Seiren

Seiren (星煉, Seiren?) A student of the Night Class, she is Kaname Kuran's unofficial bodyguard. She is usually the first to defend Kaname from anyone she regards as a threat. For example, she barely refrains from killing Zero when he points a gun at Kaname for comparing Zero to a level-E. It seems she also acts as a spy for Kaname.

Seiren is a highly trusted vampire, when Kaname and Yuki return to the Kuran mansion in secret, Seiren is already there having prepared their quarters.

She is a very quiet character as she only speaks when necessary.

She shows mild liking toward Kaname.
