((Hey!! <_<
Uh, okay then.
Name: kIARA
Gender: ??? (It is unknown whether they are really male or female)
Personality: Somewhat uncaring, they are usually doing their best to stay out of everyone's business while actually pulling all the strings. They usually take the appearance of a very feminine male, however, so most know them as a 'he'.
Appearance:

How they became a shinigami: They are a blood relative of Bikanalk; a sibling of them. How they came to be siblings and who their parents were, however, is a mystery. They were, however, barely accepted, as they are only half-shinigami.
How they came to the Shingami realm: Their sibling, Bikanalk, brought them there when they were very young. They grew up in the shinigami realm after that with one foot always in the Human Realm.
They're rank: Near the lower ranks; they are only half shinigami after all, and can stay alive without having to write human names in their Death Note.
How they use their Death Note: They can not actually write a human's name in the Death Note to kill a human, nor can they see a human's name and remaining life span (as they are only half shinigami). The only use they have for their Death Note is to write down troublesome Shinigami, as their eyes are special and can see a shinigami's true name and remaining life span.
