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.

Simulation:

There are two difficulties:
Casual mode: There is no ongoing debt. You can outshine the competition eventually in a debt-free situation.
Normal mode: There is a monthly debt to be paid. The brothels are in danger of closing if the reincarnator's brothel continues to attract your customers.

H Battle:

Simple control to let you in the brothel:
You will get a battle rank for ladies satisfaction when you win the H battle.
Rank A: satisfaction over 100%, is a good play.
Rank S: maybe can get some extra present?
