You might think this sounds like a fairy tale. You might even laugh at my story. You probably think that stuff like this just doesn’t happen. But everything I tell you is true. This is the story about my mother, and the wolf man she fell in love with.
Wolf Children Ame and Yuki is a 2012 anime Slice of Life film by Mamoru Hosoda — director of Digimon: Our War Game, The Girl Who Leapt Through Time and Summer Wars — about a young woman named Hana who falls in love with her mysterious college classmate who is actually a wolf man. The couple produce two children who also possess their father's lineage; the big sister Yuki, who was born on a snowy day, and the little brother, Ame, who was born on a rainy day.The wolf man suddenly dies one day, leaving Hana to raise the two wolf children herself and struggle to keep their secret. But when the family is threatened by eviction, child services, and neighbors annoyed by Ame's constant crying (and often both Wolf Children's howling, which the landlady mistakes for pets), Hana decides to move out to the secluded country side where her kids can roam free.
This film provides examples of:
Absurdly Youthful Mother: Hana, so young-looking and cute that she can easily be mistaken for Yuki and Ame's big-sister. This is perhaps somewhat justified in that she probably had Yuki within her first year or so of college, meaning she was already pretty young
Adaptation Expansion: A downplayed example: the English dub explains the wolfman's life before he met Hana in more detail near the beginning of the movie than the original Japanese Dub did. However we don't learn much more. Despite that it's still a nice little bonus as it builds his character some more.
While the manga adaptation compresses a lot of the story for sake of flow of plot, it makes up for it by having a few tidbits of bonus story, such as a small comic where Yuki catches a cold, and an epilogue that gives us a glimpse at Yuki's life at her new school, while she writes a letter to her mom. It also gives a possibly slightly happier ending than the film, implying that Ame still visits Hana occasionally after he chooses to live as a wolf; she finds a peach left by the door, similar to how she took a peach to give to Sensei when Ame took her to meet him.
Adult Fear: Ame nearly drowns after falling into a river while trying to catch a bird. Having lost her lover in a similar scenario, Hana is understandably scared out of her wits when Yuki pulls Ame out and he isn't breathing. Thankfully, Ame lives.
Deconstruction: The idea of raising werewolf children is played fairly realistically, with incidents like child services banging down Hana's door asking why the kids have no immunization records (presumably, Hana simply didn't want to deal with a potential wolf-shift at the doctor's office) and Hana being unsure whether to take Yuki to a vet or a doctor after she ingests silica gel.
Dedication: The dub's production is dedicated to Nirasaki's actor Jerry Russell, who died a few months before the movie was released in America.
Determined Widow: While they were never married, Hana certainly fits the trope in terms of her devotion to her dead lover and their children.
Expy: It's likely coincidental, but Ame's personality and Character Development is very similar to Bambi; a gentle, shy kid growing up to become aloof and stoic like his father, to the point he distances himself from his family. Ame's final appearance is even similar to Bambi's; standing at the top of a cliff while showing off how magnificent he's become.
Ghibli Hills: Hana's new place in the country. It's a beautiful, verdant locale (in the warm seasons, at least) with dense forests and plenty of semi-magical wildlife. This is shown in full effect in a montage where Ame and Sensei the fox go exploring in the mountains.
Girliness Upgrade: As she ages, Yuki dresses more fashionably and makes it a point to try and fit in with the other girls more.
Irony: As toddlers, Yuki embraces her wolf side and often transforms while Ame prefers his human form more and even states that he hates his wolf heritage at one point. Towards the end of the movie, Yuki prefers being human while Ame abandons his human side altogether and decides to live as a wolf in the wild.
Ame and Yuki however end up being more like their parents then they realize by the end. Ame takes a grown up, mature lifestyle despite being young much like Hana did, and Yuki choses to live as a human who still has her wolf side and reveals it to someone important to her, just like her dad.
Last of His Kind: The wolf man is the last surviving descendant of the Japanese wolf, a subspecies of the gray wolf which in real life has been extinct since the early 20th century. When he dies, Yuki and Ame become the last of their kind.
Limited Wardrobe: While less extreme than most examples of this trope, throughout most of the movie Yuki wears a pink one piece dress and then switches to a blue dress over a white blouse while Ame wears the same clothes as his father did.
Magic Pants: Happens at certain times, but noticeably averted in others. At least one scene shows Hana picking up her children's clothes to give them back later.
Mama Bear: Hana is insanely devoted to her children and will do anything to keep them safe. Without the wolf man, Hana is left to raise her two children alone, but she never complains and she never shows any resentment towards her kids. She leaves her comfortable life in the city behind to find a safe place to raise her kids, working her ass off to restore an abandoned old house in the country. Even though she has no idea how to raise half-wolf children, she tries her best to support them. When Ame leaves for the mountain during a typhoon, Hana follows him in only a rain-jacket and rain-boots. The terrain is steep and treacherous on the mountain, moreso when it's pouring rain and gusting wind, but Hana keeps going in order to find her son and keep him safe.
This is referenced when she runs into a literal mama bear and her two cubs while searching for Ame in the forest.
Meaningful Name: Yuki was born on a snowy day; Ame was born on a rainy day.
Ame abandons his humanity and lives as a wolf in the forest on a rainy day.
My Instincts Are Showing: Something Yuki and Ame struggle with throughout the film - especially as toddlers, when their puppy like behavior can't easily be reigned in. Ame gives in entirely and opts to abandon his human side.
Nightmare Fetishist: Before her Girliness Upgrade, Yuki would do things like play with snakes and collect animal bones. The fact that these hobbies send the other girls running away screaming leads to her abandoning these habits.
Fridge Brilliance: Given that the story is told by Yuki, who hardly got to see her father, the lack of a name is based off what she knows or was told. Since Hana refers to him as "Your Father", thats just his name to her.
Earlier Yuki when she slashes Sohei's ear because he won't leave her alone.
Red Oni, Blue Oni: Yuki's red to Ame's blue. Interestingly, this dynamic is reversed by the end of the movie.
Show, Don't Tell: The montage with Hana and the wolfman living together, Hana finding out she's pregnant and their busy, sometimes struggling, but also heartwarming everyday lives up until Yuki is born is accompanied by a gorgeous piano piece and practically no dialogue.
