I have a feeling Vivian isn't really his biological daughter. What if his sister had a secret child with a demon king or something (or soemone poweful) then had to die or something then vivi had to be raised by her uncle and his wife. You know what i mean? Cuz there's gotta be more from what the father said about
"Especially if you find out who killed your mother/parent" something lik this when vivi was looking at the forest oit the window before she slept. Like my gosh a lot of theories in my mind
The demon king is a woman, they already showed her in the chapter talking about the power of her heart (didn't show her face, but you could tell it was a woman with long pink hair)
