The Psycho-pass writers went to a lot of trouble to parallel the gym scenes for Kougami and Tougane in the second ep, and I think I may have an idea why.

Neither Kougami nor Tougane are the actual main or POV character—that’s Akane. What they are, I think, are the characters who set the tone for the season and give us cues for how to understand the action.
