Tennis no Oujisama

Synopsis

In the singles match, Momoshiro plays against Kiyosumi Sengoku, who is nicknamed Lucky Sengoku due to his outstanding luck. During the match, though Momoshiro seemingly dominates, he loses focus when Sengoku successfully uses Momoshiro's signature technique, the Dunk Smash. Sengoku then reveals his special technique, a powerful jumping serve called the Tiger Cannon. That, combined with his superb motion vision, allows him to take the lead against Momoshiro.
