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?
You're the one who decided

أنتِ من حدّدَ طريقة موتهم، صحيح؟
Du hast über ihre
Todesart entschieden.
Fuiste tú quien decidió cómo matarlos.
Fuiste tú quien decidió cómo matarlos.
C’est toi qui m’as dicté
la façon de les tuer !
Sei stato tu a decidere
come uccidere le vittime.
Era você quem decidia 
como eles morriam, não é?
