From the Game's Introduction:
Pineapple Salad is a GM-less roleplaying game for 3 players. It is based on the popular anime subgenre in which a mecha pilot and a singer become involved in a love triangle against the backdrop of a military conflict. It is assumed that players are conversant with GM-less RPGs, scene framing, and polyhedral dice, and have watched a couple of episodes of Macross / Robotech.
The players will take turns framing scenes in which the active player's PC is the protagonist.
