I have to be strong to save everyone.
يجب أن أكون قويّاً لإنقاذ الجميع
Ohne Stärke kann man nichts retten.
No puedo salvar a nadie sin serlo.
No puedo salvar a nadie sin serlo.
Sans ça, impossible de les sauver.
Senza forza non si può salvare nessuno.
Se eu não for forte, não posso salvar.
Только сильный способен спасать.
