There's a light novel coming out called SSSS.Gridman ~Another God~, which apparently focuses on another being around the same time of the series

There's Comicalize SSSS.Gridman, which is an adaptation of the anime

There's Neon Genesis Junior High Students' Diary, which is a comedy series focusing on the four students

There's The Princess and the Samurai, which involves Samurai Calibur and a girl named Hime, who has Samurai's fifth sword.

There's two untitled manga, one focusing on the four students dropped into a game and become butlers and one focused on Akane

There's also a "Sengoku Gridman" manga coming out

Yeah. Makes sense; it was 2nd highest in the ratings for its season in Japan, iirc.
