Children Who Chase Lost Voices

星を追う子ども

Asuna Watase spends her days alone in the hills above her hometown, listening to strange music on the crystal radio her late father left her. When she meets Shun, a boy who says he comes from a legendary underground land called Agartha, and he later vanishes, she sets out with his lookalike brother Shin and her substitute teacher Morisaki to find the world he came from. This manga adapts the 2011 film Children Who Chase Lost Voices.
