Undertaker went rogue about 50 years ago which fits with the timeline.

Now those were the big, blatantly obvious hints, but there are many smaller ones that I'll list now. maybe because they weren't married? (oh scandalous… XD) Because Undertaker was a shinigami for a while before going rogue.Īnd while we're at it… since when is the name oft he mother kept after marriage? Not in this time they weren't…. And more importantly, the years of his life. Phantomhive but the name of Vincent's father is obscured. And in the picture in the manga we see Claudia Phantomhive, mother of Vincent

Yes, they also mention that due to the pact with a demon Ciel can be considered half dead, but they do point out the family tree in addition tot hat. At first thy wonder how Ciel can see them so readily, however after checking his family tree they are no longer surprised. Now back tot he german shinigami in the green witch arc. Now why would he have that if not because she had meant a lot to him? There is definitely a connection between Undertaker and the Phantomhive family. It carried the lock of Claudia Phantomhive, Vincent's mother.

Next let me remind you of the necklace the Undertaker lost to Ciel on the sinking ship. Now why would a rogue shinigami cry over a mortal? Because he isn't just any normal mortal. I'll start with the scene from the Green Witch Arc in which Undertaker visits Diedrich.

Lemme read your mind real quick… yeah, I need to explain that one, don't I? no problem. Undertaker is Vincent Phanotmhive's father and Ciel Phantomhive's grandfather. So I'll start with my deduction, and then offer the explanation and sources afterwards.
