Miru is a little sea otter like the ones found in the north of Japan. One day, Miru forgets to attach himself to the other otters with seaweed, as they usually do so as not to get separated while sleeping. As he sleeps, strong currents separate him from the other otters and bring him all the way up a river. When he wakes up, Miru finds himself in another world!
