Konzen Douji is Genjo Sanzo's previous incarnation.
Kanzeon Bosatsu’s nephew. His status as a god was high, but his job consisted mainly of paging through documents, and the boredom was killing him. He’s a typical young master and doesn’t know what hard work is; although he’s the iron fist in a velvet glove and has a huge attitude, he has no strength or patience. He’s pure only so far as he has no worldly knowledge. He met Goku, and was influenced by Tenpou and Kenren as well, and defeated his previous self in order to protect that which was important to him, gaining the determination to face up to a huge power.
He has long, fine golden hair, and long-lashed drooping eyes. His appearance resembles Genjo Sanzo somehow. Source: Saiyuki.wikia
