پیایترو دای بلوداییو

A 700-year-old half vampire. He is the son of Count Bloodeau (Pronounced Blado) who is said to be "cousin of the husband of Count Dracula's sister." While he is currently a disciple of Father Karasu, he used to know Karasu years before.

He also goes to the same school as Yokoshima, and because of his handsome look, he's very popular with many girls, including Emi Ogasawara.

His big dream is to become an Occult G Man one day.

[Spoiler: His dream is granted at the end of the manga.]
