The Reaper, also called Black Ghost is an identity attributed to a human crime lord, the infamous head of the Assassin's Brotherhood. Almost nothing is known of The Reaper, as few have seen him and lived to tell of it. He is believed to be wealthy, well connected, brilliant, and a lethal assassin and gunman. It is also believed that he possesses the loyalty of a an ancient witch named Maghda.

The Reaper's twisted childhood left him with no care for the lives of others. So, it is believed that he got into crime, a fascination for killing in particular. He started off small and quiet, however he worked his way up the crime scene until he recruited many of the finest professional murderers on the planet, forming the Assassin's Brotherhood. His wealth accrued, and it's postulated that he became a millionaire, one of the richest men in the world.

Today, he still runs the guild in secret, yet to be put to justice.
