She is sincere, polite, responsible, and values honesty, often taking problems seriously even when others are more carefree.

Miku is fascinated by Japanese history, particularly famous generals from the Sengoku period, and spends much of her free time reading about historical figures or collecting knowledge about them. She is shy, gentle, and introverted, often struggling to express her emotions directly or believe in herself. Despite lacking confidence, she quietly works to improve through studying, baking, cooking, and practicing social interactions. Her persistence, kindness, and willingness to face her insecurities gradually allow her to grow into someone far more confident than she once believed possible. 5’2
