A 14-year old middle school boy who is the 22nd kekkaishi of the Sumimura 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. As a Kekkaishi, Yoshimori cannot be matched by his counterpart; Tokine in terms of power and speed, but his weaknesses lies in his lack of accuracy and tendency to tumble into a situation without thinking about it beforehand.
