Lullaby video of Demonia call

When misfortune strikes and you're forced to throw yourself on his royal mercy, he has a proposition for you—work as custodian of his vast collection of relics in exchange for refuge and a means to earn your freedom. The only catch—you also have to serve as personal maid to his four capricious sons, the Princes of Pride, Greed, Lust, and Envy.

One day, for some reason, you find yourself inside the forbidden clocktower that stands in the middle of the town. Inside, you meet an enigmatic young man who claims to be an “observer.” He claims that this world has been twisted by evil and entrusts you with a key that will supposedly help you return it to its true state.

Guided by the mysterious key, you unwillingly release three dashing Demons. Are they truly the sinful beings that everyone says they are? What secrets do their titles hold? Will the key be the secret to not only letting them free, but also unlocking their hearts? Later, he shows up at your house and you decide to help him only to discover that he’s half vampire and half werewolf! How could such a thing be possible?! To make matters more complicated, the werewolves have sent an investigator to capture him! Soon you find yourself caught up in the war between two races and find out that the peace you were used to was not what it seemed to be… But these dire times might just lead you to discover bonds that will last a lifetime. Will you be able to bridge the gap between two warring races?
