Short description
An erotic fantasy visual novel from the twisted mind of Sei Shoujo of Bible Black fame. A pair of college students wanders into Black Rose Manor, an isolated estate located deep in the mountains once again.
About this game
Artist and writer Sei Shoujo's erotic talents are on display once again in the sequel to SLEEPLESS - A Midsummer Night's Dream , SLEEPLESS - Nocturne ! A pair of naive college students, Kawai Tomoki and Komori Yukino, are out on a date which is interrupted by a sudden car trouble. When the young couple abandons their vehicle to find help, they find themselves at the door to the Black Rose Manor. The dazzling Mamiya Marie, mistress of the estate, graciously invites them into the lavish splendor of the mansion where they are greeted by Aria, the estate's stoic, yet alluring maid, Maria, Marie's gorgeous daughter, and most mysteriously a pink-haired, cat-eared girl in a collar who introduces herself as Takamizawa Rui. As the couple decides to spend the next few days at the isolated estate, are they prepared for the debauchery that awaits them...? The erotic mastermind behind Bible Black and STARLESS (just to name a few!). Reprising his role as both artist and writer for the sequel, Sei Shoujo once again demonstrates why he has earned his legendary reputation as an erotic artist. Twice As Nice? Both protagonist Tomoki and his girlfriend Yukino entering the mansion together opens up a novel array of indecent opportunities to enjoy. The cast of the previous game, SLEEPLESS - A Midsummer Night's Dream, returns for more!
