Madarao

Madarao is one of the Third Exorcists, a half human, half Akuma hybrid created through the Third Exorcist Program. A man of medium height, with short hair besides a length that falls down over his face on his left hand side. He is implied to be the leader of the Third Exorcists or at least the most senior, as Tokusa scolded Koushi by asking if he wanted to be told off by Madarao on the first day for his lack of control on meeting Allen Walker.

Timothy Arc
Madarao and his sister Tevak are first seen during the Timothy arc, when four Skulls used their combined magic to create a barrier around Timothy’s orphanage to prevent anyone besides Akuma from entering the building during the battle. While the science department discovered and attempted to penetrate the barrier themselves, Tevak, who is posing along with her brother as guards for section leader Reever of the science department, comments to Madarao that something is not right with the building. Madarao later strolls up to the door of the orphanage, even as the scientists continue to try to penetrate the barrier, and commands it to open, creating a doorway in the barrier, shocking everyone, including the watching skulls.

Madarao proceeds to attack the level 3 breaking through Howard Link's own barrier, sending the Akuma flying with his own spell and then activating his Akuma powers and devouring the level 3 with no difficultly. Howard Link is left shocked, both by the presence of the CROW member and the incredible power displayed that he had no idea a member of CROW possessed.

Noah Revival Arc
Back at headquarters, the mystery around Madarao and his fellow CROW members is revealed when orders arrive from the pope and the Vatican that the Third Exorcists will be stationed at the Black Order Headquarters from now on, to assist the Exorcists in their war against the Akuma. Madarao and Tokusa later appear to help Allen Walker fight off a host of Akuma in the Middle East, only to be driven off in turn by the arrival of the Noah, who have began their true assault on the Black Order. After Tokusa is gravely wounded by Tyki Mikk, he begs Madarao to devour him so he may live on in future generations of Third Exorcists. However, before Madarao can do so, they are ambushed again by the Noah, who separates them. Madarao is later revealed to be being taken care of by Mercym, the Noah of Mercy. His current whereabouts and status is unknown.

Trivia

 * If Madarao truly is the leader/senior member of the Third Exorcists, then this could imply he is either the strongest of the current five or his control over his Akuma powers is more refined and precise.
 * Madarao has black feathers fixed to his haircut (it's possible that they're crow's feathers)
 * one of the members of third exorcists/CROW- Tevak - is his sister
