Landing on the rooftops, Daki realizes he is the one she had struck. Zenitsu menacingly demands she apologize to the young girl she had hurt, claiming that the girls who helped her aren't her belongings. Daki refuses to hear his lecture and claims that in this city, women are merchandise; they are only here to be sold, bought and destroyed. Zenitsu tells her not to push her pain onto others; hearing this, Daki claims he is wrong and begins to speak with her and Gyutaro's voices together.

As one, they state they hurt others and benefit from their debts, because they cannot make up for their own misfortune unless they collect it from the blessed.
