Gekiga

Gekiga (劇画, lit. 'dramatic pictures') is a style of Japanese comics aimed at adult audiences and marked by a more cinematic art style and more mature themes. Gekiga was the predominant style of adult comics in Japan in the 1960s and 1970s. It is aesthetically defined by sharp angles, dark hatching, and gritty lines, and thematically by realism, social engagement, maturity, and masculinity.
