OVA series: The Nationals Arc
Seigaku wins the match with Shintenhouji and moves on to the finals. Meanwhile, Rikkaidai's Akaya Kirihara transforms into a demon as they turn around from there to win and face Seigaku in the finals--it is revealed by Rikkaidai's members that they lost the first two matches on purpose to prove Akaya's true potential. Kintarō, unwilling to wait one year to be able to challenge Ryoma again--or Koshimae, as Kintarō calls him--asks Ryoma for a one-point match. In the end the ball splits into half, each half on one side of the court, turning the over-40 minutes match into a draw..
Seigaku gana la eliminatoria contra Shintenhouji y pasa a la final. Kintarō, que no está dispuesto a esperar un año para poder volver a desafiar a Ryoma --o Koshimae, como le llama Kintarō-- le pide un partido a un punto. Mientras tanto, Akaya Kirihara, de Rikkaidai, se transforma en un demonio para dar la vuelta a la eliminatoria y enfrentarse a Seigaku en la final.
