A hard working sprinter of the track team who is on an athletic scholarship. Even though he is a talented sprinter, he is not as fast as Yamato in the 100 meters. He dislikes Yamato because he outperforms him in track and Honoka, the girl he likes, at the time only had eyes for Yamato. Like Yamato, he was scouted by the universities in his senior year at high school. When Yamato and Suzuka told the high school track club that they dropped out of Seijo University, he was the only member that was upset about their decision; there is also a running joke that in every picture he is in, he is cut off or just barely seen. Arima and Kenji represent Japan in the 100m and 200m.

Yamato transfers to Aoba High and is quickly smitten with Suzuka, the school’s rising star of track and field. Unfortunately, she’s totally uninspired by Yamato’s irresponsible nature. When the young man decides to step it up and join the track team, even his best efforts might not measure up to Suzuka’s standards. Will he go the distance for love or will Suzuka have him running in circles?

Yamato is ready for a fresh start. So when his aunt invites him to stay rent-free in her big-city boarding house in hustling, bustling Tokyo, Yamato jumps at the chance. There&rsquo;s just one teensy-weensy catch: It&rsquo;s an all-girl housing complex and spa! Things get even more nerve-racking when Yamato meets his neighbor Suzuka, a beautiful track-and-field star. She&rsquo;s not just the cutest girl Yamato&rsquo;s ever met, she&rsquo;s also the coolest, the smartest, and the most intimidating. Can an ordinary guy like Yamato ever hope to win over a girl like Suzuka?
