Man, I love this anime so much. It is so hilarious. This is just an extra episode OVA from the first season, and under any other circumstance, it wouldn't be anything special. But, because it's Konosuba, it had me in tears throughout. It's a very simple episode, where Kazuma puts on a magic choker that will kill him if his wish doesn't come true. And so, he has the rest of the crew do all sorts of lewd things to try and get it to come off. That's really all there is to it, but it's so hilarious. One of themost endearing things about this anime are the MC's total lack of morals. And it is on full display here.

I can't really say more than that. If you like Konosuba, you will love this episode.
