Nana (ナナ) is a Japanese manga series written and illustrated by Ai Yazawa. It was serialized in Cookie magazine from July 2000 until June 2009 when it went on indefinite hiatus, with almost all its chapters collected into 21 tankōbon volumes published by Shueisha. The series derives its title from the name of the two main characters, both of whom are called Nana. Nana Komatsu is a small town girl who goes to Tokyo to follow her boyfriend and college friends, with the hope of having her dream life. Nana Osaki was in a popular punk rock band in her hometown. She goes to Tokyo with the goal of making it big as a singer. The two Nanas meet on the train ride to the city. Later, they run into each other again when they happen to check out the same apartment, and the girls decide to become roommates. The series chronicles their friendship and their lives as each chases her dreams.Nana Osaki, on the other hand, is cool, confident and focused. She swaggers into town and proceeds to kick down the doors to Tokyo’s underground punk scene. She’s got a dream and won’t give up until she becomes Japan’s No. 1 rock’n’roll superstar. This is the story of two 20-year-old women who share the same name. Even though they come from completely different backgrounds, they somehow meet and become best friends. The world of Nana is a world exploding with sex, music, fashion, gossip and all-night parties.
