Lynn's world changes drastically when she encounters "Arne", a vampire who is called "the worst" in the city.
And tonight, a new "murder case" has occurred.
What is the truth behind the bizarre incidents that take place in a world where humanity and the bizarre intersect?
"Come on, human. You may dance merrily under the crimson moon.”
