Hana has nothing but she's hopeful. She's fifteen years old. She lives in a tiny apartment in a suburb of Tokyo with her young mother, a hostess at a local dive bar.

They have no money, no security. Then Kimiko appears.

Kimiko is older, a bright light in Hana's dark world. Together they set up Lemon, a bar that, despite its shabby setting and seedy clientele, becomes a haven for Hana.

Suddenly Hana has a job she loves, friends to share her days with, and the glittering promise of money. She feels like a normal girl. She feels invincible.
