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.

Toki Mishiba, Nobuto Nakajyo, and Kazuo Saitoh are hired to play the Biz Game, a game much like capture the flag, only with company secrets and insane amounts of money involved. At first they think it's a crazy but fun way to get some money, but as the game goes on, they hear stories about mysterious deaths on the news, and recognize the victims as members of the teams they've beaten in the game. When one of the losers of a game dies right in front of them, they realize what is really at stake - their very lives!

Note: Bus Gamer was originally published in shoujo magazine Stencil, but was later re-drawn and re-published in shounen magazine Comic REX. Both times it was axed after the magazine went under. This is the Comic REX version.

500 years before the story of Saiyuki, a heretic child with golden eyes is brought into Heaven. He is given into the reluctant care of a minor deity named Konzen, the nephew of the Merciful Goddess Kanzeon Bosatsu. Konzen eventually gives the child the name "Goku". Goku becomes friends with two other minor gods, Marshal Tenpou and General Kenren of the Western Army of Heaven. He also meets a strange little boy who seems to be his own age, the War Prince Nataku. Although Goku is happy in his new home, Heaven is not kind to heretics. There are those who would use Nataku and Goku as tools in an attempt to seize the throne of Heaven, and Konzen, Tenpou, and Kenren may not be able to save them.
