The Marui Inpu no Ya is a weapon created by Kaminoshi for his daughter Kamiko Otsutsuki. This arrow is controlled by the special frequency whistles she can produce that allow her to control it. The arrow's speed power and direction is based on the sound she emits to it allowing very versatile usage.
