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!
”
— Official synopsis of Volume 1
The Light Novel adaptation of Kumo Desu ga, Nani ka? Volume 1 was released to the public on December 10, 2015, in Japan. It retells the Web novel's story with some slight differences, the most notable change being the introduction of Feirune. It also contains the side stories just like in the original Web novel.
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!
The anime adaptation of So I'm a Spider, So What? started airing on January 8th, 2021, for 25 episodes. Its director is Shin Itagaki, and it's written conjointly by Okina Baba and Yuichiro Momose. Exsa, with additional support from ENGI (Uzaki-chan Wants to Hang Out!), handles CGI production and Millepensee (Wake Up Girls! New Chapter, Cop Craft) is in charge of animation. Crunchyroll holds the license for overseas streaming of this series.
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 be kissing my short second life good-bye…
