One of the most powerful Crimson Lord that Shana and Yuji fight with. He´s a remarkably skilled assassin that enjoys killing his prey, as long as he gets paid, and doesn't care if they are humans, flame hazes or denizens.
He likes to make long fancy-talk speeches, and while he is seen dissatisfied many times, it is hard to see him in a wrath. His hobby is collecting bladed weapons, from swords to katanas, whether they are Treasure Tools or not, and he actively use them in his fights.
He wears black clothes, a cape, a mask to cover his face and also a leather-bandage. His hair is black and his eyes are illustrated with narrow eyes with a red glowing light.
He has a mission to kill Yuji, and made his entrance in a quite shocking way, injuring everyone with his special surprise attack. This power of Unrestraint leaves a wound that keeps growing with time, so even if you survived you´ll be in grave danger, however this surprise attack can only be performed ones and hopefully for Yuji, Shana and Wilhelmina they had acquired their own response against the devastating effect of this attack, the healing power of Unrestraint developed by the very own creator of the Reiji Maigo, and old friend of Wilhelmina, who had ironically deceased by Sabrac´s attack. But even after nullifying Sabrac´s first attempt to kill them, he was still a very powerful opponent and drove Wilhelmina and Shana to their edge, no matter what they did he seemed immortal. It was Yuji the one that discovered Sabrac´s secret, his true form wasn´t that of the skilled ninja fighting with them, his full body was hidden in the underground of the hole Misaki city, so thanks to the help of Margery Daw they could separate both parts of Sabrac and blast him with an ultimate attack. However Sabrac was badly injured but not completely eliminated because he was fast enough to scape at the last minute leaving them for the moment.
