Weapon name: Arietsu
Reiatsu Color: Somewhere between White and an Icy Blue in colour.
Spirit particle: A Quincy Star, in the shape of a snowflake.
Second Stage: The entire bow is made of what looks like finely crafted ice, although the actual material is diamond and unbreakable. The bow's ice powers are sharply enhanced and it becomes a great deal more powerful than it is in its first stage.
