The player plays as Io, an ordinary boy with a tender heart, whom village elders force to "go on a journey" to save the world from disaster. Io, although ambitious, is scared to talk to girls in fear of them labeling him as a pervert. Crises are occurring all over the world at the beginning of the game, and "monster girls", which inhabit it, have suddenly become hostile to humans, with a "legendary monster girl" thought to be the cause.
