Firstly, despite the name...no, it's not horny, and is in fact quite wholesome.

I'm only halfway in, but so far it's one of the better comedy animes I've see. In my opinion, comedy isn't one of anime's strong suits, and only a few have seriously amused me. Those being things like KonoSuba and Cautious Hero: The Hero Is Overpowered but Overly Cautious.

This has been funny so far, though. Basically, an antisocial sorcerer who lives alone in the woods happens to rescue a, well, as the title says, disgraced noble lady. Due to his antisocial nature, he's known to the nearby town as the Demon Lord, and he often cackles manically over his totally evil plans to...try to make this lady happy by "corrupting" her to enjoy life.

That's the sales pitch. If you're curious, check it out.

By the way, two other animes I'd recommend, but won't go into full detail about in this post: Synduality Noir and Dead Mount Death Play.
