Alright Araragi, it’s time to figure this shit out. As I’ve suspected and Hanekawa seemed to confirm, this world we’ve been exploring is less of an alternate reality than an internal one; a product of Araragi’s mind, as he desperately seeks an answer to that fundamental question of “who am I, now that my childhood and pre-scripted path are behind me?” In search of that truth, he has held discussions with disparate versions of many of his companions, but avoided the one person who might truly know him well enough to answer: Oshino Ougi, his own Other Self.
As with all of this world’s Oddities, Ougi has served as a container for all the feelings Araragi refuses to acknowledge, a shadow that is as authentically him as his surface personality. His self-hatred and obsession with his own destruction, his lingering regrets regarding the possibilities of his vampiric nature, even his inability to visualize himself as an authentic and consistent person are all realized through Ougi’s mercurial presence. Araragi has come to accept Ougi’s authenticity as a part of him, but has nonetheless avoided their input in this crucial moment. As Sodachi said, what we see in the mirror is only a partial reproduction – Araragi is incomplete without Ougi, so it’s no wonder he’s only been able to produce incomplete answers. With his two sides united at last, let’s see how this strange mirror tale ends!
