The story takes place right after the end of BW. It stars Arata (アラタ), a young boy who's not quite old enough to be a Pokemon Trainer. In this first chapter, Arata meets Cheren and gets him to help him protect a Keldeo he had befriended. Along the way, a duo of Plasma-Dan grunts who are unaware that their organization's been disbanded try to steal Keldeo! The two are eventually saved by Hiro (ヒロ), Cheren's friend who defeated the Plasma-Dan not too long ago.
The chapter ends with a time skip to two years later. A noticeably older Arata gets his starter pokemon and sets out on a new journey.
A little bit remind me of Kaito Pokemon 7! BTW nice drawing of Bianca and Homika. I wonder why Cheren didn't get the change as well.
So..... What the connection between New Bianca and Old Cheren and any other Protagonist. A little twist maybe?
