Is it just me, or shouldn't it be obvious by now that most mangas translated from novels follow the light novel, not the web novel? I mean you can probably count how many mangas follow the wn over the ln on one hand at best.
I really enjoy this turn of events!
It also sets the Alaba fight in better perspective for me, seeing that there is still a lot of stuff Kumoko can struggle with if she isn't prepared enough. The Alaba fight was a bit too much keikaku doori for my taste.
@Kaarme the spider girl is attacking the mother's soul with her extra personalities and since she got a soul that can't be harmed the only way to fight back is to kill the original body.
@Kaarme You're not seeing the whole picture, Mother wants only the strongest to survive, however Mother is not stupid, one of her kids seems to have become far too strong and evolved to an unplanned transformation. Kumoko's evolution is incredibly uncommon, her new race is something you'd only hear in legends and while well known, such a race is not supposed to exist. The descriptions of said race already state this. There's a reason as to why these spiders are never seen, but that'll be explained later.
