The ending of Kamen Rider Brain had revealed that Gou Shijima (Kamen Rider Mach) was working on some Project called Neo Core-Driviars for Kamen Rider. He was seen reviving Heart, Medic, Brain & also Chase through available data. Proto Zero was also seen there.
A week back Suit Actor Jun Watanabe who was also the Action Director for Kamen Rider Brain had teased about working on another work around the same time. Could this be related to this Neo Core-Driviars? A Sequel for Kamen Rider Drive? or is it something to do with Kamen Rider Zi-O Drive Part?
