So your take on Amelia is a version where she "Disappeared and went to the root". No wonder she is a Foreigner, and since Koishi explained to me before the prequisite on how one became a Foreigner-class servant, i think i understand a bit.

I'm kind of curious of  her NP though. So her NP is a plane which allows the travel to an unknown dimension?
