In Lust Harem you play as a novice wizard trying to make his way up the ladder, achieve independence from his family and most importantly, score girls. Struggling with tuition fees, being overworked for little to no pay and being average in magics you have a lot to work with. Fortunately things take a turn for the better when you manage to capture a succubus and use her power for your benefit.

Prank your guildmates, date girls, cheat on them, get them pregnant, take part in the school life, practice demonology, necromancy, participate in cults and enjoy the dark comedy.
