You are Shinichi Kashiwagi. A young man that is popular around women, but unfortunately you have no steady girlfriend. You decide to out into rural Japan to reflect on your life. However... You get caught up in an unexpected typhoon (which hit a day earlier than expected) and nearly die. Fortunately, you are found by a mysterious woman who calls herself "the Mistress of the mansion" and she "pulls you back in the direction of life." Now your only challenge is to survive in the amazing, yet dangerous, Mansion of Illusion, which has been rumored to only appear to "special people"; in other words, you got lucky stumbling into the mansion...... but how do you escape? The gate won't open for you no matter how hard you push or pull, and there's no other exit.
During your random adventures around the mansion, you meet many different people (primarily women), and you help them all out with their own personal problems in their lives, trying to steer them in the right direction. In the end, after all is said and done, and when the gate opens for you, will you really want to leave all the people behind forever?
This is a rather old game and plays on Windows95. It is one of the earliest translated H games out there. I haven't tried out this game myself yet, so I don't have any first hand experience but some of the elders here might. I couldn't find this game on the Master List so I figured I might as well share it here.
Anyways, this download includes a patch fix for the game. Enjoy!
