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?
