Lia, the five-year-old daughter of the Duke, has recently become quite strange. She no longer likes candy; instead, she has a passion for swords. She refuses to obediently call her father, yet she always gazes at him with a fierce stare. In fact, on several occasions, she has even rushed into the conference room wielding a fruit knife, attempting to assassinate the Duke. Everyone assumed that the young lady had simply grown more irritable. Only the elf physician knew that within her body dwelled Moira—a vicious dragon who had just been killed by the Duke! Yet, despite her notorious reputation, this dragon not only avoids even the slightest touch of her enemy, but has also gradually come to be moved by her father's affection and her brother's protection. When will she finally achieve her revenge? Or perhaps, she can no longer bear to leave this family home?
