Nocturnal Illusion

Synopsis

Nocturnal Illusion is a Japanese bishōjo eroge, developed by Excellents Japan. The player character, Shinichi Kashiwagi, is lost. Dissatisfied with the direction his life is talking, he decides to get away from it all during his spring break and stay in the mountains in order to find himself. Towards the end of his vacation he's made little progress when he is caught unprotected in a typhoon, and blown over a steep incline (losing consciousness). A mysterious woman saves him and uses sexual pleasure to keep him warm. It turns out that he is now in a mansion that is outside of regular time and space, with a gate that only opens when it chooses (while not explained who does it, food and such necessities are left at the gate by some unknown force). The woman who saved Shinichi is the mistress in charge of the place. Shinichi explores the mansion and meets many women, which leads to sexual experiences with all. Many other people live there, but no one can seem to answer any questions about the mysterious place. Shinichi tries to leave, but can't open the gates. The mansion holds everyone captive. The others have given up; they are resigned to staying at the mansion for eternity. At the end of the game, the gate opens and Shinichi can choose either to stay or take one woman out of the mansion.
