Now I'm a Demon Lord! Happily Ever After with Monster Girls in My Dungeon · review
It's generic, but in a good way. If you are a fan of the typical 2019 isekai story of an OP protagonist with a RPG menu building a harem, then this is a great read to scratch that itch. It's got everything from generic bad guys with the typical 1-D bad guy personality - to dragons taking human form as a girl. So far the protagonist remains top dog saving girls left and right. If you are into this type of story, then I would recommend giving this manga a read. I do see potential for this manga to go more in-depth when it comes to whatit means to be a hero and the various shades of grey. But, I don't think this is where it's going, and there is nothing wrong with that.
If you took a break from anime/manga for a while and just came back. This manga is also a good one to gauge the current trends.
