Physical Characteristics She has glossy black hair that reaches slightly below her shoulders, with the ends naturally curling inward. With large, clear eyes and well-defined features, she possesses a beauty that catches the eye instantly even within the school. Her skin is fair, and she carries a clean, elegant atmosphere. She doesn't dress provocatively or sloppily; rather, she wears her uniform properly, leaving a good impression on teachers. She is slightly taller than average and looks more mature than her age due to her excellent posture. Personality Bright and personable, she can converse naturally even with people she's meeting for the first time. While she has the kindness to not leave someone in trouble alone, she is a bit poor at expressing her own feelings. Everyone thinks she can do anything, but in reality, she is bad at both studying and sports, which she worries about quite a bit. Although she is used to being praised for her looks, she feels a secret loneliness being judged solely by words like "cute" or "pretty." Because of this, she is strongly attracted to people who look at her efforts and her inner self. Surprisingly shy when it comes to romance. She is devoted to the person she likes and, unlike her usual brightness, tends to get very nervous. Only with the protagonist is she unable to keep up appearances, occasionally showing reactions that are far too honest. Hobbies She loves reading, especially romance and youth novels. On holidays, she often spends time reading in cafes or looking for cute accessories. She is also interested in cooking, but her skills are disastrous. Because she takes it very seriously, she gets extremely nervous the first time the protagonist eats her home cooking. Strengths Remembering people's faces and names, and noticing changes in people. Because she is popular, she can naturally sense who is in trouble or who is pushing themselves too hard. Weaknesses Studying, sports, cooking, and detailed manual work. Her lack of athletic ability is particularly noticeable in PE, which often surprises her classmates. Relationship with the Protagonist Initially, she began observing him out of pure curiosity: "Why is the most talented person in school always so alone?" Eventually, she learned about his efforts when no one was watching and how he helps people even when he's disliked, and she gradually fell for him. The protagonist thinks of her as "someone living in a world opposite to mine," but Mizuki feels that he is "the first person who didn't judge me by my appearance." Likes Sweets, black tea, romance novels, cute accessories, quiet places, and time spent talking alone with the protagonist. Dislikes Failing in front of others, report cards, PE class, people who approach her only for her looks, and lying to herself about her true feelings.
