This is not entirely correct information, because if you were careful, you could find a note that says that the hero’s FATHER is NOT the hero’s father, but a kind of OPIEKUN, custodian ?
(I don’t know this word in English 8 ((I think, HE was a close friend of the hero’s father and something apparently happened to the father because of which they had to take the boy and raise him like his own son, so I wouldn’t be surprised if a CULT is involved here) )
the real father has Kirlic roots and (sort of) was from the nobility (held a serious position) ... incl. she is not a mother and a friend is NOT a sister, butoooo (this is my guess) perhaps the QUEEN is the real mother of the hero and the runaway daughter is his sister (but these are my guesses)...
And the king, who came to the village, is not his father, but perhaps a usurper of the throne (and he may even be holding his father hostage O_O, I have a lot of imagination ^_^)....
And there are no scenes of Incest in fact, except for TIA + her father( but these are ORCS X_x if this is considered and possible in the NTR branch Dazan and his mother in the village)...
