#also seeing atlantis is hecking cool and i accept that headcanon

I hope it's alright if I write a little of my own thoughts(which can very much and very easily be ignored especially since no one asked for my opinion😅 so do so if you wish!!) and add on a bit.

what's being said is interesting, however I would like the bring up one of the most commonly known facts on Yana Toboso's kuro demon(s???). the fact is that demons view humans as simple farm animals, or insects. like I said I know that most, and especially OP here, know this fact, though I feel it would be a relevant point of view in a possible answer to this question. the anon mentioned the demon witnessing all types of wondrous and very very horrific human behaviors throughout the years, and I agree with what they say. if an immortal human had to witness all that, I don't think any type of therapy would save them(unless they were psychotic or sociopathic). however, while OP is correct that our clad butler does experience a range of human emotions, which I do believe can grow as he learns, I don't believe that would make him take a mental toll on watching centuries of humans do horrible things. to try and sum it up, it's like watching a very dramatic and sad movie with ants and ants only. we can feel for them and feel sorry for them to an extent... but in the end, it's a movie. sure the main ants whole family drowned and their only hope for refuge got swallowed, but to us watchers, we get to live another day. well cry over the movie for a day at most, and eventually forget it. now, let's say it wasn't a movie, but you actually watched a pack of dogs go to war, and you could hear their thoughts and speak their language. dogs are great, so if I had to watch that I would cry for weeks and morn them. but because there's a species barrier, you can't feel them and their loss on a personal level. though the gorey images of the battle field may stay with me for years...

when you're an immortal demon, I imagine such wars and disasters get repetitive, when they're from a distance. as OP said, I don't believe eternity is pleasant even if you are Sebastian.

and to cover what OP said about past masters, I do agree it would be quite dreadful and irritating at times. however to bring back the weird animal analogy, I imagine that for canon Sebastian it could be compared to being enslaved by a puppy who nibbles and barks at you whenever you do something a little wrong. annoying, exhausting, kinda funny, maybe, but you can't exactly take it personally cause it's a puppy, what does it know about me, it can't insult me, it'll die before me and it's nibbles barley hurt. ofc that's just my perspective, and I could be wrong.

but now focusing on what OP mentioned about the undertaker. because that is an up close and personal conflict, that affects and dangers him as a species, I think there's every reason for that to leave a scar in their memory. as OP said, I doubt it's the equivalent of human PTSD, but remembering such a time of desperation must not be pleasant at all.

so, ugh, yea, I wrote so much I'm sorry😂😭 to conclude, I think what I'm trying to say is that while the canon demon will remember and understand the pain, it will not affect then on a personal level(unless the threat is personal, ofc. so who knows maybe this story specifically would give him some form of PTSD. and honestly I hope i does- not PTSD ofc, that's awful for anyone, but it would be nice is sebas could feel or learn something once all this is over. )

(I think it's also worth noting that I am no expert of PTSD or psychology so yea everything I just said may be incorrect)

all that being said,

for fanon actually-feels-something-sebas...

heck yea LET'S GET SOME NICE HEALTHY ANGST

another thing people never think to explore, the demon? who has seen the world change and evolve over a million times, dynasties fall, powerful amazing towns or civilizations just get destroyed or something (like maybe he saw atlantis on the surface world!!) and everyone thinks no way can a DEMON have ptsd or something like it, even though hes lived through SO MUCH, seen SO MUCH DEATH. like we could never handle what he has seen. but can HE handle it?? Really??

This is an excellent point, and one that is often ignored in fic and canon alike (dang it, Yana). Sebas is cold, arrogant, and generally lacking in empathy, but he’s still capable of experiencing emotion. What about instances where he might have been abused by past masters (since a demon under contract is obligated to fulfill their human’s every whim)? How might that have impacted him...especially since demons probably don’t have access to anything remotely resembling therapy in hell? And we see in the manga that Sebastian was badly shaken by his experience with Undertaker aboard the Campania. In the Weston arc, for example, shortly after learning that the headmaster is actually Undertaker in disguise, Sebastian begins panicking, worrying what might happen if the reaper snatches his young master away like last time. Notice how similar these panels (Sebastian rapidly playing out a detailed what-if scenario in his head)...

...are to these panels from the Campania arc.

While I’m not sure this would qualify as a full-blown PTSD episode, that painful battle has clearly been etched into the demon’s memory. Little wonder the butler looks so distraught!

Although Yana’s demons appear to be eldritch entities that were never human to begin with, I also wonder what their experience of eternity is like, and whether they (or the reapers!) grow weary of the relentless cycle of change and destruction and rebirth among mankind. To jump series, it makes me think about the psychological toll of immortality on Anne Rice’s vampires, and how some eventually sought death because they couldn’t endure the eroding away of everything they once knew. Just because a creature can live forever doesn’t mean that their eternity will be a pleasant one...
