Throughout the course of KonoSuba's first season, it became apparent that its primary appeal to many people is arguably its use of an over-the-top and well-timed form of comedic humor. This OVA episode is simply an extension of that level of humor that many of us come to love and appreciate.

You can consider this episode more of a stand-alone episode - in terms of plot, it is not connected to any part of KonoSuba's first season. To summarize quickly, our four favorite wanderers - Megumin, Aqua, Darkness, and Kazuma - enter Wiz's shop one day, where we meet Yunyun, Megumin's self-proclaimed rival. As they bicker among each other, Kazuma puts on a magical device that can grant any wish. If the wish isn't granted within a four day period, the user dies. Since Kazuma doesn't wish for anything (or so he thinks), he uses the next four days to make Megumin, Aqua, Darkness, Yunyun, and Wiz to do whatever he wishes. Hilarity ensues.

Simply put, this was a nice and fun OVA to watch. It's difficult to critically analyze OVAs since they tend to be short (only 20 minutes long) and don't follow the main story, so I've spared you the trouble. But in terms of the script itself, the writing is highly consistent with the execution of that of the first season. The humor hits you just at the right moment, and the writers of this OVA have delivered a surplus of it, that's for sure.
So, should you watch this? Well, for one, if you're expecting something really deep or meaningful, you have come to the wrong place. Or perhaps you think the characters will be more tolerable despite the fact that you found them bland and irritable during the first season - well, unfortunately, they're exactly the same, so I would not recommend watching this OVA if you hold that opinion. On the other hand, if you liked how KonoSuba's comedy played out during the first season, you'll probably like this too. And, finally, it should be noted that there is some combination of fan service, crude humor, and lewd humor present - and, at times it was on the level of what we witnessed in the infamous Season 1 Episode 9 ("God's Blessing on this Wonderful Shop!"). So if you found yourself cringing throughout Episode 9, maybe this also isn't for you.
All in all, this was a humorous time-killer. Fortunately, in case you haven't heard, there is a second season in the works right now. But for now, this will have to do until it's released.
(Side note: As with all other reviews that I write for OVAs, overall rating reflects enjoyment only.)
