Baek Juho used to be an executive in an evil organization. Not a particularly impressive one, mind you. His former employer, Wolgwangdan, was practically a joke, and his biggest accomplishments included avoiding Shining Star and stealing her deliveries.

Then the organization fell apart, leaving him unemployed and broke.

Half a year later, Gold Lion, also known as Hwang Geumhee, tracks him down with an offer he can't afford to refuse: restore Shining Star, a magical girl who has lost her powers.

Juho may no longer be a villain, but he knows a thing or two about magical girls. And as it turns out, getting one back on her feet takes more than a pep talk.

After an unexpectedly successful first assignment, he's officially put in charge of managing magical girls. Unfortunately, his new job comes with a rather troublesome roster: girls with broken confidence, complicated pasts, and problems that don't always have an easy solution.

His next case is Cotton Star, a fourteen-year-old whose neglected childhood has left her dangerously attached to the few friends she thinks will never abandon her.

Juho used to work for the forces of evil. Somehow, looking after a bunch of hopeless magical girls is proving to be a much harder job.
