The action moves from the Saitama Prefecture to Gunma in this sequel to Yu Irie's breakout hit that proves girls can rhyme as well as guys. Back in high school, Ayumu (Maho Yamada) was a member of B-Hack, an all-girl hip-hop troupe. Now, at 27, Ayumu's rhyming skills don't pay the bills, so she earns her living making konjack in a factory owned by her family. But when Ikku and Tom show up seeking to pay their respects to a deceased Gunma DJ, Ayumu begins to wonder if she gave up on her dream too early. Before long Ayumu has tracked down her old band-mates Mittsu (Sakura Ando), Mamie (Kumiko Masuda), and Beyonce (Fumi Sakurai), and the rhymes are flowing smoother than ever before. Discouraged at every turn by the very people who said they'd always be there to support them, the girls determine that their only hope for escaping a life of sheer boredom is to keep on rapping with everything they've got.
