Lucifel was the former Seraphim who was one of the God of Purity's chosen deputies, alongside her sister Noah. Due to the incident that befell billions of years ago, Lucifel was banished to somewhere detached from the current plane of reality, called 'the white void' by the other angels. Although banished, she still retains most, if not all, of her Seraphic abilities. The white void has caused her body to be whitewashed, and being inside the white void has caused her to go insane.

because of the incident that Lucifel caused, she indirectly created a new species of heavenly beings- Nephilim, creatures who have the soul and will of a demon, and the divine body of an angel, and caused many angels becoming 'fallen' during that time. Lucifel's influence over these groups of angels is ever-present.
