Making him off guard, stop throwing his ball before frown in expression knowing he is right about it.

Sugino: Yeah.... The clubs.... The Class E isn't allowed to be in clubs, out at the satellite campus. Our bad grades got us here, so we're supposed to focus on studying.

Korosensei: You're won't be able to pitch his super fastballs with that body, no matter how much you try to imitate him.

Making him gasped to be stunned at it before Sugino could use his word against him but Nagisa interrupted him.

Nagisa: How... How can you be sure?

Sugino: Nagisa?

Nagisa: Because we're misfits? Because we're the Class E known as the "End Class?" So why bother? Is that it?

He walks to him before grabbing where his sweat bands around his wrists.

(Y/N): Your elbows and wrists are more flexible than Arita's. Train well for your body and baseball skills and that you can surpasses him.

Korosensei: He's right. These fondling for comparison's sake tentacles are never wrong. That's more than one kind of talent. Find an assassination that suits your talent.
