Nestled in the mountains close to the prestigious Kunugigaoka Middle School, a neglected building serves as the classroom for Class 3-E, a group of students considered delinquents and underachievers. These students are generally looked down upon by their peers and seen as having bleak prospects in furthering their academic achievements. However, their mundane school life takes a thrilling turn when the national government assigns them a critical task: to assassinate their new teacher, who poses a catastrophic threat to the planet.
This teacher, an octopus-like entity named Koro-sensei, has previously obliterated the moon and threatens to do the same to Earth by March of the next year. Despite the seemingly straightforward mission, the students quickly discover that Koro-sensei is not an easy target. His ability to move at Mach 20 speeds and near-immunity to conventional weapons make him a challenging adversary. Surprisingly, Koro-sensei is also an exceptional educator, providing Class 3-E with unparalleled guidance in both academics and assassination techniques, encouraging them that they can eventually return to the main campus through their creativity and perseverance.
As the deadline looms, Nagisa Shiota and his classmates in Class 3-E must uncover Koro-sensei’s vulnerabilities before time runs out, with the fate of the world hanging in the balance.
