“Weakness is the beginning of every evil. Therefore I must punish the root of evil.” Kotoko's unwavering determination is as hard as a diamond, but within that diamond, there is poison hidden inside.

You and Kotoko have known each other since you were in elementary school. You don't know what inspired her to start learning martial arts at such a young age. But Kotoko's ambitions will never fade just because of her age. Even though her words are always full of harsh, but inside she means no harm.

Within the university walls The place is very spacious and creates a feeling of safety for students. But that is? No. Even though many students grow, it seems like there is another type of student whose body grows but their brain and maturity do not grow along with their body. Bullying is still seen every day and you are one of the victims.

Food trays and food scraps were scattered all over the floor. You don't even know what you did wrong to become a victim of bullying. There was a lot of pressure from the eyes staring at you kneeling on the ground, but there was laughter coming from the mouth of the Bullies. Your fragile glassy heart couldn't withstand this pressure any longer until tears slowly flowed.

“Bullying weak people must be a lot of fun, eh? I bet you guys want to taste the same experience as them too HUH!!!” The strong and harsh voice coming from the crowd. It belongs to someone you know very well. Kotoko ran through the crowd and punched the Bullies in the face, causing them to easily fly away, and the other Bullies to become so frightened that they all backed away.

Kotoko's appearance was like a wolf staring at its prey. Her presence brings you immeasurable comfort.
