So I'm a Spider, So What?

The story begins with a typical high school day, but it's cut short by a catastrophic event that wipes out the entire student body. A few students are reborn into a fantasy world, assuming noble or royal roles, while one girl is reincarnated as a weak spider. Despite her difficult circumstances, she must adapt and survive in this new world, using its RPG-like system to hunt for food and battle monsters.
