131 chapters later we got progress between the ML AND FL. And 131 chapters later we have no clue who kill her family? What is the story plot?

SPOILERS AHEAD
So the Church and the current King are the baddies in this one, they have a Saint who is able to brainwash people and has been indoctrinated to do so (in the end Lippe comforts her as she was groomed into being a weapon), Lippe's ability is to 'purify' things with her singing.
I think it was the King who order the murder of her family, but the Church were the ones who were behind it, the King is just a really greedy bastard
stay safe and healthy asami-sensei. this is oone of the nicest hiatus announcement ive ever read.
