The series comes from the manga by Yoshihiro Togashi which ran from 1990 to 1994, culminating in nineteen volumes.
The series has now been added to the Tubi TV streaming service in full with the 112 episode run available in its original Japanese language with English subtitles here.
Funimation’s expanding the reach of one of its earliest properties that helped it to get into the anime distribution game more with Yu Yu Hakusho.
Togashi’s also well known for his work on the Hunter X Hunter series that he created as well as the short series Level E. The anime TV series originally aired back in 1992 to 1997 with Studio Pierrot animating it.
