While setting off for a training camp, the girls come across Kumami Tsukinowa, a former teammate who appears to have a history with Agari. As the camp gets underway, Agari, who is worried about her skills after narrowly beating Zakuro, struggles with hitting lethal smashes. The girls also notice that Agari is concerned over Kumami, who refused to play against her when she transferred to Tsumebame Girl's Academy. Encouraged by her friends to do everything she can before facing Tsumebame in the national qualifiers, Agari aims to improve her smashes.
