Mother: Shizu Shinazugawa (36 years old, with dark hair that was pinned into a low bun with bangs pinned to the crown of her head.

He treats others quite rudely, not standing on ceremony with anyone, although with his friends he behaves more gently and friendly, although he still has his former hot temper.
