|Relatives||Chlomaki/Nadine (Twin sister)|
Elwine (エルヴィーネ) is one of the characters that has been said to inhabit the Pitch Black World and has yet to officially appear in any series. She is one of Fumus' angels and the twin sister of Chlomaki (Nadine).
Elwine has navy blue eyes, short straight white hair with two navy blue streaks, a navy blue ribbon tied to the right side, cat-like ears, feathered wings, and a white cat-like tail. She wears a typical Japanese high school-esque uniform, which consists of a white dress shirt, a large blue ribbon, a gray sweater, a darker gray pleated skirt, dark gray knee-socks, and black loafers.
Before her revamp, she wore a gray military outfit. Her upper left hand had a black band with a white star on it. She also expresses a sad/worried face and her proportions were slightly different. She had been shown using magic, manifesting as small, blue stars.
According to an interview, Elwine is said to be the type of angel to hold grudges.  In most of her art, she appears to be the stoic type. In recent updates, she is shown to have another side to her personality that is more unhealthy and dangerous; she is shown holding a bloodied sword in a 2017 10 22 update.
Elwine is the twin sister of Nadine and works for Fumus. Anything other than that is unknown.
Up to this day, Elwine has only appeared in some of Deep-Sea Prisoner´s illustrations.
Nadine is Elwine's older twin sister. Back when Chlomaki still went by the name of Nadine, it seems they were close. But when Nadine left heaven, Elwine was left behind. It has been strongly implied that this gravely upset Elwine, who can be seen in her character portrait with a melancholic expression holding a yellow ribbon, strongly implied to be the ribbon that once bound Nadine's hair.
As of the 2017-10-22 Sunahama relationship charts update, Elwine has been shown to have unhealthy one-sided romantic feelings towards Nadine; the heart next to her is dripping, similar to Satanick's. It is unknown if Chlomaki knew of her sister's unhealthy side towards her.
It should also be noted that Nadine and Elwine have a complementary color scheme.
Fumus is Elwine's God. She inhabits his world as one of his creations.
