[@Saltwater Thief]

Just saying your ability is also canon. 

Not to mention the fact that the ability lets a blade cut through a whole tree and boulder with hardly any resistance.

I think that, Had Asuma survived his encounter with the Hidan and Kakuzu I think his ability would have been instrumental when it came to fighting the god tree and ten tails...

I think the ability you have chosen is also very powerful so.
