The Seishun Academy Boys' Tennis team embarked on a one-day boot camp at the S.K.B Tennis Club. Their endurance was tested as they ran all the way up to the mountainside club for the infamous "training from Hell." Following the challenging run, they partook in specialized tennis practice tailored to their playstyles. The boys were motivated to complete their daily tasks, as they were threatened with Sadaharu Inui's new concoction, the "Marvelous Surprise Inui Juice Excellent." In addition, a group of impolite university students also arrived at the resort and demanded to use the courts initially reserved for Seishun. The team was irritated by their arrogance, and Ryouma Echizen singlehandedly challenged them to a match. The victor would claim the right to the courts. Can the talented freshman, known as the "super rookie," defeat the pompous team alone?
