"Where The Stars Brought Us" follows the story of Ryo Yung, from Seoul, South Korea. He and his mother, father, and sister take what was meant to be a week-long trip to Tokyo, Japan. This begins Ryo’s many adventures.

His journey begins with the search of the Narusawa ice caves, where he meets Mae, a non-human girl with healing powers, and another odd being.
However, during that time, Ryo’s sister, Nam, has gone missing. Mae uses this opportunity to strike up a deal: she will help Ryo find Nam, if he helps her in return. Ryo agrees, and the events of the game are set in motion.
