Man, I disliked the magic academy arc, but little did I know the price to pay for moving on to a new arc was leaving Rina behind. She made the school arc bearable to me, but I guess we won't be seeing her again for a while; gonna miss her for sure. Melki is effectively taking her place in his party.
I was concerned about how the "freeing the child slaves and indentured prostitutes" quest wasn't going well, but with this things should be a bit fine for a while, few are going to go up against someone high up like Irene. But I'm not sure how they didn't worry about how those who were freed will just be eventually replaced with new slaves, so short of abolishing slavery as an institution and industry this quest is just a temporary solution at best.
