Tennis no Oujisama: Atobe kara no Okurimono - Kimi ni Sasageru Tennis Prince Matsuri

Keigo Atobe uses the wealth and influence of Hyoutei Academy to organize an extravagant festival that gathers middle-school tennis teams from across the country. Games, attractions, competitions, and a fierce inter-school relay turn the day into a celebration every bit as excessive as its host.

Although Atobe presents the event with his usual confidence, the enormous effort hides a more personal motive. As Seigaku and their familiar rivals compete and enjoy the festivities, it gradually becomes clear that the entire celebration was created as a gift for someone important to him.
