So I have a theory. A "leaked" picture surfaced a little while back of one of the Riders (I honestly can't remember who) fighting the Planaria Deadman. If the picture is indeed some form of a leak, and the Planaria Deadman does come back, it's given rise to two theories in my mind.

Theory one! We never saw the stamps for the Gifu sacrifices being destroyed. So it leaves the possibility of new bearers picking them up.

Theory two! When the Phase 3 Deadman's were defeated they turned into particles and those particles entered the Gifu Statue/Coffin (save Julio and Olteca who were separated). The Statue/Coffin is now emitting particles. What if those previously defeated P3 Deadman could be reformed/resurrected when Gifu is released/summoned?

Just my thoughts on the scenario.

I say it holds weight.

He could use Heisei or Showa, or like you suggested before, he could use White Leo and Quetzalcoatlus.

I hope that doesn't have to happen, but if it did, hypothetically, I could imagine it the other way around, with Sakura sacrificing herself and Aguilera becoming the second Jeanne with her motivation to start her new life outside of Deadmans.

Awesome typo.

The advantage of having less Riders is that the characters get more focus and development like in Build and Zi-O. Still hoping George gets to become a Rider though.

I'm most definitely on team "We don't need more Riders". Reiwa has had an issue with getting a bit overloaded with too many Riders so a lot of then end up never getting much focus, while in Revice, everyone but poor forgotten Kagero gets their turn in the spotlight regularly

I wonder if we'll ever see a main villain who isn't a rider in Reiwa.

I get the feeling Demons was supposed to be the new rider if it weren't for the behind-the-scenes reshuffling

Well, I'm at least not expecting "Kamen Rider Giff" to happen once he's released. Then again, I wasn't expecting them to turn Storius into a Rider either...
That would make a lot of sense. Demons has the most villainous name of the Riders (aside from "Evil"), usually by this point we have a new Rider who shakes up the plot somehow, if you take Hiromi out of the equation Olteca's fight with the Igarashi's could easily have been a classic villain Rider debut where they first show up and wreck everybody.

Jeanne's the official tertiary Rider so Demons was always kind of an odd duck among the initial Riders because of the Hiromi situation.

I liked Hiromi but many of his fight scene's felt like add-ons. He would be off fighting grunts while the siblings were dealing with the main villain of the episode. I wouldn't be surprised if suddenly Demons receives much more screen time

White Leo & Quetzalcoatlus depends. That goes for the possible "Hammerhead" & "Elephant".

As for Sakura sacrificing herself for Aguilera so that she be the new Jeanne? I dunno. Either that or Aguilera gives her Vistamp to Sakura as her final gift for thanks. I'm really scared. I want them both together. Oh I feel so conflicted!

I had the crazy idea, their Dad was an ex-cultist for a while.
