Asuna Hoshizuki is beautiful, loudmouthed, and hits like a freight train. A jobless dropout, she doesn't have much of a life, but she has a loving mother and a family restaurant she helps out at. But after a run-in with a band of yakuza, she finds herself deep in debt to a crime family. With a net worth amounting to a few loose coins and some pocket lint, she's left with no choice but to work for the very men she's indebted to. But in the process, she learns about a secret underground world, a cyberpunk city hidden from sight. Now to pay off her debt, Asuna will have to use her incredible strength to help the Matsuba Clan seize control of the crime-ridden Undercity.
