The Twin Star Exorcists are a couple of exorcists destined to be the parents of the "Miko", the reincarnation of Abe no Seimei and the ultimate exorcist that is said to be capable of cleansing every kind of evil spirit. The Twin Star Exorcists also have a special, exclusive ability called "Resonance", that allows them to combine their forces to increase the power of their attacks or access abilities that no other exorcist possess. It is also revealed that the Twin Stars are not proper exorcists, but rather "Vessels" made by Abe no Semei and Ashiya Doman. They do not have guardian spirits, but rather their powers come from the entire world around them. The Male Twin star, made by Semei, is a vessel for the Yang energy and the Female Twin Star , made by Doman, is a vessel for the Yin energy. Both energies normally act as polar opposites to each other, but it is only through a fusion of both powers that the Miko is born, who is not a reincarnation of any spirit, but rather an embodiment of the two powers in one form. ;Rokuro Enmado ;Benio Adashino
The Twelve Guardians, literally meaning Heavenly Commanders, are a group of twelve elite exorcists stationed on Tsuchimikado Island, the place where Magano was first created, to prevent the Impurities from overrunning the mainland. Second only to Arima Tsuchimikado among the exorcists in power, each use one of the twelve familiars of Abe no Seimei and inherit a portion of his power through their use of his familiars. The twelve families that they come from are descended from the twelve original companions of Abe no Seimei. In the anime, they are not stationed in Tsuchimikado, and usually perform missions across the country in pairs.
The Basara are the most powerful Impurities in existence with each gaining intelligence, speech, and a human-like body by absorbing the energy of the exorcists they killed. Like exorcists, they can use their own version of enchanted gear and talismans to strengthen their powers. Unlike regular Impurities, their bodies do not disappear once they are killed. In the manga, there are a total of 11 in existence while several 7 original Basara were created exclusive for the anime series. ;Chinu ;Sakanashi ;Gabura ;Hijirimaru ;Shiromi ;Kaguya ;Gaja ;Shioji ;Higano ;Yuzuriha ;Kamui
