Ryougi Shiki was born in the family of demon hunters. She's a girl who possesses the Mystic Eyes of Death Perception (similar to Toono Shiki's), a supernatural ability that allows her to see the "lines of death" on any living or non-living object.
Ryougi assists the "Garan no Dou" agency run by Aozaki Touko, helping to handle the paranormal cases when combat is required.
