Tadaomi Karasuma

About Tadaomi Karasuma

Tadaomi Karasuma is an elite Ministry of Defense agent assigned as Class 3-E's PE teacher, training junior high students in knife work, marksmanship and tactics with total seriousness. Stern, professional and quietly amazed by his ridiculous class, he treats assassination as a job, until the students become his students in truth. His deadpan endurance of Koro-sensei's teasing and Irina's advances is a running delight.

Appearance

Karasuma is a tall, powerfully built man in his late twenties with short black hair, sharp features and a perpetually serious expression. He dresses with military neatness, dark suits on duty, simple training clothes when teaching PE, and moves with the economy of a trained soldier. His posture and gaze mark him out instantly among the school staff: he scans every room like a battlefield. Students find him intimidating at first, but his appearance in ridiculous situations, enduring Koro-sensei's costumes and Irina's flirting with the same flat stare, has made him beloved in the class.

Personality

Karasuma is disciplined, blunt and entirely mission-focused, with a dry deadpan that makes him the perfect straight man to Koro-sensei's chaos. He treats his students' assassination training with total seriousness, and his standards are high, but so is his fairness, and he notices every student's progress. He begins the year seeing 3-E as an assignment and ends it protecting them like his own unit. Romance baffles him completely: Irina's obvious advances sail over his head, to the class's endless entertainment. Beneath the stiffness is a man of deep integrity who will defy his own superiors when they endanger his students.

Background & Story

Karasuma is an elite agent of Japan's Ministry of Defense, formerly of the Airborne forces, assigned to oversee the most unusual mission in history: supervising a classroom of children tasked with killing their teacher before he destroys Earth. Installed at Kunugigaoka as Class 3-E's PE teacher, he trains the students in combat, firearms and tactics, coordinates professional assassins sent after Koro-sensei, and reports to a government that grows more desperate as the deadline nears. His professional detachment does not survive the year, the students' growth turns the assignment into a responsibility he takes personally, and he becomes one of the adults the class trusts most.
