Kurohana

Kurohana is the goddess that governs over the Greater Law of Reincarnation, thus being nicknamed as the Greater Goddess of Reincarnation by other Divinity-level beings. She is well-known amongst the Greater Gods as one of the greatest divine craftsmen that exist in the Celestial Plane, with many gods flocking towards her just to get even a lousy piece of equipment made by her.

Deciding that she needed to craft a masterwork weapon that would allow her to transcend her current existence level and fight against those of the next level evenly, she decided to find a soul that would become the core of the weapon, which was Aurus. Then, due to the looming threat of the demons, the goal Kurohana had in mind for the masterwork weapon was not to surmount the gap between powers anymore, but allow herself to wield a weapon that would slay demons in a single slash.

Appearance
Due to her great prowess over the Greater Law of Reincarnation, she also has a decent amount of control over the Law of Deception, which allows her to change her appearance at will, even hiding her true form in front of Aurus when she first met him in his soul form.

Normally, her changed appearance resembles her true form closely, with only a few modifications done to make sure one would not recognize her that easily. Of course, to those that are quite close to her, her aura alone would be enough to distinguish her from the rest.
