In a world divided by races, humanity once stood at the pinnacle, blessed with unmatched power. But power breeds fear, and fear breeds hatred. A mysterious group known only as the "Unknown??" launched a merciless campaign called the Annihilation, reducing entire human kingdoms to ash. At the heart of one such massacre stood five-year-old Nao, who lost her home, her friends, and her family in a single night. Saved in her final moments of despair by a loyal guardian, she was raised in the ruins of that world haunted by grief, rage, and an unquenchable need for answers. Now a young warrior with terrifying potential, Nao steps into a fractured world ruled by suspicion and buried secrets. Along her journey east, she will train, forge fragile bonds, endure betrayal, and uncover truths that threaten to shatter everything she believes. But the deeper she searches, the more she questions whether the answers will heal her… or destroy her. Why did they seek humanity's total destruction?
