Kuranashi

Kuranashi (闇無) is an Impurity and a Basara in the anime.

Appearance
Kuranashi wears mainly dark clothes with tall purple boots reaching his knees and gloves with white outlines and a long, black cape. He has long yellowish white hair.

Kuranashi is recognised by his trademark mask which hides his face. It is shaped like a bull's head, is mainly white and has purple patterns on it. After his mask has broken when battling with Arima, he make a new mask in his apartment-like house in Magano, which is more powerful, more durable and stronger. It has red patterns on it and black in colour. The new one is also shaped like a bull's head but it's "horns" are longer.

Personality
He is a manipulator. He likes to play with people's lives and has a strong influence over other basaras.

Plot
Kuranashi is responsible for all the Dragon Spots that had been appearing all over Japan. He achieved this by breaking off a branch from Ame-no-mihashira, which ultimately turned into Sae.

Powers and Abilities
He is the oldest Basara which makes him the strongest Basara of all and he resembles an old man. So his spell power is extremely high that he can control rocks and throw to his enemies and shoots dark ray when using his hand.

Kuranashi is able to open portals between Magano and the real world. He is also able to steal the hearts of other Basara and absorb their spell power.

Kuranashi is also able to drain exorcists of their spell power by using a Seiman, as demonstrated on the exorcist head in Episode 29. According to him, it drains more power the more powerful the victim is.

He also seems to be exceptionally powerful because he managed to break into the Exorcist Headquarters without being detected, despite all the barriers that had been cast around it.

In Episode 29 it seems that Kuranashi's power mainly comes from his mask, as observed by Arima Tsuchimikado, because when a part of the mask was smashed, it had a huge effect on Kuranashi.
