Emerson, Arima

エメルソン・有馬

He held the national top ranking in the 100-meter sprint and attended Toudo University High School. During middle school, he was consistently defeated by Kazuki, a matter that remains sensitive for him. He has a group of fans who follow him to tournaments. Like Suzuka, he accepted the offer to study abroad in the United States, keeping track of Yamato's running times in Japan while away. Later, he chose to attend Touto University and join their track team. Tetsuhiko and Souichi used him in an attempt to reignite Yamato's competitiveness. When this yielded no reaction, he asked Yamato what was wrong during their walk home. After Yamato explained, he replied that, if it were him, he would have the girl get an abortion because track is the most important thing to him. This remark sparked a fight, as Suzuka is the most important person to Yamato. Near the end of the series, he tells Yamato through Kenji that he better see him at the Olympics. Arima and Kenji represent Japan in the 100m and 200m.
