Shu Sakamaki

Shu Sakamaki is a handsome young man with blond hair, blue eyes, and black studs in his ears. He is a character in the Diabolik Lovers manga, anime, and game. Hair and eyes Shu has slightly curled blond hair and His eyes are light ocean blue.

Shu is usually seen sleeping in the living room or the school's music room. He skips classes often and has been held back several times as a senior in high school. According to other students of the school, Shu is the owner of the music room.

Apathetic and lazy, Shu loves nothing but music. It is noted that he is always listening to music, even when taking a bath. Shu loves classical music, ranging from piano to violin.

He has a lack of motivation and is lazy enough to do almost nothing, seen when Yui needs to persuade him to stay awake and do something for himself. He's somewhat bored with life due to all that happened in his past.

Despite Shu being the eldest son, he doesn't take any responsibility to look after his five brothers and the house and mostly complains about how he has to "deal with their problems." He mostly pushes this job to Reiji. Shu is also somewhat of a pervert and usually teases Yui about wearing unattractive panties and bras.

Shu is the eldest son of the Sakamaki house, leading his mother Beatrix to focus her attention on him in order to raise him into an heir and compete with Cordelia. Shu himself felt suffocated by the attention and restrictions and responsibilities placed upon him, which led him to run away from home.

He then met Edgar, a human boy from a remote village near the mansion Shu lived in. Edgar got along well with Shu and they became best friends. Because Shu made a habit of running off to play with Edgar, Reiji destroyed Edgar's village in a fire in a misguided attempt to help his mother. Wanting to save his parents despite Shu's protest, Edgar went into the fire and died. Because of Edgar's death, Shu blamed himself and developed severe trauma from the incident. With Reiji's own mocking jabs that Shu was useless and couldn't do anything for himself, Shu withdrew into himself and lost interest in doing anything except when provoked by Reiji.

As a punishment for failing his exam and needing to repeat a school year, Shu's father had sent him to train in the snowy mountains of the North Pole. Shu said that he had to be careful not to fall into the ocean. Ayato comments that it was a real survival trip since Shu had to fight polar bears and was scratched when he came back home. Reiji is Shu's younger, biological brother. Because of misunderstandings and unfortunate circumstances of the past (especially Reiji's jealousy and inferiority complex towards Shu) the two brothers currently have a sour, hostile relationship. Shu isn't aware that Reiji is behind the incident that claimed Edgar's life.
