This was a phenomenal little set of mini episodes. There isn't much to say about each one, but the humor was on point, and the story beats were pretty interesting. It felt like Yusuke's Bizarre Adventure, which was something I enjoyed. If there was more to this I prolly would give it a 10/10, but it's size really limits the storytelling. The voice actors REALLY went in, more so than many episodes in the series.
Things like this really are quite interesting to me, so potentially I'm biased, but it makes me want more Yu Yu Hakusho content, which really is far to little considering how success the franchise was, and continues to remain.
