Plot
During the second program, Saeko is teamed with four others for a team fight. When Ringo Tatara surrenders and makes Rin Kashii angry, Saeko calms her down, saying that she will win her fight and they will need just one more win.

She faces Madoka Kirisaki. At the start of the battle she uses a slingshot to shoot a marble at him. Madoka deflects it and then sees the marble turning big and crushing the ground, making him realize that if he attempted to catch it or dodge it, she would have enlarged it and hit him. Madoka then proceeds to deflect or cut Saeko's marbles. In a last attempt, she uses all of her marbles surrounding him and creating a single path. She then rolls a large marble in the path and hides behind it, as Madoka cuts the marble she jumps out and attempts to shoot at him at closer distance to not allow him time to counter, however, breaking a piece of his stick, Madoka creates a small knife which he throws and cuts the rubber on the slingshot. He reveals he anticipated this and asks her to surrender. Saeko thanks him, knowing that he is stronger than her, he would look down on her, but she knew he would ask her to surrender and not cut her down. A marble then rolls under Madoka's legs and enlarges, hitting him in the crotch and knocking him out with Saeko taking the victory.
