One day, a high-school girl known only as "I" is caught in a massive explosion in her classroom. When she wakes, she finds herself in a fantasy world crawling with monsters — and reborn as the weakest of all species, a spider monster. All around her are creatures far stronger than herself, and she was born deep inside a huge dungeon teeming with vicious beasts.
Armed only with her knowledge from her human life and an abnormal amount of positivity, she uses webs and traps to take down foes far above her level, grinding her way up as she desperately survives.
Airing across two consecutive cours from January 2021, produced by Millepensee. With Aoi Yuki playing what feels like a one-woman ensemble, this hilarious yet nail-biting dungeon survival of a mentally unbreakable girl begins. 🕷️
