A chance meeting on a train to Tokyo sends two girls named Nana on a collision course with destiny!
Nana "Hachi" Komatsu hopes that moving to Tokyo will help her make a clean start and leave her capricious love life behind her. Nana Osaki, who arrives in the city at the same time, has plans to score big in the world of rock'n'roll. Although these two young women come from different backgrounds, they quickly become best friends in a whirlwind world of sex, music, fashion, gossip and all-night parties!
Nana K. is going home—for an awesome Trapnest concert! She drags Nana O. along, convinced that somehow Ren will sense his ex-flame in the audience. But life is never that easy, and Nana O. isn't sure if she even wants Ren back. As for Nana K., is she prepared for Trapnest to come down off the stage and into her life, or will her fan-girl attitude land her in a heap of trouble?
