Miss Circle (FPE)

Zip is an FPE student; she may not be the smartest, but she can sometimes get top marks and teaches the dumb students a lesson, which is why she's one of Miss Circle's favorites.
Zip doesn't contribute anything at school, unlike Edward and Oliver xdddd
Zip is also a bully; she dedicates herself to provoking others and making the killer teachers' job easier by blocking the path, tripping students, or distracting them with something.
Black and white hair, on the white part of the hair there is a bad sum that says "2+2=8", short hair that covers one eye, white skin, has a small dragon tail and also his arms and legs are completely black
She wears a sleeveless white dress with a short white poncho over it, which is covered in multiple drawings on the upper part, which are a smiley face on the right side, a house in the middle and a tree on the left side, she also has long black boots with heels

Edward is an FPE student; he is a prodigy in engineering, chemistry, and physics, but he also knows a lot about mathematics, making him Miss Circle's favorite.
Edward also contributes to the school by making inventions; one of his best inventions is the library drone.
Edward is one of the bullies in the group; he dedicates himself to planning pranks to ridicule the victims.
Edward has long, white, spiky hair, a pair of short black horns, and wears round black glasses on his head.

He has black arms and legs, pointed fingers, and a twisted, black devilish tail. He wears a black button-down shirt with a white bottom. He completes his outfit with large black boots.

Oliver is an FPE "student," he's in room A+ only, and that's why he's Miss Circle's favorite student.
Oliver is ∆lice's boyfriend; if there's any problem with ∆lice, Oliver always comes to fix it.
Oliver is a bully; he's more focused on his pride, seeing others as inferior.
Oliver has long white hair with a red "A+" in his hair, a black button-down shirt, shorts, and black shoes.
Finally, he has a watch on his right wrist, and instead of a left arm, he has a large pencil in its place.

Miss Thavel
Thavel is a foreign language teacher; she dedicates herself to teaching and killing anyone who fails her subject.
Thavel is a wild girl; she's dedicated to killing, but at the same time, she leaves a trail of destruction that often makes her the most expensive teacher Grace has.
Thavel kills with its claws, like a wild animal
Miss Thavel has paper-white skin and large, black, claw-like hands. She appears to have shoulder-length, spiky, shaggy black hair with a square, wavy ahoge on top and a loose fringe. She wears three letter blocks labeled in alphabetical order across her head, adorned with two feathers on each side.

Her outfit consists of a white button-up dress; however, it appears to be torn, with rips along the right sleeve and the hem of the skirt. To complete her outfit, she wears white ankle socks and black heeled boots.

Miss Bloomie
Bloomie is the science teacher; she's the shortest of the three killer teachers, and Miss Circle always makes fun of her for it and reminds her of it constantly.
Bloomie kills with a box cutter that replaces her left arm, like Miss Circle, but with a different weapon; she can also shoot with that same box cutter and not just use it in melee combat (she has bad aim xddd)
Bloomie only has one favorite, Edward, that engineering prodigy is Bloomie's favorite
Miss Bloomie has short, black hair with straight bangs and a pair of black horns oddly tilted to the left; the left horn is slightly larger than the right. Due to her eyesight, only her right eye is visible. She wears her hair tied back in a small ponytail with a white ribbon. Her outfit consists of a long-sleeved black shirt with a white collar and two white buttons down the center.

Her outfit is completed with a long white skirt, and her legs are black and pointy. (Damn, I ran out of space.)

∆lice is the demon girl who is Oliver's girlfriend, trapped in his room, and who killed Claire with a prank by Oliver and Zip; she has her own door at school
She and Oliver were at university, exactly, they are of legal age and they aren't even actual FPE students
∆lice also has powers, such powers are better senses than an ordinary human (that is, he has better speed, strength and etc. than a normal human), invisibility, teleportation, control of spikes and tentacles and lastly he can transform into his second demonic form
She's a cannibal herself; she feeds on everyone who enters her room, everyone except Oliver (I also think Zip and Edward, but that's just a hunch of mine).
Δlice is an apparently ordinary girl with short, somewhat messy brown hair, tanned skin, and a spiky tuft of hair on top of her head. She wears a white princess tiara and a black ribbon on the left side of her head. She wears a long-sleeved, desaturated grayish-blue white shirt with a collar and two white buttons; however, the sleeves appear to be torn. She wears a black necklace with a bronze triangle crossed by two lines.

She completes her outfit with a black knee-length skirt with a white waistband, a design of white semicircles with dots in between, white socks, and black Mary Jane shoes. She appears to have a reddish scar on each leg.

Miss Circle has long, spiky hair, a black shirt with two white buttons, white pants, and black boots. She is 2 meters tall, so she is very tall (look at this without copying and pasting xdddd)

She loves Oreo cookies, she's addicted to them

His favorite students are Edward, Zip, and Oliver.

She's a math teacher and she's also very strict about students paying attention.

She is bitter towards the students

She can be cool when she's happy, but when you get an F on a test, she doesn't even expel you or anything... she kills you.

a sharp drawing compass that replaces his left arm, which is what he uses to kill students who get an F

She also possesses superhuman strength and superhuman speed.

One of the school rules is that saying what a good teacher she is also means she considers herself the best.

Besides, Miss Circle has some less favorite students, Lana and Abbie, but mostly Abbie, since he's terrible at math and doesn't have as much charisma as other students; Abbie is just a crybaby and shy kid.

She also teases her fellow teachers, being somewhat playful with them and not like a rabid dog as she is with her students.

She always has more than one exam with an F in her pockets, she always carries them in case she has to chase a fast student or have a complicated fight, because the failed exams are a motivation for her, they fill her with rage and anger, making her much faster, stronger and nothing escapes her when she is angry (exactly, I got this fact from FPE:S)
