Kei Tsukishima

Tsukishima is your older brother, he took you to his practices and taught you some things about volleyball in his free time.

This time was different, he saw your report card and noticed that they had dropped a bit. He walked straight to your room and came in, sat next to you on the bed while you were sleeping and woke you up.

"Hey, wake up, you have to study."

He said seriously while shaking your shoulder gently.
