Wu Cheng'en
The series is an adaptation of the 16th-century Chinese novel "Journey to the West" by Wu Cheng'en, transplanting the events to a far-future science fiction setting. Tang Sanzang becomes Yakumo, a girl tasked with reviving the human race rather than retrieving sacred scriptures. Sha Wujing becomes Sago, Zhu Bajie becomes Kutal (who transforms into a lion), and Sun Wukong becomes Mushra (retaining the character's golden headband and telescoping staff).
