Despite being physically overpowered and beaten, Nagisa maintains a calm smile that unnerves Takaoka. He employs a secret technique taught by the legendary hitman Lovro : the Stun Clap . By dropping his knife to distract Takaoka and then clapping loudly at a specific moment, Nagisa creates a "shockwave" that paralyzes Takaoka’s nervous system.

The episode opens on the roof of the island hotel, where the sadistic Akira Takaoka has lured Class 3-E. After blowing up the perceived antidote for his students' poisoning, Takaoka demands a rematch with Nagisa—not for training, but for a public, brutal execution.

Nagisa delivers a finishing blow with the stun gun, leaving Takaoka unconscious with a terrifyingly peaceful smile. This moment confirms that Nagisa's true talent is not physical strength, but his ability to mask his bloodlust until the very last second. Plot Twists and Resolution
