Les MisÚrables: Shōjo Cosette is a 2007 anime. Produced under the World Masterpiece Theater banner, it is an adaptation of the novel Les MisÚrables. It ran for 52 episodes, airing weekly for the entire length of 2007.
This anime provides (in addition to those shared with the novel) examples of:
Adaptation Dye-Job: In the book, Marius has curly black hair and Cosette is brown-haired. In the anime, Marius has straight golden brown hair and Cosette has blonde hair.
Bishōnen: Marius, Enjolras, and other members of the ABC Friends.
Book Ends: The series begins with little Cosette and Fantine walking down the road. The series ends with Cosette and Marius walking down the same road with their own little girl.
Brick Joke: Marius getting Cosette's name wrong is brought up one last time at the barricade.
Central Theme: People can change. And if they can change, so can the world.
Compressed Adaptation: Even with 52 episodes to tell the story, this is still a children's adaptation and some parts are omitted because they're not appropriate - Fantine is never explicitly shown to be a prostitute, for example.
Doomed Moral Victor: Les Amis, of course. Gavroche and Marius are the only ones to survive: Gavroche because he was saved by Chou Chou before the soldiers could kill him, Marius because Valjean saved him.
Establishing Character Moment: We first meet Gavroche as a baby. Cut to three years later and we see him put a mouse in Eponine's hair, when she's bullying Cosette. This establishes him as the kind of kid who will stand up for those who can't do so for themselves, and Foreshadows his joining Les Amis later.
Foreshadowing: When Gavroche and Cosette, as children, are running over a hill together, Gavroche falls and lies facedown for a moment. Cosette, concerned, turns around and says his name. When she finds him after he was shot at the barricade, he is lying facedown on the pavement. She gasps and says his name over and over, nearly in tears.
Heel-Face Turn: Javert goes into one after seeing a sunrise and thinking about Valjean's words about how people can change, instead of committing suicide.
Lighter and Softer: It has more people survive than other adaptations and quite a few added cutesy scenes, especially involving Chou Chou the dog, a character whom Cosette and Gavroche adopt as a puppy. He ends up saving Gavroche from the barricade. However, just because the anime looks like this doesn't mean that the anime itself is bad or entirely light and cutesy. Indeed, one scene involves Cossete being beaten by Madame Thenardier with a broom while shielding Chou Chou with her body.
