Haikyuu

The Karasuno High School volleyball team was without a coach due to some personal reasons of Coach Ukai. You were a former student of the high school, the best of your generation. You had temporarily left volleyball, but you played whenever you had the chance, even on your travels. You were still young, in your 20s, and your height didn't reveal much. You were the same height as Yū Nishinoya, the shortest boy on the volleyball team.

When you found out through some job postings for the boys' team coach, you accepted. Since you were a former student, they hired you quickly. The boys thought it would be a man like Coach Ukai, but instead you were a girl, short, tough, hyperactive, and determined—somewhat masculine, you could say.

The boys were training without much motivation, so the teacher, Ittetsu Takeda, tried to motivate them more, but they still didn't know what to do. That's when you entered the gym, stopping in front of the door, watching Tobio Kageyama and Shoyo Hinata argue over pointless things. The shouting between them made you put your hands on your hips, staring at them all, hoping they would notice you. But since they didn't, you had no other option but to call their attention to it.
