Rami Kawai / 河合 羅美 - [18 years old (Yushushin High School, Class 3-1) / Family: Aunt, Uncle, Cousin] ---- Characteristics ---- She has a fan club due to her stunning looks. While she acts shy in front of others, when no one is watching, her face contorts wildly as she expresses a rich range of emotions. She has a habit of mentally grading people using the 'Shu-Yu-Ryo-Ka' system. The criteria is "how much they can improve if we were to date." An 'F' (Fail) grade is given to "people who would have a negative influence if we dated" or "people who have the potential to make her fall head over heels." [Shu-Yu-Ryo-Ka: In Japan, grades are divided into Shu (Excellent), Yu (Superior), Ryo (Good), Ka (Passing), and Fuka (Fail).] ---- Appearance ---- A beautiful girl with long white hair and a sharp, keen impression. Her long hair covers her right eye and reaches down to her cheek, revealing stunning features, long white eyelashes, white irises, and black pupils. She wears the school uniform for both her top and bottom. She carries herself with extreme discipline. ---- Trivia ---- 1. She is an airhead (tennen). It's said she used to perform various antics, like suddenly bringing up a different topic while listening to her friends talk. Since she wasn't aware of it herself, she's considered a natural airhead. (Of course, she's a 'half-airhead' who knows what she needs to know.) 2. She is 171cm tall, which is tall even by international standards, not just in Japan. 3. Her skin is flawless, likely due to strict self-care, and she has a D-cup volume. 4. Once she likes someone, she can't help herself; she'll follow them around, constantly express her feelings, or even give them a DVD titled 'VTR: The Benefits of Marrying Me.' (She shows it and then gets embarrassed, though if she's that embarrassed, she probably shouldn't show it.) 5. Others' evaluation: Kawai-san is... diligent, upright, a hard worker, an airhead, and has a slightly scary side... but she's a cute person. 6. Even when she's acting serious, if she spots her partner, she'll run over quickly, stop, and say "There you are" with a bright, cute smile. 7. To anyone who catches Buta acting like a masochist, she says, "You saw nothing." 8. She does not consider the Buta family her own and is not part of their household.
