You've Mentioned That Sebastian A A Very Powerful Demon And That Charlotte Is The First Of Her Kind.

You've mentioned that Sebastian a a very powerful demon and that Charlotte is the first of her kind. This makes me wonder whar exactly is Sebastian's position in Hell and what are its denizens reaction to his husband and child? Do they cause trouble? Do they keep away out of fear? Love your AU to pieces!

Hiiii Anon! Thank you so much for liking this AU! And sorry for the late reply!

Well, since Hell isn't exactly like human's society, it's hard to equate. But if I have to compare, I'd say that he's like an Arch Duke or a Marquess in Hell.

Oh, Hell doesn't take kindly to the news of Sebastian's progeny being carried by a human pleb. It's a shame to its denizens. To fool around with human and use them for all sorts of pleasures, sure. But for someone so strong to sire a child with such weakling, a hybrid at that, it's unspeakable abomination!

They tried many times to attack and end both Ciel and the child's life. If Ciel thought he had a huge target on his back before being the young Earl Phantomhive and the Queen's watchdog, that was nothing compared to this... Hell and heaven both out for his blood. But of course, Sebastian handled them all; absorbed all his brethren into the endless shadows of his being with such ferocity never seen before in the ancient entity. Eventually, Morning Star understand that Sebastian was not relenting his protection on the boy and his hybrid child, and wanting to see how this hybrid might survive, maybe even disturb the set order of the universe, he ordered the demonic legions to stand down.

But that doesn't means all is well for Butler and Earl. There's yet another struggle they're faced with; this one isn't so easy to deal with by force.

As I have said before, the demon fetus, with its demonic appetite feasting on human life force, is nothing short of a parasite. The reason Ciel was still alive was because the fetus needs him. The moment it’s no longer reliant on its host, it will kill Ciel. As such, at the beginning of the pregnancy, Sebastian wanted to remove the thing,(he'll even do it without Ciel's consent, just to see him live a bit longer, despite knowing Ciel will hate him). But Ciel saw through him and ordered Sebastian to protect them both. Sebastian could only obey. But he hated that parasite and was struggling to come to terms with the fact that Ciel’s already short human life (and their time together) is cut even shorter still because of this thing. And Ciel won’t let Sebastian save him, just because it’s theirs. Just because it’s his. Human are so different from Demons like that.

For the first time in eons of existence, Sebastian learned to mourn. And what a weird thing that was, when Ciel is still right here. But the end is nigh and it’s inevitable.

Sebastian is unsure whether he could ever come to love a thing that would take Ciel away from him. But Ciel is confident that he could, and he would. It’s their child after all.
