It sucks that you must soldier on to get to the time skip, because the town in the mountain arc is really, really, really stupid.
Post skip it gives us some development sure but this shit really didn't need to be 57 volumes long what the fuck.
I've heard people compare this to Onani Master and honestly it's a frigging disservice to Onani to be placed anywhere near this.
I think the closing act is good, but this as a whole is not that good and it has its characters feel less like people and more like narrative devices.
