Katsuki is a typically arrogant character who often is competitive and believes himself to be the best. He may be seen as disliked for being loud and aggressive, but he has good traits too. Always striving for improvement and to reach his goals and caring for his friends in subtle ways (Even though he masks it with indifference or annoyance).

Is an Omega but often doesn't let his instincts show. Has a caramel scent to his pheromones.
