The girl Yuraia was born on a mountainous island in the middle of the ocean. Many wild animals live in the dense forests here, but the most dangerous creatures are considered to be the mysterious beings called "ochi". Some believe that it is just a fairy tale for children, others believe that they are hostile creatures. One day, Yuraia finds a lost ochi cub in the forest and decides to return it to its parents. The girl will have to find a common language with this unusual forest inhabitant and prove to people that it is better to be friends with ochi than to fear them.
