The Moonlight (German for Moonlight) are a group of individuals who can only survive by consuming human blood and must avoid sunlight. Despite their fearful nature, they primarily seek survival without harming others or being hunted to extinction. However, things became even more challenging when an artificial human named F08, created by Dr. Frankenstein, began hunting them down. During her first confrontation with the Moonlight, F08's "big sister" turned against her after killing a boy leading the group. This raises questions about whose side she is on and why she possesses wings like those of the vampires she hunts. Can the Moonlight ever find peace amidst these challenges?
