Eleonore von Wittenburg, also known as Samiel Zentaur and later Rubedo the Red Knight, is a core member of the Longinus Dreizehn Orden holding Seat IX at the Black Round Table. She ascends to become one of the Three Knights (Einherjar), serving directly under Reinhard Heydrich within the Longinus Thirteen's leadership and playing a key role in the Transmutation of Gold. Before World War II, Eleonore served as a Gestapo lieutenant alongside Beatrice Waltrud von Kircheisen. Her life altered irrevocably on Christmas Eve 1939, fighting serial killers with Beatrice and witnessing Reinhard Heydrich's supernatural transformation. Fierce loyalty nearly cost her life when news of Reinhard's supposed death triggered a battle error, leaving severe burns scarring half her body. Reinhard's subsequent visit, praising her beauty despite the injuries, deepened her devotion and romantic feelings, cementing her oath to follow his World of Gold eternally. After learning the Ewigkeit formula, she participated in the Berlin ritual, ascending with Reinhard to a higher plane detached from the World of Omega Ewigkeit. She eternally fights and resurrects in Gladsheimr alongside fellow commanders Wolfgang Schreiber and Machina (Göetz von Berlichingen) to fulfill the Transmutation. Eleonore exhibits a strict, commanding, and brutally efficient personality, embodying the knightly ethos of honor, loyalty, and directness. She holds deep contempt for cowardice, underhanded tactics, emotional weakness, or reliance on indirect powers. Her loyalty to Reinhard is absolute and all-consuming; any perceived insult to him or her fealty provokes lethal retribution. Despite her pride, she respects worthy opponents and may offer combat advice. A longstanding rivalry existed with Lisa Brenner, dating to their pre-WWII youth, where they competed in various fields – Lisa leading the Lebensborn program while Eleonore pursued a military career. This rivalry intensified into hostility fueled by Eleonore's jealousy over Lisa's romantic involvement with Reinhard and her perceived responsibility for Beatrice Kircheisen's death. During the events of *Dies Irae*, Eleonore confronts Lisa Brenner in Gladsheimr during Rea's route. Despite easily overpowering Lisa due to their power disparity, Lisa lands a slap and accuses Eleonore of jealousy over "stealing her men." As Lisa dies on Eleonore's chest, she urges her to release the past. Eleonore later battles Ren Fujii alongside the other Einherjar. Initially overwhelmed by Ren's speed and stagnation (using Eine Faust Finale), they survive when he retreats to save Rea. At the peak of her power after the eighth Swastika opens, Eleonore and the Einherjar overpower Ren. However, when Ren reconnects with Marie and attains the rank of Atziluth, Eleonore is effortlessly killed. During Reinhard's final clash with Mercurius, she is summoned within Reinhard's pseudo-God legion, her flames now capable of contending with Mercurius' Sequere Naturam. Eleonore's reincarnation, Ryuumei Mikado, appears in the Eastern Expedition within *Kajiri Kamui Kagura*. The *Omnia Vincit Amor* epilogue depicts her reincarnated as a university student in modern Germany. Conversely, *Nihil Difficile Amenti* shows her perishing in a 1943 war, an outcome granting Lisa Brenner a sense of pride for outliving her. As an Ewigkeit master, Eleonore wields key abilities: * **Yetzirah: Der Freischütz Samiel**: Her Holy Relic manifests primarily as a World War II-era railgun tank (Eisenbahngeschütz Schwerer) firing shells with explosive force exceeding nuclear warheads, consuming body and soul. It can also manifest as other WWII weaponry like grenades, rifles, or anti-aircraft cannons. The relic strikes physically and spiritually but suffers low mobility. * **Briah: Muspellheimr Lævateinn**: A Hadou-type Briah fueled by her craving to "burn forever in the glow of Gold." Its incomplete form generates infinitely expanding flames engulfing the target, bypassing fire resistance and burning the soul. Its true form transports opponents into a cross-dimensional realm of endless hellfire inside her cannon's barrel, where escape is impossible without teleportation. Her relic remains usable, firing unavoidable flame bursts. * **Immortality and Regeneration**: As an Einherjar, she possesses multiple immortality types: Type 1 (agelessness), Type 2 (surviving decapitation), Type 3/4 (High-Godly regeneration/resurrection within Gladsheimr, recovering from destruction of history, concept, and information), Type 7 (existence as a dead entity), Type 8 (immortality linked to Reinhard's existence). Her battle parameters evolve: Yetzirah (ATK 5, DEF 5, MAG 7, AGI 2, EQP 5) and Briah (ATK 7, DEF 6, MAG 2, AGI 3, EQP 6), or Formation (ATK 5, DEF 5, MAG 3, AGI 3, EQP 5) and Creation (ATK 6, DEF 6, MAG 4, AGI 4, EQP 6). Her threat level escalates from Dragon- to Dragon+ with power growth tied to Reinhard's emanations. Key weaknesses include standard Ewigkeit vulnerabilities and her loyalty potentially clouding judgment if Reinhard is threatened. In restricted states, resurrection isn't instantaneous, potentially taking days to years. Trivia notes include her leitmotif "Einherjar Rubedo" and the dynamic among the Three Commanders resembling "rock-paper-scissors": Schreiber cannot evade Samiel's attacks, while Machina can destroy Samiel in one punch. Her demon name references Samiel, the "Black Huntsman" from the play *Der Freischütz*.
