Golgo 13

Golgo 13 is a Japanese manga series written and illustrated by Takao Saito, published in Shogakukan's seinen manga magazine Big Comic since October 1968. The series follows the title character, a professional hitman for hire. Golgo 13 is the oldest manga still in publication, and its tankōbon edition was certified by Guinness World Records as the highest number of volumes for a manga series. Before his death in 2021, Saito said that he wanted the manga to continue on without him; he had previously said that he was worried that the manga might be left unfinished. The Saito Production group of manga creators continue its publication with the assistance of the Big Comic's editorial department.
