Haru's life changes forever on a quiet midnight when he wakes to the sound of eerie laughter and discovers terrifying spirits outside his window. Just when fear overwhelms him, the spirit of his late grandmother appears and reveals a shocking truth: she was murdered by someone she trusted. Before disappearing, she gives Haru one mission—to find the legendary Demon Sword, the only weapon capable of defeating the powerful spirits that threaten the world. As Haru begins searching for the truth, he notices something even more frightening. His parents are no longer acting like themselves, and the people around him seem strangely different. With dangerous spirits watching his every move, Haru must uncover the mystery behind his grandmother's death before the darkness consumes everyone he loves. Some secrets should never be awakened... but Haru has already seen them.
