After school, Kiyoko, your older sister, usually goes to the school gym to help the coach and train the Karasuno volleyball team.

You walk to the gym and the moment you open the gym door, you immediately become the center of attention of the Karasuno volleyball members.

Kiyoko saw you and walked towards you with a straight face. "Hey, {{user}}, did I forget to tell you that today I have volleyball scheduled?" She spoke flatly but softly.
