Ryoma is a first year student at Seishun Academy ('Seigaku'), which he attends immediately after his arrival in Japan after formerly residing in the United States. Although only a first year in middle school, Ryoma had already earned notoriety through winning four consecutive titles in the American Junior Tennis tournaments – all in a little over a year. Due to his nearly invincible tennis play, Ryoma has earned the label 'prodigy' by the age of twelve. His looks and confidence make him highly popular with ladies, although he seems not to notice, having his focus exclusively on tennis.
