Siegfried was a member of the Khaos Brigade's Hero Faction and the descendant of Siegfried of the Nordic legends who was the first wielder of Gram. He was one of the top two swordsmen of the Khaos Brigade alongside Arthur Pendragon of the Vali Team, and was known as The Demonic Sword User and "Chaos Edge" Sieg.
He's a handsome young man with silver-white hair.
Little has been mentioned of Siegfried's personality besides the fact that he was a dedicated swordsman and the rival of Arthur Pendragon. He has also shown to have a little regard for his own life using the Demon Swords that cut down his life span without any regard.
In the past, Siegfried worked for the Orthodox Church, and was trained in the same institution that trained Freed Sellzen. He was considered the best swordsman after Dulio Gesualdo, bearing the nickname "Chaos Edge" Sieg (魔剣（カオスエッジ）ジーク Kaosu Ejji Jīku), but he eventually left the Church and joined the Hero Faction, where he had started a rivalry against Arthur Pendragon and was very upset when Arthur joined the Vali Team.
In Volume 7, he is seen discussing with Cao Cao on their next course of action.
He made his first official appearance in Volume 9, while he and the rest of the Hero Faction are at Kyoto, kidnapping the leader of the Youkai under the intention of using her as a substitute to open the Dragon Gate and summon Great Red. He later fought Kiba and Xenovia by himself and defeated them with ease after revealing his Balance Breaker. When Sun Wukong came, he attempted to fight the monkey but was defeated in one attack. He and the other members of the Hero Faction were then forced to retreat.
In Volume 11, he came to the dimension created by Georg using Dimension Create and had a rematch with Kiba, resulting with the latter cutting off one of his Dragon arms. After the sudden appearance of Shalba Beelzebub who appeared with a kidnapped Leonardo who forcefully activated Leonardo's Balance Breaker, Siegfried and Georg take Leonardo and retreat.
In Volume 12, he and the members of the Old Satan Faction went to Ajuka Beelzebub's hideout in the human world intending to form an alliance with Ajuka but were rejected, He then fought against Yuuto for the third and final time. During the fight, Siegfried injected the blood of the original Satan into himself which he called Chaos Break. This made his body undergo a demonification process where he transformed into a monstrous spider and fused with his Demon Swords and Sacred Gear. With this new form, Siegfried easily overwhelmed all the members of the Gremory group, cutting off Yuuto's left arm and injuring both of his legs. The battle was overturned when one of Issei's Evil Pieces transformed into the Ascalon, allowing Yuuto to injure Siegfried. Siegfried finally lost to the latter after his strongest Demon Sword, Gram, abandoned him and chose Yuuto as its new wielder. As he received attacks from the Gremory group, with Yuuto dealing the final blow by stabbing him with both Gram and Ascalon, his body starts to crumble. After that, when asked by Yuuto on why didn't he use the Phoenix Tears, Siegfried responds by saying that when using the doping of the Satans' blood, they cannot use Phoenix Tears as his body crumbled to his death.
