Yoshimori Sumimura (墨村良守)
Yoshimori is the 22nd Kekkaishi of the Sumimura family. Throughout the series, Yoshimori is portrayed as a lazy, stubborn, headstrong individual who strives to protect his family and friends, especially Tokine, who he's had feelings for since childhood. When Yoshimori was much younger he often cried a lot and strongly dislikes being a Kekkaishi. Yoshimori's attitude greatly changed, however, after Tokine's arm was injured by an ayakashi that Yoshimori failed to eliminate. At the beginning of the series, he is often seen baking, an activity he often finds more important to him than his duty as a kekkaishi. He dreams of becoming a patissier, but is often chastised by his grandfather for this hobby.

Yoshimori's skills as a Kekkaishi differ from those of his counterpart, Tokine. Due to his rash and headstrong personality, Yoshimori has always fallen behind Tokine in terms of speed and accuracy. However, in terms of sheer power and stamina, Yoshimori excels. He is capable of creating extremely powerful and large kekkai, kekkai which Tokine is either incapable of forming or those which would quickly exhaust her. Throughout the series, observations had been made by Sumimura Shigemori and Sumimura Masamori that Yoshimori has an enormous wellspring of latent abilities in his kekkai. It has also been noted that Yoshimori is able to activate zekkai without any particular training beforehand. However, his zekkai could only be powered to its full potential in moments when his emotions overflow their boundaries.

Tokine Yukimura (雪村時音)
Tokine is 16 years old and the 22nd Kekkaishi of the Yukimura family. She bears a scar on her right hand, which she received while protecting Yoshimori in their childhood. Tokine is gifted with great accuracy and precision, however, her kekkai are very weak and can only be maintained for short periods of time; her kekkai lack the "brute power" of Yoshimori's kekkai. At first she attempts to make up for this by copying Masamori's technique of stacking several kekkai's around a target, but this takes too much stamina for her, making the technique ill-suited for her. Later, she learns to refine her kekkai into narrow "spears" that can impale and imprison an enemy, making up for her lack of power. She also has the ability to manipulate kekkai and space, this is seen when she cannot dispel Yoshimori's kekkai and so manipulates it so she is able to pass through it and then again during the time a user kidnaps members of the Yagyou she uses his portal to enter the dimension he created. Tokine is clearly impressed by the power and potential Yoshimori has, but is constantly frustrated by his poor control and lazy attitude. She cares for Yoshimori and often protected him many times when he was younger. She also likes to tease him and isn't aware of his feelings for her, although as the story progresses she begins to shows signs of deeper affection for Yoshimori, she once slapped him so hard he passed out for going off to fight Kaguro and trapped him with neshi and beat him when he left to Okuni without her. In the series, it is stated that whilst she may be the weakest Kekkaishi, she is clearly the most "ruthless", unless she must face her biggest fear: the cockroach. Examples of her ruthless pragmaticism are her disregard for the health of Hachiouji Kemiya when he was possessed by an ayakashi and forbidden metsu of a shinyuuchi god that had invaded karasumori and attacked its defenders.
