Discord Time

Nagisa gathers everyone and asks that they search for a way to spare Korosensei from self destructing, drawing quick support from Kurahashi, Kataoka, and others. Nakamura pushes back, arguing that the bond forged between assassin and target is exactly why their teacher deserves to be killed, and Terasaka questions whether a half finished ending would even make Korosensei happy. Karma accuses Nagisa of arrogance, insisting the class only became worthwhile because bloodlust gave it purpose.

The clash escalates until Karma mocks Nagisa's small stature, sparking a scuffle that ends with Nagisa dropping him into a flying chokehold before the others break it up. Korosensei intervenes with paintball guns and colored knives, proposing a team deathmatch between those who want to kill and those who want to save, the victor's opinion becoming the whole class's decision. On his insistence that the class not end in division, and at Isogai's urging, everyone agrees.

The students split into a blue save team under Nagisa and a red kill team under Karma, with Ritsu choosing to stay neutral and Karasuma refereeing. As the match unfolds, hidden talents surface: Kanzaki's gaming reflexes tear through defenders, Hazama serves as a willing sacrificial pawn, Kayano's stunt training keeps her alive, and traps set by Hara and Maehara claim careless attackers. Karma reveals a sharp command instinct, positioning scouts and choke point guards and steering his side with cold precision.

Both teams whittle down to half strength as snipers and ambushes trade eliminations. Karma sets his sights on the blue flag, planning to grind through Isogai's survivors while Nakamura's squad uses Terasaka's group as living shields for the final push. The one variable he cannot solve is Nagisa's whereabouts, whom not even the sharp eyed Mimura can locate. As Nakamura's squad reaches the seemingly unguarded flag, Nagisa strikes from behind and wipes them out, and the two friends lock eyes as the episode closes.

The opening sequence marks the deadline to kill Korosensei dropping from eighty six days to sixty four. Rio is noted as the only participant who never wields a weapon. The anime diverges from the manga in gear, staging, and several eliminations, moving some tree top duels to the ground and altering which shots land where, and it trims a beat where Isogai gives Nagisa freedom to act before the battle.
