I think this is the first time that Canon Creative Park has actually made a papercraft based on anime / manga. Can you remember any that I might have missed?
To make the story short, Saiyuki revolves around four anti-heroes: a priest (Genjyo Sanzo), a demon slayer (Cho Hakkai), a half demon (Sha Gojyo), and the monkey king - Son Goku. They travel to India to stop the resurrection of the demon king, Gyumaoh. And on their way, they battle assassins, bad weather, and other villains intent on stopping them from achieving their goal.
