Ep. 22: Terasaka intervenes as Nagisa overcomes Takaoka using Lovro's technique and a stun-gun.

Terasaka stops Nagisa from succumbing to rage by throwing a stun-gun and urging him to reflect on what matters. After enduring a severe beating from Takaoka, Nagisa applies skills learned from Lovro to execute a secret move, shocking his opponent with a sudden clap. He then uses the stun-gun to force Takaoka to his knees, displaying the smile he dreads before rendering him unconscious. The three assassins previously mentioned clarify that the virus deployed was merely an enhanced food-poisoning agent that will eventually dissipate, as they opposed Takaoka's methods. The following day, once the affected students recover and Koro-sensei emerges from his crystallized state, the class utilizes the remaining vacation time before returning to school for the second term of their assassination classroom.
