Yu Yu Hakusho

Yu Yu Hakusho:

Yu Yu Hakusho (Ghost Files of Ghost Fighter) in english translation is one of the long running anime of 90s to 2000s, along with  Dragon Ball and other anime series that were from the old days. It is a full blown anime action venturing the spirit world like Bleach and Death Note with a totally different vibe on it.

Spirit or Ghost Busters were so popular back then and I believe that was the inspiration for this series. It tackles so many supernatural ideas. If you are a big fan of action anime and looking for some old school stuff this is one of the best to recommend starting with.

Just a side not Yu Yu Hakusho is written by Yoshihiro Togashi which is also the writer of Hunter X Hunter.
