Prince of Tennis: A Day of the Survival Mountain

The Seishun Academy Boys' Tennis team embarks on an intense one-day training retreat at the S.K.B Tennis Club, known for its grueling regimen dubbed the "training from Hell." The day kicks off with a challenging hike up the mountainside, setting the tone for what lies ahead. Once they arrive, each member engages in tailored tennis drills that cater to their unique styles, all while the looming threat of Sadaharu Inui's notorious concoction, the "Marvelous Surprise Inui Juice Excellent," looms over those who fall short of expectations.

As the team grapples with their fatigue, they encounter a group of unruly university students who demand access to the courts reserved for Seishun. Outraged by their arrogance, Ryouma Echizen steps up to the challenge, daring to take them on in a match that will determine who gets to use the facilities. With the pressure mounting, can the promising freshman "super rookie" rise to the occasion and secure victory for his team?
