<<<<<<<<<<<<SPOILER?????>>>>>>>>>>>>>>>>
He is Hella's biological father. From what I remember from the novel summary, he found out about her too late (he had every intention of recognizing her as his legitimate heir), but she was killed. So he set out to bring down the nation that killed his child (didn't care who got hurt).
He does end up giving his title and wealth to Dantilian, because it is the only he can give it to his daughter (now Sherina). Dantilian intends to stand by Sherina's side and marry her eventually (hence why he needs standing to able to do that, since she is part of the Crown family), so as his wife she would be entitled to everything and their children would inherit thereafter. So they both win (Dantilian gets to be with Sherina and Asmodeous gets to indirectly hand his wealth and land to his daughter).
He also doesn't hesitate too much on handing the title over since he is also dying, I don't think he ever reveals that he was Hella's father to Sherina, since that chapter of her life has closed and he doesn't want to drag her down with unnecessary baggage.
Mind you this was a summary translated with Google. Unsure if the novel or story ever goes into details on why he didn't know he had a child or if he knew, but she was taken and had not been able to find her, who the mother was, etc.
How many chapters are there left before this series finishes? Can anyone give me some spoilers? What about that red eyes old man, he was some duke? Is (was) he Hella's father?
Indulge me
