Yeah, I got this info from another forum. I'm a bit disappointed about it when I heard that Akibaranger, but since it is an experimental series I think Toei probably didn't want a long-term committment. Perhaps they could give it extension if it exceeds expectation, but there is no precedence for a series like Akibaranger so your guess is as good as mine.

Akibaranger is the kind of show I could imagine getting multiple seasons spaced out, so I guess time will tell how long it lasts.

Looked it her up on Google images.
Yeeeeep, though I bet a noticeably amount of Sentai actors have done some nude work.

She's not the first, Go-Onger's Kegalesia has done some AV work too.

I'm really enjoying this show more than Go-Busters.

BTW, Toei has had the recurring trend of casting AV Idols into Super Sentai and Kamen Rider for decades. The earliest I've known was Zonnette from Gekisou Sentai Carranger.
