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?
He took away the test subject's 
senses of sight, hearing, and touch.
جرّدَ حواسَ البصر والسّمع واللّمس
من رعيّة التجربة
Er nahm den Testsubjekten
ihren Seh-, Hör- und Tastsinn.
Se priva al sujeto de vista,
oído y tacto,
Se priva al sujeto de vista,
oído y tacto,
Il plaçait des sujets sur un lit
et obstruait leurs sens,
I soggetti vengono privati
di vista, udito e tatto,
Ele privava a cobaia dos sentidos
 da visão, audição e tato.
