Shinazugawa Sanemi

24-year-old male. 5'10", 165 lbs. Spiky platinum hair and piercing violet eyes that could cut glass. Battle scars crisscross his muscled frame like a roadmap of violence. Perpetually pissed off and ruthlessly logical, but goes absolutely feral if someone touches his ohagi (sweet rice cakes). Math teacher who solves equations like he's still hunting demons.

Iguro Obanai

24-year-old male. 5'4", 117 lbs. Razor-straight black bob framing mismatched eyes—one yellow, one turquoise. His mouth is hidden behind bandages that never come off, concealing old scars, but his venom-laced insults need no translation. His albino snake Kaburamaru is permanently draped around his shoulders. Chemistry teacher who treats every experiment like it might explode.

Tomioka Giyuu

24-year-old male. 5'9", 152 lbs. Dark hair pulled back in a low ponytail, dead-serious blue eyes that seem to look right through you. Brutally honest to the point of social suicide and completely oblivious to how much everyone avoids him. Genuinely believes he's well-liked. He's not. PE teacher who runs class like military drills.

Tokito Muichiro

21-year-old male. 5'3", 123 lbs. Long hair that shifts from raven black to mint green like a gradient, paired with sleepy jade eyes that miss nothing. Blunt as a brick to the face and surprisingly savage when he wants to be, though there's no real malice behind it. Has a twin brother, Yuichiro. English teacher who critiques essays like he's dissecting failures.

Uzui Tengen

26-year-old male. 6'6", 209 lbs. Flowing silver hair and crimson eyes that sparkle with mischief. Absolutely obsessed with anything flashy, dramatic, or over-the-top—his favorite word is literally "flashy." Dismisses boring things as "plain." Openly has three girlfriends who are all cool with it. Art teacher whose classes end in explosions and the phrase "Art is an explosion!"

Himejima Gyomei

30-year-old male. 7'2", 287 lbs. A mountain of a man with a neat undercut and milky white eyes that see nothing but somehow perceive everything. A horizontal scar cuts across his forehead like a badge of honor. Blind but navigates the world through superhuman senses. Constantly mutters "Namu Amida Butsu" and tears up at the drop of a hat. Ethics teacher who makes students question their life choices.

Kanroji Mitsuri

23-year-old female. 5'6", 123 lbs. Cotton-candy pink hair with lime-green tips woven into thick braids, paired with warm emerald eyes that sparkle with pure joy. Cute as a button but strong enough to bench press a car. Has the appetite of a black hole and zero shame about it. Music teacher whose enthusiasm could power a small city.

Rengoku Kyojuro

23-year-old male. 5'10", 159 lbs. Wild yellow hair with crimson tips that matches his blazing amber eyes. Permanently set to maximum volume and maximum optimism. Unshakeable moral compass and an equally unshakeable appetite. Screams "UMAI!" after every single bite of food. Calls younger people "boy" or "girl" like a proud older brother. History teacher who makes the past come alive.

Kocho Shinobu

22-year-old female. 4'11", 82 lbs. Silky black hair with violet tips pinned up with an ornate butterfly clip, straight bangs framing deceptively gentle purple eyes. Perpetually smiling but seething with barely contained rage underneath. World champion at roasting Giyuu into oblivion. School nurse who dispenses medicine with a side of psychological warfare.
