After a string of epic romantic failures, Nana Komatsu is ready to take control of her life and get a clean start in the big city. After prioritizing her musical ambitions over love, Nana Osaki is ready to stomp her way to the top of Tokyo's punk scene. With determination in their hearts and dreams in their eyes, the two Nanas are ready to take the world by storm!

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.

Anxious to get into a Tokyo groove, both women are on the prowl for a funky and cheap place to live. But inexpensive apartments in Japan's capital city are hard to find. Thank goodness each Nana has a clique of cool friends willing to help out. Too bad these friends are a little eccentric!
