Children Who Chase Lost Voices From Deep Below 追逐繁星的孩子 (2011) (Blu Ray) (Normal Edition) (English Subtitled) (Hong Kong Version)

Asuna is a young girl who has been forced to grow up quickly due to the death of her father, while her mother, a nurse, works long shifts at a hospital. Asuna spends her solitary days listening to the mysterious music emanating from the cat's-whisker receiver her father gave to her as a memento, accompanied by Mimi, her little cat with strange red markings.

One day, while walking to her clubhouse across a bridge, she is attacked by a fearsome creature and saved by a mysterious boy who calls himself Shun. Asuna treats Shun's wound from fighting the creature and later they both listen to Asuna's radio. Shun tells Asuna he is from another country called Agartha and that he came to this place to find something. He then gives Asuna a blessing in the form of a kiss to the forehead. Asuna leaves hurriedly and tells Shun she'll be back tomorrow. Shun, now alone, looks up at the stars and falls from the ledge to his death.

The next morning, Asuna hears from her mother that a boy was found dead in the river, but refuses to believe it's Shun. In school, Mr. Morisaki, a substitute teacher, is giving a lecture on a book which grabs Asuna's attention when he mentions Agartha, the land of the dead. After school, she visits Morisaki and asks him about Agartha. Morisaki explains that long ago when humankind was young, it needed the guidance of Quetzalcoatls, keepers of the dead, until humans matured and no longer needed them. They went underground along with a few humans who joined them.
