Masamichi was always a stern, thoughtful, and earnest man who served as a positive role model for all his staff and students at Jujutsu High. He had a strong moral center and a lot of patience, especially compared to the higher-ups. He was the primary mentor for Satoru and Suguru, who were particularly difficult individuals to deal with when they were students. Satoru once left a manager behind and then forgot to put up a curtain during a mission.
