She got trapped in a trashy game and ended up with the worst possible ending.
Funes was once a wicked witch in a parallel world, but now, in the surface world, she's just a frail, beautiful girl confined to a wheelchair.
No matter. Things can still be turned around.
The parallel world is about to descend upon the surface world in the form of dungeons. Funes will enter them as a New Game Plus player, speedrun them all, and restore the witch's glory!
That was how it was supposed to go, anyway.
Funes used her beauty and emotions to deceive and toy with the heroines, and made others submit with her straightforward displays of power. Now, the past has come back to bite her.
In the dungeons, the heroines give Funes a taste of her own medicine, subjecting her to all kinds of bizarre revenge.
Back in the real world, the heroines are gradually regaining their memories, approaching her and doing even more outrageous things.
In the end, even the younger sister Funes raised herself has turned dark without realizing it, becoming increasingly obsessive toward her...
Much later, surrounded by a crowd of women with nowhere left to run, Funes declares victory.
“I’m going to win!”
