Manga and Anime Legacy
Shingeki no Kyojin is a dark fantasy manga by Isayama Hajime that ran in Bessatsu Shonen Magazine from 2009 to 2021. The series has surpassed 140 million copies in cumulative circulation worldwide.

The manga first began serialization on September 9, 2009, in the inaugural issue of Bessatsu Shonen Magazine. That date has now been formally certified as “Shingeki no Kyojin Day” by the Japan Anniversary Association.
