Inui has never been able to defeat Tezuka in their 20 or 30 matches since they joined the Seigaku tennis club. But today, Inui surprises everyone by showing just how much he himself has grown in his match against Tezuka.
In other words, he was building up
his own body, as well.
Mit anderen Worten hat er also auch
seinen Körper trainiert.

a aumentar su fuerza.
En d’autres mots,
il a aussi entraîné son corps.
Ou seja, ele também estava fortalecendo
o próprio corpo.
