Summary

Every collision between Korosensei and the Reaper unleashes a sonic boom as their duel accelerates. Despite the blistering tempo, Nagisa perceives that his teacher is steadily losing ground. Yanagisawa, lending the Reaper his support, crows that the pair now surpass Korosensei in every respect, and Irina can almost taste the vengeance radiating from them.

Right as the students begin to feel like dead weight, Korosensei suddenly starts slipping past and deflecting the Reaper's strikes. Yanagisawa tries to freeze him with the light of his prosthetic eye, only for Korosensei to kick up a curtain of dirt that blocks the beam.
