"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! Being engaged isn't as wonderful as Hachi thought it would be. She has a trendy new apartment, but she's isolated from all her friends and Takumi is hardly ever home. When scandal hits hard, Trapnest (and her fiance) flee to Europe, and Hachi is left to watch Blast suffer in the scandal rags and tabloid shows."
