Character: Sumimura Yoshimori

The main character. Yoshimori is a 14-year old middle school boy who is the 22nd kekkaishi of the Sumimura family. In the series, Yoshimori is portrayed as a lazy, stubborn headstrong creature who strives his best to protect his friends and his family. The younger Yoshimori was different from the current Yoshimori, in the fact that he likes to cry a lot more and who heavily dislikes executing his duties as a Kekkaishi. The situation that had brought about the change in Yoshimori was when Tokine was injured by an ayakashi which he could have dispatched, but did not due to his kindness, allowing the ayakashi to become more powerful and escape his barrier. Tokine had moved to protect him, destroying the creature but getting mauled in progress. After the incident, Yoshimori had changed drastically towards his attitude towards being a Kekkaishi. At the beginning of the series, he is often baking cakes and/or other sweets, and seems to be more important to him than his duty as a Kekkaishi. He has dreams to become an expert patissier where he can enjoy making pastry castles. He is often chastised by his grand-father for this hobby.

As a Kekkaishi, Yoshimori cannot be matched by his counterpart, Tokine, in terms of power and speed because of his lack of accuracy and tendency to tumble into a situation without thinking about it beforehand.
