Twin Star Exorcists
The 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", which allows them to combine their forces to increase the power of their attacks or access abilities that no other exorcist possesses. 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 <Sol>, made by Semei, (in this case, Rokuro) is a vessel for the Yang energy, and the Female Twin Star <Luna>, made by Doman, (in this case, Benio) is a vessel for the Yin energy. Both energies normally act as opposites to each other, but it is only through a fusion of both powers that the Miko <Taiji> is born, who is not a reincarnation of any spirit, but rather an embodiment of the two powers in one form.
The main protagonist. A brash and headstrong 14-year-old exorcist who was once motivated to be the strongest and cleanse all Kegare and sins. Rokuro was found by Seigen in Magano when he was 6 and had no memory of his past, after which Ryougo took him in. In the manga, he grew up in a valley of basaras before being found and taken in by humans. However, Yuuto Ijika caused a tragedy at the Hiinatsuki Dormitory which forced Rokuro to take the lives of his friends who had been forcibly corrupted. Following this, his right arm was corrupted as well and became part Impurity with great offensive power. This tragedy made him nearly abandon exorcism until he met Benio, who inspired him to fight as an exorcist again. Despite not liking the idea of being her groom at first, he later develops feelings for her. During the time skip, Rokuro elevates his studies and training, making him popular in high school. Rokuro becomes head of the former Adashino House on Tsuchimikado Island. In the climax of Kegare escaping to the surface, Rokuro and Benio are rejoined after a long separation. Benio's fate as an Impurity doesn't change Rokuro's feelings for her. The pair lived peacefully on the island for the process of four years. Rokuro soon obtains a fragment of Yuuto's yang energy that slightly awakens his own transformation. After persuading the islanders to make an exception to Benio's misconduct, she and Rokuro officially get married. When Benio couldn't keep her promise, Rokuro found it pointless and fully transformed into the <Sol>. Getting some pep talk from Seigen, Rokuro makes his quest to venture Magano to locate his wife and even forms a party with the redeemed Kamui and Suzu. Rediscovering his childhood home unknowingly kills Sutara, the Basara who raised him out of self-pity. Sutara's wife Asuha accepts Rokuro's generosity despite their differences.
In the manga, it is eventually revealed that the Twin stars are not truly human, and Rokuro is a vessel for Yang energy. He was created by Abe no Seimei, in other words, her son, so it appears as though his Guardian Spirit is Seimei, but in reality, neither he nor Benio has a Guardian spirit. In the anime, he is actually the Hajo-ó (Cataclysm King or Star Destroyer King), an extremely powerful Impurity created by Abe no Seimei who is destined to wipe out humanity should they become a threat to the world.
