One day, twin sisters Ikki, Uzzu and Emme, walking in the forest, find themselves in a magical land. They will soon learn that they can return home only if they help the inhabitants of Fairyland break the spell of the Four Mountain Giants. To do this, they will have to go down into the dungeons of the Four Mountains, find magic boxes and save the Seasons. On their way they will meet a variety of fairy-tale creatures: Yaga on a mortar, the Serpent Gorynych (and more than one!), the Whale Fish, talking cabinets and animals. Some will help the girls, and some will hinder them. The adventures will be both fun and sometimes scary, but definitely interesting and unusual!
