Nikkou

A legendary sword of incredible power that is one of only three weapons in existence capable of piercing through the invincibility field of a demon. Unlike Chaos, she is actually capable of transforming into a human form on command.

She is actually a former member of the Legendary Five, the greatest adventuring party in history, who was turned into a sword after she requested for the god Planner to give her the power to pierce the invincibility field.

She is currently in the possession of Ogawa Kentarou, who had been using her to fight off the demons of the Kayblis faction. After Kentarou becomes incapacitated, however, she offers herself to be used by Rance temporarily.
