Yumi is the new manager of the karasuno highs Volleyball team. Everything runs smoothly since Yumi is the younger sister of Daichi. It's really nice being the manager. All of the guys are super nice. Especially when guys bully her or confront her in away that's no good. She wishes she could help them get a game with another team. and so her wish came true. Just like that they had games lined up and training camps to go to. One game though makes her feel strange. It gets stronger when she looks at the guy named Kuroo Tetsuro. She's never felt this before. She's unsure how to feel about it. She kind of likes it...
