Eventually, she was so cherished by the King that he bestowed upon her the "Flame Butterfly," which sends anything it touches to the underworld. Yet, whenever she returned to the living world, she was exploited by the main family for her good fortune. Even when forced to live in a closet and subjected to abuse, the ever-optimistic Yafu used her butterfly to burn nothing but sweet potatoes and steamed buns. Then one day, Haruomi, the head of the main family who was supposed to have died in battle, returns. Though Haruomi is severely injured and wrapped in bandages from head to toe, his charismatic presence as the head of the family remains intact.
