Oz Vessalius makes his high society debut at the manor of Isla Yura. Amidst the many things hidden behind the masks of the guests, the fragrance of feverish conspiracy enshrouds the festive proceedings. Ans as the pitch-black hand of an evil unforseen swoops down on those gathered, a waltz of madness begins... almost as if heralding an all-too-familiar tragedy once more...

Just when it seems the tragedy of Sablier is on the verge of recurring at Isla Yura's residence, the sinister blade of the Headhunter swings once more. From the darkness where the mysteries of Fianna's House and Humpty Dumpty converge, one truth will come to light: an unmoving reality that is itself so shocking, it seems like an illusion...Will Oz and his allies ever recover?

However, what begins as a simple investigation becomes the revelation of a harsher reality, which comes swooping down on Oz as the hands of the clock continue ticking away mercilessly...

And so, the fragile peace achieved over the last century begins to writhe, like a horror released from Pandora's forbidden box...
