新テニスの王子様 氷帝vs立海 Game of Future

Keigo Atobe takes Hyotei Academy's middle school side onto the court against Seiichi Yukimura's Rikkai, a match the manga never staged. It is set after the U-17 World Cup, with both schools' regulars filling out the singles and doubles slots and old national-tournament results hanging over the draw. These two ONA episodes were written as an original story for the anime rather than adapted from a published arc.
