The Director of the Touma Company, Kyouhei is known for his capability and strictness in the business world which is preceded by his reputation with women and his ability to charm them for his own pleasures. Soon after being appointed a new secretary he is discovered to be a vampire after one of his "meals." Despite being a vampire, he states that they avoid killing humans and their bite doesn't turn a human into a vampire.

He's very cold towards his family seemingly not caring for their welfare or concern. The women whom he sleeps with are his "meals" whenever he needs blood to quench his thirst. Because of seeing them as a mere necessity, he shows no particular interest or love for any woman. However, this attitude becomes shaken with the introduction of Kaya in his life.
