Let’s remember this is anime and a lot of nonsense can happen in a very shot period of time.
How long would a Hakai focused on Onigashima specifically take to destroy the island?
as a Point of reference Pica was cut in half and then bisected and then chopped into even tinier pieces and then his real body was defeated by Zoro in less time than it took for his pieces to even REACH anywhere near the ground. That’s Mountain level destruction over multiple attacks that happened in less than probably 30 seconds.
So how long would it take for one clean Hakai to destroy an island?
