Teikoku Gunjin no Hanagurui

The red lightl district, where money is exchanged for relationships between males and females. Ryuren, an esteemed imperial soldier famous for his beauty, meets Mingmei, a girl in training at the Colourful Jewel Brothel. He is drawn to Mingmei, who has a hatred of men and "avenger's eyes," and he offers to pay to get her out of bondage.

"This feeling that is more sure than love and won't fade away, turn it only towards me."

A girl from an impoverished village and a top soldier. A twisted and intense pure love romance!
