Fang Xiaoluo is acknowledged by everyone as a beautiful girl, yet she has no interest in dressing up or shopping. Instead, she spends every day obsessed with tokusatsu shows, dreaming of becoming a superhero.
Of course, superheroes are fictional and don't exist, so she decides to take matters into her own hands and write herself into her novel. There, she gets a transformation belt that transcends every dimension and can turn her into any superhero from any tokusatsu work, past or present.
Naturally, a novel like that is bound to flop. Nobody reads it. But Fang Xiaoluo writes purely for her own enjoyment, just for fun, and quietly finishes it even without readers or tips.
Unexpectedly, after she dies, she is reborn with her memories intact. But it seems she has been reborn in a parallel world, one where superheroes exist and monsters and kaiju that once appeared only in fiction run rampant. At the same time, the all-purpose transformation belt she created in her previous life has somehow fallen into Fang Xiaoluo's hands.
Naturally, Fang Xiaoluo transforms into the superhero of her dreams, fighting monsters with one hand and charming beautiful girls with the other. She gets to live it up as the ultimate heroine!
