Overworked office employee Seiichirou Kondou would be fine spending the rest of his days in the same exhausting routine, but an unexpected act of heroism causes him to be sucked into a parallel world. His abductors, residents of the magic-filled Romany Kingdom, promise him a life of comfort as an apology for his accidental summoning. Unfazed, Kondou demands something that he thinks would suit him better: a job.

After witnessing the incompetence of his new colleagues in the Royal Accounting Department, Kondou's workaholic instincts kick in, and he takes it upon himself to save the kingdom from complete bankruptcy. But this new world proves detrimental to Kondou. When the young and dashing captain of the Third Royal Order, Sir Aresh Indolark, saves Kondou's life, the two become something more than acquaintances. Though Kondou and Aresh initially struggle to convey their clashing values to each other, they slowly realize that this meeting will not only change their own lives but also the kingdom as a whole.
