A clashing sound!
Causing the distant skinny youth's expression to change greatly: "He stopped it!"
That was his trump card, one that he had trained long for, with comprehension of the wind origin laws, a move infused with wind origin laws to unleash its full power.
This Leaving Blade had the properties of the wind origin laws, its speed was extremely quick, it floated and arced about, its power was huge, it was his biggest trump card! During the training space stages, he didn't have any use for secret weapons, and later during the 3 round duels, his opponents werent enough for him to have to use it, hence it had been kept a secret til now,he had been preparing to use it on an unready opponent.
Trump card, they had the biggest power when unexpected.
Without preparation, it was easy to get hit!
The moment it was found out however, they would automatically have defenses for it, the trump card's power would be weakened.
