Kai is a character in Harvest Moon: Back To Nature. He is also an eligible bachelor in Bokujō Monogatari: Harvest Moon for Girl. Kai visits Mineral Town in the Summer to operate the Seaside Lodge. He is quite the "ladies man" and often comes across as condescending to the male villagers. He means well, and feels misunderstood by others because of his care-free attitude. Kai visits Popuri during the Summer, which causes an argument between him and Rick. Kai and Popuri may eventually marry in game. If they do, Popuri will leave with Kai and only return during Summers.
