[Half-Broken Music Box]A doujin anime produced by ElectromagneticWave and directed by Keiichiro Kawaguchi. Released at Comiket 75.
Kowarekake no Orgel begins in medias res with a look at the two main characters, Keiichirō and Flower, sitting in a van in the rain. It then flashes back to the beginning, showing Keiichirō taking shelter from the rain near a trash heap next to which a small girl is sitting in a chair with a sunflower, unconscious. After second thoughts he decides to pick her up and takes her to a technical specialist. The scene reveals that the girl is an older model of a popular line of service androids, called Parents, who is broken. Because she is an older model, the specialist says she cannot be fixed, and provides Keiichirō with the necessary sticker to dispose of her. Keiichirō leaves her among some junk in his house before going to sleep, intending to throw her out the following day.
During the night, the girl begins functioning and finds herself in a strange house with no memory of the past. When Keiichirō comes downstairs the following morning, he finds her preparing breakfast. He names her Flower after the sunflower she was holding when he found her. It is revealed that evening, when Flower prepares the same meal for dinner as she had for breakfast, that Flower suffers from short-term memory loss, so Keiichirō buys her a diary which is used as the primary means of narration in the OVA. Over the next several weeks Keiichirō begins to teach her about the world, and more indirectly about himself and his troubled past.
