Fortune Arterial

The gameplay requires little interaction from the player as a majority of the game is spent simply reading text that appears on the screen. This text represents either dialogue between the various characters or the inner thoughts of the protagonist. Every so often, the player will come to a "decision point" where they must choose from options that are displayed on the screen, typically two to three at a time. During these times, gameplay pauses until a choice is made that furthers the plot in a specific direction, depending on which choice the player makes.

There are five main plot lines that the player will have the chance to experience, one for each of the heroines in the story. In order to view the five plot lines to their entirety, the player will have to replay the game multiple times and choose different choices during the decision points in order to further the plot in an alternate direction.

Fortune Arterial's story revolves around the male protagonist Kohei Hasekura, who transfers into a prestigious public school in the style of a Western six-year school encompassing junior-high and high school students. The school, named Shuchikan Academy (修智館学院, Shūchikan Gakuin), is on an island named Tamatsu Island (珠津島, Tamatsushima) off-shore from mainland Japan, and the only way to get there is by boat. Soon after transferring, he discovers that one of the students in the class next door to his, Erika Sendo, is in fact a type of vampire.
