Interestingly, while Cheri expresses some unhappiness with Dan Hiri up and leaving her, her essential complaint is that he aged faster than her, and died an old man while she remained young.

...I agree with you about Cheri, and it's an interesting question: do you think she loved him in spite of his limited time with her, or because of it? One gets the feeling that she obtained a certain experience from him re: life (and death) that the other Mazoku don't seem to have--even the oldest of them know no more than children when it comes to mortality, given the ages they live to. Conrad might be able to relate to that via not only his father, but also the half-Mazoku only battle where he lost all his men.
