Powerful Crimsom Lord, old friend of Wilhelmina and former trainer of Shana with a rainbow-colored flame.
He's one of the Nine Eternal Divine Scales, the nine great Crimson Lords gathered under the name of Töten Glocke, the organization led by "Weaver of Coffins" Asiz.
Along with "Iron-clad" Illuyanka, he was feared as the "Pair of Wings". He then fell in love for the previous Flame Haze contracted with Alastor, Mathilde Saint-Omer, and after she defeated him, she made him promise not to eat any humans again, not wreaked havoc on Earth again, and train her successor, as she was about to use all Tenpa Jousai (Heaven Destruction Earth Break), to end the Great War that took place before the story of Shana, which resulted on her death due to the enormous power of existence released in the process.
After these events he takes the shape of a skeleton and the name of Shiro, to hide his past, and to protect what was left of his power of existence. Along with Wilhelmina he found and trained Shana, who was meant to be the next "Flame Haired Burning Eyed Hunter" and as a final act to honor his promise he used his last portion of existence to fight for one last time against Shana using his real shape. He´s a very skilled swordmaster and his special Power of Unrestraint is a rainbow colored beam of devastating power. He then die in Shana's hand, with a face on his face.
He was voiced by Katsuyoshi Konichi in Japanese, and Brion Dummond in English.
