Kurogiri has a level-headed personality, which often serves to ground Tomura's immaturity and temper. He is intensely loyal to both All For One and Tomura, having been created to watch over the latter. As a Nomu, Kurogiri is programmed to only obey commands from a select few and will remain silent towards any attempt to extract compromising information about the League from him. Kurogiri is very polite and well-spoken even to his enemies, sometimes introducing himself in a formal manner.
