In the anime series "Tokyo Revengers," authority figures such as gang leaders, police officers, and other powerful individuals play a significant role in shaping the decisions and actions of the characters.

The influence of these authority figures can be seen in the characters' involvement in gang activities, conflicts, and struggles for power. Ultimately, the series portrays how the characters' choices are influenced and sometimes constrained by the decisions and expectations of those in positions of authority.
