Winner of the 19th Shosetsu Subaru Newcomer Award. The novel centers on Yukihiko, a middle school boy who can no longer play basketball after being pushed off a cliff by a friend, and follows the arrival of a strange science-minded boy, an occult-leaning girl, and the sense of unseen beings as the world around him slowly changes. It is a large-scale coming-of-age novel where ordinary wounds and uncanny events overlap.

Amid confusion and sorrow, the world is gradually wrapped in a strange kind of tenderness.
