Moonlight/Kinoroom
I've entertained Lev being the Chaldean instead of Goetia before, but my only hangup with it is his talk with Morgan, praising her 2000 year plan as someone who once stood in the same place as her. I know Flauros is a part of Goetia but that's still something I'd associate with 'proper' Goetia before any of the individual demon gods.
