But now, a great evil threatens harmony in this great land. Far to the West, in India, someone is attempting to resurrect the youkai lord Gyumaoh by mixing human science with youkai magic. This forbidden practice has created a Minus Wave of negative energy that is spreading across Shangri-la, poisoning the souls of the youkai and turning them into mindless monsters. The only hope lies in four legendary heroes:

Genjyo Sanzo, a high priest with low morals.
Son Goku, the hungry and mischievous Monkey King, just released from 500 years imprisonment.
Sha Gojyo, a water sprite with an addiction for good smokes and bad women.
Cho Hakkai, the legendary demon slayer, and his transforming dragon Hakuryu.

To save Shangri-la, these unlikely companions, united by fate, must travel together ... INTO THE WEST!

Saiyuki Vol. 1

Having been assigned by the human elders the mission of stopping a mystical plague that has afflicted the Youkai with madness, Genjyo Sanzo assembles his team of Youkai warriors, desperately hoping that the disease will not affect them. He sets up qualifying tests that will help him determine the loyalty and worth of Cho Hakkai, Son Goku and Sha Gojyo. The team then journeys west to rid the land of madness.

Saiyuki Vol. 2

Continuing their journey west and leaving a trail of dead Youkai in their wake, Genjyo Sanzo and company come upon a young woman who has quite a tale to tell. She recounts the story of her long lost lover, a Youkai who succumbed to the madness and for whom she waits faithfully to return. As the story continues, Gojyo has an epiphany that just might be a clue about the source of evil that has been unleashed on the land. In this next volume of Saiyuki, the fantasy adventure becomes a family affair!

Saiyuki Vol. 3

In the midst of battle with the cursed human, Rikudo impales Sanzo while he tries to protect Goku. In the melee, Goku's Youkai power limiter, the device that keeps his Youkai madness from taking over his soul, shatters, sending Goku into a violent rampage that yields for neither friend nor foe. It may take divine intervention to bring the ancient warrior back to his senses!

Saiyuki Vol. 4

The mysterious fortune-teller Chin Yisou takes great pleasure in pushing Hakkai's psychological boundaries, and Hakkai is frightened to find his bloody past nipping at his heels. When Chin Yisou starts targeting Sanzo and the others, our heroes find themselves not only fighting against him ... but against each other!

Saiyuki Vol. 5

Three years before our story began an unlikely party formed. The story of how Sanzo, Goku, Gojyo, and Hakkai met is revealed at last -- violence drew them close, but something far more powerful kept them together. Now with bonds forged in insecurity and despair, our party is trapped in an undergound youkai den with a malicious female demon. Her interest lies with Sanzo, but her strength lies with her poison ... and her ability to make it linger.

Saiyuki Vol. 6

Sanzo's life is on the line. He is stranded in the desert with no way out as Goku desperately searches for a way to save Sanzo from the poison coursing through his veins. An unlikely run-in with Kougaiji offers a possible cure. If Kougaiji is defeated, Sanzo may live. But the sacrifice of Goku's sanity may be too high a price to pay. After all, if Goku saves Sanzo, who will save Goku?

Saiyuki Vol. 7

A set of twins catches our heroes by surprise and trap Goku and Hakkai in their magical gourd. Sanzo and Gojyo set off on a journey to find the twins and free their friends and discover that the twins are working for a mysterious figure who is due for some punishment. Will their justice be swift enough or will they have to swallow a bitter pill?
