Kumo desu ga, Nani ka?

The last thing that a high school girl remembers is a strange explosion ripping through her classroom. In the aftermath of the tragedy, she finds herself reborn as a lowly spider hatchling, one amongst thousands in a vast cave. Furthermore, the world she is reincarnated into is a point-based skill system, prompting her to level up as quickly as possible if she is to survive the treacherous environment and persevere in the face of insurmountable odds.

Thus begins a little spider's journey of clawing, biting, and plotting her way to the top. Forced to confront the powerful beings that reign over the Great Elroe Labyrinth and beyond, she will gradually uncover the truth behind the mysterious fantasy world and the explosion that sent her there.
