I just want to say, MC has gained no new powers since the beginning of the story... he was supposed to be "powerless and weak" but actually had all these powers all along? Kinda feels like the author is just making this up as he goes along...
Did you forget how and why he can use these powers now? The whole two chapters dedicated to him acquiring the ability to channel the powers of ghosts with the armbands?
Like there's some points of bad writing in the story, but this isn't one of them. There was set up in him acquiring this ability, hard downsides established, and him refusing an opportunity to potentially shackle his ghost family in order to have more permanent use of their powers.
I will sound horny and probably retarded, but I miss the perverted chapters. Half the cast is decently small breasted, and there was over-knee socks too, but this latest ark is pure fight no sex and its kinda getting over-the-top and boring to a degree. So I hope that we will get more sex than before to like compensate for this
