A collaboration with the popular circle "Cyclone" has been decided for the first live-action adaptation! The tennis club's ace, Kaori Kitamura, has been troubled by her recent absenteeism from practice. One day, she's instructed by the coach to check on Ami's well-being at her home. Her childhood friend, Masaya, has told her that Ami has been acting up lately, but Kaori, as the captain, believes that if she talks to her, Ami will return to the club. However, a wicked thought arises in Ami's mind: she wants to drag Kaori, who excels in the "upper world," down to her own "lower world." Using her own sex partner, she orchestrates an attack on Kaori, marking the beginning of the ace's downfall!
