[Edit]
Nana has been adapted into an anime series, directed by Morio Asaka and animated by the studio Madhouse. The first opening and third ending songs are sung by Anna Tsuchiya for the band Black Stones, and Olivia sings the second opening and first and second endings for the band Trapnest as Reira Serizawa. The first DVD release was on 2006-07-07. The anime series was intended to be equal to the manga and it was adapted until the 12th tankoubon to avoid original anime fillers. According to Junko Koseki (editor of Nana in Shueisha) and Masao Maruyama (president of Madhouse) a second season is probably going to be aired once the manga series is finished.
