I recently decided to pick it up again, but I don't remember the chapter Last things I remember is about Liza being invited into some king of a knight order with the offer of releasing her from slavery. She refused though, and then the city was attacked by demons That's about it, hoping for your help)
Probably around chapter 12-13.. The royal capital got attacked by at that time... I think its before Liza & other conferred knighthood
