Inosuke comes in peace, if you ignore the swords

Grelle’s name would be either “Grelle Sutledge” or “Grelle Sutwagon”.

She’s as celibate as a nun in winter.

No species swaps or name swaps that lack instant recognition (e.g. Sebastian’s name doesn’t become “Tanaka”). This means Sebastian remains a demon, albeit more virtuous.

Ciel’s last name is “Ghostnest”.

Could also be the real Ciel. Not our Ciel.

Sebastian: “Hey, Ciel! I made you cooki-” *SMACK*

Grim Reapers organise souls into newborns. That’s all I could think of for a “life” theme. Their eyes are purple.

Will is a messy trash goblin who’s office is a continuous wreck. He’s a wreck. Completely disorganised. Cries sometimes. Might be a bit of an alcoholic.

The Undertaker is a dedicated and well-known grim reaper. He’s nice enough, but is everyone’s superior officer / supervisor. Walks with his scythe like it’s a walking stick. Hates the idea of death.

What would his name be? Overtaker? Overgiver?

So imagine this is a canon universe (I mean Black Butler is basically an Addams Family anime, to an extent, with weird shenanigans and dark academia, and perturbed, out-of-place visitors in the Phantomhive manor, anyway), a crossover, where Sebastian interacts with Lurch; where Sebastian dances the culturally questionable mamushka; where the only things differentiating the Addams’ from the Phantomhives are blood and murder-lust; where Ciel or even Sebastian must question if any of them are potentially demons themselves, as some will not die, and some seem flippantly murderous and dangerously skilful.

Sebastian is HILARIOUSLY EASILY AMUSED. And I don't mean he'll laugh at any silly little thing or that he likes jokes.

But whenever Ciel finds himself in an awkward situation or says something the demon considers stupid — Sebastian LITERALLY CAN'T HOLD BACK HIS LAUGHTER. Like, to the point where he has to cover his face with his hand. And this has happened more than once or twice.

I'm really curious — is this just a Sebastian thing, or is it common for all beings of his kind? Has he always been this giggly? Does he genuinely struggle to suppress the urge to laugh, but he can't, or does he simply not bother because he knows there won't be any consequences for him?
