That's because it's not. This morning, it was confirmed that Akiba Blue will be played by new actress, 14 year old Sawada Shione. She'll be playing new character Iwashimizu Mitsuki.

Yes, that's right, she even has the same first name as the old Akiba Blue.
It's confirmed that Malshina and Hakase will both return, and we know that a new character will be introduced named General Tsuu, who from his name, is very likely some kind of villain. He will be played by legendary voice actor Horikawa Ryo, voice of characters such as Vegeta, Heiji Hattori from Detective Conan, and the masked villain Karasu from Yu Yu Hakusho.
Also noteworthy in the cast is that Akiba Yellow is now listed by her "real" first name, Yuko, but her last name is Yokoyama rather than Yamada. Could Akiba Yellow have gotten married in the year since we saw her last? Are we about to get a MagiRanger joke and have her husband become one of the heroes?
