The Great Jahy, the Dark Realm's second-in-command, cuts a frightening figure, feared and revered by all. But when a run-in with a magical girl results in the destruction of the precious mana crystal, the Dark Realm falls, transporting the newly tiny and powerless Jahy to the human world! Unfortunately, plotting the revival of the Dark Realm from a cramped, crumbling one-room apartment is no easy feat when you have rent to pay and a job to keep!
