Western Restaurant Nekoya is a popular eatery located on a street corner in a Tokyo shopping district. Serving both traditional Japanese fare as well as Western dishes, this eating establishment is popular among Tokyo's residents. But this seemingly ordinary restaurant is also popular with another type of clientele... While the restaurant is thought to be closed on Saturdays, the truth is that on this special day each week, its doors are instead opened to the inhabitants of other worlds. From dragons and elves to fairies and mages, this restaurant has no shortage of strange customers. Nevertheless, the enigmatic chef known only as Master will be waiting to serve up their favorite dishes with a kind smile and keep them coming back for many more Saturdays to come.

The Western Restaurant Nekoya is adored by its local Japanese clientele. The eatery's continued success can be attributed to its tasty western and Japanese dishes, as well as its cheerful head chef, Master Tenshu. In Japan, the restaurant appears to be closed on Saturdays, but in actuality, it is the one day that Nekoya transcends to the Other World and opens its doors to guests seeking foreign cuisine. From castles to forests, the Restaurant to Another World—as its patrons call it—travels far and wide. Nekoya's diverse and bizarre clientele can expect to be greeted by one of two devoted waitresses—the courteous demon waitress Aletta, or the enigmatic and elven Kuro. As customers, both old and new, pile into the establishment with stories of their respective lands, Master and his staff ensure that everyone is in for a scrumptious adventure of a lifetime.

A decade ago, a tragic shipwreck separated Fena Houtman from her childhood friend Yukimaru and took her father's life. Now, at age 23, she is trapped on an island and is doomed to spend the rest of her life selling herself to men. On the night she is to be forcibly wed to a client, Fena hatches a plan to escape from her employers, but two old acquaintances unexpectedly intervene and help her run away. The three make haste for the open sea and land upon Goblin Island—a mysterious place that a clan of fierce warriors call home. It is there that Fena learns that her father's ill-fated final journey at sea was in search of a place called Eden, the location of something important that he had to protect. With nothing but a clear crystal as a clue, Fena is tasked with finding this place, as she is the only person who can do so. While still contemplating the search for what her father left behind, Fena reunites with Yukimaru, who encourages her to take up the quest. Now the captain of a seven-person crew, Fena must navigate the high seas in search of Eden. But as uncanny groups begin to target her, the perilous journey proves to be even more challenging than it previously seemed.
