The dragon is kind of like King, from One Punch Man, because people think he's powerful when he's a wimp. And Lingzi (Reiko) is kind of like Saitama, but subject to the mind warping field and also believes the dragon is powerful (and evil). So, you might imagine some of the antics that follow. It's not something you can take seriously, because real people have reasons for their beliefs, but if you let it go, it's pretty funny. I said "antics" because nothing in the plot feels central to the plot. It's sort of slice-of-life-ish in that regard.
The animation is simple. Don't expect any breathtaking sakuga. It looks low cost, with limited movement. The characters look nice enough though. Somehow, they make it work, without looking bad.
I have no qualms with the voice acting. Dragon has a soothing avuncular voice, and Lingzi has a cute but dauntless voice which fit their characters.
The ED is a total banger. It's no exaggeration to say that it possibly kept me watching the show. I often skip EDs after hearing them a few times, but not this one. I rewind and watch/listen to it several times per episode. The OP is also good. Note that the art style is much simpler but more animated in the OP and ED than the show.
It's short, so if you consider that it's less than three hours, I'd say it's worth the watch.
