To be at its core a conversational simulation and an interactive story, the game follows the usual standards, offering little innovation outside the combat system. It is a fairly long game, with the classic replay of these products, which is based on choosing a different male character to approach more to change the story protagonists.

The game is full of simple conversations but a battle system is presented where two shiny spheres rotates around a ring. Locations on the ring indicate the cue points on which to tap in order to trigger a sword strike by one of Mariko's allies. Botch the cues and suffer from missed chances as well as the thunder from retaliatory attacks. The battle can be fought on any of the characters at the player's choice.

There is another important choice given to the player from time to time, and which serves to enhance her relationship with one of the male partners, since it allows her to choose one before the start of each episode of the game. This, together with the other choices the player will make during the game will determine who the player ends up with by linking them more, like typical Japanese Otome games.
