The game takes place in 2001, when the Japanese Empire's attempts to develop a next-generation Tactical Surface Fighter for their army had failed. To solve this problem, they decided to work with the American government to build upon their Shiranui, and the project was given the code name XFJ. A young officer named Takamura Yui is put in charge of it.

The gameplay involves making choices that affect the story and its multiple endings. The player takes on the role of various characters, including Takamura Yui, as they navigate through different situations and make decisions that impact the plot.
