Gear Remnant (Kamen Rider OC X RWBY crossover)

Infiltration

At the ballroom, everyone was dancing and have a good time.

Mercury Black and Emerald Sustrai are shown to be observing the students from the next tier.

Emerald: It appears all the dancers have partners.

Cinder: (heard via ear-bud) How long do I have?

Mercury: You should probably be home by midnight, to be safe.

Cinder Fall is shown to be somewhere outside, holding her fingers to her ear.

Cinder: I'll keep my eye on the clock.

A mysterious man in white suit appear far behind Cinder and saw her go outside of the ballroom. He watches the figure running along the rooftops and then moves to pursue.

Ellipse: I found you.

Outside the Cross Continental Transmit System Tower, Cinder, stealthily approaches an armed guard. She knife-hands the back of his head, rendering him unconscious with a stunned grin on his face. She drags him behind some bushes.

Inside the building, Cinder approaches more guards.

Atlas Soldier 1: Excuse me, no one's allowed in this area. (Cinder continues to approach.) Stop!

The soldier opens fire when Cinder does not heed him. She charges in and manages to overpower him, punching the soldier then grabbing his arm. Cinder kicks another soldier and uses the first one's gun to take him out. She then kicks the soldier's knee and throws him against a handrail.

Two more soldiers rush her wielding batons. Cinder flash-forges a pair of black blades from fire Dust and slashes at both of them. Batting the first aside she advances on the second and strikes him before sweeping both legs.

The first soldier recovers but she blocks each swing with her blades. After blocking a kick she elbows then shoves him to the floor. As he tries to get back up she flips over to kick him in the head, checking for more guards before moving on.

Two guards are shown to be on an elevator.

Atlas Soldier 2: Hey, man, do you know the Wi-Fi password?

Atlas Soldier 3: It's Beacon, but replace the E with a 3 and add a pound symbol to the end.

The elevator door opens to show Cinder waiting. One of the guards notices the fallen men outside. Both guards grow apprehensive as Cinder casually walks onto the elevator, the doors closing as she turns around. Thrashing sounds can be heard from outside the elevator.

Outside the building, Ellipse approaches and sees the unconscious guard. He looks up the tower for a few seconds.

Inside the building, the elevator doors open to show Cinder examining a Scroll. The two guards are knocked out.

Cinder: Oh! That's handy.

She pockets the Scroll and walks out of the elevator and toward the control consoles nearby.

Emerald: (via earbud) A party guest is leaving.

Cinder: (sighs) Which one?

Emerald is shown to be dancing with Mercury.

Emerald: Ironwood.

Ironwood is shown to be walking out the door as Ozpin gives his send-off.

Mercury: (offscreen) I guess the general's had enough fun for one night.

Random code appearing on a computer screen is shown to change into a Queen chess piece.

Mercury: (via earbud) Should we intervene?

The other monitors in the room light up.

Cinder: No... we're done here.

As she starts to walk away, she a footsteps coming somewhere in the room. Ellipse coming out from the corner of the room.

Ellipse: Come out, Cinderella. I know you're here.

Cinder was shocked when he know her real name. Cinder try to regain her confidence and then rises from her hiding place and steps out toward Ellipse.

Ellipse: No need to be hostile toward me, young lady. Tell me what are you doing here?

Cinder produces a container of dust from her belt expelling a cloud that glows. Condensing into glass shards that go flying at Ellipse. Ellipse react quickly and grab those glass shards on his hands and drop it on the floor. Cinder was shocked.

Ellipse: You can't kill me, Cinderella. I am untouchable.

Cinder girt her teeth and summon her two blades on her hands and charged towards him. She slash her fire blade at him but he avoids it and kick her into mid-air. She combined her two blades into a bow and fires three arrows. Ellipse avoid it and the three arrows hit on the floor and cause it to explode. Ellipse stumbles back from the resulting explosion and they stare each other down.

Ellipse: Cinderella, it over already. The General will arrive any minute.

Before Cinder can said anything to him, their fight is interrupted by the appearance of Ironwood on the nearby elevator.

Ellipse: General! I'm glad you came in the right time. I just caught the thief who broke in this tower.......?

He turn around and saw Cinder disappeared in the room.
___________________________________________

In a hallway, Cinder discards two bracelets and her mask to change from her stealth suit into a black dress and enters the dance. Two guards following her crush the bracelets underfoot and are visibly confused at the sight of the crowded dance hall.

Emerald and Mercury are still dancing together as Cinder taps Emerald's shoulder.

Cinder: Oh, may I cut in?

Emerald steps aside.

Emerald: Of course.

Emerald leaves as Cinder begins to dance with Mercury.

Mercury: And how's your night been?

Cinder: Mmm... a little less exciting than expected.

Mercury: Should we be worried?

Cinder: Yes.

Mercury: What do you mean "yes"?

Cinder: I don't want to tell you about that.

Emerald: But, Cinder. Aren't we a team? You should tell us what happened at the tower.

Cinder: No need to worried about me. Now, let just focus on our mission and focus on the invincible girl and the knight boy.

Mercury: So then what now?

Cinder: Enjoy the rest of the night. After all, it is a party.
