I meant that: you said that they're finally meeting, but Sherina has already met Asmodeus, she is aware that Asmodeus exists (even if she doesn't know who he is exactly), and we the readers have already met Asmodeus. So I guess I was confused on your word choice of "finally meeting" someone that we (and Sherina) have already met.

If I remember it correctly, asmodeus has a wife who he loved very dearly and they were expecting. But the wife learned that the child was dead or wont live, something like that. She was devastated by this and I think she performed some dark magic stuff (or sold her soul to the demons, can't remember correctly) to revive her child (hella) but it didn't go well so both her and the child ended up dead. When asmodeus learned this, it was already too late so he buried his wife and child. But, he also didn't expect that his wife succeeded so the child he thought was dead actually ended up living (hella). When he discovered this, it was also too late hahahaha so he was like finding his daughter's whereabouts. I can't remember if he was able to learn that hella, the leader of silopia, was his daughter and just didn't approach her. Or if it was again, already too late when he learned that hella was his daughter, but isdead because of the magic tower. Can't remember between the two but one thing is for sure, he is avenging hella and he is not aware that sherina is actually hella
Finally she met her real father!!!
