The preliminary match of the Nationals is finally approaching. Etsuzan Highschool’s opening is Taki Highschool, who lost in the first match. Nagumi (Ryohei Suzuki) uses the lead coach, Yokota (Katsuhisa Namase) as a cover to direct the team under the guise of sub-coach. He has made up his mind to quit being a teacher after this tournament. Thanks to the work of their ace Sho (Motoki Nakazawa) and the other freshmen including Kugahara (Yuki Tachibana) and Nire (Shupei Ikuta), Etsuzen is in the lead!

Meanwhile, Mika (Haruka Igawa) decides to leave her children with Nagumo to go to Tokyo, but their son Aozora (Tenta Banka) who does not know the complete situation says he is reluctant to go to Tokyo…
