Shin Himitsu Sentai Gorenger Gokko (真・秘密戦隊ゴレンジャーごっこ,Shin Himitsu Sentai Gorenjā Gokko) is a retelling of the original Sentai Series, Himitsu Sentai Gorenger. The manga was written by Shotaro Ishinomori, and released from May 4, 1975 to August 17, 1975. It was published in the Weekly Shōnen Sunday magazine.
Despite popular belief, this manga does not feature the children of the original Gorengers, rather, the Gorengers are mainly teenaged versions of themselves.
In many ways, this manga is similiar to the Kamen Rider Spirits manga, as both continued the story lines of their original series while diverging in places from the original, as Kamen Rider Spirits gave an alternate take on the story of Kamen Rider ZX.
Differences between the Manga and TV
How the Gorengers got their powers is told different from the TV series. In the manga, Akarenger receives his powers from his father, and the other Gorengers are given their powers from Akarenger.
