With it now obvious that he's having unexpected effects on his peaceful home world, Takeru has to make a tough decision.
I thought everything was 
going to be smooth sailing.
.ظننت أنّ كلّ شيء سيسير على ما يرام
Ich dachte, alles würde glattlaufen.
J’ai longtemps cru
que tout irait bien,
Pensavo che sarebbe andato tutto liscio.
Achei que tudo ia dar certo.
Я думал, что мне всё по плечу.
