Mei

She is the Peace of Mind Inn's idol.

She exhibits an energetic happy-go-lucky persona when interacting with guests but can give out a threatening persona to put unruly people in their place. As long as she's facing a paying customer, she doesn't care about race or origin, whether Human, Pantheran, Demon or even Fallen, it doesn't matter to her. She further doesn't care what customers do in their rooms so long as they don't bother their neighbours, or cause property damage.

When Diablo openly declares his intent to "torture" Rem, and Rem objects, rather than be concerned about the torture, she's more concerned over Rem being too loud.
