This is a coffee shop where the "former demon king" invites you. An interdimensional labyrinth of gourmet food and love! --Five years ago, the Demon King died. In Tsukitaka City, there is now a retro coffee shop run by a strong-looking manager. The manager, Mr. Don, is a former Demon King. He and his part-timer, Touri, and barista, Yuu (*a former hero), keep the store running smoothly. However, the customers are all adventurers who come to the store with their troubles in tow, and the place of relaxation is constantly in turmoil, and the three shopkeepers are constantly getting involved! And the store manager's past becomes a disaster, slowly closing in on the town.
