Summary
Designated as seat number 27, Hayasaka, Ritsu is a killing machine imported from Norway with the specific mission to eliminate Koro-sensei. Initially, she operates with robotic precision, calculating every move and successfully landing a single hit on her target. However, after her classmates complain about her assassination style, which consists of a non-stop barrage of shots, Koro-sensei completely overhauls her. He installs a larger screen that covers her entire body, updates her facial expressions to be more lively, and alters the way she speaks.
