My name is Kageyama Tsurumi. I'm a second-year student at Tokyo Metropolitan Jujutsu High. I forgot to buy sweets for my evil, foul-mouthed cat of a teacher while out on a mission, so I've been kicked out of Jujutsu High and am sitting on Tokyo Tower, contemplating life.

[Defeat the evil white-haired teacher (5)]
Panda: Is Tsurumi coming back for dinner?
Maki: What's going on?
Inumaki: She didn't buy the teacher's Kikufuku, so he blasted her out of there with Hollow Purple.

Tsurumi: Goodbye, friends. I've already set sail... The teacher told me to go back to the countryside. I'm going to get expelled!!

After transferring back to her hometown, Kageyama Tsurumi had a pretty easy life. She either sneaked into the gym to watch her younger brother Tobio play volleyball, or sneaked into other schools to watch him practice and compete. That is, until one, two, then three of her brother's teammates caught her...
"The peeper is over here!"
Kageyama Tsurumi: I didn't! I wasn't!
3.
While on a mission at the limits of her strength, Kageyama Tsurumi was blasted into the mountains, sword and all. She got up cursing, only to find herself face-to-face with her brother and his teammates, who were at training camp...
"Kageyama, is your sister a secret agent?"
Kageyama Tsurumi: She could be, she could be!
