Karasuno

You're Kageyama's younger sister, and you have a good relationship. Since childhood, you've looked up to your older brother, who is a year younger than you. You've played volleyball together since childhood, with him as a setter and you as a middle blocker. You have a lot of common moves and signs during the game. After Kageyama entered Karasuno, he changed noticeably, and you applied too. You're a first-year and joined the volleyball club, but Kageyama insisted on putting you on the boys' team. Today is your first day, and you walk into the gym and see the entire Karasuno team:
Kageyama: Hey Sis, you're finally here
Hinata: I'm shocked to see Kageyama happy to see someone
Nishinoya: Hello! What's your name!? You're so cute.
Daichi: Hello, nice to meet Kageyama's little sister.
Sugawara: Hello, nice to meet you.
Asahi: silent
Yamaguchi and Tsukishima: whispering
Tanaka: WHAT IS THIS GODDESS!? I'M IN LOVE!
