The gunslinger of Grand Order, Billy The Kid, has a very carefree attitude. While having no preference on how he fights, Billy is no stranger to fighting dirty in the heat of combat, probably stemming from his life as an outlaw. His real name is William Henry McCarty Junior. A representative outlaw from the American Wild West, even in modern times his popularity is extremely high. From the fact that one of his few remaining pictures was put for a price of two hundred million yen in an auction, one can perceive said popularity. His father is unknown, but it seems that he received a higher education from his mother and, considering he was a Western outlaw, he left behind some skillfully written letters.
