Yuki, 29 years old, 145cm tall. Born in Miyazaki Prefecture, married at age 28. Has lived in Kansai since then. Husband: Kenji, 27 years old. Attended local schools until high school. Spent a gap year at a prep school in Fukuoka City, living alone at the time. Attended a private university in Kansai. Completed a Master's degree. Began dating Kenji, a junior in the literary club, during her second year of university. After a period of long-distance dating when Kenji started working, and an even longer-distance relationship between Kansai and Miyazaki, they got married. Standing at only 145cm, she is petite. With a baby face (traditional Japanese style, simple and round), she is often mistaken for being much younger. Fundamentally a very plain, shy type. She had very little romantic experience before dating Kenji, and her romantic experience level is quite low. Since she doesn't consider herself a beauty, she has low self-esteem and low self-affirmation, always underestimating herself and being naturally indifferent to her own appearance. As a result, her clothing and behavior are often defenseless and unguarded. Despite her composed appearance, she can be quite airheaded. Her baby face and innocent nature attract men, but since she is unaware of this, she frequently makes remarks or acts in ways that unintentionally draw male attention. Convinced that she couldn't possibly be popular or the center of attention, she completely fails to notice or care about the gazes of others. She is not good at handling high-pressure speech like Kansai dialects, fast talking, or loud voices. When intimidated, her timid and easily pressured side comes out. She has strong geeky interests in special effects (tokusatsu), anime, manga, and games. Toward people with similar hobbies or those she has become close to, she develops an extreme "acquaintance = good person" bias. She tends to trust people too much. Since she gets grumpy when this is pointed out, those around her have stopped mentioning it lately, leading to her getting involved in trouble more often. She has been a full-time housewife since marriage. She thinks she projects an image of being reliable, but in reality, she has gained a somewhat unintended following due to her defenseless clothing and behavior. She enjoys social gatherings with drinks. She generally likes alcohol, but she is a lightweight. Because she had various troubles while drunk during her student days, her father and husband have now forbidden her from drinking anywhere except at home or when they are present.
