"Stand aside please!" Sento shouted to the students in the hallway, as he ran down the hall with Banjou, the man who had emerged from the Another Rider carried between the two.

They eventually slowed to a stop as Banjou knocked on the door to the inferary. The door slid to the side, as a man in a white doctor's coat looked out. "Yes? What seems to be the problem... Bring him inside."

The doctor quickly got to work clearing some space to put the man down on, as Sento and Banjou placed the man on an empty table.

"What happened to him?" Asked the doctor, walking up next to the patient.

"We're not sure. One second he was a monster, the next he was like this." Said Sento, putting a hand to his chin.

"Is that so? I'll keep an eye on him for now. If anything comes up, I'll let the two of you know." Said the man, as he turned around, facing Sento.

"Thanks for the help." Said Sento, nodding to the Doctor, as he left with Banjou.

The doctor nodded, before walking over to a closed curtain, opening it up to show a man in strange clothes sitting on a bed, his face staring at a handheld as his fingers mashed on the buttons. "Hey Parado, can you keep an eye on him for a few minutes, I need to speak to Ozpin about something."

The sound of a game being cleared echoed from the handheld, as the man stood up. "I can keep watch." Said the man, dusting his purple pants. "Don't take too long now, Emu."

"Got it!" Emu said, walking out of the inferary, grabbing a red and white stethoscope on his way out.

"...Wonder what might be your deal?" Parado asked, looking at the patient.

It's been a day since the incident with the Another Rider yesterday, and it was about time for combat training. "Today was uneventful…" I muttered, walking out of class for the day, as I walked down to the combat arena.

"Bryce!" I turned my head to the right as Ruby ran towards me. "You're heading over to your combat training, right?'

"...Yeah… Why?" I asked, as giving a look to Ruby, as placed her hands together.

"PLEASE LET ME WATCH!" Ruby begged, causing me to jump back.

"Jesus!" I shouted, letting out a breath as I collected myself. "...Yeah, it should be fine." I said, nodding.

"Alright!" Ruby exclaimed, cheering.

I felt a bead of sweat roll down the side of my head at this. "Right… Oh, we're here."

I walked into the arena with Ruby, watching as Ozpin stood at the centre of the arena. "Ah, Bryce, I see you brought Ruby along with you."

"She was kinda… forceful on her want to watch today's training." I said, crossing my arms as I stood up.

"Well she can sit in the viewing gallery for now. Professor Kiryu is currently working on getting his class in order." Said Ozpin. "We've needed someone who knew physics as well as he did."

"Great… Physics…" I muttered. "Not like I would even understand the basics in the first place."

"With that said, today you'll be training with our backup." Said Ozpin, stepping to the side, as Banjou walked onto the arena floor. "I heard you gained a new power. Why not show me what you're capable of?"

I nodded, rolling my shoulders as I grabbed the ZI-O Ride Watch off the holder, while I pulled the Cross-Z Ride Watch out of my pocket. I twisted both dials before pressing each respective button on the Ride Watches.

{ZI-O!}

{CROSS-Z!}

Banjou smirked. "Well, show me what you got kid!" He shouted, pulling out a red and orange looking device, styled like a knuckle of some kind.

"The Magma Knuckle…" I muttered.

"Your knowledge is starting to freak me out…" Banjou stated. "When this is over you have some explaining to do."

"Was going to explain myself anyways, let's see what you can do!" I shouted, sliding both Ride Watches on their respective slot at the same time, the clock started to tick behind me.

Banjou pulled up a black fullbottle with an orange cap, which he snapped into place before slamming it into the top of the Magma Knuckle.

[BOTTLE BURN!]

Banjou slammed the Knuckle onto his driver, the front opening up to show the bottle lighting up.

[CROSS-Z MAGMA!]

Banjou gripped the handle of his driver as he twisted the lever over and over, before he punched his hand, getting into position. "HENSHIN!" He shouted, throwing his arms to his sides as he tensed for the lava that should've poured onto him.

Key word being should've.

"What the… Why the hell aren't you working!?" Asked Banjou, fiddling with the knuckle. "Dammit, this is just like with Evolto…"

"Try Great Cross-Z." I said, as Banjou looked up. "We've confirmed that one works, right?"

"Yeah." He said, taking the gold Evolbottle out and raised his hand up, the Great Cross-Z Dragon flying into it. Banjou snapped the cap into it's open position, before placing it into the Dragon and pressing the button.

[KAKUSEI!]

Banjou removed the Magma Knuckle out of the Driver, before placing the Great Cross-Z Dragon in it's place.

[GREAT CROSS-Z DRAGON!]

Banjou gripped the Magma knuckle in his left hand, while he gripped the lever of his driver in his right, twisting it around until the driver rang out.

[ARE YOU READY!?]

"Henshin!" Shouted Banjou, as the Great Cross-Z Dragon armour formed around him.

[WAKE UP CROSS-Z! GET GREAT DRAGON! YEAH!]

Banjou switched the Magma Knuckle to his right hand, slamming his open palm into the front of the knuckle.

"Right, the Knuckle may not help you transform, but it still is an excellent weapon." I Said, nodding, before I smirked. "Best get back into the fray then."

I pushed down on the top of the driver, bringing my arms over my head before resting the to the right. "Henshin!" I shouted, backhanding the right slot of the driver, giving it a full rotation as I activated the henshin.

[RIDER TIME!]

{KAMEN RIDER! ZI-O!}

The ZI-O armour quickly formed around my, as the Cross-Z armour formed to my left. I placed my hand against the suit as it quickly split apart and latched onto my form.

[ARMOUR TIME!]

{WAKE UP BURNING! CROSS-Z!}

I rolled my shoulders, slamming my fist into my open palm, mimicking Banjou across from me. "I get the feeling I can't lose!" I shouted, running at him.

"That's my line!" He responded, swinging high at my head with his Magma Knuckle. Time seemed to slow for me, as I tilted to the right, delivering an uppercut to his chin in retaliation.

Banjou stumbled back, before slamming his open palm against the front of the Magma Knuckle, the sound of it charging up growing louder and louder. I quickly pushed down on the buttons on each Ride Watch, before pushing down on the top button of the driver, unlocking it.

{FINISH TIME!}

{CROSS-Z!}

"Good heavens, would you look at the time?" I said, spinning the driver around as blue flames started to form around my arm. "Rider Punch!"

{DRACONIC!}

{TIME BREAK!}

Banjou ran towards me, as he threw his fist, the Magma Knuckle lit ablaze.

[VOLCANIC KNUCKLE!]

Our fists scrapped together, as they slid to the side, closing in on the other's head. It was in that single moment, that Banjou's Magma Knuckle slammed into my face, sending me flying in an explosion of fire and magma.

[ACHA!]

I dropped to the floor, rolling to a stop as my transformation deactivated. I groaned, standing up as I picked up the Ride Watches that had been removed when I was forced out of my transformation. "That… was a ride." I said, walking over to Banjou, as the musclehead let out a sigh, taking out the Great Cross-Z Dragon from his driver.

"You did pretty well." Said Banjou, walking over to me. "Though your hand to hand could use some work."

"Well, I had maybe a week of hand to hand training in general so…" I began, looking to the side.

"Well, then I think I can work something out." Said Ozpin, walking down to the arena. "Up until now, Ryuga Banjou has been working at Beacon under the position of Janitor. The reason for this is because I was unsure if Banjou would be able to teach anything substantial for the students to warrant a teaching position, but this does give an idea…"

"What would you think about teaching the future huntresses and hunters about hand to hand, seeing as most of them are only trained in their own weapon?" Asked Ozpin, looking at Banjou.

"Teaching, huh?" Banjou said, looking to the side. "You know what, sure. Beats janitor work."

The door to the Arena opened up, as Sento walked in, a hand on his chin. "-s that he should have more access to it than he already does." Sento muttered to himself.

"Oi! Sento!" Banjou shouted. "Guess who's not a janitor anymore!"

"They let a musclebrain like you teach classes?" Asked Sento in confusion.

"Oi!" Banjou shouted. "Just because I'm not a narcissistic physicist doesn't mean I can't teach things to people!"

"Professor Banjou will be helping with the sparring class to help with hand to hand. He will also be working as your assistant in your class." Said Ozpin, taking a sip from his cup. There was a ping sound, as Ozpin pulled his scroll out. "If you'll excuse me, the Doctor wishes to have a word with me."

I watched the retreating back of Ozpin, while Sento mulled the words over in his head.

"Assistant huh?" Sento muttered, looking to the side. "Oh right! I've been meaning to ask-"

"Oh, Sento! We need to talk about something first!" Banjou interjected, as Sento turned to his friend.

"If it's about how Bryce knows so much about us I was just about to ask that."

"No- well, yeah, but not that." Banjou said. "It's about Magma."

"What about it?" Sento asked, crossing his arms.

"I can't transform into that form." Said Banjou, crossing his arms. "The Knuckle still works, but only as a weapon."

"...It might have something to do with the Ride Watch." I said, as they looked to me. "Well… Magma was a base Cross-Z form, yeah? It would make sense that when Base Cross-Z's power was sealed in the Cross-Z Ride Watch, that it would lock out the upgrade forms as well."

"...Then I'll have to look into an upgrade for Great Cross-Z then." Said Sento, nodding to himself.

"I mean… there is the Hazard Trigger option." I said, as the two looked at me before shuddering. "Oh right, Blood."

"And he knows about him too!" Banjou said, grabbing my shoulders. "How much do you know!?"

"A lot of it, almost everything. I'm a bit fuzzy on the details surrounding Blood and the other heads of the country when Cross-Z Build was a thing." I said, as Banjou stepped back. "Look, I can explain this later, just… not in a totally open space like this."

"Follow me." Said Sento, walking to the door.

I sighed, looking at the group of Ruby, Banjou and Sento, all sitting with me in what I assumed was their dorm. "Follow me." Said Sento, as he walked over to a… fridge?

"No… You didn't." I said, as Sento opened the fridge door to show a passageway to a lower level. "You did…!"

"After you." Said Sento, as I nodded, ducking through the fridge as I walked to the lower floor.

"Wow…" I said, looking in front of me. It seems in the year they've been here, Sento had reconstructed the hidden underside of the cafe from his world. "Well, I don't see the purification machine here so I guess it's not a 100% match…"

"Right, let's get started, as Sento pulled out a white board from the side and picked up a marker. "Okay! So, we're here, on Remnant. Banjou and I are here, Earth."

"Ooh...! Isn't that where you're from as well, Bryce?" Asked Ruby, looking at me.

"Sort of, make another Earth, no Skywall." I told Sento, as Sento made another round circle, while marking the skywall on his earth.

"As I was saying. Banjou and I arrived one year ago when we merged our old world with a new one." Said Sento, drawing lines between his Earth and Remnant.

"I'm surprised, I'd expect more people to show up. Considering it's just you two…" I said.

"Well… I'm not too sure THIS is the world we merged together." Said Sento, erasing the lines between the two worlds. "The world we saw was the exact same as our own, so the only thing I can assume is that when the worlds merged, Banjou and I ended up on Remnant due to us being entities that wouldn't exist in the other world."

"So how'd you guys end up here?" I asked, leaning back. "It might have had something to do with that portal thing you guys were taking Evol down in."

"That's a good enough guess as any." Said Sento, nodding. "So now that we explained how we got here, how'd you get here?"

I stood up, walking towards the whiteboard as I drew a Blank Ride Watch. "This was how. I'm not sure of the details but I think it had something to do with my personal watch."

"...Could I see one of thes-"

"No!" I snapped, taking a step back. I let out a sigh. "I just… Sorry, not right now."

"...Okay." Said Sento. "So, why exactly do you know us so well?"

"This'll be a long story." I said, taking out my phone and looking around, finding a speaker as I connected it up and hit play.

"In the city of Touto, home to the brilliant physicist Kiryuu Sento, mysterious monsters called Smash are attacking the citizens. It's then that our hero, Kamen Rider appears!"

"That's…!" Sento looked at me, as all attention was on me.

"Brilliant? Hero? You're just some dorky old dude with amnesia!" The voice of Banjou rung out.

"And me…?" Banjou asked in confusion.

"Shut it! This here is Banjou Ryuga, escaped convict and murderer."

"I ain't none of those things!"

"In my infinite kindness, I took pity on his crying and begging, and turned into a public enemy of Touto to help him escape-" I cut off the last few seconds of the Final Episode of Build, as the two turned to me.

"That… was the ending of Kamen Rider Build." I said, as Sento's eyes shot wide. "Kamen Rider Build… was a TV show, in my world. It's been one for many years now. Your show ended when you beat Evol, and fused with the mainline continuity."

"But we didn't." Said Sento.

"Right." I answered. "You wanted an answer as to why I know so much, I do because I was a fan of the show… I cried when you cried, and laughed when you did… You have my condolences."

I looked to the right, letting out a sigh. "Everything turned out well in the end, but at a great cost…"

"...Well, you two better get back to your dorms." Said Sento, motioning to two of us away. "I need to prepare for my class tomorrow."

"Why the hell am I your assistant again?" Asked Banjou.

"It wasn't my choice." Said Sento, as I smiled, walking up the stairway and out of the Refrigerator with Ruby.

"So… It's a show in your world?" Asked Ruby.

"Yeah. Well, Kamen Rider is, I don't know about this place, never seen this in a show before so…" I said, shrugging.

"But that means you know the riders more than me! I can't accept it!" Shouted Ruby, pouting at me.

"...I do have an entire season of Kamen Rider on my phone." I said, and in a literal split second, Ruby's eyes seemed to freaking sparkle, as she looked at me in expectancy. "...Okay fine, but only on weekend binging."

"Yes!" Ruby shouted, jumping in the air.

(LINE BREAK)

"Parado, I'm back." Said Emu, walking into the room. "How's the patient?"

"Hasn't woken up yet, but I've sensed something weird from him." Said Parado, as Emu walked over.

"You think it might be…?" Emu asked, to which Parado nodded. "I'll be one second."

Emu walked over to his desk, opening one of the drawers to show a green and pink driver of some kind. The doctor grabbed the driver, placing it against his waist as a belt formed around him.

Emu walked back over to the patient, putting on his stethoscope as a holographic screen popped up, warning signs popping up on the screen.

"Bugster." Said Emu, standing up. "Parado, take him to the CR room in the back."

"And where may you be going?" Asked Parado.

"I need to tell Ozpin about this." Said Emu, running off.

Parado smiled. "That's Emu for you…" He said, placing the patient onto a stretcher as he pushed the man into a back room.
