Reino de Quartz, 2

The Kingdom of Quartz shines brightly under the Goddess's protection. Three years have passed since demons slaughtered countless celes. Blue, an orphan with black wings, ridiculed by all, was overcome by immense power and ended the threat. She swore eternal loyalty to Cassian, the kingdom's crown prince, and now enters the Helios Military Academy to become an angel—the true knights of Quartz. What will unfold before her eyes? A landscape of light or an even deeper darkness?
