What is the name of the artstyle used in so many anime portraying certain emotions/actions of rage?


I see this art style in certain frames of animes when a character is consumed
by rage or when an action like a fire occurs. This is common in manga and
anime like _Fire Force_ , or Gon's rage scene.

I would like to look at more works like this as a reference, but I can't seem
to find the name of the art style.




Tsumi-e in negative (whites appear blacks, and darks to lights) for impact
frames. Maybe I'm stating the obvious here.
