Kakyūsei 2 is a dating sim and the sequel to 1996's Kakyūsei, itself a spin-off of the Dōkyūsei series.

The player is placed in the shoes of a student (default name: Oriya Rouma) during his last year of high school, as he is trying to find a girlfriend before graduation. Over the course of the story, he meets and bounds with nine eligible bachelorettes from his school, and can eventually chose to romance one of them.

Much like its predecessors, the gameplay centers around Oriya exploring his school, his local neighborhood, and the city, during which he can enter restaurants, shops, cafés, houses, etc. and potentially encounter the nine dateable girls and learn more about them through having conversations with them. The nature of these conversations usually depends on which location the girl is found at in and tends to feature multiple answers; in most cases these answers will either advance or hinder the progression of the relationship with the girl in question depending on the player's choices, leading to new story events. The game also features an internal clock and calendar, with some events, such as holiday celebrations or birthdays, only happening at certain times or on certain dates.

These two systems often times interact, with information given through conversations becoming relevant later down the line - most prominently, the girl in question can give a hint to their tastes in gifts, and if the player later gives them their desired item on their birthdays, it will greatly increase their approval of you.

Also like its predecessors, the game features scenes with nudity and explicit sexual situations.
