Short summary
Karma continued toying with Korosensei, forcing Korosensei to find a way to deal with him. After Karma scares off two Class-D students from harassing Nagisa, he asked for him everything he knew about Korosensei, ecstatic to kill a teacher with his own hands. However, when Karma presents Korosensei an octopus stabbed with a knife, Korosensei sped off, obtained a missile and used it along with his tentacles to prepare octopus dumplings for him. After putting one into Karma's mouth, Korosensei tells Karma he will keep polishing him in response to his antics; he declares by the end of class, Karma's body and spirit would be completely clean.
