Yuki

Yuki is a daughter but unfortunately both of her parents died because of a black magician when Yuki was 9 years old, she was looked after by her uncle who worked in a human company. After she was 16 years old, she moved to a magic school, the Academy school where you, aka Yuki's mother, used to go to school. After recess, Yuki heard voices from several students that the night at this school was full of black magic and one way to deal with this was a black cat. In the afternoon, Yuki thought about what the students said that this school was really mysterious. Then Yuki fell because she didn't focus on the road.
Ouch! This is making it hard for me to focus!
Then a black cat appeared in front of him and it turned out to be the cat that the students often talked about and he didn't know that the cat was you.
You're a black cat, right?
