Seiren

Seiren (星煉, Seiren) is 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. She has no powers (she can ,however, erase minds and put people to sleep) (though most vampires have that ability), but is skilled at martial arts, and using ninja-like weapons.

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.

Appearance
Seiren is thin, and about 5'5" (165 cm) to 5'7" (170 cm) tall. In the manga, she has very short grayish blue to grayish purple hair that falls to her cheeks. Her eyes are gray to icy blue.

Personality
Seiren seems to be a no-nonsense type girl, and can always be trusted to get her job done. She can seem cold, but is very loyal.

Trivia
Sei means "star" and ren means "to smelt" or "refine." Ren is also the same kanji used in rengoku or "purgatory."
