What's up, everyone! GKC here and this is an opening them for the first arc of Digital Synchronization. Since this is a crossover of Digimon and 5D's, I'm thinking of going with themes that suit the story. Quick note: This is only for fun. It's not a chapter.
(Cue ODD FUTURE by UVERworld)
The screen opens to a camera zooming out from the lens eye of Kamen Rider Kurenai who is postured in a crouch as if waiting to pounce.
(I keep my ideals Sorezore no tenmei wo)
A brief cut of the title "Remnant's Climax Heroes" appears before vanishing, leaving a silhouette of Kurenai in the center as cutaways detailing the adventures of the Rider as well as his teammates and friends before the camera zooms in as Kurenai lunges forward.
(What's going through?)
A brief cutaway featuring Ozpin facing off against Salem appears before vanishing in a bright light.
(Subeta wa mi kara deta sabi)
The scene transitions to Team JOKR preparing their weapons and readying themselves for the Vytal Festival.
(Haburi yoku fuyashita kurorekishi)
The four Riders then appear in the stadium filled with numerous viewers watching them with cheers.
(Ari to arayuru mono wa sutetari)
Team RWBY, JNPR, CFVY, and SSSN stand with the Riders while MMYYR watches their friends and family from the audience chairs.
(Mi ni oboe no nai unmei ni)
Professor Port and Doctor Oobleck are commentating while Aaron slams his fist into his palm in anticipation.
(Korosarekaketa koto mo atta shi)
Cuts to an image of the rival Teams for Vytal Festival, who all seem equally eager to face off against the Riders and their allies.
(Shinda me wo shite ikita jiki)
Cuts to General Ironwood and Winter Schnee walking through a corridor while Atlas soldiers salute them.
(Soredemo kyou mo ikasareteru tte koto wa)
The screen cuts to Azrael, Team ROGE, Cinder, Mercury, and Emerald surrounded by red flames before Neo appears in front of the group with a playful smirk then she swipes her umbrella at the camera.
(What's going on? Mada sou yarinokoshiten darou)
Cuts to Orpheus opening his eyes while across from him is Pyrrha, who is having an emotional breakdown while a girl in a pod fades in front of her.
(Shuusei no shiyou no nai hibi No naka demo)
The scene shifts to Aaron walking through a rainstorm with his hair shadowing his eyes while a dark armored figure with glowing red eyes appears behind him.
(What's going on? Hito to wa chigau to mito meta ue de)
Cuts to Orpheus with his Lyrical Relevance pulled back as he fires a several light arrows at an opponent before Kurogasa dashes in at sonic speed with his Kage Ryuujin held in an iaijutsu stance then Orion appears with Lunar Divide held with one hand as he stabs the weapon down with enough force to shatter rock.
(Kanousei no rutsubo hiraku ah~)
Cuts back to Aaron in the rainstorm as he lifts his head up glaring at the camera before he grabs onto the left gauntlet of Blood Moon as crimson electricity streaks across it.
(Dreaming ishi gyakusou)
The scene transitions to Beacon Academy looking peaceful before it suddenly shifts to it being engulfed in flame as Grimm and Kaijin attack the school.
(Shikakui sora kokoro no sukima umenu)
The camera pans over to Azrael with his hood down and a wicked grin on his face as he watches the destruction while Team ROGE stand behind him in their Alter Forms before he throws a ball of dark energy at the gate.
(Akenu yoru kara nukeyou)
The gate explodes but from out of the smoke Team JOKR, RWBY, JNPR, CFVY, SSSN, and MMYYR jump out with their weapons ready to fight and defend their school.
(Mirai no kaizou do sage bokura wa)
The heroes and villains charge at each other. Koa lands in the center, facing off against her former creator with a Driver on her waist then she transforms into her Kamen Rider form.
(Me wo sorashite wa naritai)
Azrael is engulfed in darkness before a dark armored warrior with red eyes is left in his place as he lunged at Koa only to be intercepted by Kamen Rider Kurenai in his Exceed Burst Form.
(Mono nante nai to usobu ita hibi wo)
Kurenai throws a punch as crimson electricity streaks off his arm then goes to his helmet, which slowly shatters slowly into pieces until only Aaron's enraged face is left.
(I keep my ideals sorezore no jinsei)
Cuts to Cinder standing in the ruins of Ozpin's tower as she unleashes the power of the Fall Maiden with a wicked smile on her face. Cuts to brief scenes of Kamen Rider Luna slashing with her claws, Kamen Rider Orochi flipping in the air, Kamen Rider Hikari throwing a kick, and Kamen Riders Tora and Shadow back-to-back.
(Ai mo yume kiken na hodo)
Cuts to Kamen Rider Shiro slashing with his Ryuukotei, Kamen Rider Azure bracing himself, and Kamen Rider Nero wielding a Feather Kunai.
(Kanta ni hi ga tsuichau no sa)
Finally, Kamen Rider Kurenai performing a Rider Kick on the camera, engulfing it in crimson light.
(Gongu nari sorezore no tenmei wo)
The light reveals the title of the story, "Remnant's Climax Heroes" for the last time.
The final scene of the opening reveals Aaron still clad in his Kurenai armor but his helmet is gone as he stands ready for another fight with Kurogasa, Orion, and Orpheus standing with him also in their Rider armor but their helmets gone.
(End of Opening)
