Those Heart & Brain return to talk with Brain. Yes, I only saw them talk with Brain when he tries to explain them that he is also a Kamen Rider.
That new character Professor Crystal which is played by Belt-san's Actor Chris Peppler is going to help Brain to become Kamen Rider Brain.
Brain is also seen riding a bike which is clearly the repaint of Ride Chaser. I guess this bike is called Ride Brainer. Speaking of repaint, his Armor is the repaint of Gord Drive's. He is going to use Banno Driver to transform may be without Banno inside.
Well it is not known who is going to be the enemy in this but he is seen fighting Kamen Rider Duke, Kamen Rider Dark Kiva, Kamen Rider Dark Ghost, Shiroi Mahoutsukai & Gamma Speriol.
Hope he says "My Brain cells are on Top Gear!".
