To the moon! That's the plan, at least. Senku and the Kingdom of Science need to devise a means with which to go to the moon and deal with Why-Man. The first step is allying with the people of Treasure Island and enlisting their help with some new crafts.
That's a requirement we can't work around.
.إنّها ضرورة لا يمكن تعويضها
um zum Mond reisen zu können.
c’est d’avoir plus de main-d’œuvre
que jamais.
Ed è una condizione indispensabile
 per arrivare sulla luna.
Este é um requisito inegociável.
Это обязательное условие, его не обойти.
