The World of Remnant... A place containing peace... And ruin... Grimm and Demons cause chaos wherever they strike. But how does one fight Demons? With t...
We open in the Happy Spa where you try to relax in a bath but what Kagero said during your last encounter.
Y/N: Vice... Is it really that much of a problem? My nosiness?
Vice appears beside you.
Vice: Nah. It's just who you are. You shouldn't let that bother you.
You lean back and look at the ceiling in thought.
Vice: Emi is supposed to be working with Ruby and the others to save August. What are you going to do?
Y/N: ... I'm not sure...
Meanwhile, Kagero opens the door to a warehouse where he has three people tied up.
Hostage 1: Let us go!
Kagero grabs her by the collar and smirks.
Kagero: Not until I'm done using you fools to make Deadmans.
The door is kicked open to reveal Daniel and a group of Fenix troopers.
Daniel: Kagero! Surrender!
Kagero: So... You found this place...
He holds up the Brachio Vistamp and presses its button.
Brachio!
The Demon proceeds to stamp the three hostages and creates new Brachio Deadmans.
Daniel: Henshin!
Spider! Decide Up! (Kamen) Rider Demons!
Daniel runs at the Deadmans while his troops rescue the hostages. The three Deadmans try to overwhelm the Spider based Rider but team RWBY comes in and start attacking the Demons.
Ruby: August! We're going to bring you home!
Kagero: How many times do I have to repeat myself? August is no longer in control.
Yang: Then we'll have to knock YOU out of control!
Kagero: Come at me then...
Bat! Confirmed!
Kagero: Henshin...
Versus Up! Kamen Rider Evil!
Kagero rushes at the girls but Weiss blocks his blade with her rapier.
Weiss: Ruby and I will handle Kagero. Blake, Yang, go help Daniel!
Yang: Got it!
The two girl charge at the Brachio Deadmans. Kagero breaks the blade lock with Weiss and tries to punch her only for Ruby to shoot at him with her scythe.
Evil: Where's August's siblings?
Ruby: What? Afraid a bunch of girls will beat you?
Evil: Hardly. I'm just wondering if I should slaughter you all in front of him or not.
Daniel punches one of the Deadmans while Blake and Yang strike the monsters with their respective weapons.
Yang: Booyah!
The three Deadmans roar and merge into a single form.
