Child of Kamiari Month

One summer vacation, Ruka meets two boys, "Umi" and "Sora," whose upbringing contains strange and wonderful secrets. Drawn to their beautiful swimming, almost more like flying, Ruka and the adults who know them are intertwined in a complex mesh... Meanwhile, an unexplained anomaly is occurring all over the world: fish are disappearing. Thus begins a marine adventure of boys and girls to captivate all the senses!

Yearning to get along with others and not be disliked, first-year high school student Hiiragi finds himself unable to say no whenever someone requests something of him. One summer day, while unsuccessfully carrying out yet another request, he encounters an oni girl named Tsumugi, who has come to the human world to search for her mother. She does whatever she pleases and is the complete opposite of Hiiragi. Snow mysteriously begins to fall... and their adventure begins.

The theme of the film is the love between parents and children. The story covers 13 years and begins with a 19-year-old college student named Hana who encounters and falls in "fairy tale-like" love with a "wolf man." After marrying the wolf man, Hana gives birth and raises two wolf children—an older sister named Yuki who was born on a snowy day, and a younger brother named Ame who was born on a rainy day. The four quietly lived in a corner of a city to conceal the existence of the "wolf children," but when the wolf man suddenly dies, Hana decides to move to a rural town far removed from the city.

The world is ruled by a diversity of inhuman beings, who persecuted humans and drove them to near-extinction. One day, the forest guardian Golem meets a human girl. This is a chronicle of a journey that would bind a member of the dying "human" clan to the forest guardian Golem, as father and daughter. The first episode received an advance web distribution on January 3. The regular TV broadcast started on January 10.
