Being enamored with his father Goro, who once even played in the Major League, Daigo joins the "Mifune Dolphins" baseball team.
However, with the pressure of measuring up to his father, he can't improve enough and quits after less than a year and turns to an uninspired lifestyle.
Then, in the spring of 6th grade, a transfer student from the United States arrives.
The new baseball anime you've heard so much about is finally ready to play ball!
They've replaced tomorrow's pudding
with mozuku seaweed, right?
غيروا حلوى بودنغ الغد بأعشاب موزوكو البحرية، صحيح؟
Morgen gibt es Mozuku-
Seetang-Pudding, oder?
Cambiaron el pudin del almuerzo
de mañana por alga mozuku, ¿no?
Cambiaron el flan del almuerzo
de mañana por alga mozuku, ¿no?
On aura du flan aux algues
à la cantine demain, c’est ça ?
Al posto del budino, domani ci sarà 
un contorno di alghe mozuku, vero?
Trocaram o pudim de amanhã,
agora serão algas mozuku, né?
Завтра вместо пудинга будут модзуку.
