In the bustling city of Aegis, where magic and science coexist, three races-humans, demons, and mysterious beasts-live alongside the unique semis. In this world, individuals possess either mana or aura hearts, rare and powerful gifts. Oliver, a storyteller with light green hair, weaves tales of unity and discord, of kingdoms' rise and fall. Unbeknownst to all, Oliver carries a secret power that could change the world. As the children gather to listen, they don't yet realize how these stories will entwine with their own destinies, and whether Oliver's hidden abilities will lead him to become a hero of unity or a villain of chaos in the heart of Aegis, a place where magic, diversity, and a forgotten past hold the key to an uncertain future
