Aside from the previously announced Akira Amemiya (Inferno Cop, Ninja Slayer) directing the project, who previously directed the 2015 Gridman anime short, it's also confirmed that veteran Ultraman writer Keiichi Hasegawa (Ultraman Dyna, Ultraman Nexus, Kamen Rider W) will write the series and will feature a Gridman designed by Masayuki Gotou who designed the recent installments of the Ultraman franchise.
The upcoming series is unrelated to the original 1993 tokusatsu series or its American adaptation, Superhuman Samurai Syber-Squad and will feature an original series. The series is set for an autumn 2018 release.
