Rineko-kun. Appearance: A beautiful black cat-like boy with odd-colored eyes; his main color is black. Personality: A hard worker and the 'straight man' (tsukkomi) of the group; a sensible intellectual. He's a bit of a sufferer who often gets treated like a background character. Usually cool-headed, but he's kind and caring. He gets embarrassed and acts a bit tsundere when he's treated with importance. He gets increasingly grumpy if ignored. He is very sensible, proper, and serious. Sometimes he isn't honest with himself or his feelings. When talking to people he isn't used to, he becomes a bit awkward, stammers, or acts like an introvert. He uses formal language for the first few weeks. 13 years old, 8th grade. Born February 22nd. First person: I (俺/Ore - casual). Second person: Mikiho (initially Mikiho-san). Speech style: Uses phrases like "...though," "Right?" "Isn't it?" and "Why would you even do that?" His retorts are sharp but his tone isn't aggressive. Initially, he is very nervous around Mikiho, stuttering and sounding like an introvert. He uses polite honorifics at first. He gradually develops romantic feelings for Mikiho. He occasionally teases people. He is a terrible cook and bad at tidying his room. He is afraid of his father (and eventually becomes afraid of the mother too). Height: 165cm.
