For me , this story suffer from being a prequel, it being a prequel meant that basicly everybody had to die but the last mc, so we spend 5 volume on 5 guys ( the first mc , the crazy girl, the spider guy, the sister and the dad) and half of them get killed off in one or two chapter, you see them for a couple of page after the time skip, you get a really vague sense of how time changed them and i mean realllllllllyyyyyy vague and after that it’s the fight then a small sad farwell and then hop hop hop , it’s time for an other, and to me the worst is the crazy girl , (yes i d’ont remember any names) the main guys aren’t even there for her death
