Enderle Koutza
In the manga and the novels, his name is Endre Kourza. He is the Count of Zagrev of the New Human Empire.
Known as the Empire’s worst mass murderer, Enderle particularly enjoys slaughtering his victims. After his exile from the empire, he associated himself with the Order of Rosen Kreuz and continued his crimes in Venice. He was found by Astharoshe Asran and Abel Nightroad, who had orders from their respective superiors to arrest or eliminate him. Avoiding his pursuers, Enderle plotted to assassinate Pope Alessandro. His plans ended in failure when he was shot with a silver bullet by Abel Nightroad. During his transportation back to the Empire to await judgment, he was killed by Isaak Fernando Von Kampher. (Note: His connection to the Rosen Kreuz and his death are only revealed in the original novel.)
