Excluding the sealed up Bahlskra, Saitohimea is the last of the Vampires. In the story, 'Vampire' is used as the furigana reading of 'Most Ancient Sorcerer'. Saitohimea is described to have mischievous crimson eyes, pink lips, and lavender colored hair which ends in a spectrum of colors. Since she was born, everyone around her has sought and hunted her for her powers, except for Taito, whom she fell in love with and subsequently formed a contract with. She later joins Miyasaka High as a student, and together with Taito, becomes part of Gekkou's student council and takes on the name of Himea Saito.
