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 high school girl wakes up in a dungeon to find she has been reborn as a spider, one of the lowest and weakest monsters in a fantasy world. She and her classmates died when a clash of magic between the Hero and the Demon King tore across worlds and destroyed their classroom. A few of the others were reborn into privileged lives as nobles and royalty, but she has to fight just to stay alive in a labyrinth crawling with vicious creatures. Rather than despair, she uses webs and traps to bring down monsters far stronger than herself. Her world runs on RPG-style rules, so each kill helps her level up and evolve. Her human knowledge and relentless positivity become her best tools. Mixing action, adventure, comedy and mystery, the story watches a weak beast grow stronger while hoping for a better life.
