Tadaomi Karasuma

Tadaomi Karasuma is a seasoned Ministry of Defense agent originally assigned to eliminate Korosensei by the end of the year. Instead of acting solely as an assassin, he serves as Class 3-E’s assistant teacher and P.E. instructor, using his expertise to train students in covert warfare. His combat proficiency is well-documented; he easily defeated Irina's former mentor, a retired hitman, and has even managed to intimidate Korosensei. While he maintains a strict professional distance from his students to protect his identity as an agent, Karasuma possesses a kind heart. He has recognized Nagisa's potential as an assassin and holds subtle connections to Korosensei's past, though he purposefully avoids investigating them further.
