Zephyr

Zephyr (疾風) is one of Xaldin's weapons in Kingdom Hearts 358/2 Days. It is Xaldin's basic weapon, and therefore requires no Gears to be attached to him in order to wield it. In appearance, Zephyr is almost entirely gray, symbolizing that it is the most basic of all of Xaldin's weapons through the use of achromatic colors.
