In the bustling city of Ashen, where humans and demons coexisted in an uneasy harmony, a young boy named Kaito lived a life of solitude. His piercing blue eyes and raven-black hair made him an outcast among his peers. The city's inhabitants whispered about his mixed heritage, how his mother, a human, had fallen in love with a powerful demon. The rumors only served to fuel Kaito's feelings of isolation.
Kaito's mother, Emiko, had been a kind and gentle soul. She had met Kaito's demon father, Ryujin, while working as a healer in the city's infirmary. Despite the danger and societal taboo, the two had fallen deeply in love. They had built a life together, one filled with laughter and joy. But fate had other plans.
