- Yonaka: J-just what is this?! This place... and those creatures !! They tried to capture me! Why? What are they after?
A Japanese schoolgirl who was on her way home to see her brother, only to fall asleep on the train and find herself stranded in the Mogeko world. Now she has to make her way through the mysterious Mogeko Castle to find a way back home.
- Action Survivor: She survives alone with her brother or Defect Mogeko.
- Big Brother Worship: The game's focal point is her strong attachment to her older brother.
- Blood-Splattered Innocents: This happens after King mogeko shoots Defect Mogeko.
- Emotionless Girl: Most of the game, she doesn't show any emotion.
- FaceHeel Turn: Does this in the normal ending, where she becomes the new leader of the Mogekos.
- Heroic BSoD: She's very unstable after Defect Mogeko (presumably) dies trying to protect her and after seeing her living room covered in her parents' blood and guts.
- He Who Fights Monsters: Starts out an innocent schoolgirl trying to escape but by the Normal End, she's killed several innocent Mogekos, including ones that were just trying to help, and usurped the Mogeko leaders, becoming a monster even they fear. She's all set up to be the sequel's villain.
- Icy Gray Eyes: Fitting the typical associations with gray eyes, she is stoic and shows inner strength, not letting things affect her too much... which is kind of required, because otherwise she would go insane very quickly.
- In the Blood: Being that her brother Shinya is quite the nutcase, and that Yonaka has half a mind to use her knife on so many of the friendly Seven Special Mogekos, and that there are some Mogekos she will not let players stop her from butchering, just for entering conversations with them, it can safely be said that something's seriously screwy in the Kurai household. She also doesn't seem all that bothered by her brother's insanity. And of course, the normal ending has her take over the castle. To top it all off, it's implied that she will be the Big Bad of the sequel.
- Make Way for the New Villains: In the Normal Ending, she kills Shinya, brings Moge-ko to heel, and crushes King mogeko to death then uses his scalp as a makeshift crown, before finally declaring herself the new king of Mogeko castle.
- Nice Girl: At heart, Yonaka really is a good-natured girl at first. Not that the Mogekos are interested in her personality.
- Ordinary High-School Student: She's a normal high school girl thrown into a world of total madness, and has to deal with it all, preferably without going mad herself.
- Peek-a-Bangs: One half of her face is covered by her bangs.
- Protagonist Journey to Villain: Considering that the Gaiden Trailer reveals the Normal End is (seemingly) canon, Yonaka has seemingly usurped King mogeko... only to become a cruel tyrant that surpasses Moge-ko herself. In fact, she's possibly even worse than the King, as she has no fear of asserting herself to Moge-ko and makes it dreadfully clear she's in charge by sitting on her.
- Red Eyes, Take Warning: In the Normal End, she gains these, likely to foreshadow her FaceHeel Turn. The title card even shows her with red eyes.
- She Is the King: As Lord Prosciutto. Instead of 'Lady Prosciutto.'
- She also goes by King Yonaka, instead of Queen Yonaka.
- Stronger Than They Look: Surprisingly, Yonaka has a grip strength of 70. Keep in mind the "strong" norm for females around her age is usually 30. Considering she can stab several Mogeko and even her brother and kill them in one fell swoop, it hints at how dangerous she can really be if pushed.
- Trapped in Another World: Either true ending (and a few of the bad endings) implies that she's, willingly or unwillingly, stuck in the Mogeko universe.
- Ungrateful Bastard: Optionally, she can murder the few decent Mogeko in the castle immediately after they help her including the guy who gave her the knife for protection in the first place.
- Videogame Cruelty Potential: Yonaka can steal prosciutto from a few Mogekos and leave them in tears, destroy a switch trapping some in a cage forever to starve to death, and kill quite a few of them. None of these Mogekos do anything to hurt her she can even kill the ones that helped her.
- When She Smiles: It's truly a sight to behold.
- Woobie, Destroyer of Worlds: Considering all the crap she's been through, from repeated Attempted Rape by the Mogekos to her brother trying to kill her, it is no wonder that Yonaka decides to overthrow her tormentors and become a sadistic dictator herself in the normal ending.
- Yonaka: Er You're a Mogeko as well .?Defect Mogeko: Right. But wrong.Yonaka: Eh?Defect Mogeko: I'm a defector. Bit different from the lot of them.
A strange green Mogeko locked in a cell with Yonaka. Unlike a majority of the other Mogekos, he has no desire to pursue her and helps her escape Mogeko Castle. He's revealed to be the final Special Mogeko, and he performs a Heroic Sacrifice to help Yonaka escape.
- An Arm and a Leg: When he's seen after his final fight with King mogeko, he's lost his left arm.
- Color-Coded for Your Convenience: His green fur makes him stick out like a sore thumb among all that yellow.
- Defector from Decadence: Literally, he is distinguished by being a Mogeko who has morals and ethics, in stark contrast to the king and his minions, who are almost all ultra-hedonistic, amoral bastards.
- Heroic Sacrifice: He uses his blood to mask Yonaka's scent, and he goes out to ward off the Mogekos and King mogeko.
- Mr. Exposition: He tells Yonaka about Mogeko Castle's history, Moge-ko, the Seven Special Mogekos, and King mogeko.
- Scars Are Forever: He has a huge scar on his chest and he's missing his left ear.
- Single Woman Seeks Good Man: In a castle full of sex-obsessed perverts Defect Mogeko is the one she'd actually be willing to elope with.
- Walking Spoiler: To reveal what and who he really is would spoil the last part of the game.
- Moge-ko: Hey, now, why are you runniiing? No, no, I wanna play! .Oooh, I see, it's tag! GYAHAHAHAHAHA!!!! I'll chase you to your GRAVES!!!!!!
A homicidally insane human-Mogeko hybrid girl who rules over the fourth floor of the castle with an iron fist. Originally created to be the perfect little girl for the Mogekos to have their way with, they screwed up the recipe, using cement instead of candy. The result is less than pleasant.
- Ax-Crazy: While almost everyone is unstable inside Mogeko Castle. Moge-ko takes things Up to Eleven, as she's a completely unpredictable psychopath who does whatever she wants to whoever she wants, and nobody can do anything to stop her.
- Bad Boss: She torturers her Mogeko underlings so much that pretty much all of them, even the king, are scared of her.
- Big Bad Ensemble: With King mogeko and Shinya Kurai. She is one of Yonakas main enemies in her quest to escape the castle, and is not all that loyal to the king.
- The Caligula: Her dictatorship turns the Mogekos living on her floor into broken wrecks. And broken corpses.
- Cute and Psycho: Looks adorable, and is the most insane and dangerous person in the castle.
- Dangerously Short Skirt: Although you don't see below her waist often, this is what you see when you do.
- Deflector Shields: Has one as a special skill, Moge-ko Shield. It's strong enough to stop an RPG without issue.
- Depraved Bisexual: She has the same high school girl fetish as the regular Mogekos, and also mentions loving boys as well. She's also a complete hedonist who gets off to torture, mutilation, possibly BDSM, and allegedly also enjoys cannibalism.
- Dragon-in-Chief: King mogeko has no control over her and is utterly terrified of her. The only reason he is the king is because she doesn't seem interested in ruling the castle.
- The Dreaded: Exactly zero Mogekos feel so much as a tingle of lust for Moge-ko, in spite of her having schoolgirl-esque girlishness dribbling out of her pointy yellow ears. They're all THAT terrified of her. Even Defect Mogeko and King mogeko are terrified of her, which says a lot.
- Eviler Than Thou: The Mogekos are rapists who are obsessed with high school girls, but Moge-ko is also a rapist who is obsessed with high school girls, and torture and cannibalism as well. She also preys on the Mogekos.
- Evil Gloating: Does this at times, although it doesn't hinder her as much as some examples.
- Face of an Angel, Mind of a Demon: Looks adorable, but is more dangerous than anyone else in the castle.
- Femme Fatalons: Has some nasty looking ones in the Gaiden trailer.
- Gone Horribly Wrong: Moge-ko was created with the intention of being the perfect little girl so the Mogekos can have their way with her, but they messed up the recipe, so while Moge-ko was a cute girl, she was also a complete psychopath who is far worse than the Mogekos, who end up being her prey.
- Half-Human Hybrid: She's half-human and half-Mogeko.
- Hidden Depths: Possibly. In Bad End 4, she asks Yonaka if she really wants to go home, and after she stumbles over her words before saying yes, Moge-ko tells her that fooling yourself is one way to live.
- Horrifying the Horror: She does this to King mogeko, who created Mogeko Castle, in the Normal End. When he tells her Yonaka got away, she angrily tells him that she'll have to play with him, causing him to burst out crying.
- I'm a Humanitarian: According to Defect Mogeko, she eats the Mogekos she kills.
- It Is Pronounced "Tro-PAY": Note the hyphen in her name.
- Knife Nut: She is seen wielding a knife on several occasions, and doesn't use any other weapon. It's heavily implied that she uses them in torture sessions, and possibly during sex. Or both- to her, there is no difference.
- Little Bit Beastly: She looks very human, but she has Mogeko ears on her head and a Mogeko tail.
- Rainbow Text: Her dialogue text will turn blood-red whenever sh's saying especially horrifying words.
- Red and Black and Evil All Over: Wears a nice red miniskirt and red shirt with black cuffs, along with a black waistcoat, tie, boots and socks.
- Red Eyes, Take Warning: Her eyes briefly flash to red when she's thinking of something truly diabolical.
- Sadist: Torturing people for fun is one of her hobbies. On the other hand, having the tables turned on her is something she really doesn't like.
- Slasher Smile: Often sports some terrifying ones, especially when she's thinking about something particularly sadistic.
- Split Personality: Implied to have this, as she almost instantly swings between fairly affable (even friendly) to psychopathic Torture Technician and mass murderer.
- Third-Person Person: Slips into it from time to time.
- The Woman Behind the Man: Even King mogeko is afraid of this girl, meaning she probably holds far more power and authority over the castle than he does.
- Waistcoat of Style: A nice black one that gives her a smart look that goes well with her cuteness, and makes her look less like the nutcase she actually is.
- You Need to Get Laid: Played with. She doesn't actually have any problems getting laid as she simply rapes whoever she wants, but in the Bad End 4 she captures Yonaka and locks her in her torture room, after which the Mogekos on he floor note that she has calmed down a little since having Yonaka as a toy allows her to let off bottled up stress. This has such a big impact on her that not only do the Mogekos are able to muster up the courage to ask her to share Yonaka, but she only gives them a death threat, which is actually pretty nice compared to some of her more extreme behaviour.
- King mogeko: Welcome to Mogeko Castle, AKA Mine!!!
The leader of all the Mogekos and the owner of Mogeko Castle.
- all lowercase letters: His name is always written "King mogeko" or just "mogeko". Even someone screaming his name would be written "mOGEKO".
- Animalistic Abomination: That cyclops form of his.
- Big Bad Ensemble: With Moge-ko and Shinya Kurai. He's the one pulling the strings in the castle and the final enemy.
- The Caligula: Also this, but to a lesser extent than Moge-ko.
- Entitled to Have You: He may have this attitude towards Yonaka.
- Even Evil Has Standards: Even he's afraid of Moge-ko.
- Evil Twin: Presumably, this is the case for him in contrast to Nega-Mogeko.
- Fisher King: He was the original creator of the Mogekos, and Defect Mogeko mentions (and the Seven Special Mogekos, who King mogeko personally created, all imply) that the kingdom was a pretty nice place to live before King mogeko got Drunk with Power and turned into the evil molestation-happy psychopath he is now, which also doomed his subjects and kingdom to depravity.
- Hero Killer: He ultimately overpowers Defect Mogeko and has him burned alive. Although, the trailer for the next game implies that Defect Mogeko lives.
- Sorcerous Overlord: Probably. He's not omnipotent nor even that bright, but he's the creator of the Mogeko and the world they live in. Alternatively, given his final altercation with Nega-Mogeko, he may be an Eldritch Abomination.
- The Wrongful Heir to the Throne: Maybe. It's stated that things were much nicer before he took to the throne.
- Mogeko: Come! Let us play! In a sexual sense!
A species of small catlike creatures who bring high school girls to their world and engage them in sexual activities.
- Abhorrent Admirer: Almost all Mogekos are ultra-hedonistic, amoral little bastards. They're also obsessed with high-school girls, and Yonaka is one of those...
- A Date with Rosie Palms: They tend to masturbate while looking at porn.
- A Dog Named "Dog": Nearly all Mogekos are named Mogeko.
- And Now You Must Marry Me: Ending 0: "Everlasting dream on our wedding night."
- Bad is Good and Good is Bad: Mogeko society glorifies carnal indulgence, including violence, gluttony, and most especially all-consuming lechery. Those beset with insufficient libido or ethical qualms are put on death row as 'Defects.'
- Cute and Psycho: Don't be fooled by their appearance. They may look cute, but they're crazy, obsessive, and very violent.
- Date Rape: Presumably what they do with every girl they kidnap. In the first Bad End, they all rape Yonaka.
- Easily Forgiven: After Yonaka is possessed by Lord Prosciutto is to forgive all the Mogekos for all their sins.
- Ephebophile: With rare exception, practically every one in the species lusts after high-school girls in truly the worst possible way.
- Hive Mind: They try to have this, up to and including executing those who don't conform.
- Stalker with a Crush: A possible explanation as to how they know Yonaka's name and everything else about her. It's either that or mind reading. Maybe both.
- Trademark Favorite Food: Prosciutto. So much they made a religion around it.
- You ALL Look Familiar: Nearly all Mogekos look identical. Even their king looks no different (he doesn't even wear a crown or coat).
- Zerg Rush: When they're at their most dangerous. If Yonaka isn't quick enough, they can catch up to her pretty fast.
- Mad Mogeko: GAAAAAAAAAAAAA!!!
Hordes of Mogekos who are all homicidal and insane. Most of them have been locked up behind bars.
- Gang Up on the Human: ...Thank goodness for walls. 90 percent of the time, anyway.
- Eaten Alive: These guys crave Yonaka's tender schoolgirl flesh in the OTHER way...
- Insane Equals Violent: There's an awful lot of blood in their fur
- Mighty Roar: Constantly.
- No Zombie Cannibals: None of them think to devour each other.
- Schmuck Bait: Go ahead, Yonaka. Press that button that'll set them free.
- Zerg Rush: Sometimes Yonaka will enter a room full of numerous 'sane' Mogekos, and there's a chance they won't rush to rape her. Mad Mogekos will always Zerg Rush in Yonaka's direction, the moment they sense her presence. ALWAYS.
- Mogeko Larva: Mama!
Infant Mogekos, who have yet to become depraved monsters.
- Face Full of Alien Wing-Wong: Although Mogekos usually reproduce by vomiting eggs when they hatch into Mogeko Larva, the Larva can do this using humans to create huge amounts of Mogekos, which Yonaka can find out the hard way.
- Zerg Rush: Yonaka can find a room full of Mogeko Larva, who swarm her and use her body to spawn more Mogeko Larva.
- Zombie Mogeko: O orgh
- Body Horror: Oh yes. Parts of them are flat-out missing and they're bloody all over.
- No Zombie Cannibals: They don't attack anyone, and apparently they like fragrant olives.
- Obfuscating Stupidity: They pretend they can't speak, but they're actually quite intelligent.
- Our Zombies Are Different: They are absolutely no threat to Yonaka or Defect Mogeko or anyone. They're even noted to be surprisingly intelligent and enjoy gardening.
- Mofuko: Fluff!
- Bookworm: Reading books is a popular pastime among Mofukos.
- Took a Level in Kindness: Mogekos who become Mofukos become peaceful and completely uninterested in any activity requiring a libido.
- Too Good for This Sinful Earth: Mogekos become Mofukos when infected with blancfluff mogeparasites. They're much nicer than Mogekos, but the infection inevitably leads to death within a month of transformation.
- Verbal Tic: "Fluff?"
The Seven Special Mogekos
- Somewhat Strange Mogeko: No need to fear me. I won't attack you. I much prefer... to just sit here and drink tea, you see.
The Special Mogeko of the castle's first floor.
- Chivalrous Pervert: He has absolutely no intention of forcing himself upon Yonaka. His bookshelves are still filled with porn, and his diary keeps track of his own masturbatory sessions and bowel movements.
- Spot of Tea: He'd rather quietly drink this stuff than molest high school girls.
- The Adjectival Man: "Somewhat Strange" being a fairly good description; after all, he isn't obsessed with the things the other Mogekos are. He just wants to read and drink tea for the most part.
- Prosciutto Fairy: They're a noisy bunch, aren't they? No decency, I say. That's why I hate them so. Why must we be on the same floor, I swear.
The Special Mogeko of the castle's second floor.
- Blood Spirit: Be careful. You know what awaits there.
The Special Mogeko of the castle's third floor.
- Blood Is the New Black: He's constantly covered in it. Hugging him is a bad idea.
- "Darkness von Gothick" Name: Blood Spirit is not a misnomer.
- The Quiet One: The least talkative of all the Special Seven.
- Sugar-and-Ice Personality: According to Mogecuckoo and Defect Mogeko, he's actually pretty exuberant when he doesn't have to talk to cute girls.
- Hasu: I wanted to play with you all again.
The Special Mogeko of the castle's fourth floor.
- Desecrating the Dead: The game gives you the option to cut up Hasu's corpse.
- Good Shepherd: Implied to be something like a priest or minister in the Mogeko kingdom.
- Holy Halo: Hasu had one floating over his head long before entering Prosciutto Paradise.
- Made of Iron: He withstood being crucified for God only knows how long.
- We Hardly Knew Ye: By the time the heroes meet him, he's about to expire from being crucified by Moge-ko.
- Moffuru: Yes, I've had the monster mistake me for a Mofuko and nearly eat me many a time.
The Special Mogeko of the castle's fifth floor.
- Ridiculously Cute Critter: The only Mogeko who is naturally fluffy and who won't meet a tragic end. Unlike the Mofuko.
- Yonaka: Why's a bird in the library?Defect Mogeko: No real reason.
The Special Mogeko of the castle's sixth floor.
- Clucking Funny: As he is a chicken-themed Mogeko, he clucks a lot. He's also a friendly one and makes some bird puns.
- Pungeon Master: Though his screentime is brief, the dialogue he does have indicates that he's fond of bird-themed puns.Mogecuckoo: Cluckily, we moved [the library] over here in time!
- We Hardly Knew Ye: He's mortally wounded while trying to help Yonaka and Defect Mogeko escape.
- Shinya: That's right. ..It's exactly what you think.
Yonaka's older brother who has come home.
- Aloof Big Brother: Not a terribly severe case, but he was often lost in thought, to the point that Yonaka was worried about him. Possibly foreshadowing his mental instability.
- Ax-Crazy: Yonaka took too long to come home, so he spent his time waiting by dismembering his family.
- Big Brother Instinct: Presumably was doting to his little sister. That is, before he became a sadistic murderer.
- Cain and Abel: With himself as Cain, and Yonaka as Abel.
- Dying as Yourself: Only in the Happy End, though. (But his dialogue indicates that this was the case for both endings; he just died before he could say anything in the Normal End.)
- Final Boss: He's the last pursuer in the game.
- Hidden Eyes: For the majority of his onscreen appearances.
- Idiot Hair: As pictured. But don't let the cowlick fool you, Shinya's not actually an idiot so much as severely unhinged.
- Mysterious Past: Precious few concrete facts are revealed about Shinya, especially why he went away from his home and family for a time.
- Plot-Irrelevant Villain: While he's the crux of Yonaka's character arc, he doesn't seem to have anything to do with the main plot involving the castle.
- Red Eyes, Take Warning: Normally has gray eyes like Yonaka, but they turn red when he goes into madness mode.
- Self-Made Orphan: Brutally murders his parents while waiting for his sister to come home. Implied that he wished to do the same to her. He actually does in Bad End 7, "Fictitious Truth".
- Walking Spoiler: This is the reason he's not in the "Main Villains" list.
- Would You Like to Hear How They Died?: When it comes to informing Yonaka how he reduced their parents into so much featureless raw meat, Shinya isn't a stingy brother.
- Lord Prosciutto: .....I forgive the sin of all Mogeko.
A god related to prosciutto who the Mogekos seem to venerate when not thinking about schoolgirls.
- Ambiguous Situation: Is he in control of Yonaka or mearly sharing her body.
- Demonic Possession: What he does to Yonaka. Although if he's in control is unknown.
- Eviler Than Thou: Seems to be this to Moge-ko, who ends up being used as a chair.
- Power Floats: Starts floating after he possesses Yonaka.
- Villain of Another Story: From the looks of the Gaiden Trailer, Lord Prosciutto seems to be the villain of the game.
- Mogekov: Now let me say this, human, I was NOT crying, understood?! Absolutely not!!!!!
- Color-Coded for Your Convenience: His fur is a snowy white, as well as his soldiers'. Also apparently he and his soldiers aren't even Mogekos, just "something very similar".
- Glorious Mother Russia: He claims he needs to go back to Moscow. He's also supposedly a Russian General and a massive patriot.
- Inelegant Blubbering: When he thinks he's alone.
- Hero of Another Story: He's slated to star in 'Mogeko Castle Gaiden: General Hashasky's Great Adventure.'
- Men Don't Cry: When he knows he's not alone.
- Nice Hat: Not even the King wears a crown, but Hashasky's sporting one fine ushanka.
A Hashasky-human hybrid that serves as a underling for the General.
- Nice Hat: Sports a ushanka that covers her Hashasky ears.
- Hashasky: General!
