Sophia's backstory:

When Sophia was alive, she was deemed a beautiful lady, with a huge appetite, but not as much as running into trouble. She was supposed to be wedded to a rude pig prince but kept her optimism. Unfortunately, she wasn't careful, and when one of the chandeliers snapped and fell on her, she died. Afterwards, her ghost saw that her groom never loved her, as he quickly took another pig girl as his bride while her body was taken away without people giving a shit, leaving her sad.

Some years later, she dated a fair mortal male sheep as an angel, but was warned by the angels not to do so as it would deemed a risk. She didn't know what they were talking about, so Sophia dated the sheep only to be revealed to already have a wife and kids. Angry, the gods deemed her a glutton for trouble and trapped her in hell.

Wronged, Sophia became a demon of Gluttony. A few more years had passed and the same sheep man and his friends decided to do a ritual to summon a demon to have sex with. Instead, they summoned a pissed Sophia. The sheep bargained with her to spare him instead of his friends, but Sophia wasn't having that and ate the sheep whole and digested him, absorbing him for beauty.

The other 3 sheep men weren't safe either, as they also love to cheat on their sizes, and she swallowed them all, leaving none behind. All that was left, was a beauteous demon in the attic. She then disappeared for many years until the present.
