So, here's the "plot" I'm getting from this. The Bugster virus was wandering around the internet, and somehow infected Gai, causing Dan to be brought back to life. Gai has also built his own Humagear secretary, Rin (or Centi?). Because of Gai's infection, his Thouser suit darkened into ZAIA's suit.

Dan also uses probably Zea to rebuild his stuff like his Gamer Driver and Bugster Driver.

Oh my god I love this so much.

So basically the climax is going to be Gai regaining his Golden Soldier look and fighting against Zombie Gamer probably.

Because come on, if you're going to bring in Genm you gotta bring out his best suit.

I wonder whether or not there will be any new Rider Gashats or any new Progrisekeys for this short crossover.

The crossover that was demanded by virtue of sharing the same writer and (relative) character concept.

Gai actually makes all black work. And I can totally believe he would build himself his own Izu.

Here is the official synonym for the showdown between 1000% and Kami
With the collapse of ZAIA Enterprise Japan, Gai Amatsu establishes a new company with a secretary-type Humagear Rin. But something went wrong with his body, and Kuroto Dan appeared and separated from his body! The Bugster Virus, which was wandering in the internet and was revived by Ark and infected Gai! Gai transforms into Kamen Rider Thouser to try and get rid of the virus, but Thouser looks black for some reason.

I was about to say, "Wait ZAIA Enterprise Japan collapsed?"

Then I remember the last shot of the most recent Metsubojinrai trailer... and am like.

Ohhhhhhhhhhhhhh

Apparently Thouser is using his original Progrise Keys as opposed to ZAIA's. Weird. They really did retool the only Thouser suit they had lol

I think they still have the stage show suit? It'd be weird if they only actually had ONE Thouser suit. Him in the ZAIA suit is prolly cuz he's infected with the Bugster Virus.

That's the in-show reason. Real world reason looks to be that the Thouser suit doesn't exist anymore, only Zaia. Otherwise it doesn't really make sense for him to have the Zaia suit with his regular keys.

I know Thouser was perhaps only on like a second or third tier among the main characters, but it's a little mind-boggling to think they only ever had the one suit which they permantly painted black (although I'm less upset about that then with Ichigata, even though that's to be expected with a movie character)...

Gosh, now just imagine if all of Accel's appearances in the last decade were only in his Booster form. Or when Mach appeared in Over Quartzer, he was in his Chaser Mach colours!
