Nana, Vol. 17 by Ai Yazawa

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!

Ever since she got engaged to Takumi and moved out of apartment 707, Hachi has felt like she's slipping out of Nana's life. When the tabloids start digging up Nana's troubled family history, Hachi tries to step in and take care of things. But the price for bringing down Blast keeps going up. Will Hachi's good intentions just make things worse?!
