Many years have passed since humanity disappeared from Earth. At the Gingarou Hotel in Ginza, Tokyo, the capital of Japan, the hotelier robot Yachiyo and the other employee robots are waiting for the owner to return and for the time to once again welcome human guests. However, the first guest to arrive in 100 years was an extraterrestrial life form. The purpose of their visits one after another: to stay overnight, to invade, or perhaps neither... With the prestige of Gingarou on the line, Yachiyo and her friends' hospitality, is far from over. (Source: Takeshobo, translated)
