I’d imagine while Shoma & Hanto had surgery, why not Sachika as the potential third rider, she’ll go through a blood transfusion.

Given the chocolate icing on his donut-and-sprinkles form, Valen continues to be, at least initially, a chocolate-themed Rider. As such, I suspect we'll see a Valen edgelord or evil-version plot wholly so we'll be introduced to a Dark Chocolate super-form.

I'd love to see dark chocolate representation, but I think it should be good, not evil. After all, dark is the purest flavor of chocolate, so it should emphasize Hanto's passion for justice.

Since Gavv is a cake in the upgrade, what'll be his super form & final form?

May I ask where you heard this from?

As for final form, knowing Reiwa trends it would most likely just be a gummy. I would love to see a jello-based super form though.

For some reason I actually wouldn't mind a Popping Gummy repaint much like Cross Saber as a final form. If they can offer us something even better when it's time, great, but I won't complain if they repaint it as long as it fits well with the story.

Watch Shouma's berserk form be the result of him eating a Dark Treat.

CaKing form, armed with the GavvWhipper!

The rumors were true?

I...actually like this! It seemes that the GavvWhipper holds six cake Gochizos, and Gsvv transforms with a 'slice' of the cake? That's ingenious.

I dig this upgrade form!
