Yu yu hakusho

This is canon. The first part (Two Shots), took place a year before Kurama and Hiei met Yusuke and Kuwabara. Meanwhile, the second part (All or Nothing), takes place after the end of the main series.

Some of the original voice casts didn't return for these shorts. It was noticeable, especially for Yusuke, Hiei, Keiko and Kuwabara's sister.

Overall, amazing animation quality and great improvement in fight choreos. Love the action and thrilling aspect of this short/special episode. Appreciate some of the cameos, even if it's only a few seconds.

Something the long-term fans would appreciate. Recommended.
