Eris Floralia

Eris is a gorgeous woman who serves as the only female doctor in a red-light district, garnering high respect from many. Her medical expertise is unquestionable, yet she modestly charges just enough to get by.

Seven years ago, when she was nearly sold into prostitution, Caim stepped in and took her under his wing. After completing her medical education four years later, Caim asked her to live a free life without him, but she refused. As a compromise, she now lives in a different house and visits Caim's house regularly to cook and do laundry. However, Eris is a lousy cook and not particularly good at housework. Nevertheless, she is good at concocting medicines.

Eris doesn't take kindly to any woman getting close to Caim, especially Tia, who filled her shoes in Caim's house and took over cooking duties, whom Eris refers to as 'little critter'.

Spoiler

Caim's act of buying Eris' freedom was driven by a guilty conscience, a way to square things with himself for the death of her parents.
