The primary objective of this game is to plan training schedules for yourself and the four members of your party, including you, to strengthen them. You must win several board game battles that occur during the journey. Additionally, by forming close bonds with the girls you recruit as allies, you can receive a confession of love from them in the ending (if you fail to build a good rapport with any party member, you will receive a confession from one of the rival characters, Kyle, Remit, or Iris). These romantic elements are secondary objectives. There are a total of 27 different endings in the game.

This game can be considered a precursor to MediaWorks' Yuukyuu Gensoukyoku Series.
