Protagonist

     Peter/Petra 
The poor guy chosen as Fate's chew toy.
  • Accidental Proposal: When Victor has his mind-controlled lackeys throw Petra's resurrection pin in a pool of lava and then sent Rocks for Brains at her, she dodges in a way that a boulder lands on his head. Rocks for Brains is immediately smitten by her, thinking she did that on purpose, since Rock giants like himself throw boulders at the object of their affection.
  • Animal Motif: A rodent, like a rat or mouse. They are well-known for their cowardice because they know they're at the bottom of the food chain, or close to it. They are also well-known to be surprisingly clever and cunning and their loyalty to those who treat them kindly is legendary, with many a fable or aesop being written about it. Last, but not least, rats and mice are surprisingly vicious when protecting their loved ones or when they're cornered. The phrase "the rat bites the cat" is not only common, but a cautionary tale.
  • Antivillain: She's only a villain because she's forced to attend a villain school, where Virtue Is Weakness is heavily in play, and the curriculum is all about how to do nastiness and get away with it. Failure to learn often results in death.
  • Attractive Bent-Gender: To her horror, being gender-bent has made him, now her, a total Dude Magnet, and having her breasts made bigger by one of Michael's "pranks" doesn't help.
  • Can't Get Away with Nuthin': While in the nurse's office with a patient harmed in magic class 101 by a magical mishap, she swipes some random potions to try and up her chances of survival in Sir Grieve's week-long detention. Unfortunately for her, the potions she took were mislabeled, thanks to a "prank" from unidentified upperclassmen who used magic to make the labels jump around. The results are... messy. Cue more of that lovely Trauma Conga Line.
  • Chaste Hero: Well, chaste anti-villain. She's way, way too stressed about trying to survive her indentured academic career to be concerned with romance or sexuality, or even exploring her new very attractive feminine body.
  • The Chewtoy: As lampshaded by Bob, her subterfuge teacher who tells all the other teachers during their betting pool that Petra is Fate's chew toy.
  • Combat Pragmatist: Not being built like a tank, nor being a powerful archmage, she's got no choice but to fight dirty.
  • Conditioned to Accept Horror: After only a week of the wackiness at Doom Valley, she's not only completely unfazed when she learns that a monster actually lives under her bed, she actually pays the creature a visit, shares her life story with it, and considers the creature a decent host, accepting tea, cookies, and head-pats, before she has to shuffle off to Ella and endure the rest giving her (horror) Beauty Treatments, that she doesn't like.
  • Cowardly Lion: Petra flees combat whenever she can, but if her friends are in trouble, she will march right into the thickest part of the battlefield for them. Case in point, when Rocks for Brains throws a boulder at Petra and Calcie throws one back, Sir Grieve detains Rock for Brains and Petra for detention. Rather than throw Calcie to the dragons, Petra accepts responsibility for the rock throwing.
  • Crouching Moron, Hidden Badass: Which Clarice picks up on and lampshades in chapter 40. When visiting the on-campus game room and playing a tactical game with holographic army units, Petra completely cleans the clocks of three of her friends with a goblin army, known as the weakest units in the game, through clever tactics, strategies, and biding her time to use her forces at their most effective. When a group of four girl-bullies decides Ella's friends have been "acting like they own the place" and tries to pick a fight, Clarice spells out how Petra tends to be very dangerous when cornered and warns that even if Petra's fate is likely to be humiliating, their fates are going to be worse. This is after the louts refused to back off when Naomi reminded them that Ella loves to hire experts, to deal with her problems, Rock for Brains is Petra's nominal boyfriend, and the insane Blood Wing is a connection they effectively have on speed-dial for dealing with fools that want to start something.
  • Does This Remind You of Anything?: When she's attacking a giant spider who was keeping Rocky from recognizing her attempts at flirtation, she yells out "MY PRECIOUS!"
  • Doomed New Clothes: Her clothes just never seem to last! On day one, getting gender-swapped made it so Peter's clothes no longer fit on Petra. Her nightgown was ruined on her first "survival" test. Her clothes no longer fit again when Michael gas-bombed her with "candy" that caused her hips and breasts to grow substantially. Ella and the others buy her a lovely red dress to entice Rocky with, and Barbarina literally tears it to shreds in the mess-hall. Lastly, her clothes don't survive the first day of detention.
  • Driven to Villainy: Peter/Petra never wanted to be a villain, but now they have to undertake villainy in order to survive.
  • Dude Magnet: Ever since Peter was turned into Petra, the guys have been lining up around the block for a shot at her, romantically. Garth, Reginald, and even the half-giant Rock for Brains all find her irresistible, though Petra will have absolutely nothing to do with the self-righteous blowhard Reginald.
  • Foreshadowing: There's a reason Peter is shown waking up from a nightmare of speaking with a woman with dice for eyes in chapter 1...
  • Had to Be Sharp: On the very, very first day of tests, she's the only one to actively survive her "Do or die" competition test with a counterpart from The School of Righteousness and Honor. All the rest, including Ella, died an Undignified Death and were resurrected.
  • Hoist by His Own Petard: In the chapter, "I HATE BEING A CATGIRL", Petra finds herself Swallowed Whole by a frog monster she just hit with a smoke bomb as she was trying to escape. Problem is, Petra's a cat girl and, too late, she realizes that the active ingredient in the smoke bomb comes from a plant in the catnip family. Intoxication Ensues.
  • Hot as Hell: In Petra's most recent shapechange, she made a deal with a Lilin, a lust demon, trading her catgirl shape for the demon's sexy curvy shape. Her breasts are now big enough she's worried that running could potentially break her nose and give her two black eyes.
  • Idiot Ball: On the way to Doom Valley, she accepts a piece of chocolate from Michael, who is a complete stranger, after they shared their trepidations. Peter becomes Petra upon awakening. They never make this kind of mistake again.
  • Improvised Weapon: When Victor tried to use mind control on Ella, Petra, and the rest of the clique, and went for his sword when Petra retaliated, Petra beat him down using a food serving tray.
  • Immune to Mind Control: Though the true mechanics have yet to be revealed, Petra seems to be highly resistant to mental manipulation, to the chagrin of Michael and Victor, the former using drugs with post-hypnotic suggestions and the latter being a psychic with mind-control powers. It doesn't help that both antagonists have tried using controls that were strongly against Petra's inherent nature which had her actively rebel against the commands.
  • Indy Ploy: She can wing it like a pro, putting together rather chancy plans on the fly when she's in trouble.
  • Inept Mage: Magic classes just don't work for her, at all. She repeatedly tries her best at following the curriculum, but she just winds up with minor mistakes that cause her to lose control of her magic.
    • Day 1: She is tasked with showing a spell she already knows. She manifests a flame lighting cantrip she learned in the local equivalent of the Boy Scouts. It works. She tries to dispel the flame only to have it turn into a fireball and fly towards her own head.
    • Day 2: She's asked to try an invisibility spell. She mis-speaks and only makes her clothes invisible in the middle of class.
    • Day 3: When testing a shield spell, she casts a minor cantrip [Force Bubble], which works as intended... for a second or two, but starts picking up momentum with each impact until it eventually crashes into Blood Wing with enough force to knock her out of her shield and through a wall. Blood Wing retorts "How the hell did you do that?!"
    • Day 4: When it's her turn to be shielded, she somehow manages to make a shield that boosts the magic it's hit with, turning a spell that normally summons a gentle breeze into a hurricane!
  • Misery Poker: When Petra, Ella, Naomi, Calci, and Clarice first compare notes about their tenure in Doom Valley, they compare what the family/clan gave them as a "parting gift." Petra gets comfort hugs from everyone when she mentions that all she got was a one-way ticket to the school...
  • A Mistake Is Born: Discussed. When chatting with Ella about their respective family situations, Petra mentions being an only child and suspects her parents apparently wanted to remain childless... Oof.
  • Open Mouth, Insert Foot: Exhausted after a particularly grueling Combat Training class under Angel Slayer, coasting along on pure adrenaline in chapter 41, she and Rocky get the detention task of collecting a Mock Hydra egg since Sir Grieve thought they were "unusually resilient." Before she can catch herself, Petra shouts out "ARE YOU TRYING TO GET US KILLED?! THERE ARE EASIER WAYS!" to the Stunned Silence of the second years present. She and Sir Grieve get into a staring contest, and Sir Grieve sends her to collect the egg, alone.
  • Painful Transformation: We can't be certain what it was like for Peter to turn into Petra, as they were unconscious at the time, but every transformation since then has been immensely painful. Getting her breasts and hips made bigger had her gorge herself on food and then collapse in agony, forcing a visit to the nurse's office. Being transformed into a Cat Girl at Ella's recommendation, to increase her odds of surviving detention, had her convulse in unbridled torment as her biology struggled to correct itself.
  • Phlebotinum Overload: Thanks to rapid-fire shapeshifts, mostly unwilling, her body's forgotten what it's supposed to be like and started shifting at random, starting in chapter 44 and moving on to chapter 45. Ella's brother Kai calls it "Rapid Transformation Syndrome" and Petra's got it bad. According to Kai, it's a miracle it hasn't happened sooner. It doesn't help that the nurse is pretty ticked that a certain someone swiped some potions before the start of detention. OUCH!
  • Reluctant Fanservice Girl: Ever since being gender-flipped, she's always shoved into a situation where her clothes are shredded, removed, made invisible, or just plain destroyed while she's in public, to her shame and humiliation.
  • Staring Down Cthulhu: In chapter 41, in a moment of adrenaline fueled panic and bravado, she calls out Sir Grieve for sending her and Rocky on a Suicide Mission. She and the teacher get into a staring contest, and he blinks first, but it doesn't help as Rocky is sent home, free of detention for the day, while Petra is sent on the task to collect a Mock Hydra's egg, alone.
  • Stopped Caring: She almost ends chapter 40 very, very happy until a collision with another student in the mess-hall gets her splashed with boiling hot tomato soup and she accidentally shreds her shirt trying to get the scalding hot liquid off before she's burned. She just sits at the table, resigned, and responds "Is there anybody who hasn't seen me half-naked yet?!" when Garth points out she's only a bra away from being topless.
  • That Didn't Happen: After being exposed to a plant in the catnip family while she's a cat girl, Petra gets very flirty with Rock For Brains and then goes into a jealous frenzy when she realizes that he's tied up fighting a spider the size of an elephant, surprising both Rocky and the spider with the sheer level of viciousness by which she attacks the arachnid, and then curling up into Rocky's chest, purring and trying to rub her scent on him, like cats are wont to do with people they like. When Petra sobers up, she gets Rocky to promise to never share what happened with anybody, not even herself.
  • Trans Tribulations: Being gender-swapped against their will has not been kind. Petra is almost always in an existential crisis for being a boy trapped in a sexy girl's body.
  • Unluckily Lucky: Her luck since her parents "generously" signed her up for Doom Valley Prep School has been atrocious, but it often loops back around on itself. Case in point: She oversleeps on the day of the surprise "survival test" because it was advertised as a rest day. She wakes up to find a note next to her bed stating the test starts at 1000 hours, and it's 0959. As she jumps out of bed, the clock rolls over to 1000, teleporting her to a dungeon cave. She stumbles about in her nightgown, eventually captured by a tribe of cannibal goblins, but this scenario is ideal for pulling the wool over Reginald's eyes to get him to be her meat-shield for the exercise, rather than have to fight him every step of the way...
  • Weakened by the Light: After trading shapes with a demoness, it seems Petra is now allergic to bright light. A magical blinding flash gave her a sunburn, and the demoness warned her to be inside by dawn. The warning came after making the trade of course.
  • Weirdness Magnet: As Fate's chew toy, she's a magnet for unbridled chaos, especially if it humiliates her in some way.

Allies

     Ella 
One of the many children of "The Immortal Mad Emperor Arp." She's introduced winning the bid for Petra's room key at the start and volunteers Petra to be her roommate as a result.
  • All Women Are Prudes: According to her brother Kai, she's a bit prudish and, in fact, faints when she accidentally gets a peek at Peter's "Mr. Happy." (His words.)
  • Ambiguously Brown: When she first appears she's described as a dark skinned girl with short crinkly hair.
  • Beauty Equals Goodness: Well, she's still a villain in a villain school, but she treats her friends and servants kindly and dotes on them. She also treats people with respect until they give her reason not to. She is also very physically attractive.
  • Beware the Nice Ones: She's a total sweetheart until she's given reason not to be, but once that line is crossed, a world of hurt awaits you.
  • Big, Screwed-Up Family: She's got over 350 siblings and well over 250 step-mothers with her father, "The Immortal Mad Emperor" having a harem of a size not seen since The Bible(specifically King Solomon), with every one of her relatives being willing to murder her by poison to get her out of the way. Not to mention all the court nobles who try to manipulate or murder her for their own interests too...
  • Conditioned to Accept Horror: It says something that she considers one of her few older brothers trustworthy because he's one of the few siblings who hasn't tried to kill her, and it's in his best interests to help with an experimental Cat Girl potion for Petra...
  • Friendly Address Privileges: She allows, nae commands, Petra to speak with her as equals, despite being a princess and Petra being a commoner.
  • Karmic Jackpot: She will see to it that those who treat her well have nice things happen to them. Those who treat her and her friends badly will have something bad happen to them sooner or later.
  • Living Emotional Crutch: She is the primary reason Petra hasn't collapsed into a fetal position, crying Tears of Fear in the dorm, refusing to come out.
  • Massively Numbered Siblings: She has at least 350 siblings, but new ones keep getting born and "unlucky" ones keep winding up dead, so she's not really sure.
  • Royals Who Actually Do Something: She's a princess and is an active part of the plot, being an active student in Doom Valley.
  • Secret-Keeper: Even after deducing Petra was once a boy, and still thinks like one, she doesn't go spreading it around. She's aware Petra's got way too much on her plate without having to worry about the girls who are friends and roommates turning on her.
  • Spotting the Thread: She deduces that Petra was once a boy turned into a girl against her will, but doesn't hold a grudge for Petra keeping quiet about it.

     Ivy 
Ella's official bodyguard, and pet werewolf.
  • Animal Jingoism: Being a werewolf, she reacts poorly to Petra's new Cat Girl form. Ella has to order her not to chase Petra around.
  • Blood Knight: She's extremely aggressive and violent.
  • Lazy Bum: She's only interested in three things, fighting, eating and sleeping. She works for Ella in return for food and help with her homework.
  • My Species Doth Protest Too Much: Apparently, sapient werewolves like herself are rare. The werewolves that inhabit the forest near Doom Valley are all mindless beasts, and Ivy herself is only barely capable of understanding social conventions despite being raised by humans.
  • Our Werewolves Are Different: She looks more human than wolf and acts more like a cat than canine, but still responds to a dog-whistle.
  • With Friends Like These...: When the coach of combat class just summarily decides to make Petra the living target dummy, after the crazy cat-girl who volunteered wound up taking an unwitting swim in a lava lake, Ivy rips Petra's throat off. At least it was quick...

     Calcium 
A dwarf that joins Ella's friendship circle.
  • In-Universe Nickname: Her full name is Calcium, per her native race's custom of being named after minerals, but she prefers to be called Calci.
  • My Species Doth Protest Too Much: She's an outlier among the dwarf people as she's got no talent for the forge. In fact, her tribe recommended her to focus on alchemy.
  • Our Dwarves Are Different: While both genders have beards as is the case in most fiction, in this story, dwarves collectivists, who as toddlers are put in groups to be watched over by a few caretakers. As they age, they get placed into smaller groups and are taught to do jobs that best suit them. They're also named after minerals and rocks.

     Naomi 
One of the first girls to befriend Petra during the key free-for-all, and who managed to hold on to her room key.
  • Culture Clash: Regardless of her family's peculiar sense of "honor," forcing her into Doom Valley's warrior program, she's a very girly-girl and just can't understand why Petra isn't appreciative of being constantly dolled up.
  • Did Not Think This Through: She puts so much emphasis on dolling Petra up that she put Petra into her best dress. Petra herself points out how she and clothing don't seem to get along. Pale-faced in terror, Naomi agrees that's a very good point and goes with something easier to replace.
  • Honor-Related Abuse: Her father forced her into Doom Valley "to regain the family honor," choosing the "fighting and leadership" program. And to make it all worse, "the family honor" refers to the guy having failed out of Doom Valley.
  • Sins of Our Fathers: She was sent to Doom Valley because her father failed out of the academy.
  • With Friends Like These...: When Petra was forced to be a live practice dummy, rather than make it quick with a stab to the heart, Naomi "got nervous and missed" five times. That was a slow and gruesome death.

     Clarice 
Another of Petra's first friends in Doom Valley.
  • A-Cup Angst: Clarice frequently gets annoyed and embarrassed by her small chest. When Petra gets larger breasts due to a prank, Clarice laments not being there to get dosed with the same gas.
  • Height Angst: She is the smallest person in the group, in height and measurements. She doesn't complain about it a lot, but how she acts makes it clear this is a sore spot for her.
  • With Friends Like These...: Clarice is the one who pushes hardest for Petra to play the honeypot in their various plots, much to Petra's misfortune and humiliation.

     Garth 
One of the boys that wound up being roped into the gang when the senior student who was supposed to orient Ella's clique bailed on them due to Ella being unwilling to play by her rules. He has an unrequited crush on Petra.
  • All Love Is Unrequited: He has a crush on Petra, who not only isn't into boys, she is too traumatized and on edge to consider romance, at all.
  • Big Damn Hero: When Barbarina is about to do some very painful things to Petra during a chaotic food fight, Garth, who is a middling wizard with no fighting skills, tackles the much stronger girl, freeing his friend. He runs away seconds later along with Petra, he's brave not an idiot.
  • Crazy Jealous Guy: Though he is at least decent about it, he takes Rocky developing a crush on Petra and joining the group because of it poorly.

     Blood Wing 
A half fairy, half succubus that greets Ella in chapter 2 looking for allies and minions.
  • Axe-Crazy: As is almost immediately evident, she's quite unhinged and prone to violence, but she at least has enough self-control that she can follow the rules of Doom Valley and hold a civil conversation.
  • Blood Knight: There's nothing she loves more than a good fight.
  • Hot-Blooded: She is very impatient and irritable, with a tendency to act first, think second.
  • Non-Human Humanoid Hybrid: She's half fairy and half succubus.
  • Loophole Abuse: When the magic class is learning demon summoning, she summons a demon...her mother, the succubus, and asks her to bring lunch, since that's the Exact Words of the assignment.
  • Smarter Than You Look: She comes across as nothing more than an impatient hot-head who can't think further than "Blood Wing—SMASH!!" but when facing off against Michael's alchemical concoctions in the defense of Petra, she asks Petra to use the miscast [Force Bubble] spell to get past his defenses, which ends up blasting him right into the feet of Lady Plague who was at the end of her rope with him and his antics.
  • Take Over the World: Her stated goal is honoring her fairy father's plan to take over fairy lands as the first step in taking over the planet.
  • Too Important to Remember You: She cannot remember Petra's name. So she usually ends up calling her "Ella's friend".
  • Unskilled, but Strong: She's got immense magical power and potential, something she loves to boast of, but she has almost no control over it. Something her and Petra's magic teacher calls her out on.
  • Villain Takes an Interest: She immediately takes an interest in, and a liking of Petra when the latter, wisely, asks "how can we be of use to you?" when Blood Wing and Ella were negotiating a potential alliance.

     Rocks for Brains 
A half-giant that used to be Victor's friend, but he turned on Victor after getting tired of not only cleaning up after the guy's many mind-control atrocities, but setting him up to be the instrument of Petra's murder when a lackey threw Petra's resurrection pin in a lava lake during class. The primary reason is that Petra accidentally used the mating customs of his tribe by having a boulder fall on his head as she desperately tried to avoid the unwittingly homicidal charge.

     Monster Under The Bed 
A monster that lives under Petra's bed. It's a great listener and makes wonderful cookies and tea.
  • Bigger on the Inside: It lives under Petra's bed in a somewhat cramped room, but there's enough room for it, Petra, a kitchen, and other things.
  • Did We Just Have Tea with Cthulhu??: It's introduced having tea and cookies with Petra. It doesn't speak, but it listens to her woes, and tries to encourage the poor girl as best it can.
  • Living Emotional Crutch: Second only to Ella, it's the being Petra runs to when they want to curl up into a ball and hide.
  • Starfish Alien: It's not described in great detail, but it has ten fingers on a hand that feel like bones covered in old, dusty silk. It also has an elephant like trunk, enormous droopy jowls, a lip-less mouth full of sharp teeth, grey eyes, and it can change color.

Enemies

     Michael 
Another student that came from Peter's home town. On the carriage ride over, he feeds Peter a drugged chocolate bar that turns Peter to Petra and later "pranks" his victim with candy doped with other drugs to make Petra an even sexier woman against her will, but still not satisfied ambushed Petra again and used alchemy to fuse her legs to the ground and planned to feed her an amnesia potion, so she'd wind up in potentially lethal detention. He winds up regretting the last part.
  • All Men Are Perverts: His first act in the story is turning Peter into a girl with drugs and using hypnotic suggestions to try and make the new woman madly in love with him. He regrets it when Petra is given the green-light by the teachers to retaliate and beat the snot out of him for three minutes, with Sir Grieve even giving Petra pointers on how to make it hurt.
  • Bitch in Sheep's Clothing: He first appears to be a sympathetic fellow victim of neglectful parents who shipped him off to Doom Valley, pointedly ignoring the dangers, but is actually a willing student who plied Peter with sympathy to make the boy his latest unwitting test subject.
  • Card-Carrying Villain: Once he's drugged Peter, he doesn't bother to hide that it was all For the Evulz, and he really didn't have a good reason to use a gender-swap potion without informed consent.
  • Hoist by His Own Petard: His plan to force Petra to be late for class is what results in him being brought to task and sent to detention, sentenced to wash down zombies. Considering he's next seen turning grey and having a bandage on his hand with magical seals, this apparently didn't go well.
  • Insane Troll Logic: He protests that Petra shouldn't call being gas-bombed by an alchemical potion which made her breasts and hips bigger, to the point she needed new clothes again, an attack because he knows several women who were willing to pay well to buy the same alchemical agent he used for its cosmetic properties. It's only when Lady Plague confronts him with the fact that he literally fused Petra's legs to the ground with his "pranks" that he realized he didn't have a logical leg to stand on.
  • Laser-Guided Karma: He schemed to try and force Petra to be late for class so she'd be sent to potentially lethal detention. He winds up going to detention instead.
  • Moral Myopia: He has the gall to see himself as the victim when Peter, turned Petra, retaliates for being drugged in the first place.
  • Nice Job Fixing It, Villain: The fact that he turned Peter into Petra is probably the biggest reason our protagonist survived the first day of school as that put Petra in touch with Ella, with the two becoming fast friends.
  • Wants a Prize for Basic Decency: He expected gratitude for the unwilling gender-swap in the form of hugs, kisses, and other stuff, and was truly flummoxed that Peter wasn't giving him any, even with the use of many, many post-hypnotic suggestion trigger phrases.

     Barbarina 
A female orc who is one of the first school bullies Petra meets in the girls dorms, and one of the two who demanded Petra's room key during the Secret Test, under threats of violence. Trapped between two bullies, Petra takes a third option and auctions her room key, winner Ella, who then takes Petra as a room-mate. Barbarina has hated Petra ever since.
  • Barbaric Bully: When she makes threats of violence, even death threats, they are always serious and she never hesitates to carry them out. All for the sake of beating up and pushing around people she sees as inferior to herself, enforcing her will, and for kicks.
  • Creepy Souvenir: She scalps everybody she kills and puts the scalp on her own head. It is unknown if this is a tribal custom or just a personal quirk.
  • Hair-Trigger Temper: She loses her temper with ridiculous ease. In chapter 26, Petra jumps back to avoid getting hit by a boulder in the mess hall, bumping into her by accident. Her response is to come at Petra with lethal force for spilling her soup.
  • Misplaced Retribution: When she can't get at the target of her rage, for any reason, she beats up whoever is nearby.

     Victor 
The second of the major antagonists to start something with Petra and friends.
  • Charm Person: His favorite way to abuse his psychic powers is to make himself irresistible to either gender, romantically for women, hero-worshipping variety for boys. It failed on Petra because when he tried to make her romantically infatuated, Petra rebelled because she prefers girls. When he tried the "admire me as cool" approach, after barging in the girl's locker room, Petra was enraged with envy and kneed him in the groin, and then escaped.
  • Disproportionate Retribution: In a Serial Escalation way. When Petra realizes he's trying to mind-control Ella and smacks him upside the head, he goes for his sword, which prompts Petra to beat him down until he stops moving so she doesn't wind up dead. He responds to that by trying to mind-control Petra again, and mind controls Garth to try and have the both of them go at each other like rabbits in heat in the school's mess hall, during lunch. When Petra foils that plan by refusing to be mind-controlled, kneeing him in the groin so she can escape, he retaliates by trying to murder her in their next Combat Training course, by having her [Ressurrection pin] thrown into a lake of lava and then prompting Rocks for Brains to "accidentally" kill her, permanently.
  • Hoist by His Own Petard: His attempts to mind control Petra are directly responsible for screwing him over, twice. With the last attempt turning Rocks for Brains from friend to foe, and without the Half-giant watching his back, everybody he's screwed over is coming at him for payback.
  • Laser-Guided Karma: Petra learns to never, ever piss off Ella, when she sees Victor being the target of a "who can get to him first, and who worst" competition in the chapter labeled "My first day as a cat girl" with the afternoon having all the competitors going for "Double or Nothing." while Ella just happily eats her breakfast, not even looking his way. All as a result of Victor trying his hand at mind-control on her and trying to murder Petra, one of Ella's closest friends.
  • Moral Myopia: He sees himself as the victim of Petra's "injustice" because she just refuses to be mind-controlled by him, and refuses to let herself be killed for the unjust "affront."

     Reginald from The School of Righteousness and Honor 
Petra's counterpart in the "find the gold idol" test.
  • Black-and-White Insanity: As far as he's concerned, every last student of Doom Valley Prep School is irredeemably evil and must be slain, even if they want to repent and transfer to The School of Righteousness and Honor. He doesn't even care if they were dragged there kicking and screaming, the fact that they were ever students is all the "proof of evil" he needs to condemn them.
  • Good Is Dumb: He genuinely wants to protect the innocent, help the helpless, and fight evil wherever he finds it, but he's a self-righteous moron who can't see moral shades of gray, and never knows when to call it quits should he face impossible odds. During the exam, Petra uses a diversionary tactic to have a tribe of goblins attack him while she goes after the idol to end the exam as quickly as possible, figuring he'd retreat the moment he found himself over his head. Instead, he just keeps swinging while calling her name, searching futilely in the wrong direction. She has to go and rescue him, but he immediately feels insulted for the rescue and tries to murder her "for leading him astray."
  • Holier Than Thou: His most annoying trait is that he just will not stop bragging about how righteous he and his entire bloodline are.
  • Lawful Stupid: He's adherent to the more noble aspects of his school, even when it's absolutely suicidal, would make no difference, or at worst, make everything and everyone worse off.
  • Never My Fault: He spends 6 hours boasting of his "noble" bloodline and pedigree, never letting Petra get a word in edgewise. When the exam is over, with Petra's clear victory over him, and saving his life to boot, he loudly proclaims that she was trying to seduce him to taint his pedigree. When Petra calls him out on that, he draws is sword and tries to kill her, right in front of the three top teachers of Doom Valley Prep School WHILE INSIDE THE PREP SCHOOL, and still doesn't realize what he did wrong when his own top teachers chew him out.
  • Not Good with Rejection: When Petra rebukes his one-sided delusion that she was hitting on him, he comes at her with a sword.
  • The Paladin: Deconstructed. He fights for the forces of good, wields a holy sword, and attacks with light-based or holy magic, but he's a Good Is Dumb Lawful Stupid fanatic who can't see shades of grey and will respond to any slight against himself with straight-up murder while thinking he's righteousness incarnate.
  • Pure Is Not Good: He loves to brag about how "pure" his bloodline is, generation after generation of paladins and holy knights, but he's so self-righteous that he will murder an unarmed woman when she refuses to play along with his self-delusion that she was trying to seduce him.
  • Stay in the Kitchen: His stock with Petra plummets when he utterly refuses to let her defend herself from a goblin horde with a scavenged club, even after she demonstrates she can carry her own weight, instead "protecting" her by slamming her into a wall over and over again.
  • Too Dumb to Live: He comes at an unarmed and unarmored Petra, who is not a threat, with his holy sword while at the grounds of Doom Valley Prep School and right in front of three of the top and founding teachers. They would have been in the legal and moral right to kill him if they wanted. For unstated reasons, they instead teleport him back to his own school, where his first respond to an enraged "do you realize what you did wrong" is to go "It's all her fault!"
  • Ungrateful Bastard: Petra doubles back and rescues him from a swarm of goblins at incredible risk to herself, despite having no obligation to do so. How does he responds? By calling her unspeakably evil, insulting her by stating she was trying to seduce him to taint his "noble" bloodline, and coming at her with a sword when she calls him out on his one-sided delusion that she's in any way romantically interested in him.
  • Unwitting Pawn: Petra uses him as an unwitting meat-shield to survive the goblin nest dungeon their respective schools teleported them into.

Teachers

     Sir Drago 
A lizard folk who is the head teacher of alchemy and potion making.
  • Commonality Connection: He openly praises Michael for using a gender-changing potion on Peter without consent, and promises an easy A if the boy can up the success rate of the transformation potion from 40% to 60% by the end of the year, when the failures are, as Michael puts it, "an interesting collection of bugs and fungus."
  • No Sympathy: So what if your prospective classmate switches your gender without permission, calls you stupid because he fed you drugs without your knowledge or consent, and brags that the drugs in question only have a 40% success rate, with the failures polymorphing the victim into some kind of bug or fungus? Not his problem, and you should have known better.
  • One-Shot Character: He appears in chapter 2 and is never seen again.

     Lady Plague 
The head teacher of the magic division and dean of the lady's dorms.
  • Armor-Piercing Question: When Peter, now Petra, understandably protests being sent to the girls' dorms, Lady Plague asks "Do you feel comfortable in the boys' dorm as you are now?" Petra takes a quick look at the line-up of male students, and responds "Okay. That's a good point. A very good point." and reluctantly follows Lady Plague to the girls' dorms.
  • Black Eyes of Evil: Her sclera are solid black, and she is a notorious villain.
  • Blaming the Victim: She calls it "a good lesson" that Peter was turned into a girl by having gender-changing and mind-control potions slipped into his food, and it seems to be an endemic character trait as she later condemns the girls in the dormitory who were beaten black and blue to have their keys stolen for not being strong, clever, or underhanded enough to mount an effective resistance.
  • Crime of Self-Defense: Justified. In her backstory, she legally set up a mage tower and laboratory in unclaimed land. A nearby king got the "brilliant" idea to try and procure her services forcefully by later claiming the tower was built in his territory and she'd either have to serve in his armed forces or pay exorbitant taxes. He sent an army at her in response when she refused. Her response was to unleash a magical plague called "The Walking Death" which annihilated the army and kept going, unleashing a Zombie Apocalypse. All the other countries, plus all the gods and demons of the world, had to join hands and go completely scorched earth to stop the spread. She wound up with a huge gods and demons placed bounty on her head, but is too strong for anyone who tried to collect it to come back alive...
  • Dramatically Missing the Point: She glares and objects when Peter complains of getting gender-bent against his will by asking "you have problems being a woman?" with a nice Death Glare on the side, while ignoring the fact that Michael, the one guilty of the act, is openly proclaiming that he only sees women as sex toys right in front of her.
  • Harmless Electrocution: She primarily uses her lightning magic like a taser, shocking unruly students into compliance.
  • Right for the Wrong Reasons: She does condemn the bullies that beat up some incoming freshmen and took their room keys, forcing the school to put them in a communal barrack, putting the bullies in a different communal barrack themselves, but this has nothing to do with the bullying. She's just taking them to task for listening to a disembodied voice that went contrary to the ground rules of the Secret Test she and the other teachers put the incoming students through at the start of the term.
  • Shock and Awe: She's shown primarily using lightning magic.
  • Villain Has a Point: Prone as she is to blame the victim of bullying, when she's got Blood Wing, Michael, and Petra in her office, discussing the most recent, and last, of Michael's "pranks," she proclaims that Petra must get stronger or she'll be a liability to her allies or employers. Petra agrees and does her best to live up to Lady Plague's expectations.

     Sir Grieve 
The head of the combat arm of the school.
  • Actually Pretty Funny: He laughs at Petra retaliating to Michael's gender-swap and attempt at mind control by kneeing him in the groin and beating him down, even going so far as to give Petra a good three minutes to vent her rage by kicking the creep while he's down.
  • Black Knight: He's in head-to-toe platemail that's painted black, wields a massive claymore, and is the lead teacher of the combat division.
  • Blaming the Victim: He condemns Petra and Rocky for "making a mockery of his class" and sentences them to be punished "for their stupidity", once Rocky's out of the hospital as a result of a bad reaction to the potions Petra pinched from the infirmary. He does this not because Petra and Rocky were busted for stealing (which is actually encouraged as long as you don't get caught), but because the upper year students fought among themselves when Rocky and Petra were disabled by mislabeled stolen potions.
  • Disappointed in You: He reveals during the second day of detention that he's not mad at Rocky and Petra because the tracking class he had them "volunteer" to test their tracking skills were fighting each other over them. No, he's upset that Rocky and Petra took themselves out with mislabeled potions that were stolen from the school clinic. And when he's disappointed, that's when he stops being nice.
  • Facepalm: When Rocks for Brains throws a boulder at Petra in the mess hall in chapter 26, per his race's mating customs, thanks to an Accidental Proposal resulting from Victor's Make It Look Like an Accident murder gambit, Sir Grieve rubs his helm with his gauntleted hand as if he was trying to nurse a migraine, with predictable results.
  • Icy Blue Eyes: In chapter 41, he and Petra get into a staring contest after Petra calls him out on sending her and Rocky on a Suicide Mission to collect a Mock Hydra's egg. Petra actually got to see inside the visors of his armored helm and describes his eyes as glowing with an icy-blue fire, to demonstrate how cold and calculating he is. He then goes on to demonstrate that he is as ruthless as he appears by sending her on that mission, alone, while giving Rocky a free pass on that day's detention.
  • Licked by the Dog: After the events of the chapter marked "Deal With a Demon," he coaxes a hatchling mock-hydra off Petra's arm with a caress and a whistle. The beast flutters over to him and curls up against him, purring. Pleased with his new pet, he tells Petra to go to the nurse to get cleaned up and that detention is over, half-way through.
  • Reasonable Authority Figure: He may be ruthless, but he is not heartless. In the chapter labeled "A Deal With a Demon," Petra returns, not only with an egg, but also a Mock Hydra hatchling attached to her arm. Since this is Petra going way above and beyond, he calls off the rest of her detention with a hearty "Good Work," sends her off to the nurse to get patched up, and makes the Mock Hydra hatchling his new pet.
    • Earlier he also explained why Petra and Rocks For Brains were getting detention in slow, simple terms to ensure the half-giant would understand what he'd done wrong and not do it again. For a teacher that teaches villainy and murder, who is willing to send students on suicide missions, that's pretty nice of him.
  • Villainous Valor: Sure, he may have a betting pool going with the other teachers on when not if Petra will wind up taking a permanent dirt-nap, but he's not going to actively make that happen if he can help it. When Reginald came at an unarmed and unarmored Petra, after the survival test was over, he comes to Petra's rescue, shatters Reginald's magic sword and slams the guy's empty head into the ceiling to try and turn his brain into the "on" position before sending him packing. Reginald not only doesn't learn his lesson, the lout sees Petra as the cause of all his problems and wants revenge.

     Mage Malacoda 
The magic teacher for the first years.
  • Badass Finger Snap: He always cancels Petra's magical mishaps with a snap of his fingers.
  • Beleaguered Bureaucrat: He tries so very hard to teach Petra magic, and he is a good teacher, but he's at his wits end with her constant, and dangerous, screw-ups, and there's no point in disciplining Petra either since the screw-ups are entirely accidental.
    "Student Petra, you've somehow managed to make a dispel shield that amplifies the spell sent at it!"
  • Hidden Badass: Though it's yet to be shown, he has enough magical oomph that he forces an eldritch entity to release one of his students just by verbal command and foot-tapping alone.

     Angel Slayer 
A female orc in charge of the combat training course.
  • Sadist Teacher: She has an on-screen habit of using students, even those who haven't broken any rules, as living target dummies, and if they object, threatens to have them be dummies with their resurrection pin on, or off, their choice.
  • Training from Hell: Let's just say surviving the entirety of a semester in her class, with all your limbs attached, is a minor miracle.

     Subterfuge teacher Bob 
The one teacher Petra inherently likes and show also serves as her guidance counselor.
  • Assassin Outclassin': He, in front of the entire class, nails an assassin sent at him with an invisibility cloak, wielding nothing more than a sharpened pencil!
  • Cool Teacher: He and his class are a lot of fun and Petra enjoys his teachings.
  • Once Killed a Man with a Noodle Implement: He took down an assassin with a sharpened pencil!
  • Only Known by Their Nickname: Bob is not his name. He just uses it because the normal mortal can't pronounce his actual name.
  • Tom the Dark Lord: One would never expect some harmless-looking guy with a name like "Bob" would be so badass that he could detect and take out a kingdom's elite assassin in seconds with nothing more than a sharpened pencil!
  • Voluntary Shapeshifting: Petra once comes to class and is asked by what looks like a pre-teen girl if her pencil is sharp enough. Petra almost touches the pencil before remembering where she is and provides a piece of paper to test the sharpness. When the paper shreds at a touch, Petra goes "that pencil looks sharp enough to kill someone." At the confirmation, the "little girl" transforms into Bob and skewers an invisible assassin with that very same pencil, pinning the guy to the wall through his shoulder.

     Ms. Parch 
The history teacher and the goddess of written history.
  • Cool Teacher: Surprisingly, she makes studying written history fun.
  • Gods Need Prayer Badly: She gives her students lots of tests and papers to write, while actively encouraging them to pray to her.
  • Physical God: She is an active goddess who manages all of written history.
  • Stern Teacher: She may make her class enjoyable, but she is also very strict and doesn't tolerate apathetic or disruptive students easily.

Others

     Peter's parents 
The pair of idiots who sent Peter to Doom Valley Prep School without clearing it with him first, thinking nothing wrong of their actions.
  • Abusive Parents: While we don't know what the rest of Peter's life was like under their care, the fact that they see nothing wrong with sending their only child to an academy notorious for killing off its students, and pooh-poohing his objections when he learns of it, means they can't be anything else than abusive.
  • Appeal to Worse Problems: When Peter retorts to their assertion that going to Doom Valley is the best thing since sliced bread by pointing out he'd have better odds playing in traffic while waving a dagger around, they retort "Oh, it's not that bad, it used to be worse, but it's only 20% of the class that dies now, most everyone else just comes back having endured some transmutation. Heck, your cousin came back as a newt 5 years ago and just turned back into a human, though he's still a little bit odd..."
  • Just Think of the Potential!: They try to justify sending Peter to Doom Valley by going "you could become the next Evil Overlord with a valid plan to Take Over the World!"
  • Lethally Stupid: In chapter 4, Lady Plague gloats that these two dimwits didn't ask many questions and just took her advice for what curriculum to put Peter in at face value, even though they both knew this is a school to train villains. She can only giggle at how silly such a careless way of thinking that is.
  • Obliviously Evil: They genuinely believe they're doing Peter a favor by sending him to Doom Valley, and are disappointed in him that he just doesn't see it that way.
  • Right for the Wrong Reasons: The way they ambushed Peter with enrolment at Doom Valley was atrocious and deserves scorn, but on day two, it's obvious Peter/Petra would not have been a good contender for The School of Righteousness and Honor. Petra did quite a few morally dubious things during the survival test, and continues being ... pragmatic with her moral code. At best, Peter would be a pragmatic anti-hero, but more likely would be entirely unscrupulous, as Petra is very, very comfortable with "it's not a rule if I don't get caught breaking it."
  • Skewed Priorities: Just before they send Peter off on the carriage to go to Doom Valley, they strongly caution "don't get killed as a result of a teacher's discipline. We won't be getting a refund of your tuition if that happens!"
  • Unnamed Parent: Their names are never mentioned.

     Brooke Marwood 
An aspiring mage that thought it a swell idea to pretend being a girl to infiltrate the girls dorms and even took Petra hostage in the attempt when the illusion wore off. The monsters under the stairs were not fooled.
  • Did Not Think This Through: His entire "plan" such as it was, was doomed to failure. Using an illusion spell with a time limit to enter the girls dorms, while passing both monsters and staff who have a list of names authorized to be there, and all the faculty watching via magic crystal? And answering with his real name when asked and it doesn't match the list of authorized students?
  • Eaten Alive: When the monsters grab him and ask for his name, he answers "Brooke Marwood." The monster responds with "Not on the list" and throws him into its maw, whole.
  • Protection Racket: He grabs Petra when she realizes he's not a girl and demands to be allowed access to the girl's dorms, promising to keep her safe. The monsters grab both of them and screen them by name against the list. He gets eaten, Petra is let go.

     Cafeteria staff 
  • Cuteness Proximity: When Petra sports a cat-girl form, the cat-woman staff-member happily waves her over, cuddles her, and then gifts her a cat-person delicacy, hogtied live mouse, and Petra states that it does smell appetizing, but can't bring herself to eat it. Ivy, on the other hand, appreciates the free meal. Petra gets a serving of scrambled eggs so she doesn't go hungry.
  • Obstructive Bureaucrat: No matter what Petra orders, they just respond "All OUT!" without even bothering to check. A throw-away line indicates that maybe when Lady Plague just summarily changed Peter's name to Petra, the change didn't filter down to Petra's food allotment. Either that or Peter's parents didn't pay for the school food as part of the tuition in the first place. Then again, maybe the staff are all just jerks. The real reason remains a mystery, and even a word from Bob, master of the school of subterfuge, acting as Petra's guidance counsellor, doesn't sway them, except to just hand Petra a tray of barely edible trash and say "gift from the school, NEXT!"

    Fate 
The personification of Fate.
  • It Amused Me: Seems to be her entire reason for choosing Peter as her newest chew toy.
  • Lady Luck: While she's in control of fate, she appears to also be the personification of luck, at least when she wants to have some fun. This is shown with her dice for eyes, and causing extreme unluckily lucky situations. The author has stated that she shifts the odds for certain things to see how her chew toy will deal with the newest dangerous or humiliating situation, and to ensure Petra remains interesting. He's also compared her meddling to weighting the dice a little.
  • The Chew Toy: She isn't the chew toy, she makes them for her amusement.
  • The Dreaded: While not actively feared, no one will tell Petra what's going on because they don't want to risk being punished. It seems Fate doesn't like people spoiling her fun.
  • Wingding Eyes: The one time she's seen, at the very start in a dream, her eyes are dice.

     Nyla 
An upper classman who happens to be one of Ella's siblings.
  • Living Aphrodisiac: Just smelling her perfume puts Petra into estrus to the point she soaks her clothes.
  • Master Poisoner: Ella whips out antidote pills for the group to eat now because they all shared the same air as Nyla. While deadly poison is out...
    “Probably not. But projectile diarrhea and vomiting, being paralyzed for 24-hours, an hour long waking night terror, itching so badly you tear your skin, acidic sweat to melt your clothes, making you smell like a dung golem for a week, all of those are on the table. She likes to keep people on their toes.”
  • Who Needs Enemies?: That list Ella mentions above? That's what she does to people she likes.

     Tanya 
One of the two first bullies, along with Barbarina, that Petra meets in the girls' dorms. She acts as if all the other first-year girl students should be honored if she decides to boss them around.
  • Animal Companion: She walks around not just with a magic staff, but a living tiger.
  • Be Careful What You Wish For: She encounters Petra, Naomi, and and Clarice outside a door Petra just realized is clearly not the game room because, by sheer instinct, Petra was able to shut the door before some tentacled monster grabbed her and dragged her inside. When Petra's circle of friends try to warn her, this girl cuts them off and insists on being allowed to go inside, or else. Petra and crew complies. Cue this arrogant twit and her pet being dragged into the room and an off-screen fight that has the tiger flee for its life with chunks of fur missing, and the girl having to be rescued by school staff.
  • The Bully: Like Barbarina, her first meeting with Petra was a demand to do as she says or face violence.
  • Fatal Flaw: Arrogance. She is completely and utterly convinced that she's the bee's knees, and all the female freshmen are so beneath her that she has no reason whatsoever to listen to a word they say, unless it's "yes, Mistress" when she gives a command. Naturally, this bites her in the butt, literally, when she orders Petra and crew to clear her way and refuses to listen to their warning, walking right into an infestation of some Tentacled Terror.
  • Out of Focus: She's rarely seen in the story because she apparently has no overlap in class schedules with Petra.

     Lil 
The Lillin that traded shapes with Petra in exchange for helping her find the Mock Hydra's nest.
  • Deal with the Devil: She trades shapes with Petra, due to her shape being "too well known" in exchange for helping Petra with her detention task of getting a Mock Hydra egg, by helping Petra find its nest.
  • A Dog Named "Dog": She's a Lillin named Lil.
  • Exact Words: She ditches Petra after showing her where the Mock Hydra nest is because she never promised to actually get the egg for her, just provide general aid.
  • Laser-Guided Karma: For keeping quiet about the pitfalls of trading a cat-girl shape to a Lillin shape, only revealing the drawbacks by accident, and then after the trade was made, she apparently winds up catching the eye of Fate for taking on Petra's form. Oops.
  • You Didn't Ask: She doesn't bother to tell Petra that her Lillin form is vulnerable to sunlight, except by accident when asking if the cat-girl form she just picked up is also vulnerable to sunlight.

     Margo 
Bloodwing's mother.
  • Hot Skitty-on-Wailord Action: She's close to human sized, Blood Wing can even sit on her shoulder, and she's married to a fairy, who is roughly Blood Wing's size.
  • If You Ever Do Anything to Hurt Her...: She gives Petra (Lilin form) a warm hug and whispers that if Petra ever does anything to seriously harm Blood Wing, it won't matter what kind of protection Petra has, she will kill Petra as brutally as she can, her fairy-necromancer husband will take custody of Petra's soul, and that soul will be tormented for the next millennia.
  • Mama Bear: She is very, very protective of Blood Wing.
  • Mathematician's Answer: When she pegs into the fact that Petra is Fate's Chew Toy and Blood Wing asks if she's better off being closer to Ella or keeping her distance, the answer she provides is "Yes."
  • Pass the Popcorn: After realizing that Petra's Fate's chew toy and Lil has, apparently, caught Fate's eye by trading shapes, convinces Lil's sister, Mara, to join her with a nice bag of popcorn and a couple of cold brews to sit back, far, far away and watch the fireworks.

     Mara 
Lil's older sister.
  • Actually Pretty Funny: When she realizes Petra's telling the truth about trading shapes with her sister Lil, and realizes Petra's Fate's chew toy, she grabs her sides and rolls on the ground laughing.
  • Big Sister Instinct: She first thinks she's talking to Lil when she meets Petra, but when she learns Petra is not Lil immediately presumes the worst and gets aggressive. It's only when Petra manages to convince her that she and Lil traded shapes willingly, and she smells the mark of Fate that she lets Petra off the hook.
  • Pass the Popcorn: When she's considering her options with Margo, she can't decide if she wants to warn Lil, or drink beer and eat popcorn far, far away. She ultimately decides to do the latter.

     Kai 
Ella's older brother.
  • Alchemy Is Magic: He created the cat girl potion for Petra, which drastically transformed her body in a few minutes.
  • Amazing Technicolour Population: He's purple. Why he's purple is unknown.
  • Big Word Shout: Upon hearing that Petra has rapidly transformed herself over a period of two weeks, he shouts, "TWO OR THREE DAYS!"
  • You're Insane!: When he hears how often and how quickly Petra has transformed herself, he exclaims, "Are you insane?!"
