I'd back up that campaign!
I wonder about that too, though maybe not quite hitler only the mustache really. He sure grew fat in his old age though.
It's kind of nice to have go to a different part of the world rather than stay in England the whole time. More diversity, like if they visited India with Soma, that might be interesting. (I was confused at first by the chibi with ten lines for eyebrows bit since I've never seen hetalia. XD)
I half wondered about it but kind of went along with since if there are already grim reapers and demons, might as well there could be werewolves.
With Diedereck around now, who was probably closest to Vincent as far as we've seen, we'll probably get more insight into who could've been targeting them at the time.
Well I'm guessing this is a typo but if it's black in the manga then they'd be coloring it right then. Though I started only reading the manga and was used to tonal on hair to convey it was red, so I thought his hair was red and couldn't wrap my head around him having bluish-black hair after seeing the Vol. 6 cover XD
I'm sure we'll learn about Sebastian and the Undertaker even more as Kuroshitsuji progresses i doubt it's very close to its end since we don't even know Baldroy and Mey-Rin's stories yet. Though I bet Sebastian didn't have a name, that demons just flit from master *cough*prey*cough* to master acquiring names as they go, it would be interesting to see some of his old masters in a flashback though.
I wonder if Undertaker will be addressed more in the next arc with Claudia. I doubt Madam Red will return, we're probably moving on to the rest of Ciel's family with Claudia now.
She really does exploit him doesn't she? XD Though he probably just sees it as his duty as the Earl of Phantomhive to do her bidding anyway. Why else would he be called her guard
dog? XD
Sorry for the long reply
