Kai is busy practicing his Beyblade skills alone in the park when out of nowhere a gust of wind appears and starts slicing everything to pieces. It turns out that it's the work of Jack, one of Dr. K's Blader's, and he's got a Bit Beast that harnesses the wind. Once the Bladebreakers figure this out, Ray volunteers to fight, but Kai stops him and sneaks out in the middle of the night to battle Jack. Discovering Kai is gone, the gang runs and finds him just as he's about to begin the battle. The gang realizes Kai doesn't stand a chance against this wind Bit Beast because he can't see it. Reluctantly they let Kai fight. An intense battle ensues and Kai takes a severe beating as he waits to catch a glimpse of Jack's Bit Beast. Finally Kai summons Dranzer and spots the wind Bit Beast and defeats it. Defeated, Jack runs off while Kai leaves the rest of Bladebreakers in awe as he walks off into the night.
