So I'm a Spider, So What? Light Novel

A high school girl wakes up reincarnated as a small spider in the worst dungeon imaginable. With no rules and no safety net, her only option is to fight, eat, and evolve her way through a world determined to kill her.

Fresh off a string of victories, the spider's overconfidence leads her into an unexplored area where she comes face to face with a massive dragon — arguably the dungeon's most fearsome resident.

After crossing the dungeon's deadly magma sea, the spider now faces the earth dragon Araba — practically the king of the entire Elroe Labyrinth. Her chances look slim, but then, they always do.

The spider finally escapes the monster-infested labyrinth and heads for the surface — only to find something even more terrifying waiting for her: Mother. Their relationship is complicated, to say the least.

With the battle against Mother behind her, the spider turns her attention to preparing for the Demon Lord. But she's gotten too strong for her own good, and all the unwanted attention that comes with it is forcing her to interact with humans for the first time.

Evolution achieved — she's finally an Arachne. Somehow, this leads to joining up with the Demon Lord, traveling alongside the lord of demons and a vampire princess. She'll worry about what that means later. First: the human world.

A seemingly justified act of self-defense against attacking spider-monsters turns out to have been loud enough to wake ancient, unmanned weapon systems. Now robots and tanks roam the land, and no one knows what to do.

Stripped of her skills and stats after deification, Kumoko is reduced to luggage status — and her timing couldn't be worse. The Demon Lord's party is about to be attacked by a reincarnation who has become a demon berserker.

Confined to a demon's mansion while waiting for her powers to return, the spider eventually discovers they've come back — along with an unexpected talent for teleportation. That gives her an idea: it's time to meet D face to face.

Having pieced together why she was reborn in this world, the spider focuses on regaining strength and new skills, deploying thousands of spider agents across the globe to keep watch. Turns out she has a gift for espionage.

What does it mean to be a Hero? Chosen by the gods and burdened since age six with the duty to defend all humanity, the Hero reflects on early failures and the friends who make the mission feel possible.

The Demon Lord launches a massive assault on the fortresses guarding the human frontier, committing hundreds of thousands of soldiers. The humans mount a stiff resistance — and the spider reports from the front, right in the thick of it all.

Even becoming a god doesn't simplify things. After eliminating the Hero title by hacking into the world's System, a new one is inherited almost immediately. Now the other reincarnations are converging on the elf village just as the demon army prepares to conquer it. Time for Plan B.

The final confrontation with Potimas looms, but so does an inevitable clash between the reincarnations. With factions colliding and old grudges boiling over, the spider just wants everyone to get along long enough to deal with the real enemy.

With Potimas finally out of the picture, the path to destroying the System seems clear — until D activates a World Quest that reveals the fate of the world to its entire population. Now everyone must choose a side: Black or White. Either way, casualties are guaranteed.

The final question: sacrifice the goddess to save humanity, or sacrifice humanity to save the goddess? With the Word of God religion backing one side and the spider and Demon Lord backing the other, the grand finale is here — and D is content to watch it all unfold.
