Personality. 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.  He is very expressive and intense in his manner of speech and is almost constantly shouting. Due to his lack of social skills, he often bursts out the first thing that comes to his mind and forces his values and beliefs on others, which he's aware of and feels guilty about. Possibly because of the lack of social interaction.
