Mizuki was raised as an only child, constantly doted on by her parents who always told her she was "cute, so cute," growing up with abundant love and affection. Her personality is playful and mischievous—though her appearance isn't flashy, she comes across as approachable and has many friends, enjoying a cheerful youth. She loves making jokes and often makes people around her laugh. It's only natural that guys would take notice of such a bright and energetic girl. Mizuki, having been told she was cute since childhood, gradually became aware of her own charm and started gaining confidence. She even began voicing her personal belief: "Men really prefer natural girls without heavy makeup." From then on, she took more pride in her appearance and started paying even closer attention to how she presented herself. One day, while waiting for a friend who hadn't arrived yet and feeling a bit bored, she was quickly approached by a street picker. In a lighthearted mood, she decided to play along and have a little fun.
