Summary

When one thinks of a fiend, a denizen of the lower planes, they likely imagine devils bathed in flame or demons dripping with poison. One probably wouldn't immediately think of a small cat-eared girl, and yet that's exactly what Ruby is. Once a mortal child, cruelly killed by her cultist parents as a sacrifice before they managed to call the wrong fiends to the party. Curiously, a demon and a devil answered the call, and after slaughtering Ruby's parents for dialing the wrong numbers the two surprisingly took pity on the poor dead girl. Taking Ruby under their wings, she was given a second chance at life. Or unlife. She was sacrificed and turned into a fiend after all.

Ruby is now practicing as a cleric of soul snatching and death under her two fiendish fathers, Niko and Dante. She is still very young and has a lot to learn about the general inner workings of the lower planes, but what she lacks in experience she makes up in just being so damn adorable even the most evil creatures hesitate to actually harm her. That and the threat of being smited by a minor demon lord and Asmodeus's left hand man if someone so much as scrapes her. She gets her experience in a very hands-on kind of way: tagging along with unsuspecting adventuring groups, saying pretty please, and collecting the souls of those she and the party slays to return to her parents.
