オイランルージュ －花魁艶紅－

After his father’s sudden death, Kamon was forced to take over the family brothel Takaseya in the red light district of Yoshiwara in Edo. However, the debt collectors soon found out that the business had been passed on to someone who was inexperienced and came to take everything away. With the intervention of the local boss, he was able to keep the building which was now low on reputation, one lone tayuu Hisasa and several lower-grade courtesans, a handful of money and a girl that his father had picked up from somewhere, Amane. He decides to work hard to become one of the top tourist destinations in town.
