Pokemon Advanced Generation - Nov 21, 2002 to Sep 14, 2006

After participating in the Johto League, Satoshi decides to begin anew in yet another journey; this time by himself and Pikachu, in the land of Houen. Though he isn't alone for long, as 10-year-old Haruka (whom dislikes Pokemon, but just wants to come along to see the world) travels with him after Pikachu destroys her bicycle. Satoshi also meets up with his old companion, Takeshi, and Haruka's younger brother, Masato. Together, they travel along in Houen, battling Gym Leaders, entering contests, and other events on the way to the Houen League. (Source: ANN, edited)
