With a loud voice, the King of Knights commanded the noble holy sword.

"Strike Air!"

In the middle of the whirling air, the resplendent brilliance of gold shone through.

The sheath of super-high pressured air that protected the holy sword was released from the bondage of the invisible barrier – bellowing forth like a savage dragon's roar.

The secret sword technique that guaranteed the kill. It is a different way to use the Noble Phantasm Invisible Air. Last night in the battle against Lancer she released this extreme air pressure to accelerate quickly. If it was released towards the enemy it would become a tempest, a crushing hammer that blows away entire armies.

Thoughtlessly packed together, the demonic beasts took the blow all the harder. The super-high pressure tempest, compacted like a solid force, smashed the demonic monsters to smithereens, mixing the minced flesh together with gravel and broken wood. It was as if an invisible giant hand swept across the entire earth and opened up a dead straight path. The instant they were blown apart by the air pressure, a perfect hole appeared in the demonic monsters' ranks.

The destructive power of Strike Air was countered by the many layers of demonic monsters, reduced to a strong gust of wind that merely blew at the ends of Caster’s robe when it reached him.

The penetrated gap would serve as a path. However, against the density of the demonic monsters summoned, it could only count as a temporary opening that could be sealed off immediately.
