So about that Book of Atlantic scene… (in my Dadbastian AU)

For @sebaschian

When the Undertaker slashes his death scythe right through Sebastian, nearly impaling him, the cinematic records that fly out hold the memories of when Sebastian started raising little baby Ciel.

From when he found him in the mansion fire up to when the Queen allows him the right to adopt Ciel but only if he remains with the Phantomhives.

The best part is… Ciel sees them. He witnesses all of Sebastian’s memories in front of him, he notices all the small details of what Sebastian went through to become a good father to him. And now the thought of the only parent-figure he ever knew is about to die before him terrifies him.

Sebastian uses his strength to catch his child before he fell to the ground by himself; he doesn’t move an inch after that. Ciel quickly gets up and starts shaking the demon’s shoulders, he calls out his name twice:

“Sebastian! Sebastian!”

Nothing is said or moved. So Ciel gives in to his sadness and with no hesitation, cries:

“Father!!”

Then and only then does Sebastian open his eyes.

Thinking about dadbastian... It’s the primordial evil entity deciding that this human child is worth protecting and nurturing, even though it goes against his very nature. And that this human child deserves to be loved despite the fact that he sees himself as unlovable for what he’s done and what he’s been through. And the one who he thinks will drag him to hell is actually the one trying to help him through his worst moments. And even though a demon is definitely not an ideal parent to raise and teach a child, he’s going to try anyway because he knows that child needs him, and he won’t leave him no matter what, no matter how that child may push him away and say he doesn’t need anybody to love him and that he’s fine being all alone, when he’s really just a traumatized kid that actually desperately needs a parent to love him and guide him through life...For me🙂

Familiar AU Sebastian upon finding Ciel:

[moneyisthebestlawyerinh3ll]

Okay so I recently watched jingle all the way and it’s my new favorite movie but now I can’t stop thinking about if it was Sebastian as Arnold Schwarzenegger and ciel as his son and so enjoy this

[silvernsold]

tangential dadbastian. pretend this follows any of the prompts even a little. heart

[lisa-vitares-arts]

after the announcement of the new season i got kinda thrown back in to the black butler fandom and then i discovered the dadbastian tag which even if it is an au i found it to adorable to pass up the opportunity to draw something for it xD so i did

No ship art!

[nullbutler]

@cosmiclion. Hiiii sets this down

[anewp0tat0]

late as per usual, but this was April's theme back at the Black Butler Animo: (video)games!

I chose a game that not so many people know but still is my favorite game so far(I mean sure I haven't played so many but whatever) so yea, I'm gonna chose it as an AU. the dialogue is pretty weird cause I'm trying to cram exposition in there lol, but whatever, hope the art's fine atleast.

*ciel speaking*

*sebastian, then ciel speaking*

Human Sebastian AU where Human Sebastian is not even big into sugary things or junk food but.... finding out they're diabetic because it runs in the family ect ect and he already seems sickly half the time and overworked, now he has to be extra careful and the OCD is a mess and friends want to help but they having no experience can't ACTUALLY technically help and and-

The son carefully comes in one evening Sebastian is curled up in bed, tired and overwhelmed and depressed and still processing.

And says "I... I'll try to lay off the sweets a little... Um... if that'll help..."

Of course he has no idea if this is helpful. But... he's trying something he would never normally do. Trying. For SEBASTIAN.

Sebastian uncurls and turns to face the boy in the doorway.

And slowly opens up his arms.

"Come here you."

And the boy holds Sebastian back tighter than usual. As if afraid. Afraid his mother/father will.. fade away. Disappear because of this new, scary unknown.

This scary new development that has actually managed to shake up Sebastian Michaelis.

More info coming soon.

[natsuki208]

Sebastian: Humans are such weak animals. They are like nothing compare to us demons - so easily tempted and very conflicted.

(Baby Ciel starts crying in the background)

Sebastian: Hold on, little bluebird! Papa’s coming!

Dadbastian vampire au I've had in my head for a while. It's inspired by Interview With the Vampire and Lestat and Claudia's relationship.

So basically Sebastian is a vampire and he stumbles across the cult while they're doing their whole summoning thing, they think he's the demon they've summoned, until he starts feasting on them. He kills the entire cult and then finds poor traumatized O!Ciel who has been through that whole month of torture as well as his brother being sacrificed in front of his eyes, AND watching that whole massacre. (unlike Lestat Sebastian makes a mess of things)

When Sebastian finds O!Ciel he tries to put him out of his misery by draining him. He finds Ciel's little heart rather tenacious though which piques his interest, rather impulsively he decides that he could make Ciel into his vampire child. Sebastian has been in search of a companion for a while, but because he's such a narsasist, he can't fathom actually having an equal loving relationship with someone. So he figures having a vampire child would be entertaining and easy to control-Ciel does not turn out to be easy to control lol. Sebastian frames it like he's giving Ciel a choice in the matter, he can either join him as a creature of the night or Sebastian can end his suffering once and for all. Traumatized Ciel doesn't know what to do at first, (he also has had half of his blood drained so that can't have helped his decision making process) He feels extremely guilty that he, the useless spare survived and his older more capable brother died. O!Ciel just wants to die at first, to leave this cruel world behind, without his brother by his side there's no point to keep going. But then he starts thinking about revenge and the power that being a vampire could offer him, he thinks about how R!Ciel wanted more power to protect them. He finally decides that he wants to "live" for getting revenge under his older brother's name, so Seb turns him...

I'm gonna split this into two posts cause I have a lot more to say about this but it's getting long! :)

[cosmiclion]

I know Sebastian is very refined and committed to the aesthetic, but I really want to see him as a horrifying feral monstrosity more often. Give me more monster dad 🙏

[bull-shit-suji]

kuro modern au stuff that i word vomited into my notes app

kind of a Vincent summoned sebastian to save ciel so ciel doesnt actually owe sebas anything

amnesia? idk

single dad moment! except theres this other dad whos kinda find.. (cough agni)

i think vincent was like do NOT let ciel know ur a demon so sebastian keeps it a secret but he doesnt have a good handle on like. Humans. so he kinda does a bad job and ciel definitely knows that he's weird but doesnt say anything. will go out of his way to gaslight you when sebastian does weird shit because he thinks its funny

"hey uhh is your dad levitating?"

"no?"

"he's flying above the school rn"

"that's a bird"

u think suddenly being a butler is hard? have fun being a dad bitch

alois is there but thats complicated. claude and hannah are DIVORCED but on decent terms (i think claude is like. toxic alpha male podcast type guy) and claude sees alois on alternating weekends!

are they demons? i dont know

i think ciel and alois can be friends. platonically. alois would probably say yes if ciel wanted to be romantic but i Promise you he does not. they are just pals :)

im saying ciel has a crush on elizabeth because i can (she's not his cousin here). emo boy x sunny church girl. said sunny church girl has to ask the mcdonalds employees for the blue raspberry slushie they forgot to put in ciel's order because emo boy is too scared.

IM 13 EVERYTHING SUCKSSSSS

grelle is actually living her best life transitioned with anne so they are ciel's aunts on his late mom's side. i think grelle likes ciel. mom figure moreso than anne is.

ciel owns four bongs and definitely a vape or two. come on now

he's also probably got celiac and is lactose intolerant he is just a feeble boy i think

he listens to twenty one pilots. sorry! sorry.

ciel is goth alois is punk those r kinda just the rules

ciel is insanely smart top of the class this shit is easy for him.

yells at sebastian daily. figured out what happened with his real parents around the age of uhhhh 12 or 13? has been an absolute terror ever since

"it was really nice of your dad to bring cookies for the field trip!"

"i hope he fucking chokes on one"

"oh!"

sebastian and claude are pta rivals.

"is this lemon bread store bought? my, how... efficient!"

"you made these from scratch? i can tell."

"i've never seen an interesting looking salsa! very exciting."

ciel purposefully invites alois over constantly bcus it pisses sebas off. alois is Terrified of that man.

"go grab the chips from the kitchen"

"but... what if mr michaelis is in there?"

"mr m- you mean my dad? tell him he can shove a faucet up his ass"

"id rather die on the spot"

sebastian will yell at ciel and is maybe a little emotionally unavailable but he's trying!!! it's hard :(

does that Dad thing where he comes into ciels room and is like hey bud......... what r u up to..

ciel and seiglinde r also palls. the smartest people in school

lizzie is a JOCK. she plays softball.

alois is a theater kid come on now

ciel is best at writing and literature analysis, specifically fiction. enjoys history, language, and Some sciences as well.

nerd

au where myspace is still a thing ciel has a myspace account

he definitely writes shitty poetry

wants to major in business

alois is a glee and pitch perfect truther

[sebaschian]

Professor Michaelis doesn't have baby Ciel handed to Agni during class, he has him in a sling tied to his front. He doesn't like giving the baby to another adult.

Ciel is his son. Finny as well.
