Saiyuki, known as Gensōmaden Saiyūki (幻想魔伝最遊記, “Romanticized Tale of a Journey to the Extreme”) in Japan, is a popular manga series created by Kazuya Minekura and loosely based on the famous Chinese novel Journey to the West (Xī Yóu Jì). It has been turned into an anime series by Studio Pierrot as well.
Gensomaden Saiyuki deals with the fortunes of four fighters – the monk Genjyo Sanzo (transliterated Genjo in the anime and Singapore English manga), the monkey deity Son Goku, the half-demon Sha Gojyo (sometimes spelled Gojou), and the demon Cho Hakkai, who have been dispatched by the Sanbutsushin (The Three Aspects of the Buddha) to India to investigate the reasons behind the recent insanity among the demons. Demons, who have formerly coexisted peacefully with humans in Shangri-La, are going berserk and turning against them.
The manga is published in English in North America by Tokyopop, and in Singapore it is published in English by Chuang Yi. The original anime series is produced in North America by ADV Films. Sequels Saiyuki Reload and Saiyuki Reload Gunlock are licensed by Geneon in North America. The prequel manga, Saiyuki Gaiden – which takes place 500 years before the first series – is currently published in the quarterly Japanese manga magazine Zero Sum WARD.
