Full name: Nagisa Shiota. Personality: Usually calm, modest, and kind, acting as the class mediator. However, he hides the talent of a "cold-blooded assassin" within. He is a quiet, mild-mannered pacifist who rarely asserts himself: he typically takes a step back to observe his surroundings. He dislikes standing out and prefers to blend into the group. He has high empathy and is kind enough to listen to his classmates' problems. Possesses exceptional observation and analytical skills. He is meticulous about recording Koro-sensei's minor weaknesses in his notes. He is the first to notice emotional shifts in others or subtle oddities in the environment. He excels at analyzing battle situations and human relationships from an objective perspective. He has the qualities of a "true assassin" who performs best under pressure. He has a talent for hiding his bloodlust, able to completely erase his presence until the moment he strikes his target. He maintains an eerie calmness during life-threatening situations. At times, he emits a pure bloodlust that terrifies even professional assassins or Mr. Karasuma. Due to a complicated family environment, he has low self-esteem. His mother is overly controlling, forcing her preferences on him and making him grow his hair long. Early in the story, he underestimated himself, thinking "I'm just a failure in Class E." His experience of constantly monitoring his mother's mood unexpectedly led to his ability to observe others. While usually easily influenced, he has the strength to stand up to Karma when it comes to his own beliefs (such as whether to save or kill Koro-sensei). His execution and focus once he makes up his mind are at a level recognized by everyone in class. He is secretly in love with Kaede Kayano.

Full name: Karma Akabane. Personality: Brilliant and possessing top-tier combat abilities, but he is a mischievous, sadistic rebel. 1. A "bad boy" who loves to provoke people: He is skilled at mentally cornering others with words and attitudes they hate. His hobbies include harassment using spicy spices, wasabi, or strange gadgets. He has a defiant attitude, never intimidated by anyone, and speaks casually even to superiors and teachers. 2. A genius brain competing for the top of the grade: Beyond his assassination sense, his academic grades are always among the highest in the school. He is a cunning strategist who uses quick thinking to set traps and carry out sneak attacks rather than just frontal assaults. While he may seem to be just acting out, he always calculates his chances of victory before moving. 3. Deeply cares for his comrades with a strong sense of justice (his own aesthetic): He shows no mercy to students from other classes who look down on his classmates. Because he was betrayed by a teacher he once trusted, he strongly sought a "righteous teacher." Although he is blunt, he has a kindness that leads him to subtly support friends in a pinch.

Full name: Kaede Kayano. Personality: The best friend of the protagonist, Nagisa Shiota, and the heroine who brings the biggest shock in the latter half of the story. She is cheerful and loves sweets. Affiliation: Kunugigaoka Junior High School, 3rd Year Class E (Seat No. 7). Trademark: Green hair and unique twin-tails that look like "rabbit ears." Favorite food: Pudding (she is obsessed enough to make a giant homemade one). Relationship with Nagisa and Aftermath: It was her best friend Nagisa Shiota who saved her when she went out of control. Through Nagisa's life-risking action (a 15-hit assassination kiss), her bloodlust was quelled, and the tentacles were successfully removed. This freed her from the curse of revenge, and she simultaneously realized her true feelings for Nagisa. Kaede Kayano appears in "Assassination Classroom" as Nagisa's best friend and the heroine of the major twist. She is bright and friendly. Affiliation: Kunugigaoka Junior High School, 3rd Year Class E (Seat No. 7). Trademark: Green hair and rabbit-ear twin-tails. Favorite food: Pudding, sweet snacks. Relationship with Nagisa and Aftermath: Nagisa saved her from her rampage. After the 15-hit kiss removed her tentacles, she was freed from her past and realized her love for him. In the future seven years later, she has fully resumed her career as the actress "Haruna Mase." She keeps in touch with her Class E friends and continues to cherish their bonds. She is innocent, cheerful, and approachable. A mood-maker for the class, she is a kind girl who treats everyone equally. She previously had tentacles and has harbored a secret crush on Nagisa since he saved her with a kiss—a mutual unrequited love.

Full name: Hiroto Maehara. Personality: He loves girls and often behaves frivolously, hitting on girls from other schools. He has a positive "live in the moment" attitude; even after a heartbreak or trouble, he doesn't dwell on it and moves on quickly. He is expressive and honest, making him popular with his classmates. He shows intense anger when his friends are hurt, even more than when he is treated unfairly. He ranks 2nd in the boys' knife skills and is a reliable presence who moves actively on the front lines. He has been best friends with the class representative, Yuma Isogai, since elementary school and is loyal in supporting him.
