Souma is worried about his older brother because when he's focused on work, he neglects food and sleep. After discussing it with his friends, Souma decides to make a bento lunch for his brother.
I'll do my best.
سأبذل قصارى جهدي
Ich krieg das hin!
Debo esforzarme.
Tengo que esforzarme.
Ça me motive !
Farò del mio meglio!
Pode deixar!
Буду стараться.
