The forces of darkness are stirring once more, and the Quark Clan faces an unprecedented crisis. The Saint Ya Princess from the prophecy has arrived, destined to be the Nayia Princess’s counterpart in light and shadow, bound to live or die alongside her. The new student Shirley Si Sheng Ya transfers to the Meng Academy, bringing a Holy Light Scroll Messenger capable of purifying darkness. Her power is a source of hope, yet it could also be the spark that sets the Nayia Princess’s fate in motion.

When she and her younger sister Wu La La pass each other in the corridor without recognizing one another, the wheels of fate begin to spin wildly. This time, the sisters and the newly arrived Saint Ya Princess must face an ultimate trial that transcends life and death and tests their trust in one another. As the boundary between light and shadow begins to blur, can they rewrite the tragic fate of ancient times?
