Random Kuro AU: The Cambion
I was having some late-night thoughts about the Kuro ladies (as is my wont), and realized there was one in particular who I’ve neglected and who hasn’t exactly received the best treatment at the hands of the fandom: Mathilda Simmons the nun.
Based on a couple of screenshots from the Hamlet OVA, some have speculated that Mathilda’s infamous roll in the hay with Sebastian resulted in her being pregnant with his child. This set my fic-writer’s brain churning. Let’s say there’s some truth to this theory. If she survived said pregnancy, what would the child be like, and what would become of this single mother? Thus the idea for The Cambion was born. (”camion” is the term used to refer to half-human, half-demon children, especially if the demonic parent was an incubus or succubus)
In this AU, Sebastian was genuinely attached to O!Ciel (in a platonic father/son sense), which compelled him to stay on Earth after eating the Earl’s soul. Out of compassion, the Midfords add him and the other Phantomhive servants to their staff. I know this is improbable, but make-believe land can have whatever you want. :P Around this time, a pregnant and desperate Mathilda shows up at the doorstep--as a single mom, she has nowhere else to turn, and strange, unnerving things have been happening to her. The other Phantomhive servants are shocked and disappointed in Sebastian, and Frances Midford reads Sebastian the riot act, making it clear there will be hell to pay if he doesn’t take responsibility and help Mathilda out. Sebastian is forced to confess that he’s actually a demon because even he can’t explain away all the obvious signs that Mathilda’s carrying a diabolical child. Mathilda is understandably furious and upset at being duped by the butler, but she resolves to keep their baby, and the other servants rally around her and (eventually) forgive Sebastian for deceiving them and devouring O!Ciel. Through circumstances that I need to figure out, it’s revealed that Mathilda has a latent aptitude for witchcraft; this, along with Sebastian’s efforts, enable her and the child to survive delivery. Babey turns out to be a son, who Mathilda names Eusebius (”pious”; he’s called “Eusie” for short). His character design is heavily based on Yato from Noragami. Eusie can be quite a handful; he’s a naughty little scamp with an unfortunate tendency to get into scrapes, much to his mother’s dismay. It takes a while for him to master his dark powers (he has a lot of “horsepower,” which is challenging to manage), even with Sebastian’s guidance, and his very presence tends to attract all manner of supernatural creatures to the Midford residence. As he matures, Eusie grows into a mighty warlock with a knack for necromancy. Sometimes, he can cruel and ferocious.
Most of the time, though, he’s a lovable dork.
Along the way, Mathilda would grow into a powerful witch in her own right and realize that she’s actually a lesbian (and maybe settle down with a loving wife). Though her relationship with Sebastian is rocky at first, they gradually come to stand on equal footing and put aside their differences for the sake of their son.
I have no clue what (if anything) I will do with this idea, but I thought I’d go ahead and write it into existence.
