So I´m a Spider, So What? Vol. 1 (manga)

I used to be a normal high school girl but in the blink of an eye, I woke up in a place I´ve never seen before and-and I was reborn as a spider?! How could something that´s nothing more than a tiny spider (that´s me) possibly survive in literally the worst dungeon ever? Are there no rules? There should be some rules! Who the hell is responsible for this? SHOW YOUR FACE!
