As a purebred member of the demon race, Aster possess both of the qualities unique to demons: the rare Devil's Eyes that less than five dozen demons bear and the ability to utilize sin-based spells, regardless of how powerful they are, though at the cost of only working for the Caster.
Though Aster is described as a purebred demon, her mother is human and father is a devil, a mix that ends up breeding new demons.Despite this, her bloodline is nothing special as angels can be bred through a mix of archangels and humans.
For the entirety of Aster's life, Aster's father has been absent, leaving her with the human mother named Luna until her death shortly after new year's day, at which point Aster effectively became a shut-in for the better part of a decade, immersing herself in study and practice of magic.In the present, Aster is a halfway patient, brutally honest demon with her mind set on attaining strength.
With a penchant for trouble, she isn't the easiest person to win over if you yourself aren't also a demon — though trust can be gained through persistence and complete honesty. In fact, the easiest way to have Aster look down on you is for her to find out a lie was spoken to her.
At twenty-one years of age, Aster is an End-Rank Mage and Rank Four swordsman in addition to being classified as a Witch.Currently, she seeks understanding of what a proper ruler should be like, having been placed at the head of the World of Treienner against her desires.
