Seiren

Seiren (星煉, Seiren) is a student of the Night Class. She is Kaname Kuran's bodyguard.

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

Appearance
Seiren is average in height and has a pale complexion, shared by many of the Night Class vampires. She possesses silver to pale violet hair that matches her pale violet eyes which appear relaxed. Her bangs stop just above her eyebrows and are short in length.

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. She is a very quiet character as she only speaks when necessary. Seiren may come across harsh at first, and she can get irritated very quickly. Some say she can be a little too serious. Once Seiren befriends a person she will defend you to her last breath. A word to the wise... don't threaten her or others she knows, or she will kill you without hesitation.

Background
Seiren is usually the first to defend Kaname from anyone she regards as a threat. For example, she barely refrains from killing Zero Kiryu when he points the Bloody Rose at Kaname. Seiren also appears to serve Kaname in the capacity of a spy or informant. She is often seen in the background ever watching for danger or hidden to retreve information which makes her mostly a loner. Seiren is a highly trusted vampire with the Kuran family. After Rido Kuran was killed, Seiren continues following her master, Kaname. Seiren is a highly trusted vampire, as when Kaname and Yuki return to the Kuran mansion in secret, Seiren is already there having prepared their quarters.

Powers
Seiren's main choice of weapon is her body. Being highly skilled at various martial arts as well as ninja-like weapons, Seiren is able to quickly subdue multiple opponents. Also, as a vampire she possesses the ability to erase minds and put people to sleep when ordered (though this is a common ability for all vampires). She also has the ability to heal very quickly. (though most vampires have this ability)
