暗殺教室 4 [Ansatsu Kyoushitsu 4] by Yūsei Matsui

5.0

Acquainted with Bitch-Sensei's master, a competition forms between the both: whoever "kills" Karasuma in the next 24 hours wins. If Bitch-Sensei wins, she gets to stay, if she loses, she must leave. In the meantime, Koro and Karasuma have their own little secret bet in which if Karasuma survives the 24 hours, Koro will stay still for 1 second!
