Shiki (Mother)

Senri's mother is the former mistress of Rido Kuran. In her youth, she was a famous and respected actress. After her affair with Rido, she grew mentally unstable and unable to care for herself properly. She has a great vanity with a lovely hairbrush her son uses to brush her long hair.

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 greedy when she demands blood from him. Rido described her as easily controlled. Not much is known about her before she had her affair with Rido Kuran.

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.

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

Powers & Abilities
As an aristocrat, Lady Shiki possesses unnatural beauty, and lives longer than humans. She can consume blood and heal her injuries at an increased rate.

Senri
He is her son, and even when he describes her as greedy, he still cares for his mother despite not going home often to see her.

Rido Kuran
She is Rido's former mistress, though she seems to hate him as she told her son that he is starting to look like "that demonic bastard".

Uncle
She is his niece and they have been shown to have had a close relationship in the past.

Rima Toya
Not too much is known about her relationship with Rima, as they have never been shown interacting. However, Rima admired her growing up as she loved watching her films from her acting career. This is what made Rima pursue a career in modelling. Upon Rima’s marriage to Shiki, she is now Rima’s mother-in-law.
