TLDR Solid concept which disappointsi execution on occasion, however the characters are fun and the comedy is good. First off this show does nothing new. However it focuses on the lonliness of power and the value of friendship. This gives it a central theme which, if it clicks for you, will probably carry you through the show. It's a well structured plot with arcs, although the transition to the last arc is a bit of a leap out of nowhere. The main character is your standard overpowered demon lord, but he has a code and a moral compass which help give him some identity. The two mainfemale characters also have their own identities and development, even if they get washed out towards the end in favour of turning them into damsels in distress.

There is one major criticism I have. The payoff of secrets is, basically, non-existent. A big deal is made about how he's keeping his previous life a secret at all costs, but it doesn't really have any major weight to it. There are certain plot elements which I can only imagine get resolved in the source material because despite their importance there's no payoff here.

If you're looking for something in this subgenre to kill time, that's reasonably entertaining, this is worth watching. Beyond that though I wouldn't recommend this for those who aren't already fans.
