We see a large collection of the same flowers, one dropping outward, in a large vase behind Yang, now in a short white dress with black heels as she stands at a podium. The doors in front of her open and she flips out upon seeing who walks in.
Yang: "Ooohh, you look beautiful!"
Ruby: (groans as she looks distressed in her red dress with black lace, belt, and pumps) "Can we have a serious talk about how Weiss fights in these?" (tries to maintain her balance as she walks to the podium, much to her laughing sister's amusement)
Meanwhile, outside, Sun is seen walking around and wearing a new black jacket (now closed up) with a white tie hung around his neck, which he proceeds to fight with before going inside.
Sun: "Stupid...dumb...neck trap!"
Blake: (off-screen) "I knew you'd look better in a tie."
Sun stops his struggling and stares at the dark purple dress worn by Blake, now looking like she traded her dark bags for violet eyeshadow, as she steps forward and takes him by the arm.
Sun: "Sooo, does this mean we're going...together? Or are you going with your boyfriend?"
Blake: "Technically, though my first dance is spoken for...by Nick. But...he said he wouldn't mind if I gave you one dance with me."
Sun: "He really doesn't mind you dancing with someone else?"
Blake: "Nick, literally, has seven dates to this dance. Me being one of them. He's going to be busy all night. And he, clearly, doesn't seem to get bothered by me or any of the other girls in his harem being around other boys. It's not like me or the other girls would ever cheat on him. Me giving you at least one dance was his idea, after all."
Inside the ballroom, streamers are hung through glass chandeliers, pink and blue balloons are everywhere, and students in dark suits and bright dresses are stepping with each other to the music between the white-clothed tables. Blake is spun around by Yang before they curtsey to one another, and Sun comes up and takes his "date's" hands as Yang gestures for him to do so. She goes to hang with Nick, wearing a fancy outfit, Ruby, Weiss (in a similar white dress as Yang's), Amber, Erza and Atalanta (who are also in pretty dresses) in the back of the room, watching Blake laugh and enjoy herself before smiling at her team.
Nick: "I told you she would come."
Weiss: "Mission accomplished."
Amber: "But...aren't bothered by her dancing with Monkey Boy over there, Nick?"
Nick: "Nah...I told her that I'm cool with her giving Wukong at least one dance tonight. And I'm not going to be the type of guy who'd get upset at his girlfriends hanging out with other boys. Or dancing with other boys. I know none of you would try to cheat on me. I trust you girls."
Erza: (impressed by her shared lover) "That's very admirable, Darling. And that loyalty and trust will never be betrayed by any of us seven."
Ruby: "Soooo, what do we do now?"
Yang: "Just have fun!"
Yang then proceeds to walk away and do so, with Weiss, Amber, Erza and Atalanta going in different directions and leaving both Nick and Ruby behind.
Ruby: (shouts towards Yang) "Does that mean I can change out of these stupid things and into my hood now? (upon receiving no answer, she waddles around in her painful footwear) Stupid lady stilts!"
Nick: "Yeah...I'm not really into these fancy clothes myself...I can barely move in this."
Ozpin: "Not enjoying yourselves?"
Ruby: (surprised to see the headmaster step up by their side, but shakes her head and laughs) "Oh, no, everything's fine! I'm just not much of a fancy pantsy...dancey girl."
Nick: "Yeah...the same goes for me being more of a guy who prefers to wear clothes I'm more comfortable in."
Ozpin: "Well, you can't spend your whole life on the battlefield, even if you may want to."
Ruby: (crossing her arms, looking annoyed) "Yeah, that lesson's been floating around a lot lately."
Nick: "No kidding."
Ozpin: (stares out at the dancing couples) "If you two think about it, fighting and dancing aren't so different. Two partners interlocked, although one wrong move on the ballroom merely leads to a swollen foot."
Ruby: (looks down at her own feet) "Or a twisted ankle."
Ozpin: "It's not every day that friends are able to come together like this. Time has a way of testing our bonds, but it's nights like these that can help keep them stronger than ever. Nights like these are ones we'll never forget."
Ruby smiles at the words of wisdom, but turns her head at the sound of the doors opening. Yang is back behind the podium, and smiles at the new arrivals.
Yang: "You guys are just in time!"
We see that the people Yang is greeting is Cinder, Emerald, Mercury, and a girl with half-pink, half-brown hair, who's name is Neo, as the four step in with their ballroom best on.
Cinder: (warmly smiles at Yang) "Wouldn't miss it for the world."
Time Skip...
We see random students schmoozing at the dance. Oobleck is shown to be listening intently as Port laughs over some unheard anecdote. Ozpin is standing off to the side with Glynda until General Ironwood offers his hand for her to dance with him. Jaune approaches Nick and Ruby, who are standing pensively near the refreshments tables.
Jaune: "I see you're both hiding at the punch bowl too."
Ruby: "Yep." (An audible *pop* can be heard as Ruby emphasizes the "p".)
Jaune: "To the socially awkward."
Nick: "Even I'm one, myself, sometimes."
Ruby giggles and the three clink glasses.
Nick: "So...couldn't get a date, Jaune?"
Jaune: "No, I do have one. She's just a little late is all."
Ruby: "Really? Who is it?"
Nick: "I get the feeling it's a certain...red-haired spartan, with green eyes?"
Jaune: "Y-Yeah...it's Pyrrha."
Nick: (smirks) "Did you two make out yet."
Jaune: (caught off guard) "W-What?! H-How'd you know that?!"
Nick: (chuckles) "It was just a lucky guess. But I did know you two were head-over-heels for each other. So, congratulations on getting a girlfriend, dude."
Jaune: (rubs the back of his head) "Thanks, man."
Jaune then looks to see Pyrrha enter the ballroom, wearing a red dress.
Jaune: "Looks like my date's finally here. I'll see you guys later."
Short Time Skip...
The scene shifts to show Yang leaning on a handrail and overlooking the festivities from a second tier as Ruby approaches and leans on the rail.
Yang: "You know? I think we really needed this."
Nick and Erza are slow dancing while Lie Ren and Nora Valkyrie appear to be Waltzing. Penny Polendina is shown to be dancing alone, guarded by two Atlas Soldiers.
Ruby: "Yeah, and you did a great job planning it too!"
Yang: (reaches over to Ruby) "Aw, thanks! (crushes Ruby in a one-arm hug as she flails frantically) It wasn't all me, though. Weiss did a lot too."
Ruby stops struggling and looks down at Weiss. Neptune approaches and rubs his neck nervously. Weiss invites him to sit with her.
Yang: (chuffs) "Tomorrow it's back to work."
Ruby: "I'm sure we can handle whatever gets thrown at us."
Nora grabs Ren and drags him out onto the dance floor with Pyrrha and Jaune. JNPR performs a short but elaborately choreographed dance, culminating in Jaune spinning Pyrrha.
Pyrrha: "I had no idea you were a good dancer."
Jaune: "Yeah, well, these things tend to happen when you grow up with seven sisters."
Jaune dips Pyrrha and then spins her away.
Neptune and Weiss are shown to be watching the dancers.
Weiss: "So, are you taking a break?"
Neptune: "Yeah. There are a lot of pretty girls here."
Weiss: "You know that me and six others are already dating Nick, right?"
Neptune: "Yeah, I know, Erza told me. Dude's quite popular, huh? Is he...okay with Blake dancing with Sun?"
Weiss: "Nick isn't the type of guy who'd get mad at his girlfriends hanging out with other boys. And he actually suggested it to Blake that she gave Sun at least one dance."
Jaune and Pyrrha continue to dance. Ren and Nora do a kind of disco dance, Sun and Blake join the mix and Penny and an Atlas guard are showing doing the "robot". Meanwhile, Cinder, Emerald, Mercury and Neo are shown to be observing the students from the next tier.
Emerald: "It appears all the dancers have partners."
Cinder: "It truly is a lovely evening."
Mercury: "You girls know I'm just here for the food."
Emerald: "Whatever, Merc. So...are we just going to stand here, or are we going to enjoy the night?"
Cinder: "I say we enjoy the night."
Nick and Ruby, having made their way to the exit, walks out of the dance and into the night air. They watch as two figures run along the rooftops and then move to pursue. Outside the Cross Continental Transmit System Tower, the two figures (dressed as a cat burglar, but one wearing a red spider mask, and the other wearing a white spider mask), stealthily approaches an armed guard. One of the figures knife-hands the back of his head, rendering him unconscious with a stunned grin on his face. They drag him behind some bushes. Inside the building, the figures approach more guards.
Atlas Soldier 1: "Excuse me, no one's allowed in this area. (the figures continue to approach) Stop!"
The soldier opens fire when figures do not heed him. The one with the white spider mask charges in and manages to overpower him, punching the soldier then grabbing his arm. The figure with the red spider mask 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 them wielding batons. The Red Spider figure 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 the two figures waiting. One of the guards notices the fallen men outside. Both guards grow apprehensive as the figures casually walks onto the elevator, the doors closing as they turn around. Thrashing sounds can be heard from outside the elevator. Outside the building, Nick and Ruby approach and see the unconscious guard. Ruby gasps and pulls out her Scroll, dialing for her weapon locker which crashes into the courtyard and opens to reveal Crescent Rose. Inside the building, the elevator doors open to show the White Spider figure examining a Scroll. The two guards are knocked out. She pockets the Scroll and walks out of the elevator and toward the control consoles nearby. Random code appearing on a computer screen is shown to change into a Queen chess piece, as the other monitors in the room light up. The White Spider Figure looks at her partner as they both nod. As they starts to walk away, they notice the elevator doors opening. Nick and Ruby step out of the elevator slowly, with Ruby brandishing her weapon.
Ruby: "Hello? (She stumbles due to her high-heeled shoes.) Is anyone there? Hello?"
The two figures then rise from their hiding places and steps out toward the couple.
Nick: "Excuse me? You know, it's not a masquerade party, so why don't you take off that-!"
Then two figures then pull out small, strange, box-like items, and hold them in their left-hands. The person with the red spider mask's box is red, with a gold spider emblem on it, while the person with the white spider mask's box is white, also with a gold spider emblem on it. Nick is completely shocked, as he recognizes the two boxes.
Nick: "Hang on! Are those-?"
Silver belts then appear on the figures' waists, as they then slide their boxes into the belts. The figure are then surrounded by energy rings of their respective colors, which then split in two and circle around them before disappearing, as the two figures are now...transformed...into...
Ruby: "Um...Nick? Did they just...?"
Nick: "They turned into Kamen Riders?!"
Yes...both figures transformed into Kamen Riders. Both with a spider theme on their suits. Nick then pulls out his own box, his being red, with a gold Dragon Emblem on it, as a silver belt appears on his waist.
Nick: "Kamen Rider!"
Nick then slides the box into the belt, as a red energy ring rotates around him, before disappearing, with Nick now transformed into Kamen Rider Ryuki (But we'll call him Kamen Rider Dragon Knight). The two Spider Kamen Riders seem shocked by Nick's transformation, as the Red Spider Kamen Rider fights Dragon Knight, while the White Spider Kamen Rider fights Ruby. The two Spider Kamen Riders eventually jump into monitors, as if they were portals, escaping Dragon Knight and Ruby. The camera pans away from the two showing the rest of the party. Jaune and Pyrrha are sitting at a table, Yang and Blake are dancing, there is a squad of red and yellow soldiers outside and Ironwood is shown approaching Nick and Ruby before one last shot of the Queen chess piece appears on the computer screen and the clock chimes midnight.
