Grandson's Mysterious Superpower

Finally, Grado inadvertently let go of Satoshi's shoulder as he walked forward. He assumed the position on one end of the field before turning around to face his grandson. On the other hand, Satoshi had no idea what his grandfather was doing, but he stayed in place. He figured that his grandfather most likely had a surprise for him or something of the sort, and that's why he was acting weirdly.

Flashing a smile at Satoshi, Grado then manifested a condensed ball of air in his hand, shooting it high up in the air. Once again, the orb of air went up, exponentially increasing in size as it rose higher. The moment it reached its peak, it covered the entire field where Satoshi and his grandfather were in. While it kept them shielded from outside forces, it also protected the house from the two of them. This also blocked all the noise coming from either side of the wind territory.
