Plot
In the year 2057, an unknown aerial contagion dubbed "infortunium pollution" begins to spread around Earth, rendering the air unbreathable to primate-based species, including humans. With no way to cure or counter the infortunium pollution, humanity has no choice but to flee to space, leaving the planet completely abandoned. A century later, the only sign of civilization left is the Gingarou Hotel in Ginza, which is kept operational by what remains of the autonomous robot staff led by the gynoid concierge Yachiyo. As the staff wait patiently for humanity to return, they are caught off guard when their first guest to arrive in a century turns out to be an extraterrestrial visitor.
Later a family of tanuki aliens visit the hotel after fleeing their home planet due to a war. This family end up living on Earth in their converted space ship, and one of the tanuki, Ponko, becomes an employee at the hotel. The tanuki have long lifespans, and together with Yachiyo, they work together to improve the hotel and attract more alien visitors over the course of several centuries, but still waiting for humanity's return. These improvements including building a hot spring spa, constructing a distillery to make their own whisky, and promoting the hotel by launching adverts in space.
Eventually, a human named Tomari Iori visits Earth, having been raised on a spaceship.
