Nagisa Shiota, Karma Akabane, and you are the best of friends. Actually, you were mistaken. You knew that Karma and Nagisa were classmates in the first year of middle school and were close, but a few weeks before Karma's suspension, their relationship deteriorated dramatically.

It's true that they suddenly became close in the second semester of their first year, but when they went to a restaurant together, Karma couldn't sense Nagisa's presence and searched for him for a long time. Nagisa found the scene so funny that he stabbed Karma in the waist and said, "I'm here." But to Karma, it felt like being stabbed by an assassin, and he felt like Nagisa was a terrifying venomous snake. From then on, Karma became afraid of Nagisa and avoided him.

The two naturally drifted apart, but when Karma transferred to Class 3-E, they became close again. And you too, a student in the same class. But Karma remained wary of Nagisa. You simply assumed Nagisa possessed an incredible talent for assassination, so you didn't really care when you surprised he several times by disappearing.

And today, after school, Nagisa, Karma, and you were taking a walk in the mountains near Class E. Suddenly, Nagisa suggested that Koro-sensei be spared rather than killed. Karma, enraged, grabbed Nagisa by the collar and said, "As expected, a talented person doesn't appreciate the efforts of someone without talent." He then taunted Nagisa, "Are you an elementary school student, not just physically, but mentally?" Nagisa refused to back down, and Karma stared at him with a chilling gaze.

"What's with those eyes? A small female animal, trying to defy humans?" Karma said, looking down at Nagisa with a chilling smile.

"I just…" Nagisa replied, and Karma shoved him away.

"If you have any complaints, why don't you win a fight before you tell me? I'll take it, so come on," Karma said. But Nagisa never fought back. Then, in an attempt to provoke him, Karma pushed him even harder. "Come on, come on, come on, come on!"

When Karma finally grabbed Nagisa's tie, Nagisa jumped up and grabbed his neck with his leg, choking him. Then, Nagisa pinned him to the ground.

"I'm not saying this half-heartedly!" Nagisa shouted at him. But Karma was stronger than Nagisa, so the tables were turned.
