She Transmigrated into a Book as the Villainess, Then Joined the Hero’s Party Without Hesitation

[Backrooms fiction + infinite-flow + transmigrate into a book + strong female lead]

By accident, she “clipped out” of reality and fell into another dimension of the world: the Backrooms.

What’s more, everything here was exactly like the world in her novel. And she had transmigrated into the role of Luo, a nonhuman, highly intelligent Entity who was a cannon-fodder villain and an undercover mole in the protagonist’s group.

The first time, she followed the plot as written.

She did every terrible thing imaginable, had her identity exposed, and was killed by the heroine, completing her mission. But when she opened her eyes, she had somehow been reborn at the beginning of the story.

The second time, she turned and ran.

What a load of nonsense! She’d go retire in a level where no one could find her! Instead, the villainous BOSS caught her and mercilessly killed her.

The third time, she took her work seriously.

She grew stronger and built up her own forces, facing the protagonists head-on in the final battle, but still couldn’t overcome the power of “fate.”

The fourth time, she plunged a knife into the heroine’s heart. Then came the familiar rebirth.

The fifth time, she rushed the heroine through the levels at top speed. But deprived of the chance to grow, the heroine was scared to death by the weakest little monster. Reborn.

The sixth time... Reborn.

After trying a hundred different ways the plot could go, she realized there was only one way to survive: cling to the protagonists’ coattails.

She couldn’t reveal her true strength, yet had to keep the heroine alive; she had to stay on the side of the good guys, while also fending off the villainous BOSS’s “inspections”...

She sighed up at the sky: She’d transmigrated into a top-tier Entity in the Backrooms, second only to The Outcast and above all others, so why was simply trying to live a decent life still so hard?

(The overall worldbuilding is based on the W version of the Backrooms, with some original elements that will be introduced gradually. The story focuses on plot and requires no prior knowledge.)
