As announced for this year, the classic anime Yu Yu Hakusho will return with a special OVA that will tell a side story, "Two Shots," where Kurama and Hiei meet as part of the "Sink or Swim" chapter of the manga, where the "Spirit World" was invaded by terrorists.
Check out the promotional image for the new Yu Yu Hakusho anime:

Created by author Yoshihiro Togashi (Hunter x Hunter), the saga tells the story of Yusuke Urameshi , a troubled teenager whose life is thrown into disarray after being hit by a car while trying to save a child's life.
The manga was published by Shonen Jump from 1990 to July 1994. It has 19 volumes and was licensed to several countries, including Brazil, where it was published by JBC in two different versions. The manga was adapted into an anime series by Studio Pierrot, which premiered in October 1992 and consisted of 112 episodes. In Brazil, the series aired on the now-defunct Rede Manchete television network.
