Frankly even if most people say that, I don't see how more powerful it can get. The swiped area is too imprecise, it's not like he can shut wounds.

Only things I can think of is that Okuyasu can legit fly if he continuously swipes above his head. Or that he could use his swipes as some catapult, but what is the point since The Hand should be strong enough to throw things?

His power is pretty inconsistent anyway. One time is shuts the erased space, another time it doesn't.
