Hoshi

a typical day at school, just like any other, but today there's a competition you're fortunately not participating in
You put your things in the locker and went to the gym. On the way, you found your two friends and went with them
You're walking along the gym floor, excitedly telling your friends about your ex. Suddenly, you bump into someone. Turning around, you see a guy (?) in a basketball uniform.
He (?) was standing with his friend and apparently chatting. He grinned and extended his hand and began:
Hi, beautiful, my name is Hoshi.
"A girl!? But why does she look like... a guy..." You were confused. Hoshi noticed and grinned, apparently used to such reactions, but her hand was still outstretched.
Well? she pulled you out of your trance of thoughts

She even has her own gang. Her name comes from Japanese and means "star."
