“Time Alter: Triple Accel!”
Kiritsugu leapt toward Kirei as he uttered the forbidden spell. His unpredictable acceleration caught Kirei off-guard. One blow from the hardened walnut wood snapped Kirei’s right radius and ulna. The Executor's right arm was destroyed.
As he struck with his right hand, Kiritsugu drew the dagger by his waist using his left. With one eye and one arm ruined, it didn’t matter how great Kirei’s martial art skills were; victory would belong to Kiritsugu as long as he continued to move at three times his top speed. Using Innate Time Control in this way would ordinarily be suicide, but thanks to the protection of Saber’s sheath, he could now use it to its full potential as a strategic weapon.
Kirei dodged the upward stab as the dagger was removed from its sheath, and used his left arm to block the downward slash and backhand horizontal swing Kiritsugu followed up with. However, with these three attacks, Kiritsugu shifted around to Kirei's left hand side, into Kirei’s blind spot. As long as he stayed on the left side of the enemy, Kiritsugu would have all the chances in the world to strike Kirei down from his blind spot.
Kiritsugu’s sharp blade sliced closer, but Kirei didn’t turn; instead using the left side of the body to block every swing. Turning would have been pointless; his broken right arm could not possibly block Kiritsugu’s dagger. Thus, though it disadvantageous for Kirei to use his left side to defend himself, he had no other choices.
The dagger attacked continuously, flickering through the air with a chilling light. No regular human would have been able to even see Kiritsugu’s movements; only the lighting-like residual images the dagger left in its wake. Kirei, though, blocked every attack using just his left arm. Kirei, who easily defended himself even when faced with attacks made at three times the speed of normal humans, terrified Kiritsugu. There were a few attacks that even Kirei would never have seen coming with his eyes, but the Executor’s left arm defended him, as if it could see every swing.
“Could this be the idea of ‘hearing’ a move?!”
Kiritsugu only had a vague impression of this phrase. Some schools of martial arts thought that when a martial artist had reached a certain state in his skills, he wouldn’t need eyesight to detect the enemy’s movement. He could predict the opponent’s next move purely on the brief moment when his arm blocked that of his opponent.
The attacks from his blind spot had also been rendered pointless, then. Since the attacks were coming from a static location, Kirei could block them even if he couldn’t see them. This man’s skills made him someone who wouldn’t be at a disadvantage even when put under the duress of speed.
