After being unfairly fired, Reito Naoi spirals into desperation and makes a mistake that lands him in jail.
His life changes when a mysterious lawyer offers him a deal: follow her instructions, and he’ll be released. That instruction comes from Chifune Yanagisawa, his late mother’s half-sister, who commands him to become the Guardian of the Camphor Tree at Tsukigo Shrine.
Confused but compelled, Reito takes on the role and meets people whose lives are tied to the tree: a devoted father, his suspicious daughter, and a young man torn over family obligations.
Through these encounters, Reito’s once-colorless world begins to gain meaning—and the mystery of the camphor tree slowly draws him toward an unexpected truth.
