September 9—the start date of the serialization of Hajime Isayama’s wildly popular manga *Attack on Titan*—has been officially designated as “Attack on Titan Day” by the Japan Anniversary Association, a general incorporated association.
To mark the establishment of this commemorative day, three special events will be held on September 9, 2026: a 99-hour limited-time free release of 99 chapters on Magapoke; the release of commemorative merchandise at the Magazine Shop; and a special live stream featuring voice actors including Yuki Kaji.
