In a world where messengers must safeguard their assigned gods with wings, Shin stands out with his small, nonfunctional ones, becoming a target of mockery. Despite his limitations, Shin seizes the opportunity to protect a peculiar deity residing on a nearby mountain. Initially, the task appears simple as the god appears as nothing more than an adorable, fluffy creature. However, a shadow looms over the mountain as other messengers vanish without a trace. Despite escalating suspicions, Shin remains steadfast in his belief in his gentle god, sensing an uncanny familiarity with the enigmatic being.
