⚠️Long-ish post: Phantomhive Bloodline × Hunter Theory: A Possible Link?⚠️
The impression I’m getting lately, especially with the recent reveals and backstories piling up left and right... it's only a matter of time before Claudia Phantomhive gets hinted at somewhere and somehow (alongside her backstory too, by the way... because we really need more context on her.)
|f we're talking purely canon and completely setting aside fan theories: There's not much to work with beyond a death date, her being Ciel's grandmother, and a single ambiguous panel where we're not even certain it's her back.
(The mourning locket is technically another detail, though it doesn't expand the canon information we already have here, so I'm not really factoring it in.)
If demon hunters (assuming this concept is actually being implemented into the manga) and the Phantomhive ancestry are being linked, she isn’t really optional to the narrative anymore… she’s likely part of the wider plot.
If the lineage concept starts opening up, you can’t just gloss over the grandparents like they aren’t carrying half the lore.
Not in the near chapters (I don't think), but if a hunter theory develops (ahead in future chapters), we might get more focus on previously unknown details about past Watchdogs. That’d be the perfect opportunity for Yana to drop more breadcrumbs about her backstory/identity/past.
What could those details imply about who they were, their past dealings, their missions, and how they carried them out?
Also, what I’m getting at here is that if the hunter theory includes the idea that they can kill demons because they themselves have some kind of supernatural ability (or what not), it could also pave the way for an explanation of Undertaker.
We’re not exactly starting from zero here (the groundwork is already there) when the story has already hinted that O!Ciel himself may be connected to abilities beyond those of a normal human.
Conveniently enough, the manga first brings up the whole "one foot in the grave" explanation, only for the very next panel to immediately steer readers toward the idea that O!Ciel’s ability to sense Grim Reapers may actually come from his lineage instead.
Ngl, that one manga page alone pushed the grandfather theory up to like 85% credibility for me lol
BUT! The real question is whether Yana was foreshadowing Undertaker specifically, or simply planting the idea that supernatural abilities already exist somewhere within the ancestry itself.
Which would make the lineage panel even more meaningful, especially now that we know demon hunters may exist within the lore.
The fact that the family tree is literally sitting in the background while lineage gets hinted at feels WAY too intentional. I'd put my hand in fire that Yana did that to keep readers guessing between Undertaker and other bloodline-related possibilities. She loves confusing us, doesn't she?
The author has a pattern of keeping things ambiguous and unresolved early on, only to revisit them much later with a significant reveal that reframes everything.
Now, back to UT and Claudia and their very suspicious possible union...
Why would a legendary grim reaper care about a normal human girl? Perhaps she had "abilities" that set her apart.
I know this may sound a bit contradictory, but keep in mind we still don’t know whether the supernatural powers/abilities come from further back in the bloodline rather than from him directly.
Dumb lil side note: That reveal panel (maybe in the future) where Ciel’s entire identity, and the only reason he exists at all, is reduced to a Grim Reaper and his grandmother having "fun" is going to be absolutely epic.
That said, it would only apply to Undertaker if the grandfather theory proves to be accurate.😝
Phantomhive bloodline + possible supernatural traits = Undertaker connection or another source? Only time will tell.
All in all, if Yana starts pulling on the Claudia thread, Cedric's is likely around the corner too.
But of course, this is all just speculation, not fact. Oh great Yana, I really do wonder what you have in store for us.
I summon the council, fellow theorists, opinions?
