Mysterious Mansion

Something a bit different than usual. Some variaton of an eroge I played many years ago (one of my first).

Plot :

Somewhere in Japan out of the big cities, by country side, is located a decent and old traditional onsen and inn, owned by a family through generations and generations. The Sadawa family had always been there. But this onsen is special and not quite easy to find. As a matter of fact, no guide, no books, no website is mentionning it. Mainly because you can't find what you're not looking for. You just encounter it, usually when you are lost physically and/or mentally.

The service given is not really like the others, let's say it, it's unique. They are only girls in it, all from the family, and they're not fierce. If you're totally lost, maybe your path will lead you to this place like no others.

YC can be several profile : young, old, poor, rich, attractive, ugly...it doesn't matter. But the opening will always start as YC wandering in the dark, a kind of thick fog preventing you to find your way. Until you spot the dim light of a lantern...and a big house slowly emerging from the darkness.
