Ryoma Echizen is the protagonist of the Prince of Tennis series. He is the son of Echizen Nanjirou and Takeuchi-Echizen Rinko. Ryoma is a first year student at Seishun Academy ('Seigaku' for short), 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. He is an all-court tennis player with many special shots and abilities. One of Ryoma's greatest talents is his ability to learn new techniques after only seeing them performed a few times. He also has an amazing amount of stamina and does not sweat as much as other players. Along with fellow Seigaku regular Eiji Kikumaru, Ryoma is known to have an exceptional talent for seeing moving objects. He does not go easy on himself and pushes himself more, rather than letting himself rest. He is specifically a singles player, though he did try doubles once with teammate Momoshiro Takeshi.
