Tokyo, there are too many defeated magical girls.

Fortune favors the bold.
Having transmigrated to Tokyo in a parallel world, Lin Chun joins an evil organization.
Under the guise of a "brainwashing department," they were frantically swindling funds while preparing to abscond with the money.
But just before he was about to retire with his success...
The evil organization finally defeated the magical girl and sent her to their "brainwashing department" as an experimental subject.
