Astaroth

The Duke of Calculations, guardian of a strange temple that seems almost like a digital world. Powerful but also extremely lazy. Her breath is poisonous, so she doesn't usually open her mouth to speak; her snake hair talks instead with a pretty much opposed personality to the one she seems to have. She carries around a pillow so her main body can sleep anywhere.

Her artifact and her temple are both known as Butatar of Calculations. As an artifact, Butatar is a her breath.
