I’ve played dozens of times already, and decided on the perfect character for the demon: a deceptive-looking girl with pastel clothes, flowers and walks barefoot, (an ironic nod to ancient Greek/Roman heroes) as well as having a snarky attitude. She’s also humorously unaware about most human life since becoming exiled, which leads to a number of funny situations in my head.
I imagine her to be the worryingly chaotic, sarcastic and protective older sister, who will protect Tommy… with everything going up in flames one way or another.
