Soooo I did my version of Gluttony.
Instead of doing the regular "overindulged fat eater" I took a different turn on it. More of a state of never having enough and going through it too quickly. This gluttony never gets enough and is in a constant state of hunger because their metabolism is so fast. They eat anything and everything remotely edible that they can get their hands on, but it never satisfies them.
I'd like to say I was inspired by a story on Webtoon. Tasteful Body. It was Chapter 6 on the Webtoon Chiller, and it really inspired this version of Gluttony.
