I still don't understand what the hell is power is

Haze Blade spreads blades all around the air so small they're invisible to the naked eye. Think Senbonzakura but in a microscopic scale. The size makes it so Haze Blade ignores armor and barriers as long as it's not air tight. MC can shred anything by willing the blades to move in unison.

The weakness is it's vulnerable to wind changes, as a slight breeze can move it away from the intended target radius.

Oooo interesting thx
