With it now obvious that he's having unexpected effects on his peaceful home world, Takeru has to make a tough decision.
I can't think straight. 
My head's all jumbled up.
.لا أستطيع التفكير بوضوح. رأسي مشوّش
Oh nein, ich bin ganz verwirrt.
Es inútil. Todo me da vueltas.
Es inútil. Todo me da vueltas.
C’est le chaos,
j’arrive pas à réfléchir.
Non riesco a pensare, 
la mia mente è sottosopra.
Não consigo pensar direito.
Minha cabeça está toda confusa.
Не могу думать. В голове бардак.
