Long-long ago, there was a war that lasted over a century. It started between humans and monsters, who were separated by the mountains, cutting through the continent. The cause of this war has been lost in the chaos of history. All that remained was a cycle of grudges, as fighting led to more fighting. However, both humans and monster got tired of killing each other. Thus, ten years ago, they formed a non-aggression treaty and put the end to war. Old enemies are now best buddies and no one will be surprised to find a city, where both humans and monsters live. Of course, old scars are not that easy to heal and some humans discriminate against monsters and vice versa. The anime focuses on the town of Lindworm. Dr.Glenn is a human doctor that runs his clinic to treat monster girls. Of course, many injured girls appreciate the help of the doctor and make declarations of love to him. One day, the routine life of Dr.Glenn ends, when he discovers the dark side of the life in the city of Lindworm.
