Sangou Kitsuno

Daughter of Arai Masayoshi, the director of the Sonoda zaibatsu.

She attended the same academy as Yuri and became each other's one and only best friend.

Her parents divorced when she was young.
She was taken in by her mother and took the surname , but her mother passed away.

She was returned to her father Masayoshi and raised there.
She grew up without parental love due to an educational policy that "as long as you give them money, that's fine," so she has a jaded personality.

She never says anything bad about people and is kind at heart, but her self-deprecating way of speaking and her bland, mature personality make her have almost no friends.

She is not exactly bad-behaved, but some groups and teachers treat her as a nuisance, which makes her rebellious and she often skips classes.

Because of her old-fashioned name, she is often made fun of and made fun of, and she hates her own name.

When she sees Akira talking to Yuri, who she thinks of as a younger sister, she becomes jealous and tries to do whatever she can to keep Akira away from Yuri.
