Kidō Gourd

The Kidō gourd (鬼道瓠, Demon Way gourd) is a specially crafted Kidō-based gourd with the ability to absorb other objects and beings into it. It acts as an "infinite storage" device and has the capability to suction in beings of both spiritual and physical levels. It has also proven to be able to hold attacks within it, that can be released later on at Hatake's discretion. The Gourd's main function is the containment of Hollows for further study, but Hatake has since made it his personal weapon.
