As Ion's most trusted friend, he was sent to accompany Ion to negotiate with the Vatican. He was controlled by Dietrich von Lohengrin and worked for the Rosenkreuz. His first task was to kill Ion Fortuna (his childhood friend) of the New Human Empire and later plotted to assassinate the Empress. He possesses a unique ability to produce and control blue flames. His spilled blood appears as blue flames. He was supposedly 'killed' by Sister Paula, but survived the attack and seized his chance to take control of the Inquisitorial Department's weapons. After his death following his battle with Abel's Crusnik form, he was reanimated and controlled by Dietrich. He was finally completely destroyed when Seth transformed into her Crusnik form and disintegrated his body. (Flamberg may be a Germanised form of the French flamberge, a kind of sword that, as a form of intimidation, was forged in the shape of a tongue of flame. Radu himself shares his name with Radu cel Frumos, brother of Dracula.)

Forced to kill his former partner Ion during the mission, he fails and is killed by Sister Paula.
