Emiya Shirou has gone through a great of many events.

Surviving the Fuyuki Great Fire that destroyed a portion of the city he grew up in? Check.

Becoming a master in an ancient battle royale which involves the spirits of famous people despite having no knowledge of said battle royal? Check.

Meeting the soul of your ancestor who happens to be a well-known blacksmith, fusing with him, and gaining knowledge of every blade he has forged? Check.

Having two noble phantasms: which one of them is a reality marble that is considered taboo in the Clock Tower and a blade that is a recreation of a divine construct? Check.

Defeating an evil immortal interdimensional space god that can control the Akashic Records from another universe? Check, although there are times he still does not believe he has done that.

All and all, Emiya Shirou is a man who has experienced many things in his lifetime, and by now, he was ready with anything.

However, there is always a first in anything…


Shirou let out a gulp at the sight in front of him. "Wow. To think all of these heroic spirits actually came here along with master…is it really that popular around here? I mean, Da Vinci mentioned it a while ago, but I did not expect it to be this popular…"

"Shirou, is there something wrong?" a familiar voice asked.

Upon hearing the familiar voice, Shirou turned around to see Mysterious Heroine X, who was looking at him. "Hm? Ah, well…to be honest, I'm really nervous right now. To think I would be doing this in front of a bunch of well-known heroic spirits…it's quite unexpected. Honestly, I'm not sure if I can do this…"

Mysterious Heroine X let out a reassuring smile. "Don't worry Shirou, just copy the same method as what me and my counterparts did when you were in their position."

Shirou let out a nervous chuckle.

It was then that Mysterious Heroine X Alter came out of nowhere and gave Shirou a chocolate bar. "If you're really that nervous, then have some chocolate. It will help you relax."

"Thank you," he said as he graciously took the chocolate bar from Mysterious Heroine X Alter's hand.

"Hey! Eat the chocolate later! Everyone is waiting for you, so we gotta get out there and greet them!" Mysterious Heroine XX interrupted.

Shirou quickly put the chocolate bar in one of his pockets and proceeded to head out to where the giant group of heroic servants were along with the mysterious heroines. As they were walking, Shirou's mind began to recall the event that led up to this. "I can't believe that Da Vinci asked me to do this…"

(Earlier…)

"A teacher? Me?" Shirou asked in disbelief.

"Yes. I'm asking you to be a teacher," Da Vinci replied.

"Um…this is rude of me to ask, but what am I supposed to teach? And who? And why?"

Da Vinci let out a small sigh. "Well, remember that match you had against Angelica?"

"Yes. Why?"

"Simple. The 00 Raiser mystic code that you used left quite an impression on almost everyone that was watching the fight. Of course, Archer Gilgamesh was the only one that was not amused with that development, but I'm getting off-topic here. Anyways, the point is that because of how you used the gundam mystic code, Ritsuka, his counterpart, and a lot of heroic spirits were asking me for their own gundam mystic codes."

"Oh yeah, you mentioned something about pulling off a few all-nighters because of it."

Da Vinci let out a chuckle. "Yeah. However, that was not the end of it," she said as she began to take a sip out of her coffee mug before continuing. "I should have mentioned this to you earlier, but not only did they want their own gundam mystic codes, but they also wanted to learn how to use them as well. To be fair though, the sight of you flying in the air while fighting is just…well, amazing. Even I wanted to make one of my own as well."

"I see. So basically, because of my actions, a lot of heroic spirits wanted to do the same thing as I did earlier?"

"Yup. As so, since you were the only one who can use the gundam mystic code so easily, the role of teaching them lies with you. And in case you were wondering, the mysterious heroines will help you."

"I see. Wait, don't tell me they all have the same gundam mystic code as mine."

Da Vinci let out a chuckle. "Nope. They all have a gundam-style mystic code that is specifically tailored to them, so there won't be a lot of copies of the 00 Raiser mystic code."

"Fair enough. Speaking of which, who were the heroic spirits that signed up for this? Do you have a list for it?"

Da Vinci slightly turned away for a moment. "Well, let me get the list for a moment, and you are going to be surprised." She then headed towards her desk and searched through a giant mess of papers. After a few seconds, she eventually found it. "Ah, here it is," she said before giving the list to Shirou.

For a few seconds, Shirou looked at the list before his eyes nearly popped out from seeing the contents of the list.

Which consisted of all of the Knights of the Round, Kiritsugu, Morgan, Jeanne D'Arc Alter, Nero and her counterparts, Okita Alter, Musashi, Oda Nobunaga, Hakuno, Sieg, Astolfo, Ritsuka, his counterpart, and Scathach and her counterpart. Not only that, but the list also contained which gundam mystic codes they were using.

"You have got to be kidding me…" he said as he was done going through the list.

"I wish. Anyways, memorize all of this within a week."

"Wait. With all of these heroic spirits joining, we're going to need a lot of room for this."

"Don't worry. I already cleared out rooms for this."

(Back to the present…)

"Even now, I can't believe that many heroic servants actually signed up for this, not to mention that master and his counterpart joined in as well…well, let's hope this goes well…"


Ritsuka was really excited today, and the same can be said about his counterpart as well.

Why? Simple; he finally achieved his dream of being a gundam, thanks to the work of Shirou and Da Vinci. The same can be said about his counterpart as well.

"Alright! Today is the day I will be a gundam! I can't believe this is happening! Thank you Shirou and Da Vinci for making my dream come true!" he thought to himself before looking at the heroic spirits around him. "Still though…I can't believe this many heroic spirits actually came here as well. I wonder what gundam mystic codes each of them chose…"

"Hey, are you ready for this?" a nearby voice asked in a cheery voice.

Ritsuka turned to the source of the nearby voice, who happens to be his female counterpart, Fujimaru Ritsuka, also known as Gudako.

"Absolutely! Although I did not expect to see this many heroic spirits here…" he said as he looked around to see the various heroic spirits around him. "I mean, I see the Round, Kiritsugu, Morgan, Jeanne D'Arc Alter, Nero and her counterparts, Okita Alter, Musashi, Oda Nobunaga, and even Scathach and her counterpart!"

"I know. I can see some of them doing this, but Scathach and her counterpart? That's unexpected," Gudako replied.

"Yeah. I did not know she was interested in this. And speaking of which, I see Morgan in the crowd as well."

Ritsuka chuckled sheepishly. "Me too. Imagine my surprise when she decided to come along with me."

(With the Knights of the Round…)

Mordred looked angrily at Morgan, who was in the distance. "Damn it, she's here as well. Just what kind of plans does she have here…never mind that, today's the day I use the same mystic code as my mother's…"

It was then she felt a hand on her head. "Mordred, calm down when you see her."

Mordred let out a sigh in annoyance. "I know, but her face makes me mad every time I see her. Even though she may be from a different timeline, the sight of her just…you know."

Knowing Mordred's words, Gawain decided to change the topic. "Anyways, what gundam mystic code did you receive, Mordred?"

"Huh? Like I would ever tell you!" Mordred replied.

"Mordred…" Gawain said with a groan.

"Leave her be Gawain. She doesn't want to reveal what gundam-mystic code she plans on using. Not until Queen Shirou arrives at least."

Gawain sighed. "You have a point there."

"Wow! I can't believe we're going to learn how to fly!" Gareth said excitedly.

Percival let out a smile. "You seem excited about this, Gareth."

"Yes! After all, we're going to be joining Queen Shirou in the skies soon! I can't wait to be with the clouds!"

"I agree with you," he said before he turned to Agravain. "Still though, I can't believe you actually joined us for this, Agravain."

Agravain let out a sigh. "As much as I don't want to admit it, but that mystic code seems to be quite effective in battle based on that demonstration we saw earlier."

"Eh? You don't have any interest in flying?"

"Like I would care about that, idiot."

"Really? You don't care about the feeling of the wind flowing to your face or the feeling of floating in the air?" Tristan asked.

"Why should I care about the feeling of being in the air? It's pointless. All I care about is how effective it is. That is all."

Tristan sighed. "Jeez, you need to be a bit more carefree and learn to indulge in the simplest things, or else you'll never understand the dreams of men…"

Meanwhile, Morgan was just waiting patiently for the main event to start. "Hm…the power of these gundam mystic codes seem to impress my husband…maybe I should test them out to see if they're worth his attention…"

"Yahoo! We're going to be gundams!" Astolfo said with excitement in his voice.

"Astolfo, you seem quite excited about this," Sieg said calmly.

"Really now? After what happened when we saw Shirou just did with his own gundam mystic code? There's no way I'm passing on an opportunity like this!"

"I see. I just hope this lesson goes well…"

"Relax! We already have four teachers here, so I'm pretty sure that nothing wrong will happen here! Well…aside from accidental blasts of course, ehe," he said before turning to Jeanne D'Arc Alter. "And it seems that Jeanne's altered little sister has joined us as well!"

"Tch, you don't have to yell that out loud…" Jeanne D'Arc Alter grumbled.

"So, what are you doing here? Are you interested in this as well?" Sieg asked.

"Well…I just want to make that woman pay…and make her jealous…"

Sieg was confused with what Jeanne D'Arc Alter said, but Astolfo knew what she was talking about. "I see! You don't want your rival to leave you in the dust and want to be on the same level as Emiya Shirou, who you have a crush on!"

Jeanne D'Arc Alter blushed. "C-CRUSH?! I DON'T HAVE A CRUSH ON HIM!"

"Crush? What do you mean?" Sieg asked, confused with what was going on.

"Well-"

"DON'T SAY ANY MORE!"

"Wow. They seemed to be fired up over there…" Musashi said as she looked in the distance.

"Yes…speaking of which, when is the lesson going to start? I want to fly like Shirou…" Okita Alter said while raising her hands in the air.

Musashi chuckled. "Be patient and wait," she said before looking at Oda Nobunaga, who happened to be nearby and was also impatient as well. "And it seems you are not the only one who is not patient about this event, right Oda Nobunaga?"

"Exactly! The opportunity to wield the same power as Emiya Shirou is an opportunity one should never pass on! This power is worthy of being used by me, the sixth demon king of heaven! Hahahahahaha!"

Musashi let out a small sigh. "So, what gundam-style mystic code did you receive?"

Oda Nobunaga let out a grin. "Oh, I'll show you when the lesson starts! And trust me, it's so amazing that it will knock your socks off!"

"Really? It's that amazing?"

"Yes!"

"Wow. Looks like I have something to wait for."

"So do I!"

Oda Nobunaga turned around to see Nero, who was with her counterparts. "Ah, Nero! I see you have joined as well!"

"Umu! After what happened with my praetor and his majestic gundam mystic code, I can't help but want one of mine as well!" Nero exclaimed in excitement.

"Indeed! He left quite an impression on us! Especially with how majestic he looked in the air!" Caster Nero replied.

"Exactly! The beauty of that gundam mystic code in his possession is magnificent!" Bride Nero said.

Meanwhile, Scathach and her counterpart were examining the crown and the various reactions. For the most part, they were quite amused with the reactions. "Well, everyone here seems to be so interested in the mystic code Emiya Shirou used and now wants lessons on using it, including us as well. Not to mention the various servants who came here as well. I see master and his counterpart, the Knights of the Round, Nero and her counterparts, Oda Nobunaga, Emiya Shirou's father, and two of Japan's famous swordsmen, or swordswomen in this case."

Scathach Skadi let out a chuckle. "Can you blame them? Emiya Shirou demonstrated the abilities of the gundam mystic code he received from Da Vinci, and they proved to be quite exceptional in battle. It's a given that everyone wants their own at this point."

"Yeah. I'll admit, even I'm impressed by its abilities and wanted to try them out on my own, especially the flying part. It's really useful in every situation," she said with a devious grin on her face.

"Oh? That look on your face…you're probably thinking of a new training menu for your student and his counterparts?"

Scathach's grin grew even further. "Maybe."

It was then everyone in the room started to quiet down when Emiya Shirou along with the mysterious heroines came into the room. As they arrived, Shirou was really nervous with the large crowd in front of him.

Meanwhile, a surge of anger swelled inside of the mysterious heroines when they noticed Morgan in the crowd. "Shit. Morgan's here as well…I need to keep tabs on her…" they thought in unison.

For a moment, the entire room was silent before Shirou gave his speech. "Okay, now I was told by Da Vinci that everyone here has their own gundam mystic code because of me, and are asking for lessons on how to use them," Shirou said before he cleared his throat. "Now, this is my first time teaching all of you here, so I brought in some help."

On cue, the mysterious heroines began to speak out.

"Now, I'm pretty sure that everyone here already knows who we are, so there's no need for formalities. However, there is one thing I will say about these lessons is that you will need time to learn how to use your own gundam mystic code!" Mysterious Heroine X said.

"Exactly, so don't expect to figure all of this out so easily. It took Shirou quite some time to learn how to use his gundam mystic code effectively too," Mysterious Heroine X Alter said.

"Not only that, but the training here is quite hard, so if there is anyone here who wants to back out, now would be a good time!" Mysterious Heroine XX said.

However, nobody left the room, symbolizing the crowd's desire to learn to use the gundam mystic code.

"Alright. Now that's has been settled, lessons will soon begin," Shirou said.

That got everyone's attention.

"However, since there are a lot of people here, we'll be dividing everyone here into groups. Let's see here…group one consists of me, the Knights of the Round and my old man. Group two consists of Mysterious Heroine X, master, master's counterpart, Morgan, Sieg, and Astolfo. Group three consists of Mysterious Heroine X Alter, Hakuno, Nero and her counterparts, and Jeanne D'Arc Alter. Lastly, group four consists of Okita Alter, Musashi, Oda Nobunaga, and Scathach and her counterpart. Not only that, but we will also be going into separate rooms. Any questions or problems with this?"

Everyone did not have any problems with the arrangements, so they did not say a thing.

"Alright then, get into your groups. That's all," Shirou said as he separated himself from the mysterious heroines. However, he was stopped by Mysterious Heroine X as she put a hand on his shoulder.

"Good luck," she said with a soft smile on her face.

"Yeah."

Soon, everyone split into the various groups they were assigned to and they went into separate rooms so each group could have their own space. Soon, only Shirou's group remained. "Now then…let's begin the lesson."

"Yes, Queen Shirou!" nearly all of the Knights of the Round replied. Only Agravain did not reply while Kiritsugu let out a shrug.

"Alright." Shirou then went through the list Da Vinci gave him. "So… judging by the list, Mordred received the 00 Gundam Seven Sword mystic code, Gawain has received the Load Astray Omega Gundam mystic code, Lancelot has received the Sword Impulse Gundam mystic code, Tristan has received the Cathedral Gundam mystic code, Bedivere has received the Gundam Exia mystic code, Gareth received the Pale Rider Dullahan mystic code, Percival received the Gundam Kimaris (Booster pack) mystic code, Agravain received the Strike Noir Gundam mystic code, and my old man received the Cherudim Gundam SAGA mystic code…Da Vinci, you really did give them mystic codes specifically tailored to them…"

After a few seconds of silence along with looking at the specs a bit longer, Shirou began to speak up. "Okay, now that I have a good view of all of the specs of the gundam mystic codes each of you possess, I have some news about some of you."

Nearly all of the Knights of the Round (aside from Agravain) were ecstatic to hear the news. Even Kiritsugu smirked behind his mask. However, Shirou's next words began to bring shock to some of the people in the group.

"Gawain, Lancelot, Gareth, and Percival, your gundam mystic codes can not fly in the air on its own."

Gawain, Lancelot, Gareth, and Percival were shocked upon hearing those words. "Eh?! Our gundam mystic codes can not fly?!" Gawain yelled.

"Sadly, yes."

"Why?!" Lancelot asked.

"Well, according to the data Da Vinci gave me, all of your gundam mystic codes can only operate in land and space. However, Percival's gundam mystic code can fly, although for a short time. I'm sorry about that."

For a moment, all four knights were slightly disappointed that they could not fly in the air like Shirou could.

"Aw...I want to fly like Queen Shirou..." Gareth muttered in sadness.

"Ah, well, what's done is done. Nothing can be changed about it," Percival replied.

Shirou let out a sigh as he was relieved that they took the news well before turning to the others. "Now then, Mordred, Bedivere, Agravain, and old man, your gundam mystic codes have the ability to fly. Furthermore, Mordred's, Bedivere's, and my old man's gundam mystic codes have the Trans-Am system, so they will be receiving extra training on how to use it properly so they won't crash into things."

There was a short moment of silence before Mordred continued the conversation in anticipation. "Trans-Am system…you mean-"

"Yes Mordred. It's the name of the system that allows me to do what you saw on that day."

At that moment, Mordred burst in excitement. "Yes!

"Alright. Now then, bring out your gundam mystic codes."

The Knights of the Round and Kiritsugu began to bring out their mystic codes, which took the forms of various gundam weapons.

Mordred brought out the GN Buster Sword II.

Gawain brought out the Load Long Sword.

Lancelot brought out the Excalibur anti-ship sword.

Tristan brought out the beam buster rifle.

Bedivere brought out the GN Sword.

Gareth brought out the heat lance.

Percival brought out the Gungnir.

Agravain brought out two "Shorty" beam rifles."

And Kiritsugu brought out two GN beam carbines.

Shirou was surprised by the gundam mystic codes. "Wow. These gundam mystic codes clearly match them…" he thought to himself. "I suppose all of you know how to activate them?"

Without any need of words, everyone in the room activated their gundam mystic codes, turning them into gundams. "Well then, I guess I'll do the same thing then." In an instant, Shirou traced his 00 Raiser mystic code and activated it as well, giving him the form of the 00 Raiser, but human-sized. "Okay, now, the first thing I'm going to teach all of you is how to fly, or jump really high in some people's cases."

"How do we do that, Queen Shirou?" Gawain asked.

"Well…as ridiculous as it sounds…imagine yourself flying," Shirou replied.

At that moment, everyone looked at Shirou with shock in their eyes. "What?" Lancelot asked in disbelief.

"Yes. Imagine yourself flying, or jumping in some cases."

For a moment, nobody did not say or do anything until Mordred started to chuckle before turning to laughter. "N-No way! Y-You're telling me that in order to fly, just imagine yourself flying? That's the most childish thing I have ever heard!"

Shirou let out a small pout. "Believe, as childish as it may sound to you, that's the advice Mysterious Heroine XX said to me."

Upon hearing Mysterious Heroine XX, Mordred suddenly stopped laughing.

Soon, everyone followed Shirou's directions…and it went into chaos.

Because somehow, they immediately hit the ceiling the moment they started to float in the air, or in Gawain's, Lancelot's, Bedivere's, and Gareth's case; jump.

Shirou let out a sigh. "This is going to be a long day…speaking of which, I wonder how the others are doing…"

(With Mysterious Heroine X…)

"Come on! Is that all you got!" Gudako yelled as she threw a punch at Ritsuka in her Extreme Gundam mystic code.

"Tch! I'm not done yet!" Ritsuka replied as he threw a punch back at Gudako in his Extreme Gundam Type-Leos mystic code.

Meanwhile, Morgan was looking at Ritsuka fighting against Gudako with interest in her eyes. "Ho? So this gundam mystic code seems to improve my husband's physical capabilities…how interesting…in that case, I'll give it a try."

In an instant, Morgan turned into the form of the Gundam Halphas. As she did, she began to fly around in the air. "Ho? I'm already flying without the use of magecraft…this seems useful."

At the same time, Mysterious Heroine X was keeping tabs on Morgan. "Morgan, you better not do anything to master or Shirou…speaking of which, why are you even here? Do you really have an interest in this?"

"Yahoo! Flying in the air feels really good! Especially if you're the one doing it yourself!" Astolfo exclaimed happily as he was flying in the air in his Xi Gundam mystic code without any care.

"W-Wait up Rider! I'm not used to this yet! Not to mention I still don't know how to turn into mobile armor mode!" Sieg replied as he was flying behind Astolfo in his Gundam Epyon mystic code.

Mysterious Heroine X let out a sigh upon seeing Astolfo's antics in the air. "Jeez, Astolfo can be really carefree sometimes…"

(With Mysterious Heroine X Alter…)

Hakuno was flying in her Destiny Impulse Gundam Blanche mystic code mystic code. "It's quite impressive actually. Honestly, I could get used to this, although I really need to work on my aim…"

Meanwhile, Nero and her counterparts were observing Hakuno from the bottom while testing out their own gundam mystic codes as well. "So this is the power of a gundam! Amazing!" Caster Nero said in amazement as she was observing the abilities of her Rose Gundam mystic code.

"Umu! I can see why master wanted one of these to begin with! They are quite exceptional to use!" Nero replied as she was swinging around the giant heat sword of the Red Rider mystic code. "And these weapons are quite extravagant too!"

"Indeed! Not to mention how easy it is to use them!" Bride Nero replied as she was flying around in her Strike Rogue Ootori mystic code.

"Hm…black, red, and a bit of yellow…goes well with me. And the name Black Wing…a bit cliche, but sounds a little cool at least. I wonder how powerful this twin buster rifle is…"

However, when Jeanne D'Arc Alter pulled the trigger, a huge blast came from the twin buster rifle, making her fall backwards in the process. At the same time, it created a giant hole in the wall, making everyone stop for a moment in shock.

"Wow…this gun packs a punch! Now I can surely beat that woman!" Jeanne D'Arc Alter thought in amazement.

"Ah…Da Vinci is going to be mad at me later…" Mysterious Heroine X Alter thought.

(With Mysterious Heroine XX…)

"Ora ora ora ora! Come on Okita Alter! Surly you can do better than this!" Musashi yelled as she was swinging the Gerbera Straight and Tiger Pierce katanas from her Gundam Astray Red Frame Kai mystic code at Okita Alter.

"Tch. Don't worry, I'm not ready to give up yet," Okita Alter replied as she kept blocking Musashi's sword swings with her own Gerbera Straight katana from her Gundam Astray Red Frame (Flight Unit) mystic code.

Mysterious Heroine XX looked at both Okita Alter and Musashi with satisfaction. "Alright, looks like I have nothing to worry about Okita Alter and Musashi.,,but Oda Nobunaga…"

As on cue, a huge blast was heard, forcing Mysterious Heroine XX to look around. As she did, she saw Oda Nobunaga, who was floating in the air with her Legend Gundam mystic code and was laughing at the same time.

"Hahahahahaha! So this is the power of the Legend Gundam! Excellent! Hahahahahaha!" she yelled as she admired the firepower of her gundam mystic code.

Mysterious Heroine XX let out a sigh. "I have a feeling she's going to be one crazy student…"

Meanwhile, Scathach and her counterpart were observing the actions of everyone else aside from them. "Oh, it seems everyone here is having fun with their gundam mystic codes," Scathach said.

"Yes, but doesn't that apply to us as well?" Scathach Skadi replied. "After all, we did join this class and received our own gundam mystic codes."

Scathach chuckled. "You're right. Speaking of which, let us join in the fun, shall we?"

"Indeed."

Soon, Scathach and her counterpart activated their gundam mystic codes. As their transformations were complete, Scathach was in the form of the Gundam Gripe while Scathach Skadi was in the form of the Nix Providence Gundam.

Soon, both servants readied themselves for a fight.

"Now then…let's fight!"

And both of them charged towards each other.


Shirou let out a sigh as he slumped his head on a table in Chaldea's cafeteria. "Man, I am so tired right now…"

"Jeez, you look like a mess right now," a new voice said.

Upon hearing the new voice, Shirou forced his head off the table to see the source of the voice. "Waver-sensei…"

"Just call me Waver now, Emiya Shirou," he said as he sat down on a chair next to him. "So, I've heard that you've been teaching other heroic spirits on using their gundam mystic codes, right?"

"Yes…and it is exhausting. Teaching all of those people tired me out…" he said with a sigh of exhaustion.

Waver let out a bitter chuckle. "That's what a job of a teacher is. Every day, you have to go to a room filled with other people and teach them. Not only that, but you also have to answer every question they ask you. Speaking of which, who were your students for this?"

"...The Knights of the Round and my old man."

Waver's eyes nearly popped out for a moment. "You're kidding me. The entire Knights of the Round and the counter guardian version of the magus killer were your students?"

"Yes, and that was only the portion I had to teach. Before the lessons started, there was an even larger group that arrived. We had to split the group into smaller groups to lessen the stress."

Waver was silent before continuing the conversation. "Just who was in that group?"

Shirou sighed. "Master, his female counterpart, Morgan, Jeanne D'Arc Alter, Nero and her counterparts, Okita Alter, Musashi, Oda Nobunaga, Hakuno, Sieg, Astolfo, and Scathach and her counterpart."

Waver was in disbelief. For a moment, his mind was trying to come up with a response with the ridiculous answer Shirou just gave. "Jeez…that's a crowd. And you're telling me that all of those heroic spirits want their own mystic codes and learn how to use them?"

"Yes…"

"Jeez, and I thought I had it hard teaching my students, but this…this is just insane. You're practically teaching well-known heroes how to become gundams. This is something unheard of."

"You can say that again. Honestly, this is something I would not expect to do in my lifetime."

"Definitely. So, how did the teaching go?"

Shirou sighed again. "It was really chaotic..."

(Earlier...)

"WHOA, WHOA, WHOA!" Mordred yelled as she was flying uncontrollably in the air with her 00 Gundam Seven Sword mystic code.

"Mordred! I told you not to activate the Trans-Am system this early!" Shirou yelled.

"WHO CAAAAARRRRREEEEESSSSS!"

Shirou let out a small sigh before hearing an argument in the distance.

"No, my mystic code is better! It has two swords and two boomerangs!" Lancelot argued.

"No, mine is better! My sword has multiple forms!" Gawain argued back.

Shirou was shocked at the argument Gawain and Lancelot were having. "Wow, those two are really getting heated up, and just to see whose gundam mystic code is better. I wonder how are the others are doing..."

It was then Shirou looked at Tristan, who was struggling with his gundam mystic code...in the form of him running towards at what seems to be a combination of his backpack and weapons.

"Hey! Get back here!" Tristan yelled.

Shirou sighed and then turned around...only to see Percival barfing on the ground. "Percival?!"

Upon hearing Shirou's voice, Percival quickly replied. "Hey Queen Shirou...sorry for seeing me in such a state," he said before barfing again.

"Uh...what happened?"

"It seems...I went too fast..." Percival replied.

"I...I see...h-how is Gareth by the way? Wasn't she with you?"

"Well..."

"Queen Shirou! How do I turn off the heat lance again?!" Gareth yelled.

Shirou turned around to see Gareth...and a bunch of holes around her. He let out a sigh. "That's a lot of holes here...at least things couldn't get any crazier..."

"Hey, someone get me down from here."

Upon hearing the voice, Shirou turned around to see Agravain hanging in the air with one of the Rocket Anchors stuck in the ceiling. Shirou let out a small sigh before turning to Bedivere. "Bedivere, can you help get Agravain down?"

"Yes," Bedivere replied as he stopped what he was doing and went over to where Agravain was.

"Wow, I can't believe Agravain actually got himself stuck in the ceiling. What's next?"

At that moment, there were explosions in the room, forcing everyone to stop for a moment to see the smoke in the room. When the smoke cleared, everyone saw Kiritsugu in his Cherudim Gundam SAGA mystic code along with a circle of explosion marks around him. For a moment, nobody said anything.

Then Kiritsugu cleared his throat. "Well then, that did not go so well."

"Old man..."

(Back to the present...)

"And that's how it went."

Waver was completely stunned at Shirou's recalling of his lesson. "So let me get this straight. When they asked you how you fly, you told them that you imagine yourself flying and Mordred started laughing at how childish it sounds. However, she immediately stopped upon hearing it was Mysterious Heroine XX's idea. Then when they did the same thing you did, they went too fast in their take off and hit the ceiling in the process. Not only that, but during the lesson, Gawain complained that Lancelot's gundam mystic code has two swords instead of one, which sparked an argument between the two over whose gundam mystic code is better, Tristan was chasing after his backpack which can turn into a mini spaceship, Gareth had a hard time controlling her weapon and ended up making multiple holes everywhere, Percival had trouble adjusting to the speed of his gundam mystic code and he ended up vomiting, Mordred tried to use the trans-am system without your permission and ended up crashing all over the room, the Magnus Killer accidently dropped some bombs on the back skirt of his gundam mystic code and nearly blew himself up, and Agravain got himself hanging on the ceiling?"

"Yes," Shirou replied.

"Wow. That's a lot of trouble. Wait, what about Bedivere?"

"Well, surprisingly, Bedivere seems to be getting the hang of this."

"Huh. At least something good happened, although I'm still a bit shocked at what happened to your old man. I mean, he nearly blew himself up."

"You can say that again. Not to mention the fact that Da Vinci practically gave my old man an armory. There's literally guns mounted on the legs, shoulder, and the backpack."

Waver groaned. "Of course, give the man known as the magus killer more weapons to use…and replace the bullets with beams at the same time…" he thought to himself before he got out of his seat to get some water. After a few seconds, he returned back to his seat with two cups of water. "Here."

"Thank you," Shirou replied as he grabbed one of the cups and drank out of it.

"No problem. So, how was it being a teacher?"

"Honestly, it was unexpected, but quite fun actually. I did not expect to teach a bunch of heroic spirits to become gundams, but the experience was quite enjoyable, although exhausting."

"Heh, you seem to be enjoying being a teacher, despite the shortcomings it comes with," Waver said with a chuckle on his face. "I wish I had your optimism during my first days as a teacher…"

"Yeah, although sometimes I feel like I'm screwing up on teaching them."

It was then that Waver slapped Shirou on the back. "Relax, you didn't do anything wrong here. In fact, having some doubts on the first day of teaching is normal. Trust me, I've been through that situation so many times."

"I see. Do you have any tips on teaching?"

Waver let out a sigh. "Shirou, there are no tips on teaching. Ironically, being a teacher means you have to learn new things from your students. All you can do is to adapt and move on."

"Huh. Thanks for the advice Waver."

"No problem."

At that moment, three people came into the cafeteria with an exhausted look on their faces.

"Man, I am so tired!" Mysterious Heroine X moaned.

"I…need…sweets…" Mysterious Heroine X Alter moaned.

"I need…extra pay for this…" Mysterious Heroine XX moaned.

"Wow, now that's what I call overworked…" Waver thought in sympathy as he looked at the three heroines, which were walking towards where Shirou was.

"Shirou…we're tired…" they moaned in union.

Shirou let out a sigh. "This is going to be a long few weeks..."


Time has passed since the first day, and progress has been going smoothly.

"Alright, it's been a few weeks since all of you received your gundam mystic codes and started training with them. If there's anything I have to say, good job for all of you for mastering your gundam mystic codes."

Almost all of the Knights of the Round let out a cheer. Only Agravain and Kiritsugu did not have any reaction.

"However, despite these gundam mystic codes you have all received, do not mistake it as your own or abuse its powers. Abusing its powers will end in the confiscation of your gundam mystic code. Understand?"

Everyone nodded in reply.

"Good. Now then, since today is our last day training, I might as well make our last day together a bit interesting."

Everyone was quiet for a moment.

"Everyone…attack me at once."

Nearly everyone's eyes popped out from hearing Shirou's words. "Eh?! You want all of us…to attack you, Queen Shirou?" Gawain asked.

"Yes. As crazy as it sounds, I want all of you to attack me."

"W-Why?!" Gareth asked.

"Well, since all of you have grown in figuring out how to use these gundam mystic codes, I figured why not put this to the test to see how much all of you have grown."

Everyone was stunned by Shirou's words.

"Well…in that case, we won't hold back, Queen Shirou," Percival said.

Shirou let out a smirk. "Very well, bring it."

"You heard mother! Don't hold back on your gundam mystic codes! Let loose as you wish!" Mordred yelled as she brought out her GN Buster Sword II.

Soon, everyone else did the same thing as Mordred and turned into their gundams. Soon Shirou did the same thing as well.

"All right…let's begin!" Shirou yelled.

And at that moment, Shirou was in a gundam fight of his own as he clashed with the Knights of the Round and his adoptive father as gundams...


Omake

Cu felt like he was in hell. No, he was sure he was definitely in hell, along with his counterparts.

And that hell was in the form of running away from Scathach, who was flying in the air while wearing the Gundam Gripe mystic code.

"Come back here, Setanta!" she yelled as she threw the beam spear at them with great force and accuracy.

"DAMN IT KID! WHY DID YOU GIVE HER THE ABILITY TO FLY NOW?! THANKS TO THAT, YOU CREATED OUR WORST NIGHTMARE!"
