Volume 2 of Pokemon Black and White contains chapter 5 to 7.
It is rated A for all ages. (although it does contain some violence)
Like all manga, this book is read right to left. Confusing at first but easy to get used to.
The second volume focuses on White, the female trainer. Unlike Black (the male trainer who strives to be the Pokemon master), she runs a Pokemon talent agency. White needs a male and female Tepig for a shoot but she only brought a female. Luckily she runs into Black who owns a male Tepig. And thus, Black and White meet! But of course, things don't always go smoothly.
We meet new Pokemon and the bad guys of the series, Team Plasma! Team Plasma's goal is to set Pokemon free! (which I personally agree with, it's not nice to keep your Pokemon locked up in a small ball and then make them battle each other)
If you own volume 1, you will notice on that cover is a man with green hair. We are introduced to him in volume 2 (and if you have played the games, you will know a lot more about him)
Like the first volume, it is wider than a regular manga book but a lot thinner so it doesn't take up much space. It is also the same quality as the first volume.
If you have read the previous volume and enjoyed it, you might as well read this one too as it is just as good! Although it is possible to pick it up without reading volume 1, I would still recommend reading volume 1 first.
