The Lord of Isekai Brothels

In Free City, a famous red-light district full of brothels with a variety of races attracts both locals and foreigners.
Suddenly, due to the opening of a competing brothel that provides new and innovative sexual services, the old brothels find themselves nearly out of business. The new brothel is run by reincarnators and the red-light district must find a way to survive its competition.
The goal of the game is to unify all the brothels and manage a better business than the competing reincarnator’s brothel with cheat-like otherworld knowledge.​
