The Mifune Dolphins improve their teamwork a bit during a practice match before the summer tournament, which improves their confidence.
On the other hand, having had to transfer to his mother's hometown in Gunma, Hikaru is separated from his Dolphins teammates and was having unhappy days.
In front of his grandfather and mother he bravely put up a cheerful front, but even when he is invited to join the school baseball team, he refuses right away, saying he's not in the mood.
That way, I'll also never forget 
that I am my father's son.
.هكذا لن أنسى أبدًا أني ابنه أيضًا
Ich möchte auch so nie vergessen,
dass ich sein Kind bin.
Así nunca olvidaré que soy su hijo.
Así nunca olvidaré que soy
Comme ça, moi non plus,
j’oublierai jamais que je suis son fils.
E in questo modo, nemmeno io dimenticherò
Assim eu também nunca
esquecerei que sou filho...
К тому же, так я не забуду, кто мой отец.
