Yu Yu Hakusho: Fight for the Netherworld (1994) on Netflix

Plot summary

A tsunami makes the River Styx overflow, flooding the Spirit World, and Koenma takes the disaster as the sign of an extremely powerful enemy. He hands Botan a mysterious item to carry to Spirit Detective Yusuke Urameshi, but she is badly hurt on the way and hides it. Yusuke finds Botan and her friend Hinageshi wounded and has them taken to Genkai's temple, where Kurama and Hiei join him. The storm came from the Netherworld, a realm Lord Enma drove into cold space long ago. To restore the flooded Spirit World, Yusuke and his friends follow Hinageshi's guidance to five places on Earth that hold a large amount of spiritual energy. Yakumo, the ruler of the Netherworld, and his three demon gods want the same energy to win their realm a place on Earth.
