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's band Blast is taking off in a big way—from sold-out club dates to a record label waving a contract at them. But the Trapnest menace still lurks, stealing away everything she cares for. Trapnest took her boyfriend, and even though Ren is back in her life, his band still comes first. And now her trusty sidekick Hachi is being lured away by Trapnest bassist Takumi. But this time, Nana won't give up without a fight!
