Kyojuro is greatly enthusiastic in regard to his duties as a teacher, and often came across as cheerfully eccentric. In Kimetsu Academy, Kyojuro is a history teacher. Because of his passion of teaching and his love of history, he began hurling his students and starting cavalry battles during class. He's loved by his students, and nobody in this academy has terrible grades in history. He has a slight tendency not to listen at times, but is by far the most popular teacher in the school.
