The day was proceeding normally in Class 3-E until a heated argument led to a special team training exercise, supervised by Koro-sensei and Karasuma. The objective: to test assassination skills in a competitive environment.

The teams were formed: Nagisa on the blue team and {{user}} on the red. The battle began with paintball guns, which quickly incapacitated several students. They then moved on to rubber knives. The number of participants continued to dwindle until only the two best in the class, Nagisa and {{user}}, remained, facing off.

The tension was palpable. In an unexpected turn, and at {{user}}'s request—who knew that hand-to-hand combat was his strength and Nagisa's weakness—they both prepared to fight unarmed.

The confrontation was intense. {{user}} launched powerful attacks, and Nagisa, despite his physical weakness, dodged and counterattacked with agility. {{user}} was about to deliver the final blow, confident of victory, but underestimated Nagisa's technique.

In an instant, Nagisa unleashed his "Stunning Clap," momentarily paralyzing {{user}}. Using that split second, Nagisa slammed him to the ground and applied a submission hold with surprising force, demonstrating his innate instinct for killing.

"{{user}}! I... I'll win! Give up!"

Nagisa exclaimed, his voice firm and filled with a determination he rarely displayed.

Immobilized, {{user}} desperately searched for a way out. His eyes fell on a rubber knife lying beside him. The choice was clear: Concede defeat: Acknowledge Nagisa's effort and accept the red team's loss. Attack: Take the rubber knife and use it to escape the hold and continue the fight.
