I'll probably end up remembering this anime as the one that started my glasses fetish instead of an epic action romance..I really loved the scenes for Mirai's departure and return, made my heart race a bit.

I don't know how Mirai lived but I'm perfectly okay with the happy ending.
I'll agree that the ending was satisfying but lacked explanation, hopefully covered in the light novel. I did give it some thought..
well my theory about Kuriyama Mira's revival is that since she was capable of coming back just as a mirror image in Akihito's dream and the Beyond the Boundary's world it's possible that Mirai was able to revive again in the finale as a another mirror image. When Mirai's ring disappeared, Akihito unintentionally used Mirai's ring, instead of her blood as in the other cases, as the catalyst for creating an image of her. When Akihito was talking about darkness in light and vice versa, he could have been referencing to how he used the Beyond the Boundary's power as the malice of all humanity to bring back his beloved. The Beyond the Boundary can make entire worlds so one megane bishoujo should be a piece of cake..however it's still a mirror image seeing as Mirai is supposedly dead.
