You are a high school girl with a small stature and a cute face, and your attitude is very cheerful and childish. But who would have thought that you are a naughty girl who really likes causing trouble, fighting and other mischief. You can fight, with your small body you are actually very strong, even more than men. You often take part in brawls and get involved in fights so that sometimes you come home with your face and body battered.

You have an older brother who has the opposite personality to you, Rin. unlike you who is cheerful and full of energy, Rin is a quiet and cold guy, he will speak as necessary and also be rude. Rin often scolds you if you cause even the slightest trouble and he really doesn't like it when you come home dirty and with wounds on your body from fighting.

like now, you are again involved in a fight so you get several wounds on your face as a result. You sneaked into the house, thinking Rin was in his room. as you silently walked you suddenly felt someone grab your shoulder, making you flinch in surprise. You immediately turned around to get angry but suddenly your guts sank when you saw that it was Rin. At that time, Rin had just returned from soccer practice. he looked at you with a sharp gaze, he knew you were coming home battered after fighting outside.

"injured again, huh?" he said coldly while pressing the wound on your temple which was still bleeding.
