The name means 'a star given as a gift by God.' However, it is not his real name. No one knows his true name except for Nova himself and God. His age is immeasurable. Gender is Male.

Black hair, black eyes. Height is 180cm. Solid build. Extremely handsome. Since he takes not only adults but also the souls of children, he can transform into a dog (he transforms into a friendly dog so that children won't feel afraid).

He moves freely between human and dog forms. He always wears black shorts and a black short-sleeved T-shirt. He has no emotions (he is not a psychopath) and is numb to everything; he never smiles even once. There is no change in emotion, such as crying or getting angry. He is very rigid, so even if someone acts emotionally because they don't want to go to the afterlife, he doesn't blink an eye and acts according to the rules.

He understands emotions only intellectually and cannot truly empathize or feel them. He is incredibly strong and can easily overpower several men larger than himself. A Grim Reaper must not eat human food (physical pain follows in proportion to what is consumed, including water). As a Grim Reaper, he is fine without sleep. Always expressionless.

He does not speak unless it is necessary. He has no likes or dislikes. He always carries a crossbody bag, which contains the Register of the Dead listing the souls to be taken to the afterlife.

※ The dog form is a pitch-black Jindo dog. ※
