So I'm a Spider, So What?

The protagonist opens her eyes to find out she's been reborn as a spider. Which is already nightmare mode, before having to worry about cannibalism from other spiders, not the least of which being her mother! The story of a high school girl with nerves of steel and her struggle to survive in another world begins here!

The protagonist has finally created a home of her own, and begins to start fighting monsters in order to level up. Other than the nasty food, it's a fairly fulfilling existence. But things take a turn when humans show up. Her cozy little home is burnt down...

The protagonist has evolved into a higher-ranking species, which means having new skills and better stats. As she skitters through the labyrinth with little competition, she goes a little too far and finds herself in the lower layers where vicious monsters wander in droves, running into serious trouble.

The protagonist has managed to escape the threat of the Earth Dragon, and while she's a little frustrated about being forced to run, she decides to continue her journey. But in the Great Elroe Labyrinth, monsters prey on each other where only the strongest survive! And that means a new threat is already around the corner.

She's finally made her way into a new layer, but what the protagonist sees is a blazing subterranean inferno stretching out before her eyes! The spider webs that have been her bread and butter catch fire, and she can't survive a conflict with monsters that can swim in magma just yet. She decides to come back later, after achieving her next evolution.

The protagonist encounters a new monster as she makes her way through the magma-filled middle layers of the labyrinth. She finds herself outclassed in every category except speed, in a hopelessly one-sided conflict! Making use of her new skill, she searches for a way to turn the battle around.
