蜘蛛ですが、なにか？

I'm gonna survive, just watch me! I was your average, everyday high-school girl, but now I've been reborn in a magical world...as a spider?! Wait--this isn't how these stories are supposed to go! Can I get a do-over? ...No? But how am I supposed to survive in this big, scary dungeon as one of the weakest monsters? It's 'every spider for herself' in here! I gotta figure out the rules to this QUICK, or I'll have to kiss my short second life goodbye... (Source: Yen Press)
