That would be an interesting take, actually, to have Evil be, well, evil throughout most of the season. But I feel like it won't take long (Give or take episode 20) for Kagerou to be tamed. Or probably getting tamed during an upgradedebut.

Zi-O/Brachiosaurus Genome looks great! Already one of my favorite Genome forms, Gaim/Mantis looks good, too.

I can see how Live looks too different from Evil, but the colors between the two is kind of genius, where Evil is black, Live is white, which fits for a member of FENIX. Also, his design reminds me of Ryuki, or one of those Riders, still like the design.

And Demons gets Showa Riders in line with Ultraman Victory's gimmick, that or Beast from Wizard.

Overall, loving how Revice is looking.

One thing I didn't comment on though, Zi-O Brachio is looking good. Might just be my favorite Genome out of all of them.

Well, I might be on hiatus with rider this season, but I love how:

Demons looks like a cross between Genm, Drake, and Meteor
Live reminds me of Bima The Garuda Knight, IXA, and Ghost

Someone on YouTube commented that Live resembled Den-O Wing Form, and I find that quite accurate. Both of them reflected more of an angelic look rather than a demonic look.

And now Evil moved on from using a stupid looking blade to a stupid looking gun. Seriously I love Revice's suit designs but the weapons (aside from the gunphone and Ohinbuster) look rather awkward to use

Considering the Twosidriver literally goes "Eeny! Meeny! Miney! Moe!", I wouldn't be surprised if Daiji transforming into Live or Evil is just a random crapshoot. That way it leaves a risk of letting Kagero take over his body when he doesn't want to.

Not to mention that it also says "Versus Up". Definitely would not be surprised (and would absolutely love it) if they kept the split personality thing going for a good while.

Also, I feel like I called that the Kamakiri Vistamp would reference "Hanamichi on Stage".
Though, I think that the Zi-O Brachi-O Vistamp would reference "Rider Time!"

And I think that Kamen Rider Revi Kamakiri Genome looks more like Jimber Arms instead of Orange Arms (it's more Boxy than Orange Arms, yet the right amount of Boxy-ness for Jimber Arms). Which would make sense considering that he wields a Sonic Arrow-based Weapon.

Also, the fact that the Magazine Scans show Revice Brachio Genomes alongside Kamen Rider Live makes me feel like my observation that Daiji's Relationship to Kagero is similar to Sougo's relationship to his mirror-world Self might be accurate.
Now, going into speculation mode, I feel like Daiji and Kagero might have made up their differences and that Daiji might have more control over Kagero or, possibly, he realized that Kagero represented his inner resentment for Ikki. So, I think that Kagero and Daiji could be able to swap control over their body, sort of like Den-O, which Kamen Rider Live resembles Den-O Wing Form. And it would be symbolized by which mode the Evilblade is in. When the Evilblade is in Sword Mode, it's Kagero's Turn. When the Evilblade is in Gun Mode, it's Daiji's Turn. I think that both of them will have their own strengths and weaknesses, so, depending on the situation, Evil could be better suited.
Also, realize that the Driver is called the "Twosidriver". Like "Two sides of the Same Coin".

Also, I was listening to the Transformation Jingle for Kamakiri Genome here:

and have noticed that the Jingle for Kamakiri Genome has a Japanese Feel. Do the rest of the Jingles resemble music similar to the Rider's Series?

How would you imagine Brachio Genome's jingle from Zi-O?

Perhaps "I want to become a King!", "I will become the demon king! However, I won't be the villainous demon king. I will be the greatest, kindest demon king!" or "I've got a feeling this will work out!"?
