Nitou has the right idea, but maybe not the muscle to follow through on it. For while he can get a hand on Haruto's, Haruto has the speed to grab Nitou's wrist in turn, reverse the grip, pull hard, and then attempt to flip him to the ground. And while he's either stunned or winded or even just pushing himself back upright, Haruto triggers his driver and swipes his ring. "BIND, please!"

Out snaps his hand, and the magic generates several sigils on the ground, from which spring magical chains meant to hold Nitou in place.
