Yes, he did. I've read all 10 volumes about 5 times now, to the point where I pick up on the little subtle things Akino-sensei likes to throw (sneak) in...if you've read Shin, there is an image before the Berlin story of many Counts, or perhaps just a few...and Grandfather is there, as well as a very HOT D.
And I'm wondering when you'll post the next one...?
