A girl reincarnated as a spider in a dungeon full of things that want to kill her learns that survival is just another problem to solve with the right attitude. She doesn't cry about being weak, she gets smarter, meaner, and funnier as the stakes climb higher. The CGI gets rough when the budget runs out, but the core story, watching someone build themselves from literally nothing, stays sharp enough to pull you through.
A Japanese high school girl opens her eyes in a dark dungeon with eight legs and silk-spinning abilities. She's been reincarnated as a spider, one of the weakest creatures in this fantasy world, and she's trapped in a monster-filled labyrinth with no way out. Rather than despair, she leans into her new biology: spinning webs, setting traps, and using cunning to survive encounters with far deadlier predators. Each victory brings experience points and evolution, gradually transforming her from prey into something fiercer. Her human mind and stubborn optimism become her greatest weapons as she navigates a hostile environment where death lurks behind every corner. The story swings between laugh-out-loud moments as she names spiders and celebrates small wins, and genuine tension when a powerful monster corners her in a tunnel. She studies her enemies, experiments with her abilities, and slowly carves out a place for herself in the dungeon's ecosystem. What emerges is part survival thriller, part comedy, part fantasy power fantasy: watching an ordinary person adapt, strategize, and claw their way toward becoming someone extraordinary, all while dealing with the absurdity of being an arachnid.
