Sikon!!!
Your fanfic is just great, I don't know what else could I say.
Finally I know the origin of mysterious Yggdrasil. I especially liked the whole idea with Bifrost and the link that you made to the M.O. Zwei scene of Nina's teleportation.
Thanks a lot, good luck with next chapters!
(I wonder why are Searrs (and anime creators
) so fascinated with Norse mythology (I saw Yggdrasil in some other anime, too)
