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!

I, the protagonist, was just an ordinary high school girl, but suddenly I was reincarnated as a spider monster in a fantasy world. Not only that, but I awakened in a dungeon filled with vicious monsters. Armed with only my human knowledge and my overwhelming positivity, I'm forced to use spiderwebs and traps to defeat far stronger monsters just to stay alive...
So begins the labyrinth survival story of a girl with incredible mental strength living as one of the lowest-ranked beasts!
