First things first. My insane and totally deranged MC never sent his daughters to academy. NOT minding the costs, but for the keen understanding of what an utter waste of time and other resources that academy is for everyone - especially for students.I'm sure they have enough cavaliers at academy where they are studying I understand this a harem porn game, but assuming that all girls in the world are attracted to MC is a bit egocentric
The whole school-system of Ikaanos is just a sorry excuse for parents who can't or don't even wish to teach their kids themselves. Look what good academy did for Averil, as an example, see what mushrooms vacant-minded emkids eat in their precious dorms and feel the shame the whole academic society should about the effing thing.
Egocentric you say? There is no room for altruistic benefactors in a game where most everything worth doing needs your MC to do it or at the very least take decisive part in it. Why, you can't even send a trusted slave to sell some merchandise or catch a fish to feed your hungry house. You need yourself to fish, hunt, kill and ravage to get it done or forget it. It is a post-apocalyptic world and there are basically only two things coming for nice selfless masters; bankrupt and death. (Read fx. what Lovisa tells about "Master Roberts" and see what I mean, if you like. I have done that and learned a thing or two, I imagine)
