Manga author Shun Kazami announced on his Twitter that plans to make a spinoff manga of the SSSS.Gridman focusing on the character Akane Shinjo have been canceled due to differences in the manga's story direction. Kazakami added that he has been struggling with the manga for over a year, but without progress, and apologized for the cancellation.
SSSS.Gridman premiered in October 2018 with 12 episodes and was directed by Akira Amemiya. Crunchyroll and Funimation streamed it while it aired in Japan. Pony Canyon and Tsubasa Productions announced in December that Trigger will animate the new anime project SSSS.Dynazenon , which is part of the "Gridman Universe."
Synopsis
Yuta Hibiki awakens with amnesia and the ability to see things others cannot. He first encounters Gridman in the reflection of his friend Rikka Takarada's computer, who tells him to "Remember your calling," but Yuta doesn't understand what this means. Later, in the distance, he sees a gigantic monster that doesn't move. However, when Yuta arrives at school, a monster attacks, and the image Yuta saw on the monitor pulls him inside and transforms him into the giant hero Gridman.
Furthermore, Kazakami launched the manga Ultra Kaiju Humanization Project ( Ultra Kaiju Gijinka Keikaku: feat. POP Comic code ) in Akita Shoten 's Young Champion in January 2015, and ended it in January 2020. Designer POP is credited with planning and creating original character designs, and Tsuburaya Production is credited with the original artwork.
