Mondlicht: Tsuki no Tsubasa

A group of vampires known as Mondlicht cannot leave during the day and must feed on human blood to survive. Despite this, they are mostly scared children trying to avoid killing people or being hunted. Their struggle becomes more difficult when F08, an artificial human created by Dr. Frankenstein, begins searching for them with the intent to destroy them. During F08's first encounter, the girl she considers her big sister betrays her after killing the Mondlicht's leader. Her allegiance is unclear, especially since she has wings similar to the vampires she is supposed to hunt. The future of the Mondlicht remains uncertain as they question whether peace is possible.
