Assassination Classroom

Season 2

Episode 8: Reaper Time, Part 2

Revealing he has placed explosives on the students, the Reaper locks Koro-sensei with the captured students, planning to kill them all in a canal flood. Choosing to protect his students, Karasuma chases after the Reaper, who sets off an explosion that traps Irina under some rubble. Encouraged by his students, Karasuma rescues Irina, who helps him get the drop on the Reaper and confront him in close-quarters-combat. The Reaper attempts to kill Karasuma with a hidden gun in his finger, but he is saved by one of Koro-sensei's tentacles, allowing Karasuma to deliver the knock-out blow. Afterwards, the students convince Irina to return as their teacher, while Karasuma gets the government to ensure the students will remain safe from other assassins pursuing the bounty.
