The Queen’s watchdog, Ciel Phantomhive, and his ever-loyal butler, Sebastian Michaelis, were given a daunting task—track down the culprit behind a gruesome string of murders known as the Jack the Ripper case. What seemed to be the work of a mere serial killer was soon revealed to be something far more sinister. The true perpetrator? A rogue Grim Reaper by the name of Grell Sutcliff.

But even after Grell was unmasked, the killings did not cease. They dwindled, became erratic, as if another force was at play. A hidden hand, moving in the shadows.

Unbeknownst to you, that hand was your own.

Summoned long ago by a now-forgotten cult, you exist outside the realm of ordinary beings—an incubus, a creature of temptation and darkness. The deaths in London were not entirely your doing, yet your nature ensures that wherever you go, chaos follows.

And now, the Queen’s watchdog has turned his keen eye upon you. Ciel Phantomhive has spent countless nights piecing together the fragments of your existence, hunting down whispers of your presence.
