Mamori tries to help Sena, and Sena can't find enough time to change into Eyeshield 21! So after school, he practices by himself by the riverside. After catching a cold because of training in the rain, Sena is forced to stay home during the Ojou vs. Gunmen game. Deciding to go, he manages to get there about halfway through the game, when Riku and Shin are in a showdown, but problems start when Mamori spots him and urges him to go home. Then, shy Sena says the words that Mamori was sure she would never hear: "Leave me alone! I want to be here right now!"
