Befitting of the Ultimate Moral Compass, Kiyotaka is righteous and values order and rules above all else. He takes his role as a student very seriously, shown when he gets upset that there are currently no classes going on during the Killing School Life. He also states he has 10 sets of his uniform so he never runs out and so he is able to wear one every day of the year, even on holidays or days off from school. He is shown to be very polite and respectful, as in original Japanese release, he addresses people, even girls with "-kun" honorifics.
