Akaneiro ni Somaru Saka's gameplay requires little interaction from the player as most of the duration of the game is spent simply reading the text that appears on the screen which represents either dialogue between the various characters or the inner thoughts of the protagonist. Every so often, the player will come to a point where he or she is given the chance to choose from multiple options. The time between these points is variable and can occur anywhere from a minute to much longer. Gameplay pauses at these points and depending on which choice the player makes, the plot will progress in a specific direction. In the original version, there are six main plot lines that the player will have the chance to experience, one for each of the heroines in the story. This number increases to seven with the PlayStation 2 version.[1] To view all the plot lines, the player will have to replay the game multiple times and make different decisions to progress the plot in an alternate direction. One of the goals of the gameplay from the PC version is for the player to enable the viewing of sex scenes depicting the protagonist, Jun'ichi, and one of the six heroines having sexual intercourse.


Jun'ichi Nagase attends a prestigious high school. He has the nickname Geno Killer since he was rebellious in middle school. This is used, inadvertently, to help a girl named Yuuhi Katagiri from trouble. She later transfers to his school, and in order to protect Yuuhi from danger, Jun'ichi is forced to kiss her. Not understanding what happened, she screams at him. Subsequently, it turns out that Yuuhi is his fiancé as arranged by their parents. Their parents discuss the matter and order them to go out together for a month to restore their relationship. If their relationship does not get better, the engagement will then be canceled.
