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?
I should've mind-controlled you into 
the torture room to begin with.
كان ينبغي أن أتحكّم بعقلِك لتدخل غرفة
التّعذيب من الأساس
Ich hätte deine Gedanken schon damals
in der Folterkammer manipulieren sollen.
¡Debí haber guiado tus pensamientos
hacia la sala de tortura!
¡Debí haber guiado tus pensamientos
hacia la sala de tortura!
J’aurais dû contrôler ton esprit
dans une salle de torture.
Avrei dovuto condizionarti
nella sala delle torture!
Deveria ter te levado para uma sala de 
tortura assim que controlei sua mente.
