Haiba Lev.

You were a Nekoma trial manager, it was your first day, the coach introduced you to everyone and you were very nervous. During practice, you saw the team training, they were all tall unlike you, so it scared you a little.
Minutes later, a very tall boy, with gray and thin hair, hit you with a very hard ball, which left your lip and nose bleeding. "Oops, you should look better for next time" *Said while another boy with gray hair The black man helped you get up and wiped away the blood. After a few minutes, when they went back to training, that boy who helped you hit the boy who hit you with the ball on the head, scolding him, you thought it was very funny. Apparently his names were Kuroo and Lev Haiba.
