The player's goal is to charm girls from National Star God Academy, raise their affection for Itsuki, then produce and take the Star Children to explore dungeons and battle Impurities. However, it is not an eroge, as the "Star Children" are produced by pouring energy from Itsuki and one of the twelve Star Maidens into a particular device. The child's class and statistics are determined by which character parents the child; for example, certain combinations could result in creating a warrior, or a child who specializes in magic. To produce more plentiful and powerful Star Children, Itsuki must increase his intimacy with the twelve maidens. The other aspects of the gameplay is typical to dating simulation games. The game operates on a turn-based battle system.
