I'm going to start my blog with one of my favourite anime/manga. It's 'Nana' . We can say that 'Nana' is a josei manga, what means it's focused to women and has elements more mature than the usual school girl stories.
The author of 'Nana' is Ai Yazawa, that it's also one of my favourite mangaka (comic artist). Other mangas of this author is, for example, 'Paradise Kiss', another manga/anime worth to see =^^=. 'Nana' is developed around the world of the music and 'Paradise kiss', around the fashion world.
And the story? Well, the plot is simple... at first. Two girls meet in the train in their way to Tokio. Two different girls, with different lives and styles that share the name. One is Nana Osaki: independent, mature, singer of a punk-rock group (Black Stones/BLAST), hard, but only in the outside. And Nana Komatsu: childish, insecure, a bit selfish and dependent. Then, we'll know a lot of other characters as their friends, their loved ones, their enemies, and how hard the life can be sometimes.
The manga has an anime serie and 2 'Live action' movies.

And one of the great points that 'Nana' has: Its B.S.O. As I told before, it's around the music world, and the anime has awesome songs like these. Enjoy ^^!
