Author's note: While I was writing this, apparently Delight Works had the balls to release Proto Merlin...on FGO Arcade only. WTF. Let's just hope the same doesn't happen on other characters...
Anyways, hope all of you like this...
Also, Proto-Merlin chapter in the future...
"So, let me get this straight. You want to see Sengo Muramasa?" Shirou asked.
"Yes. That's exactly right Shirou," Merlin said.
"But why? Why do you suddenly want to meet Muramasa, Merlin?"
"Well, the story between you and him interests me. While I have heard of the concept of a heroic spirit possessing a mortal body, it usually ends up with the heroic spirit taking possession of the body. However, in your case, you managed to retain your mind while gaining Sengo Muramasa's skills. Not only that, but you are able to communicate with Sengo Muramasa as well in your reality marble while he also shares your body by residing in your reality marble."
"I see. But why are you asking me? Why not ask Mashu since she's the same as me?"
"Well normally I would, but...she's out with master now."
Shirou let out a small sigh. "Figures..."
"Anyways, would you help me grant this flower mage's request, Queen Shirou?" Merlin asked with a smirk.
Shirou sighed again. "Just give me a moment to see if Muramasa is okay with that idea of yours," Shirou said.
Merlin let out a smile. "Great! Now go and ask him!"
"Will do. Just let me activate my reality marble for a moment..." Shirou said as he closed his eyes and began to activate his reality marble.
"Ah wait. Not like that," Merlin interrupted him.
Shirou was confused. "What do you mean by that?"
"Well...I want him to possess your body for a moment."
Shirou was surprised for a moment before saying, "Huh?!"
Muramasa was relaxing in the copy of the Emiya Residence, looking at the clear blue sky of the reality marble. "Wow, what a great view my host's reality marble has. A clear sky, a lush green field of various flowers, and most importantly...there are swords everywhere for me to study. Speaking of which, I wonder what is that giant contraption my host traced a while ago?" he thought as he then turned to the Strike Freedom Gundam in the corner nearby the Emiya Residence. "Even now that giant contraption still confuses me. I've never seen this type of thing before in my lifetime."
As Muramasa continued looking at the Strike Freedom Gundam, he felt a familiar presence coming in. He then turned around to see Emiya Shirou. "Hey there Shirou."
"Hey there Muramasa," Shirou said as he sat down on the porch.
"So. What brings you here? You got into trouble again and need my advice?" Muramasa jokingly asked.
"Nope. Rather, it's a request from Merlin."
"Merlin? Who's that? Is that somebody new?"
"You already seen him before. White hair, white robes, carries a wooden staff? Remember?"
"Oh yeah. I remember seeing a fellow that matches your explanation. It was during that time when you brought a lot of people here for your noble phantasm testing."
"Yeah...along with that was when I beat the King of Heroes."
Muramasa let out a chuckle upon hearing Shirou saying that. "Hah! That arrogant golden brat had it coming! I take it that word has spread about that event?"
"You have no idea. After that event was spread throughout of Chaldea, nearly everyone at Chaldea wanted to meet me because of either wanting to have a sparring match against me or wanting to look at Tsumugari Muramasa. Not only that, but I have been receiving requests to join parties from other servants, especially the Japanese servants. They consider me as their inspiration because of how I beat the King of Heroes with your noble phantasm."
"Well then, guess you're getting popular after all!" Muramasa said while laughing and slapping Shirou on the back.
"Yeah...and it was something I did not expect..." Shirou said as he was breathing in some air from Muramasa's slaps on the back.
"Anyways, what was the request that Merlin fellow wanted to talk about?"
"Well...he wanted to speak to you."
Muramasa was surprised. "Me? He wanted to speak to me?"
"Yeah."
"What for?"
"He's interested in the story of how you and I met."
"Is that so? Then why not activate your reality marble and invite him in like before?"
Shirou let out a sigh. "Apparently, he wants to speak in front of you without any hesitations or interferences. Meaning, he wants you to possess my body for today."
Muramasa was stunned. "Are you serious?"
"Yeah."
"I see."
"So...do you accept Merlin's request?"
Muramasa gave Shirou's question a long thought. "Hm...one whole day of possessing my host's body...it does sound interesting. And I do want to see what Chaldea is like, along with some of the other servants that live over there..."
For a moment, there was silence between the two as Muramasa was still in thought.
"Well?" Shirou asked.
"All right. It wouldn't hurt to possess your body for today. And plus, I do want to see what Chaldea looks like."
Shirou smiled. "All right. Should we commence the possession then?"
"Sure. But before that, there's something I want to ask."
Muramasa then turned to the Strike Freedom Gundam.
"What the heck is that?" he asked as he pointed to it.
Shirou let out a sigh. "Let me explain..."
Merlin was waiting for Muramasa to appear. "Wonder what's taking Shirou so long? A possession shouldn't take that long. Maybe they're having a chat about something?" he thought as he was looking at Shirou who had his eyes closed.
Soon, Shirou opened his eyes.
"Um, is this Shirou or Sengo Muramasa that I am talking to?" Merlin asked.
For a moment, there was silence between the two. Then a voice came out of Shirou's body.
"Huh? Who are you? Are you Merlin that Shirou was talking about by any chance?" Muramasa said.
Merlin let out a smile now knowing that the person he was talking to is Sengo Muramasa. "Yes. I am Merlin, the Wizard of Flowers. It is a pleasure to meet you Sengo Muramasa."
"Wizard of Flowers? Isn't that a flashy title for you?" Muramasa said with a chuckle.
"Well that's rich, coming from someone who was called the Demonic Blacksmith," Merlin replied.
Muramasa let out a sigh. "You got me there. Anyways, you said that you wanted to know the story about how I met my host."
"Precisely. However, would you mind if we take this conversation somewhere else? I prefer the cafeteria since there's food and drinks over there."
"I don't mind."
"Great."
Muramasa and Merlin then walked towards the cafeteria. As they were walking, they came across a certain group of servants.
The Knights of the Round.
"Queen Shirou!"
"Mother!"
Muramasa was surprised with the names the Knights of the Round just said. "Queen Shirou? Mother? Just what kind of trouble did my host managed to get himself into? Never mind, Shirou is a literal magnet of trouble. I mean, I've seen him in many situations that want him dead."
Soon the Knights of the Round went up to where Muramasa and Merlin were.
"Hey mother, what's for dinner tonight?" Mordred asked.
Muramasa was confused. "Mother? Who's the mother?"
"What? Have you forgotten already? It's you."
Muramasa then looked to Merlin. "Merlin, what is going on here?" he whispered to him.
"Well, you see, a while ago, because of Shirou's relationship with Arturia and her counterparts, Mordred sees you as her new mother," Merlin whispered back to him.
"I see."
"Hey, what are you two talking about?" Mordred interrupted.
Muramasa then turned to Mordred. "Listen kid, I'm not Shirou not now."
"Eh? Then who are you then?"
"Sengo Muramasa."
The Knights of the Round were surprised upon hearing Muramasa's introduction. "Eh? You're Sengo Muramasa? Our queen's ancestor?" Gawain asked.
"Yeah."
The rest of the Knights of the Round then turned to Merlin. "Merlin, what have you done to our queen?!" Lancelot asked.
"Hey! Hey! I didn't do anything!" Merlin defended.
"Oh really? Because it looks like it has your work written all over it," Tristan said.
"So, tell me, what did you do to Queen Shirou?" Bedivere asked.
"Yeah!" Gareth said.
As Merlin was being interrogated by the Knights of the Round, it was then that Muramasa decided to step in. "Hey, lay off the wizard for a moment. While this was his idea, he didn't do anything to me, so lay him off, got it?"
Hearing Muramasa's words, the Knights of the Round stooped interrogating Merlin and listened to what Muramasa has to say.
"All right. There's a reason why Shirou is not here and why I am here. The thing is that Merlin wanted a request to talk with me, so Shirou and I swapped places. Right now, Shirou's is inside this body's reality marble."
"I see..." Gawain said.
"Yeah. So lay off the wizard or else I'll bash all your heads in! You got that?!" Muramasa yelled.
"Y-Yes!"
Muramasa let out a sigh. "Well then, I suppose we should move on Merlin?"
"Yeah..." Merlin replied with a sigh as well.
"Wait. There's something I need to ask you Muramasa," Mordred said to Muramasa.
"Hm? And who are you?"
"I'm Mordred."
"Mordred huh? Were you the one that kept calling me mother?"
"Yeah. You got a problem with that?"
"Nah. That's Shirou's problem to deal with, so it's not my problem."
"I see. Well then, I have one question to ask you then."
"Sure. What is it?"
"Well, since you're my mother's ancestor, should I call you great, great, great, great, great, great grandmother or great, great, great, great, great, great, step grandmother? Or great, great, great, great, great, great grandfather or great, great, great, great, great, great, step grandfather?"
For a moment, there was silence as Mordred was waiting for his answer.
"Just call me what you want. I don't care."
Mordred smiled. "Is that so? Then I should call you... great, great, great, great, great, great grandfather then."
"Whatever you wish. By the way Mordred."
"Huh?"
Muramasa then took off the white kimono and put it on Mordred. "Wear this. I don't want you to catch a cold while you're wearing that," Shirou said as he pointed to her outfit.
Mordred quickly blushed. "F-Fine. Whatever you say great, great, great, great, great, great grandfather. Come on you guys." She then proceeded to leave Muramasa and Merlin, with everyone else following her.
"Well then. See you Muramasa. Merlin," Lancelot said.
"Yeah. Bye you guys."
"Bye," Tristain, Bedivere, and Gareth said as they left.
"Well then, shall we move on?"
"I agree. Let us move on then."
Muramasa and Merlin then resumed their walk to the cafeteria. As they did, they came across a certain servant that knew Muramasa.
"Shirou-kun!"
Both Muramasa and Merlin turned around to see where the voice was coming from. It was from Musashi, who was walking towards them from behind.
"Ah Musashi. It's been a while since I last saw you," Muramasa said.
Musashi was confused with what Muramasa said. "What do you mean Shirou-kun? The last time we saw each other was during our practice match against each other a few days ago! Is there something wrong with your head?"
"Huh? Oh yeah, this may sound weird to you, but you're not taking to Shirou right now. It's me, Sengo Muramasa, Musashi."
Musashi was surprised. "What?! Gramps?! You're here now?!"
"Yeah."
"But how?!"
"Well, let's just say my host let me possess his body for one day under the request from this man right here," Muramasa said as he pointed to Merlin.
"Is that so?" Musashi then turned to Merlin. "And who are you?"
Merlin's lips turned into a smile. "Ah, I see we haven't met before my fair lady. My name is Merlin, the Wizard of Flowers," he said with a bow in the hand.
"I see. Nice to meet you Merlin!" Musashi said cheerfully with a bow as well. "Anyways gramps, what kind of request did Merlin ask you for?"
"Well, he was interested in the story about my meeting with my host, so he asked me to do this."
"I see. But why in this way though? Couldn't he just do the same way as before?"
"Well apparently, this guy here wants to do it without any inferences," Muramasa said as he pointed at Merlin who kept on smiling. "Anyways, we're on our way to the cafeteria. Want to join us?"
"I can't. I got to do something for master later, but thanks for asking!" Musashi exclaimed happily.
"I see. I guess that we'll be leaving now then," Muramasa said.
"Okay. Bye gramps!" Musashi said excitedly as she left.
"Great. Now, let's move on, shall we?" Merlin asked while one of his eyes was twitching from the amount of attention Muramasa was receiving from Musashi.
"Yeah," Muramasa replied, not knowing what Merlin was feeling now.
Muramasa and Merlin then continued walking down the hallway. As they did, they ended up meeting another group of servants.
Okita and Okita Alter.
"Shirou-san!" the two said in unison.
Muramasa let out a sigh. "Not this again..." he thought as Okita and her alter went up towards him. "Who are you two?"
"Eh? You don't remember us Shirou?" Okita asked.
"Yeah. About that, Shirou's not here now," Muramasa said.
"Then who are you then?" Okita Alter asked.
"Sengo Muramasa."
"Eh?! The Demonic Blacksmith?! You're here Sengo-san?!" Okita asked.
"Yeah. If you're wondering why I'm here now, it's because Shirou and I swapped places because of him right here," Muramasa said as he pointed to Merlin, who let out a small smile.
"I see...anyways, can I ask you something?" Okita Alter asked.
"Sure. What is it?"
"Can you make a Muramasa blade for me?"
Okita was surprised by his counterpart's question. "My altered self! Why are you asking Sengo-san such a request?!"
"Eh? But I want a Muramasa Blade..." Okita Alter muttered.
Fearful of the fact that her altered counterpart just made a selfish request to a well-known blacksmith, Okita quickly grabbed her altered counterpart by the shoulder and started bowing apologetically to Muramasa. "I'm sorry Sengo-san for my altered counterpart's rude request! If you will excuse me, I'm going to teach her some lessons now!"
Okita then dragged her altered counterpart away, confusing Muramasa.
"Just what was all that about?"
Muramasa then continued his walk with Merlin. As they did, they somehow ended up meeting with Jeanne D'Arc and her counterparts.
"Shirou/Shirou-san!" Jeanne D'Arc and her alter santa lily counterpart yelled while Jeanne D'Arc Alter was following them.
Muramasa let out a sigh. "Really? A third time?" he thought as Jeanne D'Arc and her counterparts were coming up to Muramasa. "Listen, before you can say anything yet, Shirou is not here now.
"Eh? Then who are you then?" Jeanne D'Arc Alter Santa Lily asked.
"Sengo Muramasa."
"I see. Hey adult me, don't you have anything to say to him?"
Jeanne D'Arc Alter then blushed. "W-What?! What are you talking about?!"
"You know. Just say it to him," Jeanne D'Arc said with a smile that even terrified Jeanne D'Arc Alter.
Realizing that there was no way out of this, Jeanne D'Arc Alter then said something to Muramasa.
"Tch. Hey Muramasa, next time you see Shirou, tell him that Jeanne D'Arc Alter appreciates the extra tutoring from before..." she muttered to Muramasa.
"I see...well, I'll tell that to him when I see him next time," Muramasa said.
"Good." Jeanne D'Arc Alter then went back to her counterparts. "There, I said it. Happy now?"
Jeanne D'Arc let out a smile. "Yes. Anyways, we'll be leaving now. Bye Sengo Muramasa!"
"Bye Sengo Muramasa-san!" Jeanne D'Arc Alter Santa Lily said.
"Tch...bye Sengo Muramasa," Jeanne D'Arc Alter said.
And Jeanne D'Arc and her counterparts left, leaving Muramasa and Merlin alone. "Who was that?" Muramasa thought.
However, before he could complete his thoughts, another certain group of servants came by.
"My Praetor!"
Muramasa was shocked at the amount of girls he was recognized just now. "Okay, how is it that Shirou knows all of those girls...?"
"My praetor! How happy am I to see you!" Nero said in a joyful tone.
"Umu! It's been quite a while!" Caster Nero said.
"Umu! What are you up to my praetor?" Bride Nero asked.
Muramasa sighed again. "Okay, this may sound weird to all of you, but I'm not Shirou at the moment."
"Eh? Then who are you then?" Nero asked.
"Sengo Muramasa."
"Eh? Sengo Muramasa? Our praetor's ancestor?" Caster Nero asked.
"Yeah."
"Well this is interesting! How did this happen?" Bride Nero asked.
"Well, me and Shirou switched places for today, and that's it," Muramasa replied.
"I see...umu! There is a lot of things I want to ask you Muramasa!" Nero said.
"As so do I!" Caster Nero said.
"Me too!" Bride Nero said.
As Muramasa was being bombarded with multiple questions from Nero and her counterparts, Merlin was feeling jealous from the sidelines. Eventually, he couldn't handle it from the sidelines and then grabbed Muramasa's arm.
"Okay, I know that all of you have a lot of questions for him right now, but I need to take him elsewhere for something else. Now if you will excuse me," Merlin said with a fake smile as he quickly dragged Muramasa away from Nero and her counterparts, leaving them in the dust. As Merlin was dragging Muramasa, he had a stink eye on him the entire time.
"You know, is attracting women a thing in your family Muramasa? Because from the looks of it, it sure seems like it! First, I've seen Shirou do it, and now you! Okay, maybe it's because of Shirou's body, but still! What the heck?! This is so unfair!" Merlin thought as he looked at Muramasa jealously.
"Why is Merlin looking at me like that? I haven't even done anything to him and yet he's already looking at me like I stole something from him...just why?" Muramasa thought as he looked at hum with no clue over why he looks mad at him.
Eventually, the group arrived at the cafeteria, where things were about to get even crazier.
Because in the cafeteria was Arturia, Ishtar, Parvati, Illya, Astraea, Irisviel, Kritsugu, Jaguar-man, EMIYA, EMIYA Alter, Lancer Cu, Rider Medusa, Caster Medea, Berserker Heracules, and Archer Gilgamesh.
However, instead of greeting him like usual, they instead looked at him with curiosity.
Because they noticed something different about his presence.
"Shirou?"
"Emiya-kun?"
"Senpai?"
"Onii-chan?"
"Sherou?"
"Shirou?"
EMIYA said nothing. However, he noticed something.
"That isn't my younger self over there...just what is this weird feeling?"
"Kid?"
"Shirou?"
"Boy...?"
Hercules just growled.
"Faker..."
For a moment, nothing happened. Then Arturia spoke out. "Shirou? Are you okay...?"
Muramasa let out a sigh. "My host is not here now."
"Eh? Host? Then you are-"
"Sengo Muramasa."
Everyone besides Heracules and Gilgamesh were shocked. "Eh?! Sengo Muramasa?! But how?!"
"Well...tell that to this guy here," he said as he pointed to Merlin.
Everyone then turned to Merlin, especially Arturia.
"Merlin...what have you done with Shirou here..." she muttered with her tone getting slightly angrier.
"Hehehe...let us all calm down..." Merlin nervously said.
"So let me get this straight, Merlin was interested in how both you and Emiya-kun met so that's why you're possessing his body," Ishtar said.
"Yeah."
"How is that possible?" Illya asked.
"Well it's quite simple. We just swap places for a bit. Right now, he's residing in his reality marble now."
"I see. But this is interesting though..." Astraea said.
"Yes. We're seeing senpai, but that is not senpai in front of us," Parvati said.
"Yeah. It's hard to tell if you're Shirou or Muramasa..." Jaguar-man said.
"And the voice doesn't help as well," Medusa said.
Muramasa sighed. "You're telling me. Earlier, a bunch of servants mistook me for my host earlier..."
"Really? Who?" Irisviel asked.
"Well...Musashi, some knights, a weirdly dressed girl who calls me great, great, great grandfather, and some girls that look very similar to that girl over there," Muramasa said as he pointed to Arturia.
"I see..." Arturia said.
"Still though, even though you're being called great, great, great grandfather, you still look young. What's your secret? A potion of eternal youth? Or a fountain of youth?" Lancer Cu jokingly said.
"Yeah. I'm quite interested too..." Medea jokingly said.
"Eh? You're interested in that too you old hag?" Cu said to Medea.
"Tch. I'll burn you cur," Medea said angrily to Cu.
"Hah, you mongrels are having a conversation over this lowly blacksmith...along with the faker's body," Gilgamesh sneered.
Muramasa ignored Gilgamesh's remark and then continued talking. "Anyways, does everyone here want to know the story between me and my host? Even though some of you have already heard of it."
"I don't mind," Arturia said.
"So do I," EMIYA said.
"Sure. I don't mind," Ishtar said.
"Me too," Parvati said.
"I-I want to hear this too!" Illya said.
"As do I," Astraea said.
"Me too!" Irisviel and Jaguar-man said.
"I'm interested in this story as well," Kiritsugu said.
"Finally! The story that I have been waiting for!" Merlin said excitedly.
"I want to know as well," Cu said.
"So do I," Medusa said.
"The story about the boy fusing with a heroic spirit does interest me, so I'll listen."
Hercules and Gilgamesh didn't answer.
"All right. The story is a bit short, but I'll say it anyways," Muramasa said.
Everyone stayed quiet, waiting for the story Muramasa was about to say.
"It all started after during the showdown I had against Amakusa Shirou Tokisada which involved my death upon using Tsumugari Muramasa. What happened was that after the fight, I remained as a spirit, living peacefully in the afterlife. However, that's where something unexpected happened."
"What do you mean by that?" Ishtar asked.
"Well, my sleep was interrupted by my host. What happened was that during his travels, he encountered a hidden Muramasa blade, which triggered the meeting between me and him.
"Is that so?" Parvati asked.
"Yeah. And the next thing that I knew, I woke up in a field of flowers and swords."
Merlin laughed at what Muramasa said. "A field of flowers and swords? Even though you're already dead?"
Muramasa sighed. "Anyways, when I woke in the field of flowers and swords, I noticed that there was someone else there. When I got up to see who that person was, my mind was shocked upon seeing him."
"That person was onii-chan, right?"
"Yes. When I saw my host for the first time, I had a shocked look on my face. And he did so too. In fact, I thought his face matched mine upon seeing me for the first time too," Muramasa said with a chuckle.
"I can't blame you. I mean the first time when you Sherou introduced yourself to us, we were all surprised that you look exactly like him," Astraea said.
"Yeah. Although I think the person that got the biggest shock was him over there," Irisviel said as she looked at EMIYA.
"Yeah. Even now I can't even get the idea of the blacksmith looking like my younger self out of my head..." he thought.
"Anyways, what happened was that afterwards, we introduced ourselves. It was then that I sensed that he and I were quite similar, and I thought that he was my descendant. It became even more clear when he projected a sword in front of me."
"Really?" Jaguar-man asked.
"Yeah. I'll admit, I was a little bit ticked about his magecraft at first, but I got over it later. Afterwards, me and my host had a chat and I asked him about his life. When he told me about all the stuff he did in his past and what is goal was, I was so damn impressed that I struck a deal with him."
"What kind of deal was it?" Kiritsugu asked.
Muramasa smirked. "In allowing to reside in his reality marble and studying the number of weapons he traced, I would give him knowledge of the Muramasa blades so he would trace and use them, including the Tsumugari Muramasa."
"Tsumugari Muramasa...that's your former noble phantasm, right?" Merlin asked.
"Yeah...and the same blade that beat that golden spoiled brat over there," Muramasa said with a smirk on his face.
"Why you...!" Gilgamesh growled.
"Anyways, that's the story about how I met my host, who happened to be my descendant. Hope all of you enjoyed it."
Ishtar, Parvati, Illya, Astraea, Irisviel, Jaguar-man, Kiritsugu, Merlin, Cu, Medusa, and Medea were surprised with the story Muramasa just said, Arturia and EMIYA smiled after hearing the story again, and Hercules and Gilgamesh didn't say anything.
"Wow...I did not expect the meeting between you two to go like this..." Ishtar said.
"Yeah..." Parvati said.
"Me neither. And the deal you two made, it sounds crazy..." Illya and Jaguar-man said.
"Yeah. It sounds like the deal Illya made..." Irisviel said.
"No kidding. All the knowledge about the Muramasa blades, plus a noble phantasm? That's a good deal," Astraea said.
"Yeah. Even I wouldn't pass on a deal like that," Merlin said.
"Especially the additional noble phantasm part," Cu said.
"Yeah..." Medusa and Medea said.
"Hmph, I don't see why all of you are that interested in the blacksmith's story over how he met the faker," Gilgamesh sneered.
Nearly everyone mentally groaned from Gilgamesh's remark. "Will you just shut up for once?" Cu asked Gilgamesh.
"Yeah! And why are you being rude to Muramasa?" Ishtar asked.
"Hmph. He's just a lowly blacksmith, compared to me, the king of heroes! And what's more, he's also residing in the faker's body!"
"And why does that bother you? Especially my host?" Muramasa asked.
"Because your host can copy any weapon that he sees, and that's something that I cannot permit! Only I should possess every weapon in all of history! After all, everything on this earth is my treasure! Therefore, everything should belong to me only!"
Muramasa let out a sigh. "And that's why you can't stand my host? Because you can't stand his existence?" he asked.
"Yes!"
"And why do you keep calling him faker?"
"Hmph! It's because every weapon he copies is an inferior version of my treasures! And they're nothing but just a fake! Just like him and his existence!"
At that point, nearly everyone wanted to beat the shit out of Gilgamesh for insulting Shirou and Muramasa. Especially Arturia, Ishtar, Parvati, Illya, Astraea, Irisviel, Jaguar-man, Kiritsugu, EMIYA, and Merlin.
However, Muramasa said nothing, making Gilgamesh smile.
"Well, you have nothing to say you lowly blacksmith?" Gilgamesh asked arrogantly.
For a moment, Muramasa said nothing. Then he took a deep breath and said his reply.
"Like I give a damn about what you say, you loudmouth."
Everyone was shocked at Muramasa's reply. However, Gilgamesh was not just surprised, he was also mad that Muramasa had the nerve to backtalk to him in front of his face.
"What did you just say to me you mongrel?!" Gilgamesh yelled.
"Like I said, like I give a damn about what you say, you loudmouth," Muramasa repeated.
At that point, Gilgamesh exploded.
"HOW DARE YOU TALK BACK AT ME! THE KING OF HEROES!"
"King of Heroes? Really, that's what you call yourself? Huh, well to me, you don't even act like a king of heroes. Right now, you're acting like a narrow-minded, egotistical, spoiled golden brat," Muramasa said.
"WHAT?! HOW DARE YOU! HOW DARE YOU SPEAK TO ME THAT WAY!"
"And here's another thing. You may be right about my host being a faker but let me tell you this. My host spent many years gathering those weapons and adding them to his reality marble. You on the other hand, were already born with them, so I don't want to hear any insults from a guy who already had everything handed to him on a silver platter. Not only that, but a while ago, you said my host's swords are weaker than yours because they're inferior copies. And yet, they broke your so-called treasures. What do you have to say about that?"
"WHY YOU-!"
"Also, you keep saying that everything in the world is your treasure but let me ask you this. Do you even have a Muramasa blade in that treasury of yours?"
Everyone was quiet upon hearing Muramasa's question.
"Well, do you?"
"Hmph! I'll show you! Gate of Babylon!"
Soon, golden portals appeared behind Gilgamesh. However, in a surprise turn of events, nothing came out of the portals, resulting in everyone being shocked, especially Gilgamesh.
"What?!" Gilgamesh yelled.
"Well then, guess all of the amount of talking about you saying about how you possess every treasure in the world is a big fat lie then. Because I don't see any Muramasa blade coming out of there. Then that proves one thing..."
Silence occurred.
"Only my host possess all the Muramasa blades, and you don't," Muramasa said with a smirk on his face.
It was then that Gilgamesh hit his breaking point, pulled out a sword from the Gate of Babylon, and went lunging for Muramasa, preparing to strike him down.
"How...how...HOW DARE YOU MAKE FUN OF ME, YOU LOWLY BLACKSMITH!" Gilgamesh yelled as he was about to swing at him.
It was at that moment that Arturia, Ishtar, Parvati, Illya, Astraea, Irisviel, Kiritsugu, EMIYA, and Jaguar-man prepared to draw their weapons and were about to rush at Gilgamesh...
Only to have their chances destroyed as Muramasa punched Gilgamesh so hard that he flew towards the ceiling, knocking him out as he got stuck on there with most of his body dangling lifelessly.
"What an uncivilized fellow..." he said as he brushed off his hands.
Everyone was shocked upon seeing what just happened. "Muramasa...did you just-" Arturia was about to say but was cut off.
"Punched him so hard that he went up to the ceiling? Yeah, so what?" Muramasa said.
"Well...I'm surprised that you can do this..." Ishtar said while trying to hold back her giggles from what she just witnessed.
"Yeah. That was surprising to see..." Parvati said.
"Wow, that looked like from an anime..." Illya said.
"As expected from Sherou's ancestor! The amount of grace and finesse in that punch...it's like a professional fighter's!" Astraea said as she was fangirling over Muramasa's punch.
"Yeah! Take that arrogant king! You don't mess with Shi-ah wait, Muramasa!" Jaguar-man said.
"Oh my, that was interesting," Irisviel said with a smile.
Surprisingly, Kiritsugu had a smile on his face. "Wow. That's something I don't get to see..."
"You're telling me old man. Never have I ever thought to see the King of Heroes defeated like this..." EMIYA replied as he was chuckling a bit.
"Hahahahahahahaha! No way! You actually punched him so hard he's stuck in the ceiling! This is clearly the greatest moment I have ever seen!" Cu said while laughing at the same time.
"I agree with you! My clairvoyance did not predict this great moment! Oh man, I've should have brought a camera to record this!" Merlin said as he was laughing as well.
"Don't worry, I've already recorded that," Medea said.
Cu and Merlin turned to Medea. "Show it to us later," they said in unison.
"Damn, that felt relaxing," Medusa said.
Hercules even growled cheerfully.
Muramasa sighed. "Well then, I'm going to leave now."
"Eh? Already?" Merlin asked.
"Yeah. I want to explore Chaldea a bit more."
"I see. Anyways, thanks for telling the story Muramasa!" Merlin asked.
"Hey, thank my host for that." Soon, Muramasa left the cafeteria, leaving everyone else behind.
"Now then...what are we going to do with this?" Merlin said as he looked at the body of Gilgamesh hanging from the ceiling.
For once, everyone in the room was conflicted with bringing him down or letting him stay there.
Shirou was walking in the hallway, minding his own business. It was then he heard a familiar voice.
"Mother!"
Shirou turned around to Mordred coming towards him. "Hey Mordred. What's going on?"
"Mother, can you call great, great, great, great, great, great grandfather for a moment?"
Shirou was confused. "Great, great, great, great, great, great grandfather?"
Mordred let out a sigh. "I'm talking about Muramasa."
"Muramasa? Why?"
"Because I want to hear the story of how he punched that arrogant golden asshole to the ceiling in the cafeteria!" Mordred exclaimed cheerfully.
Shirou was shocked upon hearing this. "Muramasa, just what did you do when I let you control my body?!"
And just like that, Muramasa became a legend in all of Chaldea...as the man who knocked out the King of Heroes and sent him flying into the ceiling...
11/17/20 update: Added more greats because I screwed up over when Muramasa was born.
