Okay, okay, this was the kind of situation that called for a power-up. Plain old sword-swinging wouldn't be enough. All he's got easy access to is his Kick Strike ring, so he parries the incoming doctor-ghoul with his blade while he does a one-handed ring switch. Another slash, another hand motion, and he's activating his driver noisily.

"...yeah! It's me, Nitou!" Nitou's apparent regaining of sense gives him a burst of hope and confidence. He sets the ring, it calls out, his feet set on fire, and he does an impressive spinning roundhouse in an effort to destroy whatever ghouls are now trying to come in at them both.
