Scope Villain: Cicini's father, who's been trying to find a way to teleport to Rabi Rabi Island, threatening the peace that Noah sacrificed herself to achieve. Fortunately, Cicini's curiosity means that she now has the device he was going to use to get there, and eventually figures out how to seal the island forever. Somewhat subverted, as his motivations are stated to be scientific curiosity rather than outright malice - it's just that the island being discovered could lead to a chain of disastrous consequences.
• Guide Dang It!:
  • Most achievements in general are very hard to get without using a special guide, and most of them need to be done over numerous save files.
  • At some parts, you have no quest markers, so figuring out how to progress can be confusing.
  • The hidden techniques, which you are required to do in a Minimalist Run due to not having mobility upgrades. There is a place that teaches you how to do them in game, but it is very easy to overlook and you can't get back to it after a certain point.
  • The Hammer Roll allows Erina to roll over spikes unharmed. This is explained nowhere in the game, and is necessary to get past an obstacle in one DLC area.
  • Activating a left/right path on a BNA special boss isn't very clearly shown to begin with, but activating the Extreme Path (using a Cocoa Bomb during the difficulty selection) is only hinted at by a very vague achievement description. Activating Extreme+ mode (using a Cocoa Bomb right as the right path selection ends), on the other hand, isn't explained anywhere in the game.
  • Erina's second and third hammer strikes deal greatly increased damage to targets behind her. This isn't explained anywhere in-game, but proves incredibly helpful when defeating bosses quickly.
• Halloween Episode: The "Cicini's Halloween!" DLC. It unlocks new sections of the Floating Graveyard, and has a side plot in which Cicini and Syaro introduce the inhabitants of Rabi-Rabi Island to the concept of Halloween, with Lilith helping out in making costumes. It culminates in a Dual Boss fight with Chocolate and Vanilla in mummy costumes.
• Harder Than Hard:
  • Hell difficulty mode, followed by Bunny Extinction mode if you clear Hell mode, where the bosses can have downright unfair attack patterns and levels up around a whopping 150. The Artbook DLC takes it a step further with Unknown mode and Impossible mode, where it's quite possible to see a Level 190 Irisu on the first loop. There's also an "Extra" mode Boss-Only Level with Irisu that is technically yet another step above Impossible, but (without hacking) is restricted to this fight alone, and is as brutal as you might expect.
  • There's also the "Bunny Hell" mode, which gives all of the bosses ridiculously high levels and insane speed. It can be stacked with the aforementioned Bunny Extinction mode for an even harder challenge.
• Healing Shiv: The charged green magic fires homing projectiles that heal you a little bit if they hit an enemy.
• Hidden Elf Village: Rabi Rabi Island was on Earth All Along, but Noah's sacrifice magically sealed the island away from the outside world. When everyone finds out, they decide to stay hidden rather than have the entire world swoop in to investigate them.
• Hitbox Dissonance: Because Rabi-Ribi was designed with bullet hell elements in mind, Erina's hitbox is actually much smaller than her sprite, different from the usual fare for 2D Platformers and Action games. It can be viewed either through a hidden technique or just shortly after a boss fight starts (in the later versions). To balance it out and make things look fair, the game designs the rest of the game's hitboxes with both sides in mind:
  • The aura/glow around many small bullets are included in the hitbox. Notable example is the pellets that sprout from the swaying stems attack.
  • Most bullets that look larger have their hitboxes smaller than the edge of the sprite would suggest. Notable example is Syaro's falling crystals attack; on certain difficulties, going through the middle of 2 of these perfectly placed beside each other is the only way to clear that pattern without damage. Another example is Irisu's screen-filling explosions, where you can stand completely inside them without taking damage as long as you're at the very edge.
  • Hitboxes of enemies are usually a bit larger than their sprite suggests. While this makes landing combos easier without sacrificing difficulty, it also balances it out due to Erina's visual sprite actually hitting the enemy visual sprite to trigger Collision Damage.
  • Despite the game's balance, there are still some projectiles that are quite non-intuitive:
    • Lilith has an attack where lightning shoots down from the sides of the screen and thin-but-long bullets form from them and move towards the center. The hitboxes of these thin bullets extend slightly way past its tail.
    • One of the final bosses of the main game is a long, huge flying creature, and it has an attack which swoops down and immediately flies up towards your location. However, the wings have absolutely no hitbox, meaning you can just walk sideways and completely dodge it. Justified in that the attack is so fast that it would probably be undodgeable otherwise. This does also mean, however, that hitting its wings don't do damage.
    • "Lightning-like" laser attacks' hitboxes immediately form entirely even before the the entire lightning comes down. This means that if you happen to be just in range of where the laser would strike, as soon as the visual forms at the top of the ceiling, Erina can get hit even before it hits the ground. This is most evident when it's the fatal attack, as the screen freezes when Erina gets KO'd and you can see the lightning not even anywhere close to the middle of its path.
• Hold the Line: Any boss with the Endurance debuff (such as the rematch with Seana and Irisu's final phase) can't be damaged, but very slowly lose health over the course of the fight, turning it into a survival match.
  • Technically, every boss is programmed to take gradual damage over time when not attacking, provided that you lack both the Piko Hammer and Ribbon. Normally, this can only ever happen with the tutorial fights against Cocoa or Ribbon (as the game forces you to take Ribbon after that point), but through certain exploits, it's possible to progress further without any weapons, leading to self-proclaimed "pacifist" runs.
• Idiosyncratic Difficulty Levels: Beyond Casual, Easy, Normal and Hard, there's Hell (unlocked after beating the game on Hard) and the aptly-named Bunny Extinction Mode, unlocked after clearing the post-game on Hell difficulty. The Artbook also includes experimental Unknown and Impossible difficulties.
• Immune to Flinching: The Super Armor buff prevents stun. There's also Quick Reflex, which severely cuts down on the amount of stun time. All bosses will gain Quick Reflex if you try stunlocking them for too long, before getting Super Armor if they still fail to break out of your attack after that.
• Improbably Female Cast: To the extreme. The only male characters that appear in the game at all are from the other world and Plurkwood.
• Interface Spoiler: The maps only show rooms you've entered. Looking at the Warp Destination map early on can spoil the fact that the hospital you were in at the beginning of the game is there.
• Invulnerable Attack:
  • Using a Bunny Amulet charge grants instant and brief invincibility along with stunning and slightly damaging all on-screen enemies. It serves as one of your most reliable ways to avoid attacks.
  • The Super Carrot also renders Erina invincible during its effects, but it's a Charged Attack that takes longer to charge the more it's used in succession (while also increasing its damage). The timing is additionally delayed unlike the Amulet which gives the invincibility frames right away, making it Difficult, but Awesome to use.
  • Downplayed with the Bunny Memories. Erina can still take damage while using it, but her HP won't go below 1. It does, however, make her immune to certain attacks like shockwaves and some lasers, although it's inconsistent.
• Kill Sat: The Sunny Beam's boost attack visually resembles this, calling down delayed beams of light to smite enemies from above. Several enemies and bosses have similar-looking attacks.
• Lag Cancel: The Frame Cancel badge allows Erina to cancel out of the long animation of her fifth Hammer Combo attack by pressing down. Cocoa has this ability by default, due to her basic attack being an infinite auto-combo.
• Last Chance Hit Point: The Survival badge lets Erina survive an otherwise-fatal attack with 1 HP. Being at 1 HP will also disable the healing effects of Ribbon's green magic, requiring Erina to use an item or defeat an enemy to get back above 1 HP. Certain bosses also have this ability, becoming immune to damage for a while after reaching 1 HP so they can launch a final attack or trigger a phase transition.
• Lethal Joke Character: The UPRPRC member can't attack at all. But as a compensation, she has extremely high HP, 9 charges of Bunny Amulet (Erina only has 4), and the Bunny Amulet deals higher damage and gives her temporary Bunny Lover (cut damage in half if the opponent is bunny), HP Regen, and Healing.
• Lethal Lava Land: The Volcanic Caverns. Downplayed, in that the lava is strictly cosmetic, unless you're fighting Kotri's "red" form in which case she has an attack that causes lava waves to rise up and damage you if you touch them.
• Let's You and Him Fight: The Bunny Phenomenon, which causes everyone in the area to become obsessed with bunnies like the UPRPRC and allows boss fights with characters who would never fight Erina otherwise.
• Little Bit Beastly: Erina, Cocoa, Vanilla, Chocolate, Kotri, Nieve, and Nixie. Not Irisu, though, as she's just a normal human wearing bunny ears. Although it turns out she is a bunny after all.
• Lucky Seven: There's a badge of the same name^note Some enemies can also apply it to themselves as a buff that causes every seventh attack to deal either 7% or 77% bonus damage. It also has some unlisted secondary effects: against bosses, your first and seventh hit deal at least 77 damage, while dealing 77, 777, and 7777 hits causes the respective attacks to deal 777, 7777, and 77777 minimum damage, the last of which is required to get an achievement.
• Magic Missile Storm: Most bosses attack this way, and most of Ribbon's boost attacks also qualify. Cicini and Syaro, on the other hand, replace these with actual missiles.
• Magikarp Power: The Rainbow shot type starts out weak, but grows stronger as Erina collects more eggs, eventually becoming by far the most damaging single attack in the game.
• Marathon Boss: Miru, Noah, most of the post-game bosses, and most of the DLC bosses, especially in New Game Plus. All of them can generally take upwards of ten minutes for even an experienced player.
• Marshmallow Hell: Rumi subjects Erina to this the moment she sees her human form.
• Mercy Invincibility: The game is very generous with its immune frames after taking damage, and several items and badges can be used to increase it further, on top of the several Invulnerable Attacks you have. Turned on its head with the Mortality debuff, which strips the target of all immunity frames.
• Mercy Mode: On Normal and below, if you get enough Game Overs in a row the game will give you a "Halo Buff" that raises your defense and amulet charge rate and restores your health when you attack.
• Minimalist Run: invoked There are achievements for completing the game without the Piko Hammer (your main mode of attack) and without getting any items. The game will notably change its level design and boss battles if it sees you don't have certain items, or are outright doing a low or zero percent run.
• Mirror Boss: Illusion Alius (AKA Dark Erina and Ribbon), the most Recurring Boss. She forgoes fancy Bullet Hell pattern in favor of single charged attacks, boost attacks, and bum rushing you with her hammer. Just like what you usually do against bosses.
• Money Spider: Almost everything you can defeat will drop EN, the game's currency. However, EN is implied to be used as much more than just currency; some characters say that you have to pay them so that they can charge up enough magic to cast something.
• Ms. Fanservice: Most of the cast.
• Murder Is the Best Solution: A common reason major characters try to attack Erina on sight. If they aren't impulse-attacking, then they're probably Brainwashed and Crazy.
• Musicalis Interruptus: Occurs after Erina's boss fight, as an event interrupts the credits with their accompanying music.
• Never the Selves Shall Meet: Not part of the plot, but letting Erina the Forgotten Maiden meet Noah in her final phase makes them stare at each other and gives you an achievement called "Time Paradox".
• New Game Plus: An NPC will allow you to start new loops once you clear the postgame. You retain all your items, gain a boost in all your stats, and greatly increased damage bonuses from combo ranks. As a compensation, the enemies and bosses become significantly stronger, overall making the game more difficult.
• Nintendo Hard: The game is quite tolerable on Casual, but even on Easy the game is no slouch. Difficult bosses with Bullet Hell that has to be dodged with gravity in the way, bosses getting harder based on player progression, a number of Brutal Bonus Levels, achievements that require a strong degree of skill to unlock, a paid DLC pack that requires beating the already-hard post-game first...this game is not for the easily-discouraged. Plus, there are many ways to make the game even harder than on a non-New Game Plus Hell run.
• No-Damage Run: Enforced by the Dodge Master Achievement for each boss from Chapter 1-8, where you have to defeat them without taking any damage whatsoever. A few of the later bosses will give you multiple hits before being disqualified, but since they tend to be Marathon Bosses...
• No Hero Discount:
  • Double Subverted: Miriam is fully willing to give Erina her wares for free, but Erina insists on paying like everyone else.
  • Justified in the case of your allies and the buffs they give you; the currency is energy that they need to make whatever they're offering to you. Cocoa is the only exception, and she's also justified on account of being in poverty.
• No-Sell:
  • All of the enemies inside the System Interior, including the boss, nullify melee attacks, so you'll have to rely on Ribbon's magic and Erina's carrot attacks to do damage.
  • Most enemies in The Hall of Deep Memories nullify all attacks except for the magic type that matches their color.
• Non-Indicative Name: The game plays a little fast and loose with the definition of "Post-Game", which may as well be called "Second Half of the Game". There's three more chapters with four dungeons across them to go (after the first five chapters, effectively four since Chapter 5 consists only of a short enemy-less dungeon and two boss fights) and you can't initiate a New Game Plus or use the Is the Order a DLC? content until after beating the True Final Boss in Chapter 8.
• Noob Cave: The aptly-named Starting Forest.
• Numerical Hard: Boss level only influences how much damage they inflict and how much HP they have. A level 50 boss looks no different than the same boss on the same difficulty level at level 150.
• Otaku: The UPRPRC are creepily obsessed with rabbits to the point of annoying everyone else on the island. The Warp Destination has some more traditional otaku who stalk and harass Erina thinking she's a cosplay model.
• One-Time Dungeon: Most areas can be accessed again any time after you enter them, but you can only go to the street in the real world and the hospital in the same area two times each, each time when the plot makes you go there. The only way to visit them again after is to defeat Irisu to reset event progress.
• Optional Boss: Keke Bunny is notable for being the only town member who is not required to enter the Floating Library. She is, however, required for 100% completion and several achievements.
• Patchwork Map: Rabi Rabi Island has an unusually wide variety of environments for a small island in the middle of the ocean. The picture of the island shown on the warp screen makes this even more obvious.
• Permanently Missable Content: Subverted; some of the Easter Egg items only appear in the other world, and after you clear the main game, you're locked out of it until you unlock the boss refights by clearing the post-game.
  • Certain items in the upper parts of the Ravine are only available during the Escape Sequence. Fortunately, the DLC chapters can be reset by fighting the True Final Boss again.
• Platform Hell: The majority of System Interior II and the Floating Library comprises a series of very hard platforming sections that require mastery of every single one of your mobility skills.
• Poor Communication Kills: Half of the boss fights happen because of this, and its routinely lampshaded. The other half is caused by Noah's brainwashing wave.
• Portal Network: You can use Warp Stones to travel across the land.
• Post-End Game Content: Not counting the "post-game" as an actual post-game, the game does offer things to do after defeating the post-game final boss: 3 incredibly difficult bonus bosses to the point of being unfair, DLC content (that adds up to two new areas and 8 more bonus bosses), all boss encounters being reset, the Erina and Ribbon badges, and finally the ability to access New Game Plus loops. This is also the only time you are able to get the last 5 upgrades for each stat from Miriam.
• Product Placement: A teleporter in the nighttime regions of the Starting Forest takes you to Plurkwood, which features various Plurk mascots as enemies. For beating the boss of the area, you can earn some Rabi-Ribi emoticons if you have a Plurk account.
• Public Domain Soundtrack: Several songs are actually from royalty-free sources, hence why they don't show up on the offical soundtrack. The version 1.8 update replaces these with original songs produced specifically for the game.
• Pyramid Power: The Golden Pyramid, home of Pandora.
• Rank Inflation:
  • The scale for how you're graded on boss performance goes as follows: E, D, C, B, A, S, SS, SSS, MAX. This also determines how big of a damage boost you're getting.
  • The levels of the bosses start getting silly once you get to the post-post-game Superbosses. The Final Boss tops out at level 150 in the main game. The easiest superboss is around level 360. The True Final Boss can hit levels as high as 1000+ on the highest difficulties.^However...This is mostly just for show, as levels affect different bosses' stat scaling in different ways, particularly when it comes to the SP or DLC bosses compared to the base game ones. For example, even with a visible level several times that of the postgame Final Boss Irisu, many of the SP bosses will generally have less than half her health and comparable damage, while the True Final Boss Erina at a 4-digit level will have only slightly more HP (for each of her Multiple Life Bars) and generally lower damage.
• Really 700 Years Old: Pandora is about 1000 years old, despite looking so young.
• Recursive Reality: There's a Rabi-Ribi billboard at the Warp Destination, as well as figures or plushes of Erina and Ribbon in Miru's room at the hospital. Despite this, the otakus there don't recognize Erina or Ribbon.
• Red Herring: Despite being introduced as one of the main antagonists, the UPRPRC aren't involved with the main plot at all. They're not even responsible for the Bunny Phenomenon, though they may be a byproduct of it.
• Robot Maid: A whole bunch of them can be fought in Exotic Laboratory and in System Interior. Also, Syaro pretends to be one of these (but she is a human nonetheless)
• Room Full of Crazy: The arena where you fight the penultimate story boss. It's covered in distorted drawings of bunnies.
• Sad Battle Music: The tracks used for the first and third forms of the Final Boss Noah are noticably somber compared to other boss themes. Said tracks later get reused for a possessed Miriam in Chapter 6 and the True Final Boss Irisu in Chapter 8, respectively.
• Schmuck Bait: The System Interior has an area where Cicini warns you that falling into the glowing red holes will hurt a lot. Falling into the first one shortly afterwards will result in a One-Hit Kill and an achievement; fortunately, there's a Save Point one room back.
• Script Breaking: Going hand in hand with Sequence Breaking, it is possible to trigger Chapter 8 early — even before completing two of the postgame dungeons prior to the library — through a difficult jump in System Interior to System Interior II, before the game requires you to go there and removes an obstacle preventing you from getting there the intended way. After completing this area, the Chapter 8 intro scenes will play out. Downplayed, as you can't enter the library until you've recruited all non-bunny town members, including Noah, Miru, Miriam, and Rumi, all of which are end-chapter bosses, so while you will experience the story out-of-order (and have to fight all unfought bosses significantly overleveled), you won't miss any of it. There's an achievement for breaking the sequence in this manner.
  • Exaggerated with the Order DLC, which adds a secret room in speedrun mode that lets you skip from Chapter 1 all the way to Chapter 9 instantly. Beating the game this way is required for one of the secret achievements, Bunny Hop.
• Sequence Breaking: Not only possible, but actually encouraged, as the game doesn't really do much to enforce a specific order of progression, and actually gives many achievements for doing things out of conventional order as well as a myriad of ways to do so.
• Songs in the Key of Panic:
  • The rather cheery "Bunny Panic!!!" plays in a few miniboss encounters where UPRPRC members attack you in waves, and gets faster with each successive wave cleared out.
  • The theme of Miru, the first boss in Chapter 5, a very dark and dreary piano-focused track, speeds up and raises in pitch to an eerie minor as the boss's health gets down to critical levels.
  • COUNTDOWN!, which plays while escaping the Windy Ravine in the Is The Order a DLC? expansion speeds up as time runs out, getting to a ridiculous pace nearing the end.
• Short Range Guy, Long Range Guy: While Erina prefers use her Piko Hammer come up close and bash enemies with it, Ribbon specializes at shooting long ranged magic projectiles.
• Shout-Out:
  • The Piko Hammer has almost the same name and appearance as the Piko Piko Hammer from Sonic the Hedgehog.
  • The "boss" of System Interior II is a pretty clear homage to the Gravitron from VVVVVV. The dialogue before it begins even mentions "WWWWWW".
  • The Is The Order a DLC? name is a clear reference to another bunny-loving franchise, Is the Order a Rabbit?. There's also the achievement for beating Keke Bunny and talking to her in town, called "Is the Order This Rabbit?!"
  • The Special Boss version of Miru is titled Miru Syndrome, a clear reference to Irisu Syndrome!. The fight is just as creepy as the game.
• Situational Sword: The Rainbow Egg's boost effect gives you the normally enemy-exclusive Bunny Lover buff, which halves incoming damage if the enemy is a bunny...which doesn't do you many favors when Erina is explicitly stated to be the only (known) bunny on the island. It only has an effect on Keke Bunny, Noah, Irisu, and Erina the Forgotten Maiden.
• Spikes of Doom: A common type of trap during the game. Hitting them deals major damage to Erina (even more than most bosses are capable of dishing out and effectively a One-Hit Kill on higher difficulties), and enemies can be lured into them to wipe them out. You actually get an achievement for clearing the entire game without touching one. No easy task, as the final Brutal Bonus Level is loaded with them. You can eventually find a Spike Barrier item that lowers the damage they deal to you, but that usually just lowers the damage from "instant killed" to "mortally wounded".
• Spiritual Successor: To Bunny Must Die. Both are goofy anime-style indie Metroidvanias about a Playboy Bunny inflicted with some kind of transformative curse that they're never actually cured of by the end of the game (with Rabi-Ribi the Playboy Bunny look is the curse, while in Bunny Must Die the protagonist was already one) with some Bullet Hell aspects. Rabi-Ribi was even initially set to have a "Bunny Must Die" difficulty until it was renamed to "Bunny Extinction."
• Spread Shot:
  • Charging the Sunny Beam fires a strong spread shot. Double-charging it makes the spread larger and wider.
  • The Healing Staff fires a four-way spread.
  • The Explode Shot fires a three-way spread in both directions.
  • The Chaos Rod fires a fifteen-way spread that covers a 90-degree angle.
• Stone Wall: The DEF Trade badge enforces this by giving you 20% damage reduction at the cost of 15% of your damage output.
• Stripperiffic: Quite a few of the girls, but Pandora, Kotri, Seana, and Lilith especially come to mind. Kotri, Seana, and Lilith at least justify it by being a dancer, a mermaid, and a succubus, respectively. Pandora has no excuse. Rita actually points out the Chainmail Bikini trope, talking about how less clothing equals more protection as if it were common knowledge.
• Superboss: Special/SP Bosses, unlocked after Chapter 8. They're immensely souped-up versions of existing bosses which don't progress the game nor provide anything of tangible value, and can usually surpass even the True Final Bosses in difficulty.
  • The base game has SP Cocoa, Ribbon, and Ashuri, and Before Next Adventure adds SP Irisu, Rita, Syaro, and Miru. ^note Pillar Saya and Erina the Forgotten Maiden in the Order DLC fit the bill on the surface, but are not optional and must be defeated to progress the story Good luck trying to beat any of them.
  • An extra point regarding the BNA bosses is that they have four levels of difficulty adjustment on their own, determined by a screen-dividing HUD that appears during a dodge-friendly phase early in the fight. They are triggered by: staying on the left side of the divide (Normal, or "Left-Side"), staying on the right (Hard, or "Right-Side"), pissing the boss off with a Cocoa Bomb during the selection (Extreme), or staying on the right and using a Cocoa Bomb while the HUD is fading away (Extreme+)^*(which sounds like an invokedUrban Legend of Zelda, but no, this is an intended interaction not listed anywhere; SP Miru must be defeated on this difficulty for an achievement). While their attack patterns don't change, level spikes and extra buffs are layered on with each difficulty.
• Super Move Portrait Attack: Each major boss gets at least one. Erina also gets one when she uses her Bunny Amulet.
  • Using the Bunny Memories also gives one for Erina and Erina!Noah.
• Super Not-Drowning Skills: Erina and Ribbon have no problems with breathing underwater. Although, they tend to move very slow if you don't have the Water Orb obtained after defeating Nieve.
• Talk to Everyone: Defied; not only is it not required to talk to any unnamed NPCs to complete the game — NPCs with no name given give you nothing for talking to them — or even to get full item and town completion (in fact, you only need to use the "Talk" action on a total of two NPCs to complete the main game), but there's even an achievement for talking to enough nameless NPCs.
  NPC on Rabi Rabi Beach: "You don't have to talk to everyone here. Why do you feel like you need to?"
• Tastes Like Purple: Each of the stat-boosting potions have a flavor listed in their description: the red health potion tastes like strawberries, the yellow pack potion (which boosts the number of badges you can equip at one time) tastes like lemon. The purple attack boosting potion is simply described as tasting like purple.
• Too Awesome to Use: Downplayed. The Gold Carrot found in a secret area at the top of the Icy Summit, is the only food item in the game that will fully restore your HP when consumed. Only one of them exists, but it'll respawn at its original location if you eat it, meaning that you'll need to run all the way back to its resting place if you ate it and want another one, but otherwise are not withheld from getting more of them.
• Too Kinky to Torture: Ribbon hints that the UPRPRC members actually enjoy getting beat up by Erina.
• Turns Red: In general, most bosses will bust out new and more dangerous attacks the closer they are to defeat. This is also one of the features of Hell difficulty and up; when near death, bosses gain buffs to attack, defense, and speed.
  • Several of the bosses featured in the postgame will heal themselves if you try to eat a food item during their fight. Played straight by SP Cocoa, Ribbon, Ashuri, and Saya, who will gain massive temporary buffs if you try to heal.
• Underground Level: A lot of them: Forgotten Cave, Spectral Cave, Golden Pyramid, Volcanic Caverns, Natural Aquarium, and Hall of Memory.
• Unexpected Shmup Level:
  • After defeating Lilith for the first time, she challenges Erina to take her on in the sky instead. With the help of Ribbon and her two friends, she is able to fly, turning the game into a Horizontal Scrolling Shooter.
  • The boss battle with Rumi puts a similar shooter section after each boss phase.
• Variable Mix:
  • The music slows down when Erina is under the "Speed Down" status. It also slows down and additionally decreases in pitch whenever she goes underwater until you get the Water Orb.
  • The first Chapter 5 boss's theme gets faster and faster the more you wear their health down.
  • The Halloween bosses BGM, Mischievous Masquerade gets faster once they reach their final phase and Cicini joins the fray.
  • The music-altering effects are all missing in the Switch port, likely due to a bug.
• Video Game Cruelty Potential:
  • The cocoa bombs you buy from Cocoa can be used to do meaningless damage to residents of Rabi Rabi Town and temporarily destroy buildings. If you do it to Cocoa, she takes a billion damage and stays in her taking cover animation and you get an achievement.
  • You can find some of the developers of the game and murder them. You even get an achievement for it. Their irrelevant responses bring to question whether or not they really die though.
  • There's an achievement for beating the game without saving Ribbon's friends.
  • Also, there's an achievement for beating the final boss of the Is The Order A DLC? expansion without picking the Bunny Amulet back up.
• Video Game Caring Potential: The description of the Art Book DLC says that a portion of all profits will be donated to Cocoa. If you buy it, the game tells you the money you spent bought her a carrot.
• Wall Jump: One of the abilities Erina can learn. You're limited to how many consecutive wall jumps you can make, but you can buy upgrades to increase the jump limit. You can also perform it without the Wall Jump item using a hidden tech.
• Warp Whistle: There are various Warp Points around the map that allow Erina to warp to any other Warp Point she's been to. These are acknowledged in-universe, as the residents of Rabi-Ribi Town find it easier to warp to and from the town rather than leave on foot, and at one point Erina manages to activate one without having been to any other Warp Point, which just causes it to shunt her off to the other closest Warp Point underground.
• Weird Currency: EN, implied to be magical energy harvested from defeated enemies. Aside from using it to buy items at Miriam's store, it can also be given to spellcasters so they can cast buffs on Erina.
• Wins by Doing Absolutely Nothing:
  • If you make it to Cocoa and Ribbon with no mobility upgrades or hammer by Sequence Breaking, the fight will start as usual...except their HP will deplete to nothing in a few seconds. A no-hammer run would be impossible otherwise.
  • The playable UPRPRC Girl has no means of attack, so in her Boss Rush, all bosses will slowly deplete their HP, leaving the Girl to have to just dodge everything until she wins.
• World of Badass: All but one of the named characters are proficient magic users of some kind who can tank barrages of projectiles and beatings from a mallet. Two of the most common enemy types are humans using magic and fairies firing magic all over the place. Even most of the nonhostile NPCs are casually hanging out around crazy magicians and wild animals.
• Wraparound Background: In the shmup section when chasing & fighting Lilith, the background loops pretty often & there's a very visible line where it happens.
• Yuri Genre: While this game is not advertised as such, it has many of the tropes of the genre. There's a lot of lesbian subtext between many of the game's characters, especially towards Erina. And in some cases it's pretty blatant.
