See No Bit Beast, Hear No Bit Beast (姿なき刺客, An Invisible Assassin) is the thirty-fifth episode of Beyblade: V-Force.
At night, 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 and damaging Dranzer. The same gust of wind attacks Tyson and Zeo at the BBA gym, cutting Zeo's Zeronix in half and even creating a hole in the ground. They spot a suspicious kid leaving the room, but they quickly lose him.
It turns out that it's the work of Jack, one of Dr. K's Bladers, and he's got a bit-beast that harnesses the wind. Jack eventually attacks Max, too. Ozuma witnesses the attack and informs his team mates about this new fighter.
Once the Bladebreakers figure that a bit-beast is behind the attack, Ray volunteers to fight, but Kai stops him.
At night, Kai secretly sneaks out 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, but reluctantly, they let him fight, while the Saint Shields secretly watch from among the woods. 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, a weasel with sickles in place of arms, and defeats it. Jack runs off while Kai leaves the rest of Bladebreakers in awe for the damage Dranzer has taken as he walks off into the night.
