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?

Es tut mir aufrichtig leid.
Lo siento mucho, de verdad.
Lo siento mucho, de verdad.
Je suis désolé…
Perdonami davvero...
Me desculpe de verdade.
