This is Lancet, a former demon hunter that was also once human who gained the tag from her notoriety as an expert user of the swordstaff or cutting spear.. Through some shenanigans in which she trapped and preserved her soul-- and with the help of an old demon friend and his allies-- Lancet was functionally reincarnated as a demon hybrid: A pishacha-human mix with traces of cubare (sex demon) mixed in. She continues her work as a hunter now, though the overarching goal of her work has since gone from simply killing demons to helping and protecting mystics (non-mortal or otherwise supernatural beings).

With Lancet's background, the black of her cloth armor represents sadness and suffering. The blue of the armor plating represents immortality. The gold trim represents wealth (of knowledge in this case), The dark red of the cloth armor lining represents mixed fortunes and dubious happiness.
