The Battle of Sound and Storm

The old man snapped his fingers, and a guitar appeared in his hand. He played it, sending a dangerous sound arc towards Hijoto, but it could not penetrate the vacuum. 

The old man snapped his fingers again, causing the violin to disappear from his hand, and drumsticks appeared instead.

He then ran towards Hijoto, entering the area where the vacuum had been created, and started fighting him.

As Hijoto held his breath, he was unable to fight properly. He also could not dissolve the vacuum created; otherwise, the old man would use the sound effect again.

The old man used to go outside the vacuum, breathe there, and then come back again to fight him.

Since Hijoto couldn’t hold his breath for long and needed air, the old man’s attacks weakened Hijoto’s body as he tried to maintain the vacuum.

Eventually, Hijoto had to dissolve his vacuum to breathe, and the old man thought he could now defeat him with another sound attack.

He snapped his fingers again, and a mouth organ appeared in his hands. As he played it, large musical notes began to emanate from it, growing in size and flying towards Hijoto like bullets.

Those notes were very sharp. Hijoto tried his best to escape them, but some of them caused severe damage.

Hijoto already had ear pain from the previous sound effects. He realized that the only way to defeat the old man was to use thunder and lightning power which required a lot of strength, and Hijoto was already weakened.

Hijoto took a deep breath, raised both his hands, stomped his foot, and shouted, "Thunder Lightning – the Power of Blue!" and a bolt of lightning struck the old man, engulfing him in flames.
