Oh, that cheeky dickwaffle.
He gave her Reincarnation, but the Reincarnation is of her divine self, so there's literally no downside to it. It's three free Orbs of benefit for the price of 'One' and gives her at least limited access to her godly powers. It's a loophole they can abuse because they grab someone from outside the system to be the opposite number, and thus to be 'Fair', they have to do the temporal loop shit, and that leads to our prior-incarnation hating us and fighting every step of the way.
After all, the flaw to Reincarnation is that we're coming from outside the system, so he has to basically do a temporal loop on our self and then send that soul fragment through a long and drawn out hell that'll piss the soul fragment off. It's fair and balanced because he gives exactly the same treatment either way, but in order to superficially appear fair, he can give it to us in a manner that taints it, and limits the benefit we'd receive from it.
This might very well be precisely why they grab someone from out of the universe to play this game. So that they can effectively wall off the best option from them and ensure that even if you take it, you don't get as much benefit out of it. "Sure, you can take it, but it's going to fight you every step of the way."
Hell, we've been outright told that she works on the Reincarnation spectrum. And there's no reason why her Prior Incarnation would hate her.
So yeah, I think that was her core build. "Reincarnation" plus "Young Master". But her Reincarnation has no penalties simply because of how they gamed the system. So she spends one Orb to get three Orbs when she matures at no further expense or effort, while we have to pry every scrap of advantage out if we do the same thing simply because our prior incarnation hates us while hers is identical to her current incarnation.
It would explain why her brother only popped in for those two options and then lost interest. They probably would love to pull a kind of "We give the same benefits, but yours are less beneficial than ours" horseshit.
