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!

Ren’s drug use is spiraling out of control and he doesn’t want to drag Trapnest down with him. Neither Takumi nor Reira are willing to let Ren quit the band, and both do their best to give him the time he needs to get it together. But Ren isn’t sure this is something he can handle on his own. Will he turn to Nana for help, or will their strained relationship make him try to face his demons alone?
