Saiyuki Reload -Zeroin- contains episodes 1-13 of the anime directed by Misato Takada and is the sequel to Saiyuki Reload Blast. Hundreds of years ago, the war god Nataku Taishi defeated the monstrous Gyumaoh in battle, imprisoning the foul creature in Houtou Castle. For many years tranquility ruled the land, with humans and the yokai-the spirits of the land-living in peaceful coexistence... until misguided attempts to resurrect Gyumaoh unleashed a wave of negative energy, driving the yokai berserk! To save humanity, and to prevent Gyumaoh from rising once more, the goddess Kanzeon Bosatsu sends the legendary team of Son Goku, Genjo Sanzo, Sha Gojyo, and Cho Hakkai into the west! Their mission: stop the slaughter, discover who is responsible, and ensure that Gyumaoh remains locked away forever. Now four heroes must find a way to work with a mysterious group of potential allies, as the epic saga continues!
