Once an all-powerful, merciless and heartless demoness, Jahy lost everything when her world was destroyed and became stuck in the form of a child. Deprived of her full powers and reduced to nothing, Jahy is now trying to revive the demon realm while trying to survive in the human world. Second-in-command to the Demon Lord (formerly), Waitress (currently). On the t-shirt she wears as a child, it says "Restore the Demon Realm" in Japanese. Her age is unknown but she must be very old.
