Gluttony

A demon that eats everything it sees using the gigantic mouth located on its stomach. It is the altered spirit of desire form taken by greedy humans who used a certain secret technique. No matter how much it eats, their hunger is never satiated, so their pangs never ends. Oddly enough, they seem to enjoy that. Because they hold memories of when they were human, they can make intelligent decisions, which makes them quite difficult to face. It will use any means available so long as it can satisfy its never ending hunger.
