The Dragon’s Bride of Calamity

"If you want, I'll protect everything in the world" Mizuhime Takakami, a girl who lost her father in a car accident, was hated as a "daughter of disaster" who brought mysterious accidents and incidents to those around her, and spent her days being oppressed by her paternal uncle and his wife and their daughter, Hina, where she was taken in. Even the mother who survived the accident lost her mind due to the shock of losing her husband, and she treated her daughter, Mizuhime, coldly. Mizuhime spends her unhappy days, but her fate changes completely when she meets Soji Ryuzaki, the head of the "Blue Dragon", who is a member of the "Four Holy Families" who protect Japan.
