Miu Asakura's father stands as a central figure in her childhood trauma. He engaged in constant arguments with his wife, fostering a hostile home environment dominated by familial conflict. These disputes consistently led both parents to emotionally burden Miu with their sorrows and frustrations.

His eventual departure from the household left Miu solely in the care of her embittered mother, intensifying her sense of abandonment. This absence directly fueled Miu's reliance on fantasy stories as an escape from her harsh reality, cementing her tendency to fabricate tales as a coping mechanism. The resulting familial instability and his role in perpetuating domestic strife form the foundation of Miu's subsequent psychological struggles, including her social isolation and self-destructive behaviors later in life.
