I was today years old when I learned the word "Isekai." Not sure how it's passed me by until now; in hindsight I've watched plenty of anime that fits squarely into the category, including favorites like Sword Art Online and Kyo Kara Maoh!. And Sword Art points to an increasingly common tack for the isekai genre: The other world that the protagonist gets stuck in is a video game.
Such is the case with Demon Lord, Retry, which has a strong Overlord whiff to it. I had multiple feelings of deja vu while watching this, particularly by way of Overlord's first season. But while the whiffs are there, the actual tones between the two series are quite opposite. Demon Lord, Retry is lighthearted and frivolous, lacking any kind of real plot, and seems to exist mostly so our insert protagonist can encounter a ton of women who become desperately attached to him.
It's surface-level entertaining as a mindless piece of television to while away half hour chunks of time. But it's not the sort of entertaining that will linger in your mind; if you start skipping this in your anime rotation, it'll be hard to remember to pick it back up. (Which is why it took me, like, three months to watch this 12ep series, lol.)
Episode 12 ends with an optimistic 'To be Continued,' but at this point I'd be shocked any more is made. Even if the series was paused to allow the original light novels to provide more content, this just isn't good enough that a studio is likely to want to sink more money into. That said, despite my poor scores, if they did continue it I'd be curious to check more episodes out—and probably regret it—because there's just enough groundwork laid here that I'd want to see what becomes of it.
