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?
Just trying to struggle against 
his power did this to me?
حدثَ بي هذا من مجرّد مُحاولة مُقاومة قوّته؟
Allein der Widerstand gegen den Einfluss
seiner Fähigkeit macht mir so zu schaffen?
¿Esto solo por resistirme
a la influencia de los poderes?
¿Esto solo por resistirme
a la influencia de los poderes?
Voilà ce que ça fait
de s’opposer à ce pouvoir ?
E tutto solo per essermi opposta
all'interferenza...
Só tentar bater de frente com
 o poder dele já me fez isso?
