Kounai Shasei Vol.1: Yonimo H na Monogatari

"Kounai Shasei 1" opens with a text introduction that describes a miraculous Girls' High School that can be accessed by sailing through the Indian Ocean or walking along the Silk Road - a school that even the famous Marco Polo allegedly describes in his memoirs. This establishes the humorous tone of subsequent narrative, which has little to do with history and a lot to do with pretty high school girls. The game has no real story, being instead composed of five unrelated vignettes, short episodes that feature a sexy high school girl, a male protagonist (named "God" by default), and various comical and erotic situations under different circumstances: meeting in a school, haunted house, crowded train station, etc.
