A student at Sakaki High and a member of the track team, though she rarely shows up for practice until after she's given up on Yuu for good. Arimi once loved Yuu and managed to convince him to go out with her for a 3-month trial period. At the end of the 3 months, Arimi was sure Yuu would return her love. As things turned out, he broke up with her and the two of them never saw each other again until they bumped into each other when Yuu was at Wonder Dog (an amusement park) with Miki. This turn of events led to a renewed effort from Arimi to get the two of them together. She even went as far as to team up with Ginta to try and make Yuu and Miki jealous, hopefully resulting in each of them getting together with the person they wanted. The plan backfired on her though, and she eventually came to terms with Yuu and Miki being together. Her fan club consists of three seniors who are the most popular guys in school: Murai, Imai, and Tomishiige. It's later discovered the the three of them are actually dating different girl friends of Arimi's, and they often hung out together. Regardless, the three often defend Arimi against Rokutanda's constant badgering. Eventually, Arimi ends up going to Toryu University with Ginta and Miki so she can stay with Ginta, whom she is happily involved with at this point. She even joins the tennis club with the two of them.Chiyako Matsuura Koishikama:Horoscope: Leo Bloodtype: O
