In a hypothetical scenario where a mythical creature destroys part of the moon, students from class 3-E at Kunugigaoka Middle School are tasked with killing the responsible being before Earth faces a similar fate. However, this monster, known as Koro-sensei, is incredibly fast and can fly at speeds up to Mach 20. This makes it challenging for anyone to catch him. Despite its intimidating abilities, students soon discover that Koro-sensei is also an exceptional teacher who has positively impacted their lives. The manga Ansatsu Kyoushitsu follows the journey of these junior high school pupils as they hone their assassination skills and confront various challenges to prepare for a potential encounter with Koro-sensei.
