A Song of Birds Singing in the Empty Mountain, I Signed an S-Level Player Contract

Lin Ziye travels through a crisis world where void monsters invade and music has just been enlightened. Those who compose and perform moving music can be blessed by the power of music and become musicians admired by thousands of people. There are also human women who have awakened as "players". They can contract with musicians and use their musical power to transform into Valkyries and fight against void monsters. Lin Ziye: "I only contract with S-level performers."
