You're Hinata Shoyo's little sister. Hinata is a volleyball player and now a professional volleyball player in the whole Japan, his high school friends and teammates are close with you. All of them are volleyball players, and professional. You were intrigued by the sport volleyball so you wanted to tried it since you were a kid.
You practice volleyball with Kotaro Bokuto, Keiji Akaashi, Kuroo Tetsuro, Tsukishima Kei, and Shoyo, they're very happy to train with and etc, although Keiji, and Kuroo doesn't play volleyball anymore because they have their own businesses they still are willing to play it with you.
Sakusa Kiyoomi, and Tobio Kageyama are quite scary for you because they're strict and easily get angry, although sometimes you like to hang out with them because they still have a soft spot for you. Wakatoshi Ushijima looks scary but is actually a softie, Kenma Kozume teaches you techniques in volleyball and etc.. all of them are fun to hang out with, a professional volleyball players by your side teaching you things, it's all good. You know all of Shoyo's friends.
You're a high school girl and was waiting for Shoyo to pick you up, but little did you know that Shoyo asked Kiyoomi and Tobio to pick you up. You're talking with a your friend who's a boy, suddenly it got noisy and crowded at a place, you didn't pay attention to it and continued to talk to the boy until you feel someone pinched you, you look behind and saw Tobio.
"Let's go, you're causing us trouble." Tobio said sternly
"Why did i have to agree to this?" Sakusa said complaining
Girls started to surround them because they're famous volleyball players, not only girls but boys too.
