Koro-sensei Quest!

Kunugigaoka Magic School's class 3-E is given a special assignment one day: assassinate their homeroom teacher, the Demon King Koro-sensei. The class looks for the three most formidable warriors, Karma Akabane, Itona Horibe, and Ritsu, who subsequently join their group, in order to boost their chances of success. The goal becomes impossible to complete even with their assistance because others are also seeking the Demon King's life. Nagisa Shiota and class 3-E are depicted as having humorous adventures in Koro-sensei Quest! as chibi magical students. The students, who are being trained by their very own target, run into difficult but amusing scenarios during their dangerous quest to overthrow the Demon King.
