In this free city, there is a brothel lined with brothels for each race, and customers of various races come from inside and outside every night.
One day, the economy of the prostitute is tilted by a new store.
The owner of that store is a reincarnated person. It provided unimaginable sexual services to other races.
In order to survive, each brothel will put together the brothels of various races, and in the management of the brothel, win the shop of the reincarnated person who has "knowledge of another world" and "reincarnation privilege".
