Tadaomi Karasuma

Tadaomi Karasuma is an agent sent from Japan's Ministry of Defense to supervise Korosensei. In Kunugigaoka Junior High School, he was admitted as an assistant teacher for Phys. Ed. in class 3-E.

Appearance
A dashing young man with silky black hair. Has piercing eyes.

Personality
He is a strict but kind man, though he keeps a distance between himself and the students due to his status as an agent and his own professionalism. He is also extremely dense when it comes to love, but isn't so oblivious that he doesn't figure it out eventually. Even though he comes off as distant, he's not completely devoid of emotion and seems able to express happiness very rarely; most notably, during violent situations.

History
He is well known amongst militaries for his outstanding reputation and is a powerful individual, which he has proven when he easily overpowered Lovro, who is a retired assassin. Akira Takaoka considered him as his rival when he was in military.

Plot
He first appeared to class 3-E announcing Korosensei's deal with the government and their mission to assassinate him before the end of the year. He later became the assistant teacher and P.E. instructor of class 3-E to train the students.

Abilities
Karasuma is a very powerful person. He is at the peak of his physical ability, and is highly skilled in the use of knives and firearms as well as hand-to-hand combat. As revealed by Korosensei, the true reason of his strenght is the "deep rage hidden in his heart". What he refers to by this statement is unknown. He's widely considered the strongest human alive, by both allies and foes alike.

Koro-sensei is his target. Most of the time, he seems annoyed and exasperated by him. Unless they are educating, they don't get along in the slightlest. He seems well informed about his past and motivations, but refuses to talk about them, presumably at Koro's own request. Various students remark that, under different circumstances, they could have become close friends.

Irina Jelavic

Irina is his coworker. Since the start, he's reluctant to hire her, considering her a danger to the students wellbeing. The start couldn't have been worse, as Irina shows absolutely no interest on the safety of the class, prompting Karasuma to tell her to change her attitude or she would be replaced. After she grows fonder of the class, their relationship turns cordial at best. He constantly chides her for her lax attitude and lack of professionalism, as she does the same to him for his stuffiness and extreme distance.

At one point, he becomes aware of Irina's growing affection for him, but he seemingly has no interest on reciprocating it, as he sees their relationship as an strictly laboral and temporary one. He reveals this to her and the students on chapter 99.

Class E
Despite his best attempts at keeping his distance, he grows fond of the class as time passes by. The students appreciate him greatly, but also respect him to the point of fearing him.
