This monumental manga became the driving force behind Shonen Jump, the tough kid boss of the neighborhood, Mankichi Togawa, sets out on a quest to become the number one gang leader in Japan. This series, which was followed enthusiastically by the youth of the time, blazed the trail for a new class of readers. This work embodies the spirit of the magazine Shonen Jump. It had a major influence on the authors who followed. In 1969, it became the first Shonen Jump work to be turned into animation, and in 1971 it was turned into a live action film.
