Thanks to 4chan’s /m/ board, we have some more information about Hikonin Sentai Akibaranger! A synopsis is as follows:

“The main characters are three dwellers of the depths of the enthusiast gathering computer district, who inadvertently discovered the wicked existence threatening their town. Armed with the super equipment developed by the achingly beautiful and brilliant professor, they set out to destroy evil and protect their Holy Land of Akiba….”

The show is being tagged by Toei as “a forbidden series meant for adults!” The show was even tagged with the line “Good kids, stay away from this show, got it?” No, this doesn’t mean we’re getting Garo as a Sentai series. I think it’s safe to say we’ll be in for a Sentai filled with fan service. Speaking of, the show is rumored to have four main cast members: the three Akibarangers, and that “beautiful and brilliant” professor.

Red: A boy. Very shy personality. Probably a DT (a virgin).
Blue: A young lady with long, black hair. Has a flatter chest.
Yellow: Brown haired girl. Huge breasts. (As evident by the above suit design.)
Professor: Sexy older sister type. Loves pranks and wears glasses.

As posted by Ryokuya before , the Tamashii Features Vol. 3 will be hosted in Akihabara on March 31st and April 1st. More information is bound to be revealed!
