Beta read by someone.


"Ok, what the hell was that?! That surge of mana was ridiculous! Did the alien god appear already?! That's bad!" Shirou thought as he quickly stopped what he was doing and ran towards the direction of the surge he just felt. As he continued to head towards the source, he saw a large crowd in front of him, which included Ritsuka and Mashu. "Master? Mashu?"

"Shirou!"

"Master! Are you alright?! I felt a massive surge of mana and it came from here! Is everything ok?!"

"Well yeah…but you might want to look at this."

Upon seeing the scene, I was shocked to see my son holding two Muramasa blades, a portion of the hallway frozen, and a frozen statue that looked like he was trying to attack him. For a moment, I was confused about the statue but upon seeing it up close, I immediately knew who the attacker was. "Uh master…is that who I think it is?"

"Yes. That is Gilgamesh, and your son apparently froze him."

At that moment, I was completely baffled at my son's actions before coming up to him. "Oh, hey dad…" Kenzaki said.

I let out a sigh. "You used Hyouga Muramasa to freeze Gilgamesh?"

"To be fair, he deserved it, and it's not like I killed him." Kenzaki replied, which earned him a questioning look from me. "Relax! I planned on using Rekkajin Muramasa to thaw him out! And he's the one that started the fight by attacking me in the first place!" he reassured.

For a moment, I looked at the King of Heroes' frozen body before turning back to Kenzaki. "Then thaw him out. The director is not going to like this, especially with the damage you two caused…"

"The director? Who-"

And as if on cue, a pair of hands grabbed both of our arms. When I felt someone grabbing onto it, I turned around to see Olga Marie, who was wearing an annoyed look on her face.

"You two…in my office! NOW!"

(A trip to Olga Marie's office later…)

"So let me get this straight. Gilgamesh tried to attack you for a spiteful reason, and you froze him with this Hyouga Muramasa."

"Yes." Kenzaki replied.

Olga Marie let out a groan. "It's only been a day since your reveal to Chaldea, and Gilgamesh is already trying to kill you…like father, like son I suppose…" she muttered before turning to me.. "And you know what that Muramasa Blade is?"

"For the most part, yes."

"So…am I in trouble?" Kenzaki asked.

"Well…honestly, we all know this was going to happen eventually, but I did not expect it to happen this early…" she said with a groan.

"Um…why am I here, director?"

"Well, considering that you two mentioned two Muramasa Blades that even I haven't ever heard of, I assumed only you two know about them, correct?" she asked to which both me and Kenzaki nodded in reply. "Figures…well, what's done is done. Anyways, I want a full explanation about them, but right now we have another problem to deal with."

"Oh yeah…the King of Heroes."

"Yup. When we're done thawing him out of the ice, he's going to be so mad at both of you. I fear that he'll be uncooperative in the future due to this. So what are we going to do?"

For a moment, all of us were silent before Kenzaki decided to speak up.

"I have an idea, and it solves the problem and question you are currently having, director." Kenzaki said before he turned to me. "And dad…you and mom may not like it…"

At that moment, I was worried about what was the idea my son had in his mind…


The moment Gilgamesh was thawed out of his icy prison, his anger and fury reached new levels of heights unlike before. "WHERE IS THAT FAKER'S SPAWN?! I'LL MURDER HIM WITH MY OWN HANDS!" he yelled with a loud voice that could have broken some eardrums.

"Right here."

Gilgamesh turned around to see Kenzaki, who looked at him with a straight face, holding Sakegari Muramasa. As he did, he gritted his teeth in anger at the sight of Kenzaki, who froze him earlier. "There you are! How dare you freeze me! The King of Heroes!" he yelled as the Gate of Babylon activated behind him. Immediately, he shot swords at him, to which Kenzaki dodged them effortlessly.

"Whoa! Attacking me already?! He sure is pissed! And what I'm about to say next will definitely make him even more pissed!" he thought to himself. "Hey! What's wrong, Gilgamesh?! Is that the best you can do?!" he taunted.

That seemed to make Gilgamesh more angry than before. Immediately, he summoned more swords from the Gate of Babylon and threw them, planning on killing him. However, Kenzaki countered by summoning the six transparent Sakegari Muramasas around him, hovering like they were guarding him.

"Ha! Do you really think those will be enough!" Gilgamesh arrogantly said.

"It's not quantity that wins, but quality!" Kenzaki countered.

As if on cue, the six copies immediately left his sides and went towards the rain of swords. Upon contact, the copies began to deflect most of Gilgamesh's swords by making them bounce off of each other with each swing. The remaining swords that bypassed the copies' defense were then beaten easily by Kenzaki's swings. After the barrage was over, the copies disappeared as well and Kenzaki pointed Sakegari Muramasa at Gilgamesh. "Now then, it's my turn now!"

Immediately, Kenzaki lunged towards Gilgamesh with great speed and to his surprise, front flipped over him before quickly twirling around and swung at him, forcing Gilgamesh to block as he summoned a sword and blocked his swing.

Meanwhile, in a corner of the room they were in, Shirou watched the fight between his son and Gilgamesh. However, he was not alone as Ritsuka, Mashu, Gudako, Olga Marie, Da Vinci, and Romani were with him. "Kenzaki…"

"Um…Shirou-san, is this a good idea?" Mashu asked.

Shirou let out a sigh. "Honestly, I'm not fully supportive of the idea either, but he wanted to finish this with his own hands." he replied before turning to Da Vinci, Romani, and Gudako. "Although why are you three here?"

"Isn't it obvious? Ever since the director told me that your son froze the King of Heroes, I've been wanting to see what he can do! Seriously, a Muramasa Blade that can freeze people?! That's completely unheard of!" Romani exclaimed.

"Me too. Considering that this never happened in my timeline, I was wondering what he could do as well." Gudako replied.

"I'm here to record the fight." Da Vinci said as she was holding a camera.

"What for?"

"Considering who the people were in this fight, I expected a large crowd to arrive. So, to make things easier, I'm recording the entire thing." Da Vinci replied.

"I see…wait, recording?" he asked before the realization came into his head. "You mean that everyone in Chaldea will be watching this?"

"When it's done, yes."

Shirou mentally groaned. "Arturia may not like this…"

"Seriously though. The plan your son has…I don't know if he has a death wish or what, but it's the most reckless plan anyone could ever think of." Olga commented. "Then again, he is your son after all."

Back with the fight, Kenzaki and Gilgamesh were swinging their swords at each other. As Gilgamesh swung at him, Kenzaki dodged and turned around before kicking him in the stomach, clearing space between the two. "You bastard!" he yelled as he recovered and began to throw swords at him again.

In an unorthodox move however, Kenzaki went towards a wall and began to wall climb before kicking it off, unleashing an aerial attack as he swung downwards. However, Gilgamesh blocked it before summoning another rain of swords at Kenzaki.

In return, Kenzaki moved backwards while summoning the copy blades again for defense; each copy blade deflecting the rain of swords.

It was then Kenzaki let out a sigh as he relaxed himself, letting the other Muramasa Blade disappear. "You know…for someone that's known as the King of Heroes…you don't seem to feel like a king right now."

That stung a nerve for Gilgamesh. "Huh?! What is that supposed to mean?!"

"Isn't it obvious? Even since you first saw me, you've been acting like a creepy stalker in denial! I mean, seriously! Attacking me just because I'm the offspring of Emiya Shirou and Arturia Pendragon?! Really?! That's really low how a person can get! I swear, that creepy obsession with my mom is pretty much hindering you!"

That got Gilgamesh riled up. "Creepy obsession?! Hindering me?! Who do you think you are?!"

"Someone with common sense, idiot!"

"Wow. This escalated quickly…better hope he does not meet Medea…" Shirou and the others thought in unison.

"Seriously, if you continue to act like a creepy stalker towards my mom, she'll end up hating you for all eternity! Maybe you should learn from my dad!" Kenzaki yelled.

"Huh?! Like why should I learn anything from that faker?! It's ridiculous!"

"He's never going to learn at this rate…" Kenzaki thought. "Then…let me show you something that should give you a wake-up call."

Kenzaki then stabbed Sakegari Muramasa onto the ground and said one word. "Realize." he chanted.

Immediately, a giant red circle appeared around himself, Gilgamesh, Shirou, and the others in the room. Upon seeing the circle, Shirou and the others knew what was going on. "This is-!" Shirou thought.

"Now…let me show you…my world."

Then, everything was engulfed in a bright light…


Shirou and the others covered their eyes over how bright the light was. After the light died out, they opened their eyes to see something that shocked them, especially Shirou.

Kenzaki's reality marble, and it looked almost identical to Shirou's as it came with the Emiya Residence and a bunch of weapons, but with one crucial difference.

There were five islands in the sky, large enough to be continents. And each island was different.

One island had a tree-like tower in the center, surrounded by what appears to be stone giants. One island looked like a split between modern Japan and a European city, separated from each other. One island looked like Modern Seoul. One island looked like a futuristic city. And the last island looked like a split between Modern Tokyo and a digitized city where they were separated from each other.

For a moment, Shirou and the others were completely stunned with the scenery in front of them, and even Gilgamesh stopped his rage for a moment just to look at it. "What the hell is this…"

"What all of you are looking at here…is the result of my journey." he said as he looked up at the sky while picking up Sakegari Muramasa. "Each island represents the worlds that I've visited, and each world showed me something I would have never expected to see." he said as he picked up a nearby green Muramasa Blade. "And…I received power…from each world."

"So this…this is Kenzaki-san's reality marble…" Mashu said in amazement.

"Like father, like son I would say…" Olga Marie muttered with Da Vinci and Romani nodding in agreement.

"What the heck? Floating islands...that's a new thing to look at." Gudako said.

"Tell me about it." Ritsuka replied in agreement.

"What's the point of bringing all of us here? If the point is for a show and tell, then you're wasting your time." Gilgamesh said arrogantly.

"That…is for you to find out for yourself! Blow through, Kazenami Muramasa!"

Immediately, Kenzaki swung the green Muramasa blade at Gilgamesh. When he did that, a human-sized tornado suddenly appeared and headed towards Gilgamesh, forcing him to dodge. "What?!" he yelled.

However, Kenzaki was not done as Sakegari Muramasa was suddenly replaced with a familiar orange Muramasa Blade. "Dance to ashes, Rekkajin Muramasa!"

Immediately, Kenzaki began to dual wield both Kazenami and Rekkajin Muramasa and swung at Gilgamesh gracefully, as if he was dancing. There was no waste of movement within each swing and step, and the two Muramasa Blades resonated with each other due to their elemental properties. For a moment, Gilgamesh could not help but admire his movements.

And he cursed himself because of it. To him, that meant he was superior to him, and he hated that.

Back with Shirou and the others, almost everyone was surprised with the Muramasa Blades Kenzaki was bringing out, with the exception of Shirou because he knew beforehand. "So, he's bringing out the rest of the Next-Generation Muramasa Blades huh?"

"Eh? Next-Generation Muramasa Blades?" Ritsuka asked.

"Yeah. The Next-Generation Muramasa Blades are Muramasa Blades forged with materials from the other worlds he visited. For example, Rekkajin Muramasa was forged with parts of a fire monster from one of the worlds he visited."

"I see…" Ritsuka said before noticing that Gudako was staring at one of the islands. "Gudako? Is there something wrong?"

"Well no. It's just…that island over there…it looks familiar, but I can't remember why though…" Gudako replied.

"Which one?" he asked before Gudako pointed to the island with the split cities. "That one?"

"Yeah. For some odd reason, my gut has this weird feeling upon seeing it. I don't know why though…"

"Say…are you sure he only knows Projection and Reinforcement? Because if you were to tell me, I would think he has an affinity with every element!" Romani said.

"Tell me about it! A Muramasa Blade that shoots tornados?! That's ridiculous, even by magecraft standards!" Olga Marie yelled.

"Next-Generation Muramasa Blades…sounds interesting…" Da Vinci said with interest. "Are those the only weapons he forged?"

"Well…he said he forged other weapons…but didn't give me any details about it. And he did mention…there was one certain gift he received that he even couldn't believe."

"What is that supposed to mean?" Mashu asked.

"I don't know."

Back with the fight, Kenzaki was unleashing relentless attacks against Gilgamesh, and they were working. Each sword swing that Gilgamesh was defending against felt like either a inferno or a typhoon. Having had enough of it, Gilgamesh moved back and unleashed the Gate of Babylon on him again.

Upon seeing the familiar rain of weapons coming at him, Kenzaki brought the two swords together into a x and slashed, creating a flaming x that countered the rain for swords. As the two clashed, it created an explosion large enough to cover both sides. As the smoke cleared, Kenzaki was holding a certain Muramasa Blade.

"Set everything to absolute zero, Hyouga Muramasa!"

Immediately, Kenzaki used the familiar ice-blue Muramasa Blade and unlike before, he just stabbed it onto the ground. However, what happened next was that the ground around him started to turn into ice and it was spreading wide at a fast rate. Not only that, but the air around him was getting cold, enough for Shirou and the others to feel it from a distance.

"So that's how Gilgamesh was frozen…" they thought in unison.

Seeing the ice coming towards his legs, Gilgamesh jumped before seeing that Kenzaki disappeared from his spot…and was sprinting on the ice before jumping towards Gilgamesh with a purple Muramasa Blade in hand. "Bring forth the thunder! Raimei Muramasa!"

In a quick flash, Kenzaki slashed Gilgamesh with Raimei Muramasa, dealing damage to him. The damage itself was effective as not only he cut through his armor, but Gilgamesh got shocked within seconds later, feeling an electric shock going through his body. Kenzaki landed on the ground first while Gilgamesh was dropped to the ground like a rag doll.

"Impossible! The faker's spawn is only using those blades, and I'm already pushed to this condition! How dare he make me fall so unsightly like this!" Gilgamesh thought angrily as he was getting up.

"You know, you're really predictable." Kenzaki said as he saw Gilgamesh get up.

That got Gilgamesh really angry. "Predictable?! Me?!" he yelled.

"Yeah. All you've been doing is just using the Gate of Babylon just to either throw swords at me or grab one to defend yourself. I mean, don't you have anything else to use?! Like a shield for example?! Or any other tactics to use?! If anything, I think outside of the Gate of Babylon, you pretty much can't do anything in a fight! I mean, no offense, but you're boring me! Learning something new once in a while!"

"Boring you?! Me?! How dare you say that to me, the King of Heroes! Just what gives you the right to say that to me?!"

Kenzaki was silent before letting out a deep sigh. "Throughout the worlds I've visited, I've seen, fought with and against many people, and learned what drives them to do what they do. From my time in those worlds, I've seen their motivations make them stronger and surpass their limits to do things I would have never imagined to see. But seeing you…I don't feel any motivation in any of your attacks." he said as he stabbed Raimei Muramasa to the ground.

The air was silent before Kenzaki said his next sentence.

"All I can feel from your attacks…is the arrogance of a spoiled man-child stuck in his own delusions and past! And it's making you weak!"

That got Gilgamesh pissed off and shocked everyone else. "WHAT?! WEAK?! ME?!" he yelled.

"Yeah! You heard me! That arrogance of yours is making you weak! Compared to the people I met and fought in the other worlds, your attacks are empty compared to theirs! In fact, the last person I fought alongside was far stronger than you!"

That got everyone shocked at Kenzaki's statement. "Someone far stronger than Gilgamesh other than me/Shirou/Shirou-san/Emiya Shirou?! And that person was from one of those worlds? Wait…does that mean that person is stronger than Asakim Dowen as well?!"

"And speaking of which, why do you keep calling my dad a faker?!"

"His false existence is a constant eyesore in my eyes! That magecraft of his is a mockery of my treasures! In my personal opinion, that mongrel should have died painfully and pathetically in the holy grail war and let me claim what is rightfully mine!"

At that moment, Kenzaki snapped and suddenly, mana was suddenly leaking from him, making Shirou and the others worried. "Right now…what did you just say? Did you say that my dad should have died in the holy grail wars just for you to claim what is yours? And a false existence?" he asked coldly.

"Yes! Is there a problem with that?"

For a moment, he did not say anything until he let out a deep sigh. "You know…there are some things I can tolerate…but what you just said…is not one of them."

At that moment, Kenzaki's eyes turned into the Lion King's. For a moment, Ritsuka, Mashu, Gudako, and Da Vinci gulped at those familiar eyes.

"I was hoping you would find the lesson from our previous clashes, but right now, none of that matters...because I'm going to pulverize you." he said with a growl at the end.

Then two items suddenly appeared in Kenzaki's hands, but they were not weapons. The item in his left hand looked like a black belt buckle while the item in his right hand was red and looked like an add-on. While Gilgamesh was confused with what they were, the others knew it looked familiar.

"Is that…a belt buckle?"

However, when Kenzaki put one of the items on his waist, their assumptions were confirmed to be real as two words were suddenly heard from the belt buckle itself.

Desire Driver.

"Eh?" Shirou and the others thought.

Then Kenzaki split the other item.

Geats Alter!

And placed the two halves onto the Desire Driver. "Sorry, Ace."

Set Crossover.

Suddenly, music started to play in repeat before Kenzaki started to pose as his left arm was in front of him at an 45 degree angle while his right arm was on his waist.

And then he snapped his fingers on the left hand.

"Henshin." he said before he tapped onto the driver and rotated the driver.

Revolve on.

Then the belt began to have the image of a nine-tailed fox before he tapped on a lever. Immediately, a red and yellow fox and an image of a logo appeared behind him before the fox began to run around him.

Alternative boost! Geats Alter!

Then the fox and image turned into armor while Kenzaki was transformed into wearing what appears to be a faceless bodysuit before the armor latched onto him, turning him into what appears to be a futuristic fox-themed knight, armed with a red and yellow gun-blade.

Ready, fight!

At that moment, everyone was stunned with what Kenzaki had turned into. Even Gilgamesh's rage subsided for a moment.

"What is…that form?!" Gilgamesh yelled.

Kenzaki let out a small sigh before answering his question. "Kamen Rider…Geats Alter."


Author's Notes: Yup, I crossed that line again. Also, if anyone wants to know what Geats Alter looks like, it's basically a repainted Dooms Geats with Geats IX's leg armor and arm gauntlets. The repainted colors are red and yellow, and the eyes on the helmet are green. For the color separation, the colors are separated like XGeats where nearly the entire body is red with yellow pinstripes. Also, the music that happens before the 'revolve on' is the first five seconds of Kizuna no Kiseki on repeat. Then the music after that is the music segment that happens between 0:11 and 0:22 of Kizuna no Kiseki. The driver's sounds are the same as Dooms Geats's. Anyways, I do not own the Kamen Rider properties. Toei does. And I do not own Kizuna no Kiseki. MAN WITH A MISSION×milet does.
