Pokemon Adventures: Black 2 and White 2 Vol. 1 (manga)

Colress, the new leader of Team Plasma, is attacking the Unova region. His machines control Pokémon, wielding their powers for evil instead of good. Fortunately, a way to jam the signals is stored on a memory card. But who has the card…? A girl at the Pokémon Trainers’ School! Maybe that’s why our hero is such a flirt—he’s just doing his job gathering intel. But he’d better stop playing the field and find that card fast before someone beats him to it!
