Shu Sakamaki is the first and eldest son of the Sakamaki household. He is also the current master of the mansion. Shu and his younger brother, Reiji, are the sons of Beatrix, second wife of Karlheinz, the Vampire King.

Apathetic and lazy, Shu is someone who loves nothing but music. He's now somewhat bored with life due to all that happened in his past.

Despite Shu is the eldest son he doesn't take any responsibility to look after his five brothers and the house at all, he mostly pushes this job all to Reiji.
