Keith deliberately presents himself as imposing, strict and frightening, and because of this most of the trainees from the 104th Squad remain wary of misbehaving around him. He shouts and commands at the top of his voice, putting the trainees into submission and fear. He is observant and has the ability to discern the character traits of other people by their expressions, mannerisms, actions and abilities, as shown when he gives a character analysis of some of the trainees of the 104th Squad. Rough sounding voice.
