Summer vacation has begun. The badminton team heads to Okinawa where the Inter-High is being held. On the plane, the third-years look back on the events leading up until this point: Yusa's first practice at Yokohama Minato, how he met Yokokawa, and Misaki Shogo. According to rumors, Misaki went to a high school outside the prefecture to get away from Yusa. Their plane arrives at Naha Airport, where Yusa runs into an unexpected person: none other than Misaki Shogo himself.
If we play each other in 
the future, I won't lose.
.إن لعبنا ضدّ بعض في المستقبل، لن أخسر
Wenn wir je wieder
gegeneinander spielen,
Si nos enfrentamos, no pienso perder.
Si nos enfrentamos, no pienso perder.
La prochaine fois qu’on s’affrontera,
tu m’auras pas !
Se in futuro giocheremo l'uno contro l'altro... 
io non perderò!
Se eu jogar contra
você, não vou perder.
Если мы будем играть 
друг с другом, выиграю я!
