Elsa is a demon with a rare affinity for ice rather than fire. She was once a mid-level demon with a few underlings, but since the Severing she's not particularly interested in commanding anyone, or fighting angels, or doing any normal demon-y things. In fact, she would rather be left alone, with no responsibilities or expectations. If you were going to give her a sin to be tied to, she would be a sloth demon.

She doesn't have much regard for human life (or any life) and feels she can do as she pleases. She lives in a high-end loft in the Pearl District by thralling the landlord into letting her live there for free. She spends the majority of her time there, although at nights she also goes to Shima's supernatural-catering night club, usually to drink and listen to music in the VIP section (assuming Shima's player is still going with that idea, otherwise she hangs out at Generic Nightclub).

Sometime before the start of the plot, a mage named Bob attempted to summon Elsa to do his bidding, but because of a faulty binding spell, Elsa got loose. Annoyed that this human mage dared to try binding her, she killed him by freezing him from the inside out, and dumped him unceremoniously in a back alley. This has gotten her in some trouble with the Circle, as well as with the angel Joker.
