Amy, the super-powered 100th-generation heir of a talisman-making family, just wants a normal life. That's too bad, because her chaotic best friend, Joshua, convinces her to try a ridiculous experiment: slapping a super-lucky talisman on a ghost.

Instead of disappearing, the ghost transforms into a gorgeous, living person. Seeing a golden opportunity, Joshua starts a "ghost rehabilitation service," asking Amy for more talismans. Amy thinks Joshua is building a weird ghost harem, but his actual plan is even crazier: he's creating the world's first J-pop idol group made entirely of magically transformed ghosts. Now, Amy is stuck as the reluctant magical engine behind the weirdest musical act in history.
