Episode 1

In 2157, infortunium pollution has made Earth’s air essentially unbreathable, prompting humanity to flee toward space shelters while Gingarou Hotel remains ready for its return. With no guests and its owner preparing to leave, the hotel’s robots maintain inspections, service routines, and the daily creed under the acting acting manager. After Driller Robot becomes inoperative, the manager plans to handle drilling at the hot spring site herself rather than assign it to Doorman Robot.
