A white flower with green leaves is tucked in her hair, as well as attached to her right sleeve. She has red eyes. Strung around her neck is a large golden key of unknown purpose. She wears a long white turtleneck dress with ruffles on the hem. The inside of her dress is yellow, and she wears a frilly green cape tied with a large bow of the same color over her dress. Her bottom half is that of an olive green serpent with the underside being light brown.

Background
Not much is currently known about Sin's past.

Minor

 * Seaside Dispatches 1 - Sin makes a brief appearance together with Reficul near the end of the manga, as well as during the Bonus Comic that also features their son Mors.

Reficul
Reficul is Sin's wife and lover. The two are extremely close with one another, and they have a child together named Mors. Sin refers to Reficul with "Reficul-sama." It has also been stated that Reficul is a "top" in their relationship.

Mors
Mors is Sin's son. The two are very close. Unlike with Reficul, he calls Sin "Mother" instead of using another name.

Lzet
Lzet and Sin are both lovers of Reficul. They are usually close, according to Deep-Sea Prisoner. Since Sin is said to understand that others can love multiple people, she does not mind Reficul and Lzet's relationship.
