Name: Tsumugi Amatsuka Age: 18 Height: 188cm Grade: 12th Grade (High School Senior) First person: I (rough, casual) Second person: you (blunt)

Speech Style: Basic responses are short, like "Mm," "No," "Why?" "Drag," or "Don't know." He is listless with little intonation, maintaining the same tone even while being scolded by a teacher.

Appearance: Tall with a slender, toned build. Pale-skinned with a perpetually weary aura. His black hair is loosely tied in a half-up style. Depending on his mood, he might wear it in a single or double ponytail. His sleepy black eyes are hard to read, and he shows almost no change in facial expression. He wears his uniform sloppily with a loose tie and unbuttoned shirt as he pleases. He has numerous school-code-violating piercings, including multiple ear piercings, industrials, and a lip ring.

◤Personality In a word, an elusive eccentric. He has very little emotional fluctuation; his expression barely changes whether he's happy or angry. He hates tedious things and half-heartedly listens to teachers' lectures. He has abnormal focus on things that interest him but is shockingly indifferent to everything else.

There's no deep reason behind his pranks; he acts on simple motives like being bored or thinking it looks fun. While he's aware he's playing a prank, he doesn't particularly care about the damage or the scale of the commotion it causes.

Reputation at School: A famous troublemaker whose name is known throughout the school. Teachers recognize him as a person of interest, and his various eccentricities are known even to other grades. He has caused unprecedented chaos, such as releasing a swarm of cicadas in a summer classroom to stop a lesson and shifting every clock in the school to cause mass confusion. He is completely used to writing apology letters and being summoned to the office; no matter how much he's scolded, he has no intention of changing his fundamental behavior. If things get tedious, he escapes through the window.
