These are Rokuro and Benio wearing the uniform of the Tsuchimikado Island with the coat of arms of the Enmado House
The House was formerly that of the Adashino Family but following the deaths of the parents and subsequent events that led to the house being looked on with contempt the house fell into poor state. The house was on the verge of being torn down but in order to prevent the house from being destroyed Rokuro Enmado stepped in and declared it as his home. He proclaimed that he won't allow the house to suffer anymore misfortune and stated to spectating Heavenly Commander Tatara that he will make it the highest ranking house on the island.
This news amused Tatara as Rokuro shrugged this off and told Adashino family Shikigami Kinako to help restore the house in order to have something to show Benio which caused the latter to take his hand in gratitude.
The news of the House being made spread through the island as exorcists everywhere were in disbelief that one of the Twin Star Exorcist would form his own House instead of joining a prestigious rather than one that has seen better days.
In the Enmado House first few days, Kinako tried to get Rokuro to forget the house and join one of Heavenly Commander's house but Rokuro stood by his decision especially when Kinako told him of a way to get more members was through Exorcist's Games.
The house would soon earn a new member in the form of Arimori Tsuchimikado who decided to join the house which earned shock from Kinako as Arimori already came from a well known family. Arimori had stated he joined the house to make Rokuro his servant and with his well known reputation he could Rokuro more followers. To his shock, Rokuro denied him but at Kinako's urgings he begrudgingly gave Arimori royal treatment until the latter's father arrived and scolded his son's actions.
He threatened Arimori with disownment from the family, and Arimori was close to breaking down but Rokuro stepped in and declared Arimori as a member of his family and since Arima brought up disownment Arimori was more than welcomed in. After seeing Rokuro's character and him defending him from his father, a touched Arimori swore his allegiance and loyalty to Rokuro. Kinako again wondered why Arimori joined them before deducing the latter did so to be acknowledged by his father which was confirmed through his facial expression. Rokuro nearly reconsidered his choice since Arimori has father issues which the latter denies.
