Hikaru says he wants to be a pitcher because "it looks fun". Despite his terrible grip and form, his brutally fast balls are something to be reckoned with! After appointing Daigo his training partner, Hikaru casually suggests that the two of them form a battery.
Daigo refuses the idea as impossible, based on his arm being weak. However, his sister Izumi points out that his personality and knowledge of baseball would actually make him a good catcher.
Look here. Why do I have to go 
that far just to catch for you?
اسمع. لمَ علي أن أصل إلى ذلك الحد
وأمسك الكرة لك؟
Weißt du …
¿Y por qué tengo que atrapar contigo?
¿Y por qué tengo que atrapar
tus lanzamientos?
Et pourquoi je suis obligé
de te servir de receveur ?
Mi spieghi perché 
devo sbattermi così per farti da ricevitore?
Se liga, por que tenho que me esforçar
tanto só pra jogar com você?
Эй, почему я должен
так распинаться ради тебя?
