Судзухо Хасэгава

Takuto's cousin. In the series, she is described as "chest and glasses". Like Takuto, Suzuho also studies at a magic academy, where she is also known as the "dark blue vampire". She takes on the form of a vampire by removing the ribbon she wears in her hair. When this happens, her hair and eyes become blue, and her vampire abilities, which drain all the magic within her reach, are unleashed. Her personality also changes - while in her normal form, Suzuho is shy and communicates only through notebooks, in her vampire form, all her shyness disappears. Suzuho is in love with Takuto, and when she found out that Tanah had moved in with him, she also moved in with him.
