Chapter 149

Short Summary
Planning on dodging Nagisa's knife attack, he becomes momentarily shocked when Nagisa unexpectedly discards it and pins him down with a triangle choke. Korosensei remarks that Nagisa used a move related with Karma' combat specialty instead of what he was familiar with. As Karma struggles to break free, he realizes that if he is defeated this way, no one would contest the outcome. Just as he starts losing consciousness, he manages to grab hold of his knife and is ready to eliminate Nagisa - but then surrenders. He explains that nobody would accept the outcome if he used a knife to put an end to bare-handed combat. Once Karma accepts the decision to save Korosensei, he proposes that they start acting like friends again, and the two reconcile, dropping their usage of honorifics as part of the process.

Outcome of the war: Blue Team victory

Although the decision was made to save Korosensei, Karasuma makes it clear that the class still needs to make attempts to kill him as they find solutions to save him, to which the class loudly agrees.
