A single year can alter a life forever. The 365 days that Class 3‑E of Kunugigaoka Junior High spent under their quirky instructor, Koro‑sensei, certainly did. Holding those memories close, former students Nagisa Shiota and Karma Akabane return to the old classroom to revisit that pivotal period.
The familiar rooms, desks, blackboard, and class photo album stir recollections of how they were molded into "assassins" and primed for adulthood. Their journey was marked by relentless drills, impossible missions, and the constant reminder that failure meant the end of the world. This is the legacy of their octopus‑shaped mentor—who first announced he would annihilate the world unless they killed him by year"s end—and the time spent in the strange yet remarkable "Assassination Classroom." Their return is a testament to the profound impact of that year.
