Just speaking about the anime and not including the manga, during the fight with Grayroad she reveals to be a "daughter of Belialuin" which could possibly be a side story in a next season.

Spoiler



Her sin actually is the gluttony she showed towards the Supreme Deity and the Demon King which ultimately led to the destruction of Belialuin and all its people.
