The gameplay in Rui wa Tomo o Yobu follows a plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the five female main characters.

Rui wa Tomo o Yobus 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. There are five main plot lines that the player will have the chance to experience, one for each of the heroines in the story. To view all five 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 is for the player to enable the viewing of hentai scenes depicting the protagonist, Tomo, and one of the five heroines having sexual intercourse.

Tomo soon discovers that he is linked with five girls who are around his age as a second year high school student. These girls happen to have the same mark he has, and also have been going through hardships in their lives. Tomo and these five girls decide to form a pact to stay together and support each other to solve each of their problems and to bring peace to their lives. Though Tomo initially hides the fact that he is male from the others, the five girls eventually discover his secret.
