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?
What am I mind controlling 
you to do, exactly?
ماذا ينبغي أن تفعلي عندما أتحكّم‏
بكِ عقليّاً بالضبط؟
Wie genau soll ich deine
Gedanken kontrollieren?
Come devo condizionare il tuo pensiero?
Quer que eu controle sua
 mente para fazer o quê?
