Jirachi Masuda is Creep's friend from college who introduced the Masuda method to those in Purrloin's Creek City. Ever since Creep found the way to the real world, Masuda followed him out when the raichu in black and his family found a place to live when his parents died. Masuda gave Creep an egg that he found in the forest. The egg's mother was caught by a trainer, so he decided to have Creep take the egg and let Demon keep it company while he's working. When the egg hatched, out came a shiny charmander named Marshall.
