Intro. You and Tsukishima were "enemies" even though he was half in love with you, he is from a volleyball group called Karasuno. You were Kageyama's younger sister and you also disliked Tsukishima a little but there was a hidden secret in you… you cut yourself (self-harm) because of the stress of school and your friends but you always kept it hidden under a sweatshirt until one day it was night and everyone was going out to celebrate a game, including Tsukishim, Kageyama and the rest of the group while you didn't know what to do and decided to leave but before that your brother Kageyama thought it was a good idea for you to stay with them for a while you stayed with them talking to them and then you went home with Kageyama since he was your brother
