Life changes for fourth-grader Koichi Uehara when he picks up a fossil on his way home. To his surprise, he has picked up a baby Kappa, a mythical water creature, who has been asleep underground for the past 300 years. Koichi names this baby creature “Coo” and brings him to live with his family, and soon the two are inseparable friends. However, trouble abounds as Coo struggles to adjust to life in suburban Tokyo, and begins to miss his family, leading Koichi and Coo to embark on a summer road trip adventure in search of other Kappa.
