Pauliana reminds me of Joan of arc, here's a brief of Joan's story:
"Not just a legendary female warrior but also a Roman Catholic saint, Joan was but a girl when visions of the Archangel Michael drove her to approach the military of France's King Charles VII and offer to assist in his efforts to expel the occupying English in the later days of the Hundred Years' War. Though initially mocked by these men and soldiers, Joan was taken seriously once her influence ended the Siege of Orleans in nine days.
By age 17, she played a key role in commanding France's army, and her forte in the military seemed to be for strategy over slaying. The French owed much to Joan, and yet it was the Burgundians, Frenchmen loyal to England, that led to her demise."

I really liked the smut scenes bcuz the art was good (i.e excellent body ratio, no melon boobs/ass or rocket dick lol) and both looked sexy espically the female.
But the dialog was weird and funny somehow, also when the female mc was expressing her feelings in a repetative and teenage-ish manner which was a turn off for me at some point.
finally i can understand why felix sees that black bird during the manga and also it was in his painting. i think it's because of the accident, the image of that black bird covered in blood stayed in his mind.
thanks so much for the update
