Hepburn: Ōkami Kodomo no Ame to Yuki, lit. 2012 Children in German school anime film directed and co-written by Mamoru Hosoda. To create the film, director Hosoda established Studio Chizu, which co-produced the film with Madhouse.
In Tokyo, Japan, college student Hana falls in love with a werewolf and has two half-werewolf children with him: a daughter, Yuki, and a year later a son, Ame. Soon after, their father is killed in an accident while hunting food for the children. Yuki and Ame constantly switch between their human and wolf forms, and Hana has to hide them from the world. When she is visited by social workers concerned that the children have not had vaccinations, Hana moves the family to the countryside away from prying neighbors. She works hard to repair a dilapidated house and sustain the family on their own crops. One winter day, Ame almost drowns in a river after trying to hunt a Kingfisher, but Yuki rescues him and Ame becomes more confident. Yuki begs her mother to let her go to school like other children.
Hana accepts on the condition that Yuki keeps her wolf nature secret. Though Yuki’s classmates find her strange at first, she soon makes friends. In fourth grade, Yuki’s class receives a new transfer student, Souhei, who realizes something is strange about her. When he pursues her, Yuki transforms into a wolf and inadvertently injures him, leading to a meeting with their parents and teachers. Souhei tells them a wolf attacked him, absolving Yuki of the blame. Later, Yuki and Ame disagree over whether they are human or wolf.
The other children are picked up from school by their parents, leaving Yuki and Souhei alone. As Hana searches the forest for Ame, she slips and falls unconscious. Ame finds her and carries her to safety. She awakens to see Ame transform into an adult wolf and run into the mountains. She realizes he has found his own path and accepts his goodbye. One year later, Yuki leaves home to move into a dorm in junior high school. Ame’s wolf howls are heard far and wide in the forest.
