The final battle takes place in the Hikariwo theater, where Takuru is trapped in a sightless and soundless prison in his own mind.  He'll need Onoe's help to break free, but after what he knows about her, can he bring himself to ask for it?
Probably the only chance you've got 
is the moment when you get back.
ربّما الفرصة الوحيدة السّانِحة لك هي
في اللّحظة التي تعود فيها
Ich glaube, wenn du ihn nicht sofort nach
deiner Rückkehr auf die andere Seite angreifst,
Cuando vuelvas en ti,
Cuando vuelvas en ti,
Peut-être qu’en repassant
dans l’autre monde,
Probabilmente, l'istante in cui torneremo di là
Provavelmente sua única chance 
vai ser o instante que você voltar.
