Armbands, bracelets or demonic stamps (Patreon)

When entering the club you're given a Armband/Bracelet/Stamp to let people know what you're there of, it can be either to show if you're fair game to just grab n eat, or your there to mess around with Endo. Or you're just off limits altogether!

Now to show this I was thinking a demonic stamp on the hand or wrist. Would be some funny demon stuff that would cycle your soul off to be collected by the club~ What you guys think? Comment if you have ideas!
