高校のハンドボール部の試合に出場する瞬を応援するため、颯と貴之が会場にやって来た。ところが、瞬と仲がいいはずの蒼真の姿が見当たらない。どうやら蒼真は試合会場に向かう途中で電車を乗り間違えたらしい。この日のためにテスト勉強に励むなど頑張って来た瞬は、もうすぐ部活を引退する先輩たちとひとつでも多くの試合を戦いたいと意気込むが、その気合は空回りしてしまう。
"Hayate and Takayuki have come to the stadium to cheer Shun on in his handball tournament, but for some reason Shun's friend Souma is missing. It turns out that he went onto the wrong train... Meanwhil Shun is really fired up about winning as much as possible to prolong being together in a team with his teammates who will retire after this event, but the hype backfires and he can't quite perform right..."
Chegou o grande dia para Shun! E valendo a tão sonhada vaga no intercolegial, o rapaz quer fazer bonito pra todo mundo ver!
Shun will seinen Freunden beweisen, dass auch er cool sein kann. Seine Bühne ist die Turnhalle, Handball seine Disziplin. Dummerweise steht einiges auf dem Spiel, was eine gewaltige Herausforderung für seine Nerven ist.
