Hellsing Organization

The International Hellsing Organization of Contracted Monster Slayers, sometimes simply known as the Hellsing Organization, was a group created in the late 15th century and later refounded sometime after the Apocalypse, both times with the explicit purpose of destroying vampires and other "supernatural" monsters; though the exact definition of "supernatural" and "monster" seemed to vary by the current leader and often on a case-by-case basis.
