On the floating island of Celestia, where white towers pierce the heavens and divine waterfalls spill into endless clouds, stands Angel Academy—the most prestigious school of magic in the world. It is a place for the gifted, the blessed, and the bloodlines destined for greatness. Born with grey hair and grey eyes that unsettle even the boldest gazes, Haru carries a truth he can never reveal—he is neither wholly angel nor wholly demon, but both. A contradiction in flesh, a sin that should not exist. To survive, he must blend in, endure the whispers, and pretend to be ordinary. Yet Angel Academy is no sanctuary. Rivalries ignite, trials push students to their limits, and a council of elites rules the halls with power and pride. Haru’s very presence threatens the balance of the school—and perhaps the world itself. When the first cracks appear in Celestia’s shining facade, Haru finds himself caught between light and darkness, hunted and feared, yet destined to stand at the center of it all.
