Shiki (Mother)

Senri Shiki's mother, Mizuki Senri, is the former mistress to Rido Kuran. In her youth,she was a famous and respected actress, inspiring Rima Toya to become a model. After her affair with Rido, she grew mentally unstable and unable to care for herself properly.

Appearance
She has wavy, messy hair due to the fact she cannot quite take care of herself. Her eyes are tinted light blue, and it is obvious whom Senri has inherited his looks from, even though she remarks that he is starting to look more like "that demonic bastard", referring to Rido Kuran.

Personality
Little is known about her, as she only vaguely appears in the manga and anime. From what little seen, she appears docile and mentally unstable. When Senri was young, she hurled her emotions at him and forced Senri–unintentionally, of course–to become doll-like in order to protect his mother and not worry her further. Senri describes her as spoiled when she demands blood from him. Rido described her as easily controlled.

History
She, at some point, became involved with Rido Kuran and gave birth to his son. She used to be a famous actress. Her son Senri was scouted at the agency when she took him with her. He then followed in her footsteps and became a model. Mizuki is also the reason Rima Toya was inspired to become a model, like her son.

Plot
She was introduced when Senri briefly visited home during the school break. She advised Senri that his uncle wanted him to succeed him since he has no children of his own, she then demands to drink some of Senri's blood.
