Which final form ride did Decade use the most?

I'm actually wondering what "vehicle" other than his bike did he use the most? Is it Agito?

I'm leaning towards Agito if only because he also used it in Kamen Rider Taisen. The shot of him, Tajador and Rocket Module Fourze flying up is... mwah. Just so memorable to me.

Hey is Kamihoriuchi Kazuya (is that the proper syntax for his name?) still doing stuff with toei or has he moved on to different things?

According to the Japanese Wiki Kamihoriuchi is still working with Toei and Tv-Asahi directing the 3rd season of Prosecutor 9 a detective drama show.

I checked the cast and wow, Shinji's boss Daisuke from Kamen Rider Ryuki, Joe Gibken/Gokai Blue from Goakiger and Ui's dad/Seto from Ryusoulger are in it as detectives, and the prime minister from Ryusoulger episode 13 is the protagonist's little sister.

I'd love for him to be teamed up with any Rider that has belts that talk in Broken English and just be correcting it the entire time lol.

Hey do you think Nazca/ Sudo Kirihiko would've got a V-Cinema had double got a third one? What do you think it would've been like?

I'm fine with how they finished his story in the show but now that you bring it up Kamen Rider Nazca would have been cool. A missed opportunity indeed. And what about Kamen Rider Smilodon? Would have made Mick the first ever feline Kamen Rider. :lolol
But jokes aside sucks Kamen Rider Nazca is not a thing. I still would have liked to see it even if it probably would be a retooled spare Double or Accel suit.

So, when I watched the Ryuki Special: 13 Riders, there's something that bothered me.

During the big climactic battle scene, there's a scene when the spider monster (Mispider) appeared out of nowhere and captured Gai with a string shot. As it pulled Gai, a calm female voice can be heard saying, "Let go."

.....who the hell was that?

The only female character present in the scene was Femme, but it's clearly not her voice nor that it'd makes sense for her to say that considering the circumstances. So yeah, it's a mystery to me.

I just went and watched the scene, and it seems pretty clear to me it's Gai's voice. If it sounded a little more high-pitched than usual, it might have something to do with the fact he's being strangled. It's less "calm" and more "barely able to get the words out".
