The Sukaku (Zhu He) family is a distinguished line of shamans that protects mankind from divine beasts. Our protagonist, Mutsuki, (Wang Yue) bears a promising future while his sister Uzuki (Chu Yue) completely lacks the capability to use any spiritual techniques. "You are not a child of Sukaku if you are not a shaman." Bound by those antiquated customs, Uzuki is forbidden from leaving the house. As her older brother, Mutsuki is determined to free Uzuki from her confines.
