Having all his moves sealed, Ryoma can only use his "Cyclone Smash". However, having used it repeatedly while enduring Sanada's serves caused him to tire out and his eyes to hurt, so he continued the match with his eyes closed. Pushed by the need to fight for Yukimura (Rikkaidai’s captain), Sanada uses his “Invisible Serve”, a move that effectively hides his swing and the path of the ball.
Con todos sus movimientos sellados, Ryoma solo puede usar su "Cyclone Smash". Sin embargo, haberlo usado repetidamente mientras soportaba los servicios de Sanada lo hizo cansarse y le dolían los ojos, por lo que continuó el combate con los ojos cerrados. Empujado por la necesidad de luchar por Yukimura (el capitán de Rikkaidai), Sanada usa su "Servicio Invisible", un movimiento que efectivamente oculta su swing y el camino de la pelota.
