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?
If I'm still where I was when I blacked out.
هذا إن ما زلتُ في المكان‏
الذي كنتُ فيه عندما غبتُ عن الوعي
Wenn ich noch da bin, wo ich
das Bewusstsein verloren habe …
Si es donde me desmayé, sí.
Si es donde me desmayé, sí.
C’est là où j’ai perdu connaissance.
Credo di essere ancora
dove ho perso conoscenza.
Se eu ainda estiver no 
lugar onde eu desmaiei.
