Talk:Shinyaku Toaru Majutsu no Index Light Novel Volume 08/@comment-7719364-20131104094321

Touma wakes up in a world where the supernatural doesn't exist, there are no espers and magicians, and everyone including him have no memory of the previous world including himself. As he goes about his everyday life, he starts receiving these mysterious visions involving the people around him doing things one can only find in a sci-fi novel. Unbeknownst to him, these visions are memories of the unwarped world, slipping through the cracks in his mind that the Imagine Breaker made before the world was changed. Initially brushing them off as delusions, the visions become more frequent, until he starts to doubt his own sense of reality. In effort to break his own illusions, and erase his doubt, he begins searching for answers until he comes across a mysterious one-eyed girl.

That's my theory on volume 9.
