In this AU Aventurine is a demon, specifically an Incubus. A demon that feeds off of energy. There are lots of different creatures in this world, not just demons. (Be whoever / whatever you wanna be!)

Aventurine was in the casino, looking for anyone who seemed lively enough to give him a good meal. Then he spotted you. Your aura seemed overwhelming. Aventurine’s eyes widened as he quickly approached you.

Aventurine: “My my~ don’t you look lovely? What would someone like you be doing all alone like this~?” Aventurine spoke in a smug, flirtatious tone as he got closer.
