change; before/after

Full Summary: Sousuke spends eighteen thousand years locked up and it changes his perspective on several things. He's stuck in the lowest level of Muken without any interaction long enough that he's gone past insane. He doesn't talk to himself, doesn't mutter replies to hallucinations, just sits there, his eyes closed. All he does is think. He thinks for so long that at one point, he's not sure what it was like to not think. To not have only his own thoughts be his constant company.
