Weiss has joined Vice and your siblings in seeing George. The scientist examines the Vistamp you were given and grunts.

George: Someone messed with my Rider System... This isn't my design.

Vice: Huh?!

Weiss: What about Y/N?

George: It seems as if Y/N and Vice have swapped places.

Vice hold up your Gundephone and you appear on the screen.

Emily: Y/N!

August: Sir, can you fix this?

George: I should be able to. Though it might take a few hours. Maybe a day. Until then, keep Vice out of trouble.

Weiss: Right.

The four leave and Vice stretches.

Vice: Man, this has been crazy!

Weiss: Are you doing alright, Y/N?

You appear on the Gundephone again.

Y/N: Yeah. Just trying to adjust to this situation.

Emily: How did you and Vice swap in the first place?

Y/N: No idea. But it did have something to do with that Vistamp.

Vice: ... I'm not sure about trusting George... He might try to experiment on us...

Y/N: If you can't trust him, then trust me.

Vice: Alright.

Y/N: So... What do we do until we get back to normal?

Vice starts to laugh.

Vice: I have some ideas...

We immediately cut to Vice at an arcade, playing a drumming rhythm game while Weiss stares in confusion.

Vice: Hell yeah! New high score! Huh? Where'd August and Emily go?

Weiss: They had to take care of some things.

Down in Mantle, August and Emily were patrolling to make sure there isn't any trouble. August looks at a poster of a woman with the text; Vote Robyn Hill for the Council Seat.

Emily: Robyn Hill?

August: She fights for equality between Atlas and Mantle. I heard about her before we left for Haven.

Olteca: Quite the individual.

The L/N siblings turn to see Olteca.

August: Olteca...

Emily: You greasy rat!

She puts on her Driver.

Emily: You're gonna pay for what you did to Daniel!

August: Right behind you.

Bat!
Cobra!

Confirmed!

Olteca smirks and holds up the Spider Vistamp.

Olteca: Come at me then...

Spider!

Deal...

All 3: Henshin!

Versus Up! Kamen Rider Live!

Liberal Up! Kamen Rider J-J-J-Jeanne!

Decide Up! Kamen! (Rider) Demons!

August and Emily rush at Olteca as he counters their attacks. He punches August in the head and knocks him back with a kick, de-transforming him, before kneeing Emily in the stomach.

Jeanne: Gah!

Lovekov: Lov! Lov!

Olteca throws Emily at Lovekov and the plush-like Demon cushions her impact.

Demons: I think I use this power in a far more productive way than your dear friend.

Olteca launches an energy spider at Emily but August suddenly jumps in front of the attack and switches the TwoSiDriver into blade mode.

August?: Oi... You aren't killing her. She makes pretty good curry...

Emily: Kagero?

Kagero: Henshin...

Versus Up! Kamen Rider Evil!

Olteca: Aren't you a pest...

Add!

Batta!
Scorpion!

Dominate Up!

Olteca activates a double Genomix and jumps up to perform a finisher.

Evil: Tch... August, you owe me for this one...

Hissatsu Shonin!

Batta! Scorpion! Demons Requiem!

Bat! Darkness Finish!

The two attacks collide and actually knocks Olteca back while Kagero is knocked out of his transformation, giving August control once more.

Olteca: Tch...

The cultist vanishes as August looks in shock.

August: Kagero... Helped us?

Meanwhile, Vice was now playing a dancing game at the arcade and Weiss looks at the people staring in concern.

Vice: And that's the high score on everything in here! #NiceVice!

Weiss: Y/N... I just thought of something. What if you get hungry?

Y/N: Oh yeah...

Vice: Oh no!!! I forgot! Since I'm a Demon, I don't really need to eat but Y/N does! If we don't switch back, he'll eventually starve, which means we'll both die!

Your Gundephone rings and Vice answers it.

Vice: Hello~?

August: Vice, Y/N, be careful. We had a run in with Olteca.

Vice: Huh?! Why's he in Solitas?!

August: I don't know, but we're going to warn General Ironwood now. Be careful.

Y/N: We need to go see if George has made any headway.

Your group returns to George who has been studying the Rolling Vistamp.

George: This Vistamp is something else...

Vice: Georgie! Olteca's in Mantle!

George: What?!

Meanwhile...

Olteca arrives in an abandoned building, where two familiar villains are waiting...

Cinder: And where were you?

Olteca: Out on a stroll. Why? You wanted company who actually talks to you?

He looks at Neo, who glares at him.

Cinder: If you make a scene, it will make it harder to take the Relics and the Winter Maiden's power.

Olteca: Please, I couldn't care less about either of those.

Cinder grits her teeth.

Cinder: What?

Olteca: I don't give a damn about your little sob story or Salem's goals. I only do something if it benefits me.

Neo goes for her parasol but Olteca holds up the Demons Driver.

Olteca: Control your pet mute or I'll kill you both. I only came with you to Atlas to get to Giff's casket. So don't try to boss me around.

The screen of the Demons Driver lights up as purple eyes appear on it.

????: Calm yourself, Olteca. They're still useful.

Olteca: How?

????: They can help us unlock our full power...

Cinder: And why would we?

????: A deal... You bring us George Goldenrod, and we'll help you get to the Winter Maiden...

Cinder: ... Fine...

????: Excellent... Hehehehehe...
