It's actually passable to some degree at the premise. Sure the gender-bending isn't anything new, but I'd be interested in seeing him/her dodging sexual encounters in a fantasy world. That'd be something.
Unfortunately, this sperg lord is the worst fucking thing. I hate this dude so much. It's like I'm watching an ecchi anime from the perspective of one of the harem girls. It's really vile. I could nitpick the specifics on why he's a horrible, disgusting, unlikable piece of garbage, but I hope that it speaks for itself.
