Children Who Chase Lost Voices

In the quiet mountain town of Mizonofuchi, eleven-year-old Asuna Watase lives a life shaped by loneliness, routine, and the soft static of her treasured crystal radio-her only link to a world beyond her own. But everything changes the day she encounters a mysterious, long-haired boy on a railway bridge, a boy who saves her life and then vanishes as suddenly as he appeared. His name is Shun, and he comes from a place Asuna has never heard of: Agartha-a legendary world hidden deep beneath the earth.

When Shun dies under mysterious circumstances, Asuna refuses to believe it. Her longing for answers pulls her into a dangerous journey with her stern new substitute teacher, Mr. Morisaki, a man driven by a desperate wish to resurrect someone he lost. Together, they enter the ancient underground realm of Agartha, a land filled with forgotten gods, crumbling civilizations, and creatures both wondrous and terrifying.

Asuna travels deeper into this breathtaking but perilous world, guided by fragments of Shun's past and shadowed by her own unspoken grief. Along the way, she discovers Shin-Shun's younger brother-whose coldness hides a sorrow as deep as her own. Their fates intertwine as they confront the secrets of Agartha, the true price of miracles, and the meaning of loss.

In this sweeping tale of courage and connection, Asuna must face the hardest question of all: How far will she go for someone she has already lost-and what will she discover about herself along the way?
