In the alternate universe set in an RPG world, the students of Kunugigaoka Junior High School are heroes under training and students of Class 3-E are those with bugs, making them weaker than other heroes. They are tasked to defeat Koro-sensei, a octopus-like creature, who intentionally teaches them so they can defeat him one day.


Koro-sensei (殺せんせー, Koro-sensē)
Voiced by: Jun Fukuyama (Japanese); Sonny Strait (English)
Koro-sensei is a Demon King who intentionally offered himself to be the teacher of Class 3-E so they could defeat him someday. He was once a hero who achieved everything and grew bored. Aguri Yukimura from Temple of Trade then offered him a position as a Demon King and the robe he wears gave him the yellow octopus-like appearance he has now. Even after becoming the Demon King, he was still bored since nobody could defeat him, hence the reason he wanted to teach Class 3-E.
Nagisa Shiota (潮田 渚, Shiota Nagisa)
Voiced by: Mai Fuchigami (Japanese); Lindsay Seidel (English)
Nagisa is one of the students in Class 3-E and the main student character. Unlike other students, Nagisa's bug is randomized, and ranges from making his body buffed to turning back the time without erasing anyone's memory. Due to his feminine face and figure, he is able to equip items meant for female characters.
Kaede Kayano (茅野 カエデ, Kayano Kaede)
Voiced by: Aya Suzaki (Japanese); Monica Rial (English)
Kaede is one of the students in Class 3-E who is often seen with Nagisa. She loves pudding and has a complex about her small chest (even treating it as her bug).
Karma Akabane (赤羽 (カルマ), Akabane Karuma)
Voiced by: Nobuhiko Okamoto (Japanese); Austin Tindle (English)
Karma is one of the students in Class 3-E, but initially appeared as a genius Red Devil who lived in a northern cave. His bug is when he is looking down at someone, his luck drops drastically, which stays true to his name. One of his notable bad lucks is when washtubs from nowhere hitting his head countless times. He joins Class 3-E after Koro-sensei "defeats" him.
Yūma Isogai (磯貝 悠馬, Isogai Yūma)
Voiced by: Ryōta Ōsaka (Japanese); Jerry Jewell (English)
Isogai is one of the students in Class 3-E, and the class representative who is labeled as the class' "gentleman" (イケメン, ikemen). Out of the students, he has the most different armor that is most "hero-ish" but because his family is poor, he only could afford the front half of his armor, although this is revealed to be his bug.
Ryōma Terasaka (寺坂 竜馬, Terasaka Ryōma)
Voiced by: Subaru Kimura (Japanese); Marcus D. Stimac (English)
Terasaka is one of the students in Class 3-E, who has a big body and is the leader of 'rebel' clique in the class. In the anime, after a treasure box swaps his body, he is abandoned in the dungeon and trains until he eventually turns level 99 and becomes the strongest in the class. The fake version of him speaks English, and after the real Terasaka appeared, the fake one remains in Class 3-E.
Yuzuki Fuwa (不破 優月, Fuwa Yuzuki)
Voiced by: Kana Ueda (Japanese); Kristi Kang (English)

Kunudon (くぬどん)
Voiced by: Kurumi Mamiya
