Plot

Tragically orphaned by a car accident, the Kasugano twins travel to their grandparents' countryside residence in Okukozome via railcar, hoping to reconstruct the shards of a shattered life. Two lonely souls so physically alike, yet spiritually divergent, they are unaware of the challenges these conflicting expectations will unveil in the days to come. Uncertain of the future, Haruka Kasugano clings to memories of the past, hoping to find the strength he needs to protect his ailing sister. As the story develops, it tells four stories, each with one girl; Kazuha Migiwa: rich but kind, Akira Amatsume: polite but sad, Nao Yorihime: depressed but hopeful; Sora Kasugano: petite but fierce.

Adaptations

Anime

Yosuga no Sora was adapted into a 12-episode anime series that started airing on October 4, 2010. Each episode consists of a 22-minute feature segment and a 3-minute omake segment. The main plot of the anime is presented in a multi-arc branching format that independently tells the stories of Kazuha, Akira, Nao, and Sora while sharing certain common episodes. The title of each episode incorporates the names of the characters it concerns. The bonus segment focuses on Motoka's story, relying more extensively on humor and super deformed character designs. Each segment has its own ending credit sequence in each episode. The anime's opening theme is "Hiyoku no Hane"-(比翼の羽根) by eufonius, and the ending themes are "Tsunagukizuna"-(ツナグキズナ) by Nekocan feat. Junca Amaoto, and "Pinky Jones"-(ピンキー・ジョーンズ) by Momoiro Clover. The first volume of the series was released by King Records for DVD and Blu-ray Disc formats on December 22, 2010, and the final fourth volume was released on March 26, 2011, with a limited edition Blu-ray Disc, including the stuffed toy strap of Sora Kasugano. The series premiered on Toku in the United States on December 31, 2015.
