Hideki Tojo caricatures usually portray him in a very negative light. They could feature elements like a menacing look, weapons, or scenes related to the destruction caused by his decisions. These caricatures aim to remind people of his historical crimes and condemn his actions.
Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
