Isekai Mao to Shokan Shojo no Dorei Majutsu

But not a huge amount more.

This a bit of a "Isekai" at its core ( main premise) and it's atleast amusingly used to help explain away the "Harem" portion of the Anime. There is the typically Ecchi fan service, and some of it is a little better disguised / worked into the plot than many similar shows, and some solid character growth between the protagonist and his "harem".

Overall it's enjoyable, a good watch for the Covid-Crisis of 2020, and a second season was announced, but it's not groundbreaking.

Its has a bit too much fan service for my taste, but if you can overlook that its surprising good. You actually get invested in some of the characters, for me the characters of Emile Bichelberger were surprising good. In episode four Emile Bichelberger is badly injured and about to be killed, after valiantly facing a fallen, when the demon lord arrive and puts his hand on Emile saying he was a hero and that he would take it from here, I was moved. It has its share of silliness, but not as much as you would expect and the ending is reasonable. The tropes used are well worn standard ones but the execution is very good so they seem fresh.

Animation - Everything from the character designs to the fight choreography, to each bounce of a titty clearly had a lot of thought put into it. The overall look of this show is very well done, and I applaud the animators, who clearly had a lot of fun doing their jobs.

Characters - I was expecting the cast to just be a bunch of cliches and was pleasantly surprised to find that everyone had unique personalities. The lead guy is actually quite likable.

Plot - All jokes aside, this show actually does have a plot. While its not that complex, and the overall runtime is most dedicated to fan service, fight scenes, and just straight-up comedy, there is some interesting stuff going on here. Its not brilliant but its fun and serves as a nice framework for all the jokes. This is not a show you are going to enjoy if you take it seriously.

Voices - The voice acting in this show is pretty good, the actors are clearly into their roles, and it makes the show fun to listen to as well as watch.

Deadpool could take a lesson or 2 from this show. Its so adult, and yet hilarious and a top notch anime all around. I was pretty surprised by it.

When compared to other isekai like Log Horizon, Sword Art online or Overlord, it's more similar to Overlord. A hardcore solo player wakes in the body of his completely overpowered character in a fantasy/mmorpg world. More or less following the Overlord formula, he now has to find out how the world works and ends up helping people along the way. Although it has its awkward and funny moments one might get tired of them. Also this is falls under the "ecchi" genre, so be prepared to busty girls, panties and innuendo
