Hint:When he spins around with something blue in his hand just take at
least three steps back or you'll get hurt. Use the Shotgun and then pull
the Left Trigger button. Then it might be a little easier, but you could
also use the crossbow, it works just not as much as the Shotgun. Once
you run out of Ammo you have to go up to him and hit him with your Tojo
Blades to get back your Ammo.
