The King seems like the worst kind of douchebag: A 'bicycle rider' - kicking those below him, while bowing like a spineless worm to those he can not quiet reach with his feet. Really hope we can influence that with choices later...
Imo it would be nice if he showed some strength and cunning before any potential 'magical' interference happens - outside of 'ordinary school boy gone chosen one'-settings, it's always cooler if a harem is 'earned' in some way, rather than being just granted by some supernatural mind bending force / godlike intervention and stuff like this. Else it always has that bitter taste of being just an impotent power-fantasy.
Still an interesting setting and much potential for the story to grow nicely. Neat models too, especially dig the unique and fitting look of the king. The (planned) tags will likely also 'speak' to enough people to get some interest going.
Welcome and good luck Machinist!
