Yuu Hiyama

Yuu Hiyama is an ordinary middle school girl whose life was shattered when a supernatural creature known as 'Fushuma' caused the plane crash that claimed her father's life. Consumed by grief, she initially directed her anger toward her father's colleague Atsuzawa, believing him to be responsible. It was only through joining forces with Aozuki Ushio that she uncovered the true culprit and finally released the years of misplaced resentment she had carried. Emerging from this ordeal, Yuu rediscovered her inner strength and developed a deep empathy for those around her. In the later chapters of the story, she becomes a vital civilian ally to Ushio, standing as living proof that courage and kindness can flourish even in the wake of tragedy.
