Reinhard Tristan Eugen Heydrich (ラインハルト・トリスタン・オイゲン・ハイドリヒ)
Background
During the start of the series, during World War 2, he and Mercurius propelled the castle Gladsheim outside the current confines of reality and have been waiting ever since for the completion of the Swastika in Shambalah.
A charismatic figure, Reinhard's mere presence is enough to rob his enemies of their will to fight. A mere gesture from his shade is enough to strike fear into the hearts of the strongest of warriors. Wielding the Holy Lance of Longinus, Reinhard is undoubtedly one of the strongest, cruelest and most lovable characters in the entire series.
