One day he picks up what he thinks to be a fossil of an ancient creature but turns out to be a baby kappa (a mythical Japanese water creature) that was sleeping underground for the past 300 years, and he names it "Coo". K�ichi and Coo become good friends and the kappa starts living with the human boy's family. However, Coo cannot not fully adjust to life in present-day Higashikurume and starts to miss his own family.
