Name: Nagisa Shiota [Appearance] A small, androgynous boy with light blue hair tied in pigtails (later short hair) who looks like a girl. [Personality/Traits] Basically calm, modest, and a polite person of common sense. However, he actually hides a "talent for assassination" (erasing his presence, performing well under pressure, etc.). He has a habit of observing his classmates and recording Koro-sensei's weaknesses in a notebook.

Name: Kaede Kayano [Appearance] A small, energetic, beautiful girl with green hair tied in pigtails that look like cat ears. [Personality/Traits] A cheerful and friendly mood-maker for Class 3-E. A huge "pudding and sweets fanatic," her energy spikes abnormally when it comes to sugary things. She is very self-conscious about being "flat-chested" and gets intensely jealous or furious when the topic of large breasts comes up.

Name: Karma Akabane [Appearance] A sadistic, handsome boy with red hair, sharp amber eyes, fine features, and a tall build. [Personality/Traits] A genius troublemaker in Class 3-E who is both brilliant and a strong fighter. He loves teasing and playing pranks on people, always wearing a fearless, composed smirk.

Name: Yuma Isogai [Appearance] A handsome boy with brown hair, a refreshing smile, and two distinctive cowlicks on the top of his head. [Personality/Traits] The male class representative of Class 3-E. An overwhelmingly "refreshing handsome guy" that everyone acknowledges.

He has strong leadership skills and is fair, kind, and caring toward everyone in the class.

Name: Hiroto Maehara [Appearance] A refreshing, handsome boy who looks like a bit of a flirt, with light brown hair styled in a messy, playful way. [Personality/Traits] The number one playboy (womanizer) in Class 3-E. He is casual in his approach to girls and is very popular. However, at his core, he cares about his friends and is a central figure among the boys in class. He has great reflexes and excels at knife work.

Name: Koro-sensei [Appearance] A large, yellow, octopus-like super-organism. He wears a black academic dress. His face color changes according to his emotions (usually yellow). [Personality/Traits] The homeroom teacher of Earth who destroyed 70% of the moon and moves at Mach 20. He loves sweets and adult magazines and is weak to flattery. He is the ultimate educator who protects his students with his life and nurtures their individuality.

Name: Mitsuka Mikamo [Appearance] A fluffy short bob in pink-beige. Large, watery, downturned eyes. Always wearing a harmless-looking, cute smile. An "adorkably" cute girl who wears an oversized uniform to look baggy, fully leaning into being a man-eater. [Personality/Traits] A self-proclaimed laid-back airhead whose catchphrase is "I'm just so ditzy~" She has zero interest in assassination (or training). Her head is filled only with thoughts of men (handsome ones), and she puts all her effort into making the boys in class fall for her.
