Debt Collection Rhapsody is the eighteenth chapter of Hinamatsuri manga series.
Plot[]
Hina goes with Sabu to collect money from a factory owner that took out a loan from the Yakuza. The owner skillfully avoids repaying his debt by assuring Sabu that he's going to have the money after his next shipment is ready, and that Sabu is wrong to press him so hard for the repayment.
While Nitta scolds Sabu for being a pushover, Hina accidently returns to the factory. The owner and his employees mistakenly think that she's there to push them to repay again, and her stoic attitude and vague answers to their questions terrify them. The owner personally takes the money he owed to Nitta after he finishes the pending job and scolds Nitta for sending a child to collect a debt. Soon, Nitta gains a reputation for being a ruthless moneylender.
