After the Thundergods crashed the party following the fight against Yuuki's older sister and her friends, things went from bad to absolutely catastrophic.
They had thought the half-Shuuki were with allies these two, but they couldn't have been more wrong.
With Tenka, Aoba, and all the members injured and immobilized after the attack the antlered Thundergod carried out, the situation was hopeless. To make matters worse, the two half-Shuuki were now in their hands.
Kyouka could only hope for the best, even though she had already slain the unihorn that once destroyed her hometown.
"Yuuki!! Brace yourself!" Kyouka shouted as she remained on top of his slave form.
"You got it!" he answered with vigor.
The black-haired Thundergod smiled innocently, standing amid the chaos she herself had created.
"Too bad~~ but time to say bye—"
"Hold your phone, evildoers!!!"
Shikoku was about to hurl an insult, but a male shout cut him off.
Curious, Kyouka turned her head to see who had interrupted them.
"Born from the lovely prefecture of Yamanashi, I, the protector of Mato, have come to stop this madness!" a guy shouted with pure vigor.
Everyone, even the Thundergods, stared in confusion at the top as a black-haired guy posed like a retard.
"Who is this idiot?" the black haired Thundergod said. "One of you?"
"We don't know anyone like that." Despite being hostile to her, Kyouka answered.
Even Kyouka is confused about how this guy ended up here.
A Mato mishap, perhaps?
If so, having a civilian present here was going to be nothing but trouble.
Before Kyouka could call out his presence, the guy pulled out two bottles, red and blue. He started shaking them while ignoring the stupefied faces of everyone.
[ℝ𝕒𝕓𝕓𝕚𝕥]
[𝕋𝕒𝕟𝕜]
[𝔹𝕖𝕤𝕥 𝕄𝕒𝕥𝕔𝕙!!!]
A smirk crept across his face as he spinned the handle on the belt where the bottles were slotted. A voice burst from the device equipped on his waist.
Interlocking pipes surged outward, snapping together as if guided by unseen hands, forming layered armor across his front and back, glowing in vivid red and blue.
[𝔸𝕣𝕖 𝕪𝕠𝕦 𝕣𝕖𝕒𝕕𝕪?]
"Behold," he proclaimed, his voice brimming with confidence, "the power of god and anime!"
Striking a confident pose, he shouted—
"Let's! Henshin!"
The liquid-filled pipes spiraled around his body, merging in a violent rush. Smoke billowed outward, and when it cleared, he stood clad in a sleek red and blue suit, transformed.
[ℍ𝔸𝔾𝔸ℕ𝔼 ℕ𝕆 𝕄𝕆𝕆ℕ𝕊𝔸𝕌𝕃𝕋!!!!]
[ℝ𝔸𝔹𝔹𝕀𝕋!!! 𝕋𝔸ℕ𝕂!!! 𝕐𝔼𝔸ℍℍℍℍ!!!!!]
"Now then… shall we begin the experiment?" The man in the suit said calmly, his gloved fingers slowly brushing over the tip of his helmet.
The injured members of the 7th and 6th squads at the scene were filled with confusion, their heads spinning at the man's sudden transformation, growing more bewildered with each passing second.
"Isn't that a Kamen Rider?!!" Yuuki said in a flabbergasted tone. He had already seen more than enough strange things in Mato, but a tokusatsu showing up was nowhere on his mental checklist.
"I have many names but you can just call me" He said as he striked a pose, pointing at the sky while touching his hips "Emiya Shirou! The Hero of Justice!"
On the opposite end of the spectrum, the black-haired woman and the tall woman with antlers reacted very differently from the Mato members.
"Neh, Shikoku," the antlered woman called to her partner. "Is it just me, or does that guy feel way too familiar?"
"What a coincidence, Jouryuu. I was thinking the exact same thing," the black-haired woman named Shikkoku replied.
The man in the suit glanced between Jouryuu and Shikoku, then snapped his fingers as recognition clicked into place.
"Wait a second… it's Snake-chan and Muscle Mommy!" he shouted cheerfully. "Wow, long time no see! How've you been?!"
The moment those words left his mouth, a suffocating killing intent poured from both of them.
"…It really is that man," Shikoku muttered, her voice tight with rage. "You'd better start preparing for your demise."
His current state might have looked different from the purple dinosaur they fought last time, but there was no doubt about it.
The annoying voice. The annoying personality. The habit of giving annoying nicknames.
We're going to rip you to shreds Shikoku and Jouryuu thought at the same time.
"Now, now, ladies. I know I'm irresistible, but you've gotta chill," he said in a shy tone.
Before he could utter another word though, multiple black snakes appeared behind him.
He just laughed and leapt aside, narrowly dodging their attack.
"Eat this!" he shouted.
"RIDER KICK!"
He launched himself into a flying side kick, descending straight toward them. Jouryuu swiftly jumped in front of Shikoku to take the blow.
The ground beneath them shook from the impact.
The Kamen Rider leapt back, boots scraping against the ground, then launched himself forward again to attack her.
Jouryuu brought her arms together and raised them into a high block. She absorbed the punch, then immediately grabbed him and slammed him into the ground.
"Damn, I really like your rough treatment, baby," the Kamen Rider laughed while lying flat on his back. He rolled aside just in time, dodging Jouryuu's downward punch as it shattered the earth where his head had been moments earlier.
He sprang back to his feet, quickly assessing his next move before making a decision.
[BELT CHANGE: RANDOMIZER]
[KAMEN RIDER: OOO]
"Now that's more like it," he smirked beneath his mask.
His belt began to glow, forming an item with three empty circular slots. As he defended himself from Jouryuu's relentless barrage of punches, three medals emerged from his chest and snapped into place within the belt.
Dashing backward, he grabbed the circular handheld device at his side and scanned the medals.
Multiple colored rings erupted around his body, deflecting Jouryuu's incoming kick and sending her flying a short distance away.
[𝕊𝕒𝕚]
[𝔾𝕠𝕣𝕚𝕝𝕝𝕒]
[ℤ𝕠𝕦]
[𝕊𝕒-𝔾𝕠-ℤ𝕠... 𝕊𝕒-𝔾𝕠-ℤ𝕠!]
Instead of blue and red, his armor shifted into a fully gray suit, featuring a massive arm and a horned helmet.
Kyouka felt her body suddenly grow heavier as he began pounding his chest repeatedly like a gorilla, letting out a powerful roar.
Ignoring the sudden shift in gravity, Jouryuu just stared at him. Assessing the situation, she decided it was best to retreat for now.
"I know you want to kill that guy, but the life force takes priority," Jouryuu said in a relatively calm manner. "We don't know when he'll use that purple suit again."
"Tsk." Shikoku clicked her tongue in irritation. "Fine."
Grabbing a shuuki deck, Shikkoku threw it towards Kyouka before being grabbed by Jouryuu.
Multiple hostile shuuki came out of the cards. Despite being weak, their numbers are no joke.
After losing their sight on the Thundergod, they vanished without a trace.
"Damn, they just pulled a Batman, but I'll catch them next time!" the Kamen Rider clicked his tongue, snatching a Shuuki launching at him. He hurled it toward the other Shuuki about to strike the immobilized group.
The cave was collapsing in on itself, so escaping became the priority.
"Gather the injured! I'll teleport us out of here!" Tenka shouted, coughing as she pushed herself upright, urgency lacing her voice.
Without a word, Yuuki, Kyouka, and the Kamen Rider rounded up everyone. Tenka then activated her ability, teleporting herself and the rest to safety.

"Mission accomplished—my ass! I let them get away again," the Kamen Rider shouted, scratching his head.
With the enemy gone, Kyouka finally decided to address him.
"So… answer me truthfully. Who are you?" she asked, cautious but calm despite his assistance.
The man looked around before pointing at himself.
"Me?" he replied.
"Obviously. Who else?" she said.
He coughed and straightened himself.
"I already told you. My name is Emiya Shirou!"
Yuuki stepped in, a wry smile tugging at his lips even in his slave form.
"Uh… sorry, but isn't that a game character's name?"
The Kamen Rider groaned and tapped his head in exasperation.
"I'm just a passing through Kamen Rider. That's what you need to remember!" he said, giving a thumbs-up.
Kyouka stared at him dryly before remembering something.
"Oh, right. I've been receiving reports about a masked guy causing trouble at the Ogre Gate… was that you, perhaps?" she asked.
The masked man shook his head.
"I don't know about that, but that guy might know," he said, pointing over her shoulder.
Yuuki and Kyouka glanced where he was pointing.
But no one was there.
"What do you mean, no one—geh! He's gone!" Yuuki exclaimed, spinning around in surprise.
Kyouka felt her nerves fray but let out a long sigh, reminding herself to be grateful that Yuuki was safe and that the rest of their group had made it out.
"No matter. I have a feeling we'll run into that guy again," she said, walking toward the location where Aoba, Yuuki's sister, was.
"I'll probably ask Mira for more details about that masked individual she saw wreaking havoc," she murmured. "Anyway, good job today, Yuuki."
She smiled and lightly tapped the back of her slave.
"I'm just glad Himari and the others are safe," Yuuki replied.
Yuuki and Kyouka continued talking as they walked, until Aoba finally came into view.

Think of this chapter as a messy pilot chap. It's mostly crackfic, but the next chapter(If I get interested in writing) is where the actual plot(might) begin.
