Everyone at Ryokushou is participating in the Miyama school district's sports festival. Itsuka feels shy and awkward around Nagomu, causing her to adopt a brusque manner toward him. But in his loud cheers of encouragement she feels the warmth of family. Nagomu's father, Heigo, gets overly fired up and ends up hurting himself. Nagomu and Itsuka have to step up to take his and Nagomu's place in the parent-child event. Meanwhile, at Ryokushou, a woman calling herself Itsuka's mother appears.
But we're basically like parent and child,
،لكنّنا كأب وابنته عمليّاً
Na ja, wir sehen ja
wie Vater und Kind aus.
Pero nosotros parecemos padre e hija,
Pero nosotros casi lo somos,
Bah, t’es un peu comme ma fille, non ?
On pourrait la faire ensemble.
Beh, noi siamo un po' come padre e figlia,
Mas a gente é basicamente pai e filha,
Мы с тобой почти семья, 
значит, сможем участвовать вместе!
