A boy finds an orphaned deer with a golden tail and decides its life matters more than his own loneliness. The hunters come anyway. What starts as a simple rescue becomes a quiet stand against a world that destroys beautiful things without asking why, and Kanta learns that protecting something you love means standing alone when everyone else walks past. By the end, you understand why a single golden tail can break a child's heart.
Kanta finds himself raising an orphaned sika deer he names Poyu, forming an unlikely bond that fills the emptiness in both their lives. What makes Poyu different from other deer is striking: a shimmering golden tail that catches light and attention alike. When word spreads of this rare animal, hunters begin closing in, forcing Kanta to confront a harsh reality about human greed and nature's vulnerability. He becomes determined to shield Poyu and the other deer from those who would exploit them for profit or sport. The story weaves together a child's pure desire to protect what he loves with a darker history of how humans have hunted sika deer to near extinction. Kanta's journey transforms from simple pet ownership into something weightier: a stand against indifference and destruction. The tone balances genuine warmth between boy and animal with growing tragedy as external forces threaten everything. This is fundamentally about what we sacrifice when we refuse to value life beyond our own needs, told through a relationship that asks whether one child's love can matter against the world's carelessness.
