You seem to read her character wrong. While it's true, she is working in the brothel for money, but unlike typical whores, she is in her own, she even somehow convinced the council to give her S Rank Prostitute status. She picks her clients herself and also decides what she does. Usually she only does services, but no penetration. Even the council member can't fuck her without her permission as we saw in this update and it was the first time that she let someone fuck her, but only under the condition that he had to transform himself into Kirito and it was also an one time thing. To conclude, she is everything, but a cheap whore
And that is one of the many things that make her character unique. She’s not your typical NTR victim anymore; she’s the one doing the NTR.
