Plot

The Seishun Academy Middle School tennis regulars are invited on a cruise by Sakurafubuki Hikomaro to play a match with his own tennis team. Aboard the cruise ship, Ryoga Echizen introduces himself to the team as Ryoma's older brother. Ryoma reveals that Ryoga was adopted by Nanjiroh many years ago, when they lived in America, but mysteriously left home prior to Ryoma enrolling in Seigaku. That evening, after a banquet dinner, Takashi Kawamura, being a sushi chef, remarks that the food did not taste as expensive as it looked. In the bathroom, Sadaharu Inui discovers that the marble on the wall is fake when he tears off a piece of wallpaper. It becomes clear that something is not right. The next day, Sakurafubuki reveals to Tezuka and Oishi that they are actually part of an illegal gambling plot. If they purposely lose their matches the next day, Sakurafubuki will rake in a lot of money from people that have betted on Seigaku winning. But, should they choose not listen and win the matches, the team faces the grim possibility of losing their lives.
