With Saitama no rappa 2 (AKA 8000 Miles 2 – Girls Rapper), Yu Irie tells the story of amateur girl rappers who dream of a small big-time. The film opens with Saitama 1 B-boys, Ikku and Tom coming to town. They run into young Ayoma (Maho Yamada), inspiring her to gather her girlfriends and work up their rap routine.

Sakura is a moody teenage girl who lives close to the US military base in the city of Yamato, Japan. She is struggling everyday to become a rapper like the American rappers she admires, but always gets stage fright when she sings in front of an audience. One day, her mother's American soldier boyfriend's daughter REI comes from California to visit her family.
