Kurokami Phantom

Kurokami Phantom (黒神ファントム, Kurokami Fantomu): Is a basic skill used by members of the Kurokami family. It is a skill that lets the user move at an extremely high speed, if not conceptualize greater idea's.

Overview
One of Serizawa's signature moves, he first jumps up and down, dragging out the noise so that the sound of his feet tapping on the floor isn't heard until after her feet have left the floor again. Once the sound lag is at its fullest, Serizawa blows forward, producing a sonic boom that destroys everything in his front of and behind her. Because he moves faster than the eye can see, the opponent won't be able to react until after he has already hit them. The technique itself destroys the concept of speed and replaces it with a greater idea which is up to the users own creation.
