I'd be fine with this. Zi-O is still very recent.

Would you all want to have KR Shinobi an official Reiwa rider or have someone new replace him as the new rider? As long as he can take up the ninja theme.

Yeah, I meant to say Zi-O instead of Decade. I don't think Decade had much Legend Rider cameos, was more focused on the AR Riders

Would you all want to see Shinobi become officially Reiwa's next rider after Revice? Or have an original rider be made with or without the ninja theme?

No need to repeat it, but at least having a ninja themed season would be fine to me

When Revice gets an upgrade, what kind of new weapon would you picture them gaining? Vice will probably wield the Ohinbuster 50, but what of Revi? A sword?

Saber: Dragonic Knight (as Kaenken Rekka is part of Saber)
Zero-One: Shining (Assault) Hopper + Authorize Buster and later Metal Cluster Hopper + Progrise Hopper Blade

What kind of demon do you all see in Daiji’s like? Vice is the new “Momotaros” with a touch of Deadpool.

Someone like….
Urataros, Kintaros, Ryutaros, Deneb or Sieg?

Personally, I’d say an anti-Deneb.

Either an anti-Vice or Desast 2.0.

If I recall correctly, in Den-O, Momotaros was often 4th wall breaking in his behavior right?

It's been a while since I've watched Den-O, but in the Heisei Generation Forever movie, he makes a meta-contextual joke about being "overpowered".

My guess it’s either going to be themed around jealousy towards Ikki or self-doubt.
