The Cute Rabbit Who Transformed Into a Girl

Erina is a bunny that, for unknown reasons, has turned into a human.

  • Action Girl: She uses a huge mallet, can throw kicks and shoot energy balls, and generally kicks the ass of everyone who challenges her with the help of her trusty Fairy Companion.
  • Ambidextrous Sprite: Erina's stocking wanders from her right leg to the left and vice versa.
  • Baleful Polymorph: A milder example, but Erina is eager to go back to being a regular rabbit.
  • Boobs of Steel: While her bust is nowhere near as impressive as some characters, it's certainly more notable than Ribbon's, and Erina is the melee fighter of her team.
  • Close-Range Combatant: Her hammer and carrot attacks (aside from Hammer Wave) are short-ranged.
  • Drop the Hammer: Piko Hammer, one of Erina's weapons.
  • Even the Girls Want Her: Where to begin? Rumi immediately adores Erina's new human form and begins to show a more romantic attraction to her, Lilith comes on to her the moment she sees her, Miru talks about how she likes Erina's gifts more than anyone else's, Irisu has a very obvious crush on her, and let's not even get into the entire UPRPRC. By the time you see the true ending it's pretty heavily implied that she and Irisu become a couple.
  • Expy: Her design is effectively Reisen from the Touhou Project with purple eyes and a Playboy Bunny outfit.
  • Fashionable Asymmetry: A single thigh sock on her right leg.
  • Generation Xerox: Her and Noah's true form look uncannily alike. This may be by intent, since Noah's responsible for her transformation, and was planning on replacing her. In the ending, Erina ends up dressing and wearing her hair like Noah without even realizing it.
  • Happily Adopted: Since there's seemingly no way for her to return to normal, Rumi takes her in as a little sister by the normal ending.
  • Insists on Paying: Miriam offers her her items for free, but Erina insists on paying full price, no discount.
  • Last of Her Kind: Bunnies are practically extinct on Rabi-Ribi Island, leaving Erina as seemingly the only bunny on the island. It turns out there's actually two. Three if Erina convinces Keke Bunny to come to the village.
  • Leotard of Power: She wears a Playboy Bunny ensemble, but nobody knows why except for "It stands for rabbits, so it makes sense, right?"
  • Little Bit Beastly: As a rabbit turned human(oid), she has rabbit ears and a tail.
  • Magically Inept Fighter: Lacks the capability to produce Bullet Hell like everyone else, but makes up for it with her close-range prowess.
  • Mistaken Identity: Most people who can't detect the polymorph magic on her just think that she's a UPRPRC member, even as she's under attack by actual UPRPRC members.
  • Official Couple: All but outright stated to be one with Irisu by the end of the game.
  • Playboy Bunny: Erina sports the uniform. Why? She'd also like to know.

The Lively Fairy Seeking Freedom

A fairy who Erina literally runs into. She joins Erina to search for her friends and gives her access to ranged magic.

  • Beam Spam: Both as an ally and an enemy.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, humorously named "Delicious Food Ribbon".
  • Crash-Into Hello: When she bumps into Erina, she mistakes the rabbit girl as a monster and attacks Erina.
  • Defeat Means Playable: She has to be fought by Erina, and then afterwards she becomes the game's primary source of ranged damage.
  • Embarrassing Nickname: Doesn't like being called "Ribi" by anyone other than her two fairy friends. Much to Ribbon's chagrin, Cicini starts using this nickname due to her association with the fairies.
  • Fairy Companion: She is a fairy and Erina's most loyal friend.
  • Fairy Sexy: Notably, her two friends are more conservatively dressed.
  • Genre Savvy: Ribbon sheds this trait quite a bit before boss fights later on, commenting on the room's design and even mentioning that something's going to happen because of a change in music.
  • Happily Adopted: Becomes part of Rumi's family by the normal ending.
  • Long-Range Fighter: In contrast to Erina's short-range hammer skills, Ribbon uses her magic primarily to hit enemies out of melee range.
  • Pint-Sized Powerhouse: She may be small, but she can nail down attackers from a distance.
  • The Red Mage: Uses offensive and healing magic.
  • Spanner in the Works: Her presence somehow complicates Noah's plans, to the point of her voicing how much she doesn't like her.
  • Straight Man: Plays the role to Erina who does not often grasp human concepts.
  • Stripperific: Her default outfit. She's the skimpiest of her circle of fairy friends, and when Erina asks why she's dressed like that, she dodges the question by asking why Erina is dressed like that.
    • Hilariously, her DLC Halloween costume (which was given to her by Lilith and is meant to be incredibly Stripperific) actually gives her a little more clothing than usual.
  • Third-Person Person: She basicly never says "I", only "Ribbon" when refering to herself.
  • Wins by Doing Absolutely Nothing: It's entirely possible to encounter her before you get the hammer, which you would normally use to fight her. If this happens, her health inexplicably drains during the fight, turning it into an endurance battle.


The Heart of Rabi Rabi

Erina's owner and one of the key figures of Rabi Rabi town.

  • Benevolent Boss: Is Erina's master, and her kindness to Erina clearly shows when they reunite.
  • Big Good: Regarded as the leader of Rabi Rabi, secretly protecting the peace in town.
  • Bonus Boss: Fought as part of the Post-End Game Content.
  • Brainwashed and Crazy: The reason you have to fight her.
  • The Heart: Kind and friendly, especially to Erina, and she helps the heroic duo by deciphering the Stele and assisting in the teleportations done with it.
  • Heroic BSoD: She undergoes a rather amusing case of this in Chapter 8 when she thinks Irisu is doing something lewd with Erina.
  • Idiot Hair: Sports a small one, but she is not really an idiot.
  • Marathon Boss: She has six life bars, with an Unexpected Gameplay Change in between each health bar where you're briefly tackling a shooting-style fight similar to Lilith's second battle. Only the Final Boss and True Final Boss take longer to beat.
  • Marshmallow Hell: Subjects Erina to this the moment she sees her human form.
  • Muggle: Subverted. She can't use magic except when brainwashed, but she is a telepath.
  • My Sister Is Off-Limits!: She takes exception to Irisu when she thinks she's doing something lewd with Erina (who she sees as a little sister by this point).
  • Nice Girl: Most residents comment on how kind she is.
  • Sdrawkcab Name: In Japanese, her name (ルミ) is the reverse of her sister's name, Miru (ミル).
  • Telepathy: She can communicate with people through this.

Rabi Rabi's Only Merchant

The shopkeep of Rabi Rabi town.

  • Adam Smith Hates Your Guts: Double Subverted. She tries to give Erina her items for free since they're friends, but Erina insists on buying them normally because she wants to be treated the same way as everybody else. She settles on giving you a discount, but it doesn't stop her from raising the prices of powerups as they are bought. If you don't have enough to pay for an item, she offers to give the item to you for free, but Erina won't actually let the player take the item without paying.
  • Bonus Boss: Fought as part of the Post-End Game Content.
  • Brick Joke: When Erina sees the Bunny Slippers, Ribbon theorizes that they'll let her walk on air. When Miriam copies them, they let her do exactly that.
  • Ditto Fighter: Miriam's attacks and self-buffs change depending on the items you have. This makes her significantly easier in a 0% run, as most of the time she'll be unable to attack because you don't have the items she'd otherwise draw attacks from. She can also summon Degraded Boss versions of every boss in the game and even hijack control of Ribbon.
  • Final-Exam Boss: Her Super Attack summons illusions of the game's bosses one after the other, ending with Miru. Unfortunately for you, she draws this attack from the Bunny Amulet, the one item you're guaranteed to have.
  • Grand Theft Me: On the receiving end of this in the post-game by Noah.
  • Idiot Hair: Has a noticable one, but much like Rumi, she is not an idiot, just a little naive.
  • Muggle: One of only a few characters that can't use magic. This does not prevent her from becoming a powerful Bonus Boss, though.
  • No Hero Discount: Zig-zagged. She's entirely willing to give Erina her goods for free, but Erina insists on paying like everyone else. She still insists on giving you a discount and will occasionally force Erina to accept an item for free, but the items she forces Erina to take aren't for sale in her shop, so she's still not getting her merchandise for free.
  • Outside-the-Box Tactic: How do you beat a boss who has all your equipment and copies all your badges? Get to her with as little equipment as possible. Failing that, dequip all your badges aside from the few she can't copy (or better yet, equip badges with tradeoffs that lower defense and health.) Also, she can't copy buffs given to you by the townspeople, so shelling out 25k for Miru to give you every buff in the game will let you roll right over her.
  • Shopkeeper: Manages a shop in Rabi Rabi town and sells all kinds of useful items and upgrades to Erina.

The Shy Childhood Friend

A girl on whose lap Erina wakes up following her transformation into a human. She seems to have an affinity with Erina.

NOTE: Many of the tropes regarding Irisu make her one big Walking Spoiler, so be wary.

  • Astonishingly Appropriate Appearance: Unlike every other bunny and bunnygirl cosplayer in the game, she has droopy ears, betraying her introverted nature.
  • Beware the Nice Ones: She's one of the most quiet and adorable people on the island. Her first action in her boss fight is to pepper Erina with some absolutely awful debuffs and lead with a bullet the size of the screen.
  • Big Bad: A separate Big Bad unrelated to the incidents with Noah. She's the leader of the UPRPRC. She's not really evil, though.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "Irisu in Wonderland".
  • Book-Ends: At the beginning of the game, Irisu is tending to a sleeping Erina. At the end, it's Erina who's looking after Irisu after she'd passed out from their fight.
    • She's also the very first character the player sees (not counting Erina) and the last one they fight (in the base game, at least.)
  • Death-or-Glory Attack: Once her health is depleted, she casts Endurance, a buff that restores her health and makes her invulnerable to damage. On the flip side, her hp slowly depletes to zero as she unleashes her final attack, a very complex pattern of bullets.
  • Did They or Didn't They?: In Chapter 8, after Irisu confides in Erina that she created the UPRPRC, Erina happily forgives her and lays down on Irisu's bed, causing Irisu to lose control and pounce on her. Exactly how far they get isn't shown, but it is enough to drive Rumi into a Heroic BSoD and make Irisu deeply regretful of what she'd done (though given how Erina behaves towards Irisu in the ending, she didn't seem to mind).
  • Driven by Envy: She wanted to be Erina's master instead of Rumi. She created the UPRPRC so she could have a bunny of her own. She has green eyes, too.
  • Easily Forgiven: Erina's response to Irisu's confession that she was the one who created the UPRPRC is very nonchalant, and she happily forgives her for it despite all the trouble they've caused.
  • Fairytale Motifs: Word of God is that her original name was Alice, and she has a White Rabbit theme going on. She even rides on a giant floating clock for some of her attacks, and her Special boss version is literally named "Irisu in Wonderland".
  • Four Is Death: She can put a debuff on you that causes any attack that hits you to deal 4,444 damage, more than enough to kill you, considering your HP caps at a little over 1,000 HP.
  • Freakiness Shame: Her crippling loneliness and introversion are suddenly cast in a different light upon learning that her bunny ear "headdress"... isn't. She probably believed she was the only bunny girl in existence, and would've been right if it weren't for Noah kickstarting the plot with Erina's transformation.
  • "Get Back Here!" Boss: She spent most of her time either on the background or floating well above Erina's range.
  • Hidden in Plain Sight: If the UPRPRC had thought to look within their own ranks, they'd have found an actual bunny a lot faster.
  • I Just Want to Have Friends: Most of her actions make a lot of sense upon the reveal that she's a rabbit, as rabbits have been known to die if left alone.
  • Little Bit Beastly: Those rabbit ears aren't just a part of her headdress like everyone thinks. She really is a rabbit.
  • Macross Missile Massacre: One of her final attacks is the game's de-facto example.
  • Not Evil, Just Misunderstood: Irisu has a deep affection for Erina (and bunnies in general). Unfortunately, she's cripplingly shy to the point that she runs away from her whenever she sees her. She also admits to being jealous of Rumi, as she wanted to be Erina's master instead. She formed the UPRPRC so she could have a bunny of her own, and admits that they took things too far.
  • Official Couple: All but outright stated to be one with Erina by the end of the game.
  • One-Hit Kill: If you do at least 300 damage to her with one attack while she has Revenge 300, you'll get a temporary status effect that kills you the instant anything hits you.
  • Rewatch Bonus: Much of what she says when she's tending to the sleeping Erina at the start of the game doesn't make a lot of sense until you've cleared the Post-End Game Content and realize that Irisu is initially mistaking Erina for another UPRPRC member.
  • Red Oni, Blue Oni: Blue introvert to Erina's red.
  • Shout-Out: Bunnygirl? Check. Dangerous introvert? Check. We know another character of that name and description.
  • Shrinking Violet: She constantly makes excuses to distance herself from Erina. Though it's less the fact that she's shy and more the fact that she's afraid Erina will hate her because she created the UPRPRC.
  • Stalker with a Crush: Word of God says she is always behind Erina.
  • Stuff Blowing Up: Her net somehow is able to create a huge explosion that would make Cocoa blush.
  • True Final Boss: Not only the boss of the final chapter, but even getting to her requires beating almost all other bosses. She gets demoted to a Disc Two Final Boss if you have the Is the Order a DLC downloadable content.
  • Unusually Uninteresting Sight: No one really calls to attention the rabbit ears she wears, which is particularly notable since the only other people with rabbit ears are Erina and UPRPRC members and Keke Bunny and Noah. It's revealed later that they're part of her headdress. Or so everyone thinks at first...
  • Villainous Breakdown: Played straight and then subverted. When her health is depleted to almost nothing, she stops firing magic at you and tries to jump at you with a net repeatedly out of frustration (without the explosions). However, soon after that, she regains all of her health and goes into her final survival attack.
  • Walking Spoiler: Most of her secrets remain that until the post-game.

The Poor Cat-Eared Inventor

An impoverished cat found in the Starting Forest and later under it. She initially mistakes Erina for a member of the UPRPRC and attacks her in the confusion.

  • Badass Normal: Despite not having any magical powers, she still proves to be a challenge against Erina and Ribbon thanks to her personal stash of explosives. Not just that, she's one of three bosses to have an SP version!
  • Big Sister Instinct: While they never actually interact in game, it's stated in the art book that she looks after Chocolate and Vanilla. Notably, they both use her inventions in their respective boss fights.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "Poor Cat Cocoa". Considered to be one of the hardest bosses in the entire game due to her ability to bypass Mercy Invincibility paired with her most basic bomb attack being incredibly difficult to dodge.
    • As an Easter Egg added for the 2019 new year, the fight can be made even more challenging if you don't attack her SP version for the whole duration of her first attack. In response, she'll power up into "Poor Cat Cocoa 2019" and gain a slew of new attacks.
  • Cat Girl
  • Expy: Cocoa of Is the Order a Rabbit?, though only by looks and name. Otherwise, she is more similar to Sharo: repelled by (fake) bunnies, cripplingly poor, very diligent and hard worker, just to name a few.
  • Goggles Do Nothing: She wears goggles on her head, presumably to shield her eyes from the explosions, but there is not a single instance in the game where you see her wear it, even during fights where she should naturally most need it.
  • Hammerspace: Her bag can hold an infinite amount of bombs.
  • Hates Being Touched: She has a tail, but she hates people touching it, so she keeps it hidden.
  • Immune to Mind Control: The only member of the cast who can resist the bunny phenomenon.
  • Improbable Weapon User: She uses a pogo stick in lieu of Erina's hammer dive as a playable character.
  • Magically Inept Fighter: She herself has very little in the way of bullet hell. All she has is a small spread shot she can perform in the air. Her bombs, however, more than pick up the slack.
  • No Hero Discount: Justified. She's in poverty, and needs the funds from the bombs she sells you.
  • No-Sell: For reasons unknown, she's immune to the bunny phenomenon.
  • Not Brainwashed: In her second boss fight, the bunny phenomenon takes place and she appears to be brainwashed by it, prompting a boss fight. After the fight she reveals that it had no effect on her and she was just pretending to be brainwashed to create an excuse to try out her new weapons.
  • Perpetual Poverty: Allegedly from constantly needing to upgrade her bombs.
    Thank you for purchasing this artbook.
    Your kindness has provided Cocoa with a carrot.
    Another day, another meal.
  • Promoted to Playable: She's scheduled to become a playable character in a future update.
  • Pyromaniac: Her love for fireworks and explosions is also her source of perpetual poverty, since she spends all her money on material and research.
  • Recurring Boss: She's fought twice: First in Starting Forest as a Warm-Up Boss, then later in the Forgotten Cave with her new weapons.
  • Smart Bomb: Her Cocoa Bombs, which she sells to Erina. Using one inflicts massive damage to all on-screen enemies.
  • Stuff Blowing Up: She attacks exclusively using explosives.
  • Teleportation: Picking up the Sliding Power with Cocoa doesn't give her a slide. Instead, she summons a small bomb that runs along the ground. Doing the slide input again will cause Cocoa to teleport to its location.
  • The Tramp: Despite being poor, she never looks bad and always has provides as a source of explosives for Erina to use in battle.
  • 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 called "NYAAAAN".
  • Wounded Gazelle Gambit: In her second boss fight, she pretends to be under the influence of the bunny phenomenon so that Erina and Ribbon try to snap her out of non-existent brainwashing, giving her the ideal chance to try out her new weapons.
  • Wrench Wench: Being poor, all of her tools are hand-made.

The Sorceress of the Tundra

A magic user found in Azure Snow Land. She attacks Erina after falling under the influence of the bunny phenomenon. She is one of the few characters who can sense Saya easily and she acts as her mentor.

  • And Now for Someone Completely Different: You get to play as her briefly in a side chapter.
  • Barrier Maiden: One of three, along with Ashuri and Pandora, responsible for keeping the barrier around Rabi Rabi Island up.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "The Sorceress of the Tundra, Rita".
  • Brainwashed and Crazy: Why she attacks Erina. Word of God states that they couldn't think of a reason Rita would attack Erina, so they made up the bunny phenomenon as an excuse.
  • Chainmail Bikini: When approached in town, Rita mentions that fewer clothes conveys more protection.
  • Heavy Sleeper: Heavily implied. She mentions sleeping for 12 hours once during the later chapters.
  • An Ice Person: Found in an icy area and fights with ice magic.
  • Leitmotif: "Melting Point." Notable in that she's the only boss this music plays for.
  • Leotard of Power: Wears a blue leotard and sports some very powerful magic attacks.
  • Miko: Wears typical shrine maiden sleeves and seems to have a spiritual advisor role for the town, alongside her powerful magic.
  • Ninja: Partly. She's considered an ice witch, but a lot of her moves are very ninja-like. She throws icicle bullets like kunais, can dive kick, lunging kicks across the screen, and the way she handles her fan weaponry resembles that of various Asian martial arts, among others.
  • Public Domain Soundtrack: Her original boss theme, "Midstream Jam", is actually a royalty-free track available for use in doujin games. It was later replaced with an original track for her, "Melting Point".
  • School Swimsuit: Her costume was more similar to one in her early sketches.

The Girl With No Presence

A girl found on Evernight Peak and a close friend to Rita. She laments her meek presence as she is often ignored by those around her.

  • Blessed with Suck: Her choice to specialize in wind magic is responsible for her weak presence.
    • After being defeated by Erina she attempts to avert this by learning magic that would make her more noticeable, though when she tries it on Erina, it enlarges her. The game's comment is akin to "how is this useful?"
    • It's useless because it immediately expires when Erina goes out of town. Otherwise, it would have actually been useful because the Giant buff grants additional attack and defense in exchange for speed.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, humorously named "Pillar" after what Ribbon mistakes her for in her original encounter.
  • Cannot Spit It Out: It is pretty obvious she loves Rita, but cannot ever admit it. Her shy personality and small presence do not help when people constantly talk over her, causing her to hold back even more. She is positively delighted when Rita offers her to study new magic together.
  • Invisible to Normals: Due to her wind magic. Only a few characters can interact with her on a regular basis, and even then, there's a chance she still gets ignored.

The Other-Worldly Genius

A girl found in the Spectral Caves. Erina encounters her as she is preparing to experiment on Ribbon's friends.

  • Child Prodigy: She first appeared on the island while conducting research with her father.
  • Clarke's Third Law: Cicini insists that her attacks and abilities are purely non-magical technology. Ribbon can't tell the difference.
  • Does Not Like Shoes: To go along with her "shut-in" look. She does wear shoes as part of her Halloween outfit, though.
  • Easily Forgiven: By Ribbon's friends, Lili and Pixi, for capturing them for research. Ribbon even starts to get jealous that they're enjoying spending time with her.
  • Genki Girl: No matter what, she is always full of energy and curiosity for the things around her.
  • I Choose to Stay: Decides to stay behind with Syaro at Rabi Rabi Island and renew the seal, knowing that if she were to ever return home she'd be interrogated about where she'd been.
  • Long-Range Fighter: While Erina and Rita are mostly melee fighter, all her attacks are projectiles.
  • Mad Scientist's Beautiful Daughter: Her scientist father forced her to focus on her studies and research, to the point that she wasn't even allowed to see her childhood (and only) friend Syaro. Cicini eventually steals her father's latest invention out of curiosity and concern, which leads to her and Syaro getting transported to Rabi Rabi Island.
  • Mission Control: She plays this role twice in the game, once to lead Erina and Ribbon to the main system of the Exotic Laboratory to prevent it from going idle, and then again to assist Erina and Ribbon in freeing Syaro from said system.
  • Not Allowed to Grow Up: Claims that Syaro "magically stole all her nutrition" while they were growing up, which is why she looks younger than she is. Whether she's actually serious or just making a joke is not touched on.
  • Older Than They Look: She's around Syaro's age.
  • Panty Shot: A walking one, as the only other things she wears are a lab coat and a shirt underneath.
  • Roboteching: Her signature beam attack and her playable aerial attack does this.
  • The Shut-In: Her labcoat without pants or shoes look gives her the appearance of a young woman who's so obsessed with her research she doesn't particularly care about physical appearances. She stops acting like much of a shut-in once she befriends Erina, but still looks the part.
  • Trapped in Another World: Due to a scientific mishap, she and Syaro wound up transported between worlds to Rabi-Ribi Island. Though as it turns out, she never actually left Earth.
  • Wake-Up Call Boss: Avoiding some of Cicini's attacks is not immediately intuitive. Her somersault beams immediately come to mind. On top of this, she's considerably harder than Rita, the other boss recommended for the early game. This is on top of her computer serving as a small mini boss before you fight Cicini proper. She'd be a much easier boss with better items and a double jump. Unfortunately, Cicini blocks access to said double jump. As such, it's highly advisable to fight her early, despite her difficulty.
  • You Can't Go Home Again: Her research into the island leads her to this conclusion.

The Maid Imitating AI

A girl who became trapped in the System Interior of Cicini's laboratory. She is identified by the system as one of its robot maids and is forced to attack intruders.

  • A.I. Is a Crapshoot: The system identifies her as one of the robot maids and compels her to attack Erina.
  • Big Sister Instinct: Not related but she is very protective of Cicini.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "Glitched Syaro Returns".
  • Boobs of Steel: The most endowed of the cast. She is also invincible to all physical attacks, and the strongest playable character.
  • Brainwashed and Crazy: Less "crazy", but the System Interior mistook her for a real Robot Maid and controls her during her boss battle. She does not seem to remember the fight, either.
  • Energy Weapon: One of her attack lets out a pretty damaging laser beam that recoils her backwards. Her playable self use this as her default attack. It shreds bosses in seconds.
  • Hates Being Touched: After the battle, Erina and Ribbon try to touch her and thus find out she is not like the Robot Maids encountered so far. She immediatly reacts with revulsion and complaints.
  • I Choose to Stay: Decides to stay behind with Cicini at Rabi Rabi Island and renew the seal, knowing that if she were to ever return home she'd be interrogated about where she'd been.
  • Long-Range Fighter: While Erina and Rita are mostly melee fighter, all her attacks are projectiles.
  • Macross Missile Massacre: One of her attacks let out a series of colored missiles of varying speed at your direction. Her playable self can do this as well.
  • Meido: Subverted, she is not a Robot Maid like the rest encountered. She mainly dons the uniform and adresses Cicini as "master" due to their childhood, as it was the only way they could spend time together, and it simply stuck.
  • No-Sell: Like all other enemies in the System Interior, she's immune to melee attacks. This doesn't apply to the illusion of her in the Forgotten Cave II, where she can be damaged with kicking and hammer attacks.
  • Ridiculously Human Robots: Subverted, she dresses like Cicini's robot maids in order to remain close to her after Cicini's father forces her to focus on research.
  • Spell My Name with an "S": "Sharo" on the loading screen.
  • Trapped in Another World: Due to a scientific mishap, she and Cicini wound up transported between worlds to Rabi-Ribi Island. Though as it turns out, she never actually left Earth.
  • You Can't Go Home Again: Like Cicini, she eventually faces the reality that they cannot go back home for the sake of protecting Rabi Rabi Island, but she is alright with that as long as she can be with Cicini.

The Oblivious Underwater Singer

A girl who built a sound studio in the Natural Aquarium to realize her dream of becoming an Idol Singer. Her performances become so rowdy that her audience is forced to defend themselves.

  • Apparently Human Merfolk: Supposedly a mermaid, but looks no different than any other human character.
  • Dreadful Musician: Not in the usual sense. She's actually a very talented singer. The problem is that when she sings Bullet Hell goes flying.
  • Enthralling Siren: Erina is so moved by Seana's second performance that she's inflicted with the Fatigue debuff (which lowers your speed and jump height) for the entire fight.
  • Idol Singer: She dreams of becoming one. She does eventually get to perform for everyone in Rabi Rabi Town, only for all of them to flee once the bullets start flying.
  • Obliviously Evil: She doesn't even realize that her singing is dangerous, and complains when you interrupt her performance.
  • Placebo Effect: Cicini eventually provides her with a new invention that helps Seana with her fear of leaving the water by making her feel like she's still underwater. This "invention" is just a normal innertube that Syaro bought her.
  • Sirens Are Mermaids: She doesn't have any mermaid traits, but she is a singer who lives underwater, who's singing turns out to be deadly.
  • Spell My Name with an "S": Like Kotri, she gets an alternate romanization of her name on the loading screen: Shiina. This also reveals the pronunciation of her name: Seana, rather than "Se-a-na", as you might otherwise assume.
  • Underwater Boss Battle: Her first boss fight is the only one to take place underwater for its entirety. While Erina and Ribbon have Super Not-Drowning Skills, it's not recommended to fight Seana without getting the Water Orb to de-hinder movements. There is an achievement for winning this fight without getting said Orb first, though.
  • Walking Swimsuit Scene: Justified, as she's a mermaid.
  • You Gotta Have Blue Hair: Has teal-coloured hair due to her association with water.

The Older Cat-Eared Sister

The older of the Cat Girl sisters. She runs into Erina while searching for her sister, mistaking her for the UPRPRC and attacks, believing her involved in Vanilla's disappearance.

  • Dual Boss: Her original boss design was intended to be a fight together with her sister. This concept is later realized in the Halloween DLC.
  • Expy: Of Chocola from Nekopara. Both are black-colored catgirls and the older, more outgoing sister of their sisterly duo.
  • Marathon Boss: Their boss fight in Halloween DLC. You fight against 2 bosses with 50+ more level than the Post-Final Boss, have 40 health bar, lots of attack pattern, and moves constantly.
  • A Wizard Did It: Her artbook profile says that her strapless top is held up by magic... and made of paper.

The Younger Cat-Eared Sister

The younger of the Cat Girl sisters. She is found at the top of the Sky Bridge. She is immediately suspicious of Erina and attacks her in self-defense.

  • Dual Boss: Her original boss design was intended to be a fight together with her sister. This concept is later realized in the Halloween DLC.
  • Expy: Of Vanilla from Nekopara. Both are white-colored catgirls and the younger, more reserved sister of their sisterly duo.
  • Marathon Boss: Their boss fight in Halloween DLC. You fight against 2 bosses with 50+ more level than the Post-Final Boss, have 40 health bar, lots of attack pattern, and moves constantly.
  • A Wizard Did It: Her artbook profile says that her strapless top is held up by magic... and made of paper.

The Older Twin in Winter Clothes

A bear who occupies the ruins of the Aurora Palace with her younger sister. She is suspicious of Erina's intentions in convincing her to go to Rabi Rabi town but eventually agrees if Erina plays with her.

  • An Ice Person: Like Rita, all her attacks are ice-based, with snowflake projectiles and even snowflake-shaped bullet patterns, as well as the ability to create big snowballs to use against Erina. She can also submerge the entire arena in water temporarily, slowing down Erina unless she has the Water Orb.
  • Beary Friendly: Unless you have to fight her, then...
  • Dual Boss: Like with Chocolate and Vanilla, her boss fight was to be together with her sister.

The Younger Twin in Winter Clothes

The younger of the bear sisters, Erina encounters her on the Icy Summit. Nixie attacks Erina after eating the local wildlife which, as Nieve later explains, impairs the eater's reasoning.

  • An Ice Person: Similar to her sister, her attacks are ice based, despite the fact that the ice she uses is red rather than her sister and Rita's blue. For some reason.
  • Beary Friendly: Unless you have to fight her, then...
  • Big Eater: Trying to eat a local plant that happens to look like a particular type of sweets gave her trouble, resulting in the battle with Erina.
  • Dual Boss: Like with Chocolate and Vanilla, her boss fight was to be together with her sister.
  • The Stoic: Compared to her sister, she isn't very talkative. While this can be handwaved as her being under the influence of the plants she just ate, even after she's brought back to normal, she's relatively quiet.
  • Sweet Tooth: When you find her, she's trying to eat the nearby candies in the arena. Unfortunately said candies are actually plants that drive her to attack you.

The Graceful Dancer

A dancer and close friend of Irisu. She confronts Erina, suspecting she is bullying the retreating Irisu.

  • Bully Hunter: The whole reason she attacks you the first time is because she thinks you're bullying her friend Irisu, who runs away every time she sees you. After she learns the truth from Irisu, she becomes suspiciously friendly towards you, and outright denies having ever been angry with you in the first place.
  • Curtains Match the Window: When her hair changes color, her eyes do too, but only in the sprites. In the CG art her eye color remains the same.
  • Glass Cannon: Her 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.
  • Lava Adds Awesome: In her third and final boss fight in the Volcanic Caverns, she can cause lava to flow across the bottom of the room, inflicting damage if it touches you.
  • Leitmotif: Brawl Breaks plays in all three of her battles.
  • Little Bit Beastly: Has fox ears and fitting tail.
  • Master of None: She knows many different types of magic, but doesn't excel in any of them.
  • Playing with Fire: In her third battle, all of her attacks inflict the Burn debuff, and her special attack makes lava rise up from below the room.
  • Power Dyes Your Hair: Her dances use different magic types and change her hair accordingly.
  • Recurring Boss: She need to be fought 3 times in order to recruit her.
  • Secret Keeper: It's heavily implied that, just before your second fight with her, Irisu confides in her that she's the leader of the UPRPRC. She keeps it secret and fights Erina to stall her so that Irisu can get away from her. Unfortunately, she's not very good at it, as by the end of the game, Ashuri, Saya, and Rita also know, having overheard the truth.
  • Spell My Name with an "S": Her artwork on the loading screen gives her name as Kotori, in keeping with how her name would be romanised if written in Japanese kana (コトリ Kotori). Probably enforced to add to the Animesque feel of the game, as the developer GemaYue is not actually Japanese, but Taiwanese.

The Princess of the Pyramid

  • Ambiguously Brown: To go with her Egyptian theme.
  • Ambiguously Human: It's stated she belongs to a seldom-seen race of humans, which may explain her longevity.
  • Barrier Maiden: One of three, along with Rita and Ashuri, responsible for keeping the barrier around Rabi Rabi Island up.
  • Gravity Master: As the wielder of Chaos Rod that can create gravity field that slow anyone inside it, she's this.
  • Really 700 Years Old: She's lived for several hundred years.
  • Stripperiffic: Probably the most notable example. At least Kotri and Seana justify it by being a dancer and a mermaid, respectively. Pandora has no excuse.
  • Who Wants to Live Forever?: She's immortal, though she isn't all that enthusiastic about it, pointing out that she'll outlive everyone she knows.
  • Wistful Amnesia: Possibly owing to her long age, she's the only character that seems to remember some events that Noah had wiped from everyone's memories three years ago, though she's just as confused as to why she knows these things.

The Sorceress With a Lust for Research

A witch encountered on Rabi Rabi beach and the Golden Riverbank. She immediately takes an interest in Erina, demanding she let her experiment on her.

  • Barrier Maiden: One of three, along with Rita and Pandora, responsible for keeping the barrier around Rabi Rabi Island up.
  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "Lust for Research Ashuri".
  • Cute Witch: A teenage witch with cutesy lasers and stars, and complete with conical witch hat.
  • Expy: Of Marisa Kirisame, what with the love for lasers, stars and explosions, and generally being a Cute Witch.
  • Naughty Birdwatching: Possibly. The (non-canon) 4koma leaves no doubt.
  • Outdoor Bath Peeping: Ribbon blames her for doing this while she was taking a bath.
  • The Peeping Tom: She insists that she was only spying on Ribbon for research purposes. Ribbon isn't buying it.
  • Wake-Up Call Boss: Her second boss fight is meant to be tackled later in the game, but it's rather easy to get to her much earlier. Needless to say, if you bump into her shortly after Cicini sends you to find Syaro, you're going to be in for a nasty difficulty spike. If you're the type that likes to explore, you may encounter her early in the game when she's considered a mid-game boss. It funnily also serves as a kind of punishment for not listening to Cicini when she tells you to go the other way.

The Embodiment of the Green Forest

A woman who inhabits the upper regions of the Starting Forest where she became trapped after merging with the plant life. She attacks Erina under the influence of the bunny phenomenon.

  • Darker and Edgier: Her short backstory happens to be the most depressing one. She says she came to the deep part of the forest to commit suicide. And while she didn't die due to the plants overtaking her, she's still become very mentally unstable that she considers her forest entrapment a much better view of life. One has to wonder what exactly happened to her, especially considering how Rabi Rabi Island has a generally easy-going society.
  • Enthralling Siren: Erina and Ribbon investigate a voice coming from inside the forest. Subverted in that she doesn't carry any malice when they find her, then played straight after the bunny phenomenon shows up.
  • Godiva Hair: She technically doesn't wear any clothes at all; her upper-body modesty is preserved only by a pair of strategically-placed locks of hair.
  • Plant Person: A plant girl, but she was not always one.
  • Token Adult: Compared to the rest of the cast who are teens and pre-teens, she and Lilith are at least nearing their twenties. She mentions that she has spent significant time in the forest.
  • Transflormation: It is not exactly known why, but she was used to be a human before being turned into a plant girl.
  • Wounded Gazelle Gambit: Pretends that she's being attacked in order to lure people to her. Fortunately, all she wants to do to Erina when she shows up is talk to her (at least until the Bunny Phenomenon happened.)

The Seductive Night Hunter

A succubus that frequents Sky Island town. She confronts Erina after she refuses her advances.

  • Clipped-Wing Angel: Claims she's even tougher in the air, but if you have any experience with Bullet Hell shmups you'll be way more in your element during the Unexpected Shmup Level and can take her down pretty quickly.
  • Even the Girls Want Her: There are a few girls in the Sky-Island Town that want to get spirited away by her.
  • Fade to Black: Lilith has an attack that results in this. She stuns Erina with heart projectiles, then walks up to her and does...something to her while the screen fades to black and Erina takes three hits for 69 damage each. Notably, this is one of the very few attacks whose damage doesn't scale with level (thus making it especially dangerous in a 0% run).
  • Fixed Damage Attack: The stun attack is one of the few attacks that deal a fixed amount of damage instead of scaling to the boss' level.
  • Horny Devils: She's notorious for spiriting away cute girls and comes on to Erina the moment she lays eyes on her. Fitting with the trope, she replenishes her mana by sleeping with women, and if you recruit her early enough to have her speak during a stele event, she implies she's been quite busy in Rabi Rabi town given the amount of mana she has to charge the stele.
  • LOL, 69: Her Fade to Black attack deals three hits for 69 damage each.
  • Lovable Sex Maniac: invokedEasily the gayest character in the game, which is saying something. She comes on to Erina immediately upon seeing her, and once she moves into Rabi Rabi town she considers it a "new hunting ground" for cute girls.
  • Multi-Stage Battle: She must be fought twice, first on foot, and then in an air battle reminiscent of a shoot-em-up game, with a long area with several enemies in between.
  • Projectile Kiss: Throws kisses and hearts during battle. Notably, they initiate a very powerful attack on contact.
  • Stripperiffic: Several characters are already this, but Lilith takes it up a notch, what with her being a succubus, with a translucent nightgown. She has an alternate outfit that's effectively lingerie, the top half of which gives her some pretty generous underboob.
  • Token Adult: Compared to the rest of the cast who are teens or even pre-teens, she and Aruraune are at least nearing their twenties.
  • Unexpected Shmup Level: The second of two battles with her is a Horizontal Scrolling Shooter rather than the usual platforming format.
  • Vapor Wear: The only thing she wears under that nightie is a bra and panties. The nightie is destroyed during the second fight with her.
  • Winged Humanoid: A pair of large bat wings, as befitting a demon.

     Keke Bunny
From Plurk

A strange bunny residing in Plurkwood.

  • Big Eater: She sometimes eats her own minions. Her Rabi-Rabi Town event is even just her sending Erina and Ribbon over to Plurkwood. Why? To get her more food, naturally.
  • Extreme Omnivore: Seems capable of eating just about anything, her own minions included.
  • Flunky Boss: Can summon the various creatures of the Plurkwood in her attack pattern.
  • Grievous Harm with a Body: Some of her attacks involve throwing a bunch of Meaty Bones at you, which explode into chunks when they hit the ground.
  • Guest Fighter: She's a mascot for Plurk.
  • Idiot Hair: Not the brightest bulb, since her main concern is eating many types of food.
  • Little Bit Beastly: Has rabbit ears, though whether she also has the tail is not certain.
  • Optional Boss: She's the only character you're allowed to skip on recruiting to enter the library in Chapter 8.
  • Vapor Wear: Wears nothing but panties under her robe.

The Mysterious Pajama Girl

The younger sister of Rumi. She sets the story in motion by abducting Erina and teleporting into the real-world.

  • Bonus Boss: Is one of the few bosses to have a much harder Special variant, "Miru Syndrome".
  • Demonic Possession: She is possessed by Noah in order to draw Erina back into the real-world.
  • Green-Eyed Monster: Before her battle, she expresses jealousy over how Erina is much closer to her sister Rumi than her, believing Erina to not like her. While Noah was possessing her at the time and influencing her behavior, its implied that these thoughts were always present in her mind, and just exaggerated by Noah.
  • Heavy Sleeper: As her design implies, she mainly stays indoors sleeping, rather than being active outside.
  • Room Full of Crazy: Her arena is full of creepy drawings of bunnies. Her music score is also one of the most sinister in the game.
  • Sdrawkcab Name: In Japanese, her name (ミル) is the reverse of her sister's name, Rumi (ルミ).
  • Songs in the Key of Panic: Her Leitmotif speeds up when her health gets low.
  • Stronger Sibling: Unlike Rumi, Miru does know magic, and powerful magic at that. It’s the reason Noah possesses her.
  • Teleport Spam: She constantly teleport around the arena like it was nothing. And you're limited to your melee attack for her boss fight. She has an attack pattern which is basically just spamming teleportation right on your exact location.
  • The Shut-In: She'd rather stay at home and play with Erina than go outside and meet other people, which is why she's fine wearing pajamas.
  • The Unfavorite: Seems convinced that she's this to both Rumi and Erina, thinking that they both love each other more than her.
  • Vapor Wear: She doesn't seem to wear anything under her pajamas. She puts on more clothes during the ending, when she's convinced to leave the house more oftem.

    Noah (Spoiler Character)
The Crystalization of Mana, Ideals and Emotions
Click here  to see Noah's original form

  • The Ace: Her past self was the strongest magic user in all of Rabi Rabi Island. Fittingly, she's the hardest boss in the game outside of the Bonus Bosses. And as "Erina the Forgotten Maiden", she is the hardest boss in the game, period.
  • Disc-One Final Boss: She's the boss of Chapter 5, and the instigator of the Bunny Phenomenon and Erina and Miru's disappearance. After her defeat, Miru returns home, everyone settles in after a job well done, the credits roll...and Chapter 6 starts.
  • Fallen Hero: From the hero who sacrificed herself to save Rabi Rabi Island, to the Big Bad putting it in jeopardy all over again in a desperate bid to return.
  • Final-Exam Boss: Near the end of the fight with her first form, she'll begin using patterns from some of the bosses you've already beaten. Does this again As Erina in her second phase.
  • Graceful Loser: After her defeat, she realizes how wrong her actions were and acknowledges that Erina has the strength to protect Rabi Rabi Island.
  • Grand Theft Me: Pulls this on Miriam in the post-game, but she means no malice behind it. She only talks through her to say goodbye to Erina.
  • Leitmotif: The Truth Never Spoken, No Remorse, and RFN - III. She's more associated with The Truth Never Spoken.
    • Finale as Erina. As befitting of the True Final Boss of Is the Order a DLC and the story as a whole
  • Multi-Stage Battle: She has three forms.
  • My God, What Have I Done?: After pushing the aforementioned Reset Button and exiling herself, she grew to regret doing so and devised a plan to replace Erina. Happens again after her defeat when she realizes how wrong her actions were.
  • Reset Button: Pushed this in the past, erasing everyone's memories so that Rabi Rabi Island wouldn't be discovered by the outside world. She also tells Erina in time she may have to do this as well after being defeated.
  • True Final Boss: Of Is the Order a DLC and the story as a whole as her past self: Erina the Forgotten Maiden, the former protector of Rabi Rabi Island.
  • Woobie, Destroyer of Worlds: She just wanted to return to Rabi Rabi Island.

How well does it match the trope?
