如月 兼定

Rei's father. Married to her mother at a young age, he's still in his forties. He lost his wife to the fire that also killed Kazuha's parents. He has since been living in a wheelchair as the result of the accident, covering scars with bandages. Due to his poor health condition, he cannot participate in the ritual which is usually the job of the head of Kisaragi family, therefore asking Seiichi to attend for him. He wasn't expecting Seiichi to become the next head of the family. But to avoid conflict between branch families, Seiichi as a childhood friend to Rei is the perfect choice for the ritual. He would have no opposition to Rei and Seiichi's marriage, if they too wish so. Having been cared since young, he doesn't treat Sae as a servant.
