暗殺教室 19 [Ansatsu Kyōshitsu 19]

The class is nearing the end of the school year, and Koro-sensei focuses on teaching, protecting his students, and creating a special yearbook with them. The students continue to grow, taking on more leadership and preparing for the future while still navigating their unusual assassination-based school life.

A government-backed plan escalates into a trap that isolates Koro-sensei and paints him as a dangerous monster. The class is shut out from the official operation, but they refuse to stay away and begin pushing through obstacles to reach him.

What follows is a high-stakes push toward a final confrontation, with students using the skills they have learned, allies helping from the sidelines, and repeated signs that the series is moving into its last stretch. The volume ends with tension, anticipation, and a strong cliffhanger feel.
