Dairuz, a monk with a mechanical body was on board of the 999. His rang his bell throughout, and the sound waves were powerful enough to damage the train and all of Tetsuro's teeth. The Conductor took the train to the Medical Treatment Asteroid for an overhaul as a result. Maetel and Tetsuro met Maria, who brought her boyfriend Mikhail for gunshot treatment from their homeworld, the crime-ridden Asteroid 33. The operation was successful, but Mikhail was losing his will to live. Dairuz tried to save him with prayers, but it was Tetsuro who gave Mikhail hope to live on. Despaired, the Dairuz smashed his bell, and sacrificed part of his body so that Tetsuro's teeth could be fixed. In parting, Dairuz, who was now attached to a rock to sustain his body, told Tetsuro he had to remeditate to change his way of salvation. (thetvdb.com)
