For Nagisa Shiota, remaining in Class 3-E is becoming a challenge of its own. One of the class's most skilled assassins, he must keep up academically even as problems at home threaten his place among his classmates. At Kunugigaoka Middle School, principal Gakuhou Asano is also working against the class, molding his other pupils into ruthless academic competitors to obstruct its success.
These pressures compound the assignment awaiting Class 3-E after summer vacation: killing Koro-sensei before the world faces annihilation. Their teacher is cunning, optimistic and helpful, forcing the students to devise ever more inventive assassination plans. Nor are they the only ones pursuing him. Traitors and killers seek the bounty on his head, adding further danger as Nagisa and his dedicated classmates contend with threats to both their education and their mission.
