Koro Sensei Quest! - S01

Class 3-E at Kunugigaoka Magic School is given an unusual assignment: assassinate their own homeroom teacher, the Demon King Koro-sensei. To boost their odds, the class recruits three of the strongest fighters-Karma Akabane, Itona Horibe, and Ritsu-who eventually join their cause. But even with their help, the mission proves nearly impossible, especially since they aren’t the only ones trying to take down the Demon King. "Koro-sensei Quest!" follows the comical misadventures of Nagisa Shiota and the rest of class 3-E as pint-sized magic students. Despite training under the very teacher they’re supposed to kill, the group faces one ridiculous challenge after another on their dangerous quest to defeat the Demon King.
