Diamond & Pearl (Japanese: 第七章 ダイヤモンド ・ パール編The Seventh Chapter: Diamond and Pearl) is the seventh chapter of the Pokémon Adventuresmanga, consisting of nine volumes. It is the third longest completed chapter of the series. In North America, this chapter is grouped with the Platinum chapter as the eleven-volume Pokémon Adventures Diamond, Pearl, and Platinum, as Pokémon Platinum Version had been released internationally by the time these two chapters were released internationally.
The chapter follows the adventures of Diamond, Pearl, and Lady Platinum Berlitz as they travel through Sinnoh towards Mt. Coronet. The aim of the journey is for Platinum to fulfill a family tradition by using a material from the mountain's summit to create an accessory bearing the Berlitz family crest. However, a misunderstanding leads her bodyguards to be switched with Diamond and Pearl, who think they are in a reality TV show with Platinum as a tour guide.
The journey is made difficult as the group get detoured by Team Galactic numerous times which in turn causes Team Galactic to get irritated by them. During their travels, Diamond and Pearl frequently practice their manzai comedy routine while Platinum decides to test her skills by challenging Gym Leaders and Contests.
