The Adam and Eve is indeed a plan of Karl Heinz, in the MB game Karl wants all of his sons, that means the Mukami's too, considering they are his adopted sons, to learn how to love and trust a human after he and the mothers of the left a rather big scar on all the boys.

For the Mukami's one of them lived in the sewers until the army found him after he looked out to see what the ruckus was about, one of them has no memories of his actual life and ended up on streets and later in the same orphanage as the first I mentioned. another one got picked up almost the same when the group of gypsies he was traveling with vanished and lots of his friends hanged. the last had to see his father commit suicide, his mother run off with a stranger and all of his servants loot the house while they left him alone on the streets for surival

in the anime season of MB yui is a human, in the first anime season she turned into a vampire

in the games it depends, she either turns to a vampire or lives a human or is taken over by cordelia,

hope this clarifies it
