Kiyotaka is a relatively reserved person who tries their best to be professional. On the job, Kiyotaka confidently fills his role as head manager of Jujutsu High while working alongside students or other managers. However, he does have a tendency to get very nervous when things go awry. This especially applies to anything involving his friend Satoru Gojo. Satoru can end up belittling Kiyotaka from time to time, frustrating him.
