A space of three steps separated him from Kirei’s iron fists.

The Contender once again let out a furious roar. Kirei had no time to dodge, nor did he have time to draw his Black Keys.

But Kirei had never intended to dodge.

Kirei once again activated a Command Seal the moment he stepped toward Kiritsugu. He reinforced his physical abilities. Kirei accelerated his reaction time, multiplying the maximum power output of his right flexor, radius muscle, and pronator teres. There was no time to strengthen the sleeve of the bulletproof frock. The rest depended entirely upon his skill.

Kirei threw a right punch a moment before the Contender fired. His arm, having transformed into a lethal magecraft Mystic Code, carved a spiral through the air, and a tornado roared into being.

This movement became a spiral of force. Originally a defensive skill to nullify an opponent’s strike, the martial arts move was performed at a horrific speed after the prana of two Command Seals was infused into it.

The bullet left the barrel at a speed of 2500 inches per second, and was wrapped up in the spiral that moved at a divine speed. Even so, the .30-06 bullet still kept a straight path. It tore apart the Kevlar sleeve, clashing viciously with Kirei’s hardened arm, emitting alien sounds like the clash of two mill stones.

The scattering sparks seemed to distort the laws of physics; a supernatural phenomena where approximately 3000 pound-per-inch kinetic energy was forced to bend to the power of magecraft. A chill ran down Kiritsugu's spine as he watched the second Contender bullet's trajectory change. The bullet flew off at an angle, into the distance.

Monster. There were no other words to describe the man before him. At this moment, Kotomine Kirei’s current combat ability is equal to that of a Dead Apostle. Just what kind of willpower was required for a living man to drill his own body into such a terrifying lethal weapon?
