If all physically possible universes exist, so do all physically possible girlfriends… including the one you're imagining who's imagining you. Ana's parents, who hadn't heard that it wasn't game-theoretically optimal to punish her for dropping LSD, packed her away to a troubled teen camp. During the day, Ana faces the harsh Utah desert, near-starvation, and torture in the name of "therapy." At night, she seeks desperate comfort in the arms of her alternate-universe girlfriend, Yuya, one of three hundred wives in the harem of the Emperor of Every World. But as their respective prisons wear away at their very selves, both girls face a choice: to become the monsters those in authority want them to be, or to die trying to escape.
