Has anyone else noticed the personality mix happening yet? CRAZY MOTHER FUDGING THEORY TIME! There will come a point when the two demons and mortal King are so entwined with one another that there personality's take on the traits of eachother. At some point something will happen and the realisation that the only way to beat H&E is for Noah to use his ability to absorb both DD and XE. It is that this point that Noah is on an evenish footing with those ancient beings. Noah can use both there laws for himself as they match aspects of his own law without causing his path to split.
Aceion:He will have to fight them to the death in order to even try and absorb them. He may be the leader but that's all it is. They mainly follow him because of his passive skill that excels their growth and his ability to attract enemies. There is no way they will allow themself to be absorbed unless author decides to break their character.
