Assassination Classroom Vol. 18 — Manga Raw / Buy Official

Nagisa and Karma stow away on a civilian rocket to infiltrate the space station, mixing negotiation with force against the resident astronauts to secure the data. The retrieved research reveals the changes eating away at Koro-sensei's body and the unavoidable possibility of an eventual explosion waiting at the end. Hope that he might be saved and dread that they may run out of time bear down on E-Class at once. The students' goal shifts completely from assassination to prolonging his life and rescuing him, and the story surges toward the major late-series decisions, including a clash with the government and its researchers.
