You know now that I think about it, wouldn't the plot have been better if you were not only a kue-jin, but a kanbujian? Makes more sense than weird magic soul incest.
It would explain why you could freely learn any discipline, with an ability to fully "devolve" into a cainite clan.
It would also explain a lot of interesting hooks. Like kue-jin interaction with you (they will literally fucking murder you not just out of piity but out of Vampire CCP anger). And a secret magic ending akin to revealiing the Taxi Cab driver was Cain.
You're not a kue-jin at all, but a full blown solar exalted, exaltations and all. It's just the World in World of Darkness is so shit you've become what is essentially a parody of what you were and what you should be as the messengers (100% angels, one of which might be gaia herself [which would then let you add a werewolf pastiche since they won't INSTINCTUALLLY murderfuck you like other vampires) attempt a new version of imbuement.
Alongside this being the reason you either rise in bloodline or whatever asian soul vamps have. 13-8 bloodline is nothing if you scale it on Essence 0 - 1
There: World of Darkness gets to advertise literally everything a la BG3.
And we finally get lore tying the grimdark shitheap to Dragon Ball Z land so I can finally be happy
I really do wish they delved more into actual lore as well honestly. Like the history of cainites is so fucking awesome in WoD - in that, Cain wasn't just the first sinner, he invented murder. As in he taught angels how to kill. As in, in a way - he was more responsible for the War in Heaven than even Lucifer ever was (because the implication is not even Lucifer fathomed the concept of killing his peers until he saw Caine do it to his brother). Which is probably why God hates us here. So much so that he invented weirdass shapeshifting angels to not only murder angels in retaliation. But left them there as halfbeasts to predate on humans.
That's right, God hated humans so much he might've invented furries.
