hey, so.... eek
I noticed something interestingly (if that's even a word xd ) strange.
It was in chapter 199, here --> http://www.mangareader.net/210-57824-28/dgray-man/chapter-199.html
and the effect of the spell was --> http://www.mangareader.net/210-57824-29/dgray-man/chapter-199.html (the gates' destruction)
Is it just my imagination or Allen really did use one of the "magic spells" that General Marian Cross always used?
(f.e. --> http://www.mangareader.net/210-15222-11/dgray-man/chapter-131.html )
It is also mentioned here (about magic):
http://www.mangareader.net/210-15218-3/dgray-man/chapter-127.html
http://www.mangareader.net/210-15218-4/dgray-man/chapter-127.html
etc.

share your suggestions and opinion, 'cause it's something worth investigating, I think... exclaim question idea
