Weissvogel is the first of the angels of Refess. Her original purpose was not to fight, but to guide people into the light of Refess.
She wields the power of purity, and it's said that if you lay your eyes upon her, the ugliness in your mind will be washed away. Her task is to use that ability to increase the number of Refess' adherents.
She also frequently appears as a divine Angel destroying demons, as Refess keeps her busy.
The sword and shield she holds are the holy sword and shield used by White King Eyguina.
