The Melancholy of the Prostitute Elf

A small village of elves are quietly living nearby to a forest while watching over the world's life and harvesting its mana.
However, the village is attacked by greedy humans who kill all the elven men and make the elven women become prostitutes.
The high elf woman who was the village chief vows to rescue everyone but gets tangled with a regular who frequents her.

Note
As it usually happens in hentai self-publishing, the story is told in six doujinshi that would make six chapters if collected in a volume.
