The series' main character who ends up living with her ex-boyfriend Mizuto after their parents get married. She's a bookworm with a real passion for mystery novels—the kind of person who'd rather curl up with a good story than do pretty much anything else. What's interesting about her is the transformation she went through. She used to be pretty withdrawn and shy, but somewhere along the way she made a conscious effort to break out of her shell once she got to high school. It worked out—she's become popular and social, even though that quieter, more introverted side is still part of who she is.
