One thing I find interesting about the name of the Ghoul Prison “Cochlea” is that it’s the same name as the small spiral organ in you inner ear. Maybe because of it’s spiral shape, maybe because they generally “hear” information from their prisoners.
Then I thought about Kaneki who is known as “Centipede.”
So then if Kaneki/Haise is ever captured and put in the Ghoul Prison. “The Centipede is in Cochlea.”
