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!

One of the tabloids hounding Blast and Trapnest has photos that make it look like Reira and Ren are having an affair. With Nana and Ren’s engagement recently made public, the photos could spell doom for both bands. Takumi’s willing to do whatever it takes to save his band, but how will it affect Hachi and the happily ever after she’s still hoping for?
