“You will be my partner for the upcoming Lunatic Night.”

──Thus, I was led to a grand mansion where the very man I had encountered on that fateful night awaited me.

In the bustling metropolis of Eastschist, the downtown area is whispered to be the most dangerous of all. A city alive with sirens that wail until dawn, it is a place where crime runs rampant, particularly on nights of the full moon.

Little do the people know that within this “melting pot of races,” creatures not of this world also roam.

On these perilous streets, where survival often means selling one’s body, Ange Blanc, an Omega, found himself on the brink of being taken by a member of the Mantegna family, the mafia that rules Eastschist. Just then, he was saved by a younger man with amber eyes, Aaron Tikaani.

To help Ange find work, Aaron offered him a position doing odd jobs at the upscale club owned by his brother. Enchanted by his amber eyes, Ange began to call him “Amber.”

However, since that day, he had not seen him again and instead caught the attention of Ian, Amber’s brother and the owner of the club.
