More commonly known as Methuselah, Rain is 624 years old. His immortality makes him famous, and he is the subject of numerous bounties. The cause of Rain's immortality is a mysterious man who appears in flashbacks early in the series. Rain is described as a "nice screw-up" and is one of the funniest characters. He falls in love with Machika as the story moves along. Tending to stay away from violence, he doesn't try to stay close to others because he fears their deaths. Rain in the flashbacks was shot and killed by Yuca and then "reborn" by him after Yuca fed him Freya's, an infected subject, flesh and blood. Rain is the opposite of Yuca in many ways, and has told him he will never view life the way Yuca does. Rain has all the powers of an angel, but none of the drawbacks, and is considered a "perfect immortal." He has a relaxed, slightly off beat personality.
