I only recommend this series if you're a fan of isekai and also (strangely) to some degree Batman. I think that pretty much somes up what this series is about. An iisekai fantasy with a clearly overpowered, dark, and edgey protagonist who always wins. If I were to compare it to other anime. I'd say it's konosuba meets one punch man and make it at least 1000% more edgelord and cringe. The only thing I personally don't like about it are the harem and ecchi aspects. I've long since out grown such things but others might see it as a selling point.
