This is a goofy, loud, in your face show of shorts with almost nothing to do with Fist of the North Star properly. It's slapstick humor with a bunch of silly characters that's fun to watch, with zero depth, and you can finish it all in a short while since it's all out now. It would have been much better if there was some cohesive storyline here or some conclusion that felt important, but nah - it's just watch 3 minutes of whatever, laugh at it and move on. The animation is fine for what this is and conveys the tone well enough. The voice acting ispretty good! There's emotion here, but you get the idea pretty fast about the entire show from a few lines in the first two episodes.

There's really not much to say beyond it's here for a good time, not a long time. Just watch this all in one go if you're going to at all. It spoils nothing for the main series and has nothing else beyond what it shows.
