I'll need to ask Kasper about some stuff but here's the list:

The List

RM: the main RM that has an actual name, but he won't tell us. The personification of Wrath

Swap: everyone hates her and yet she hasn't done anything. The personification of Lust

Shopkeep: not shopkeeper, just shopkeep, often shortened to just shop. The personification of Greed

Forest: the most normal one, hasn't represented his sin yet. The personification of Gluttony

Mask: he has a comedy/tragedy mask (i forgor which). The personification of Envy, i think.

Gameshow: not by kasper. They own a casino...you know shop should own one honestly

Stitch: not an RM, just a mimique. Yes, a pokemon
