Reinhard Tristan Eugen Heydrich ラインハルト・トリスタン・オイゲン・ハイドリヒ

The leader of the Longinus Dreizehn Orden. Originally a high-ranking official in Germany, regarded as highly dangerous due to his seemingly boundless talent in all fields. Later, he bowed out of the public eye through the guise of a staged assassination, and formed the Obsidian Round Table alongside Mercurius.

Their subordinate members acted behind the scenes of WW2 and kept on destroying friend and foe alike. His acts of destruction reached their climax during the fall of Berlin. However, he and his three direct subordinates disappeared shortly afterwards, leaving their current whereabouts a mystery.
