Summary: Doing a Con, I buy a Saber Alter Mask, and end I up getting summoned as Arturia Alter in another world, with Mordred joining me, the both of us on the thick side.

"I take the Saber Alter mask," I said as I looked at the booth of anime periphinilia

"That will be fifty dollars," The seller answered, and with a heavy heart, I took out the money. But thankfully, it was worth it, going by the quality of the materials and from the look of it would fit around my face.

"I hope you will enjoy the experience," The man said, and I just gave him a look. I wondered if he had misspoken, but I just shook my head and, took my item, and started walking away, though as I did, I decided to see how well it would fit and put the mask on my face.

And then my vision was filled with darkness, and all sounds around me vanished.

…And then, a second later, I saw white as my vision returned, and the sound of people speaking did, but the sounds were very different.

As I did not hear the sound of a buzzing crowd but the sound of a few people speaking with tonnes of excitement and even happiness,

My vision came into focus, and I quickly noticed that I wasn't in the convention hall anymore; instead, I stood in a chamber of marble, the light of the sun shining through the glass-stained windows of the building.

And before me, I could see several people dressed in robes that kinda looked religious, with an older man with a long white beard standing in front of most of them, and around me, I saw six people dressed in mage robes, each one a different color, Red, Blue, Green, Brown, White, and Black.

Had…

Had I just been summoned for an Isekai Adventure?

"Are you the ones that summoned me?" I spoke, and after doing so, I immediately closed my mouth as it was clearly not my voice that had just spoken. No, the voice that left my voice was a clearly feminine one of almost regal stature that spoke with presence and attention.

"Yes, my Lady," The old man said as he took a step forward, and that confirmed my change of gender, which made me wonder what I looked like now. "We used an ancient ritual to call upon a person who could wield the Legendary Sword to the Sword Hero."

"Sword?" I asked in confusion, and immediately, I became aware of a weight in my hand, I looked down, and I saw that I was holding a white and golden blade in my hand with a blue gem in the center. and I also became aware of three other things.

I had rather pale skin, I was dressed in a rather familiar-looking black dress, and the top of said dress was being stretched out by a large pair of breasts.

Wait, did he just Sword Hero? Did that mean I was in Shield Hero? But I couldn't see Naofumi or the other two idiots now that I seemed to have replaced idiot number 3.

"Yes, the Legendary Sword, as it is called, is a weapon that needs to have its user be summoned; it is such for all the Legendary Weapons and its Vassals." The old man explained.

"I see, now where am I, and who are you?" I asked.

"I am Miklotov McMahon; I am the representative of the Council of Wise Men of Lugunica who asked me to perform the Ancient Ritual to summon the Sword Hero and its Vassal now that the country is suffering a crisis," Mikloto explained, and wait, Lugunica, not Melromarc? "And might I ask the name of the woman I rewho answered the call as the Sword Hero?"

I opened my mouth to answer, and a new that was not my own was spoke. "I am Arturia Pendragon. Now, what is a Vassal?" And going by the dress and skin tone, I was specifically Arturia Alter, even if my breasts were a lot larger than they should be, even if they felt natural upon my body.

"Legendary Weapon also has two Vassal Weapon users to summon them, with the Axe and Gauntlet being the Vassals for the Sword, but sadly, we lost the Gauntlet Weapon fifty years ago," Miklotov explained.

"I see," I responded. "And as far I can see, the Axe Use has not been summoned?"

"No, but they will be soon, an activated Miklotov stated.

"I see," I said as I looked over the people gathered before. "You said you summoned here to defend the Kingdom, yes? You were currently under going a crisis?"

Miklotov sadly nodded. "Yes, the Kingdom of Lugunica is suffering; the Royal Family is dead, so we have to hold an election for a new King and Bloodline, or our pact with the Divine Dragon will break, more demonic beasts roam the land before, and across the land, Demon Lords are rising and there only so many who hold the title of Hero." The man's voice was one of despair.

"And so you used one of the tools you had at your disposal to increase your military power to prevent incursion," I stated.

"You are correct; we have three direct rival nations who are landlocked, and to the east across the sea, we have the Empire, who possess a technology beyond many other nations and a navy made of metal ships," The man explained.

"I see. Is there anything you directly need me to do?" I asked.

"We are still missing candidates for the Royal Selection, so you should take the time to train Skills and make the Legendary Sword grow stronger once the Axe Hero has been summoned," Miklotov explained, and I nodded along until I caught the words he just said.

"Skills?" I asked. "I assume you don't know mean the ordinairy ones?"

"Of course not, how can you not…" Miklotov began but quickly stopped as his eyes went wide. "You are not from our world, are you?"

"You did know since you summoned me?" I asked in surprise.

"No… we just thought that the Legendary Sword would summon from one of the Kingdoms who would be best suited to think it had the power to reach beyond the Greatwater Fall…" The man said, and I guess the Waterfall was still, though its nature had probably changed as this looked to be some sort of fusion setting going by; both Rising and Re Zero were present, and from the sound of it, so was a version of the Empire from Tanya. "Well, a Sword Hero has not been summoned in almost 400 hundred years, so information has been a little lost to time."

"It seems that it does, and I have come from another world to this one, and to return to the topic of Skills?" I asked as I took a step forwards.

"Ah, yes. Skills are well skills taken beyond the norm and is represented by the system given to you by Od Laguna, the spirit of the world itself, and now that you have Legendary Sword, you should be able to view your own status without the need for a Status Sheet," He explained.

"I see, I Status?" I asked, and then, in front of me, I could see a holographic screen open up, and I couldn't help but sigh at the confirmation that this world did have a Lit-RPG system, though very much emphasis on the Lite side of things as while I could see a health bar and what looked to a be a blue mana bar there were no number next to them, no stats or 'character level' either just a title that had me labeled as the Sword Hero and a list of skills with levels next to their names.

Mana Burst LV7

Charisma LV5

Dragon Core(Inactive) LV5

Instinct LV7

Riding LV5

Magic Resistance LV7

Those were the current skills that I had on my 'Sheet' I thought the most curious one was my Dragon Core; I guess I really was Arturia, and so I suffered from shit summoning syndrome even if I seemed to have a flesh and blood body.

"Interesting, I shall look into this later, but for now, let us commence with the summoning of the Axe Hero," I stated as I exited the summoning circle and the six mages, which obviously represented the six elements of magic in this world started to set up the next summoning.

"That is a good idea; the two of you shall be working together, so the sooner, the better," Miklotov said as I took a stance beside him. "Do you think another from beyond the waterfall will be called? Though it is said, the king of Melromarc, which lies beyond the mountain, is the Staff Hero."

"Maybe, maybe not," I answered. "We will only know until the act has been performed."

"I guess so," Miklotov said back as the mages started chanting, and the magic circle that I had been summoned into started to glow as person who resonated with the Axe was summoned forth.

And with a flash of light, a person appeared and-

"What the hell just happened? What the hell was that light, and where am I!" A familiar voice shouted.

You have got to kidding me. I thought as I looked at a familiar blond-haired girl with a face similar to the one that I now bore. Though she was dressed in her causal outfit consisting of those booty shorts and that tight tanktop of hers that hugged those huge tits of hers, which, again a very different body type from normal, though considering my own enhanced Pendragon assets, it did make somewhat sense. And the sight made the heavy weight that I had been suppressing since I had been summoned it seemed to start to act up a little.

"Sir Mordred, will you please calm down," I spoke, which immediately brought the rant that had been ongoing to a screeching halt as Mordred froze and actually noticed my presence.

"Father?"

Xxx

Mordred Pendragon she had been traveling around like she usually did around Europe after the end of the Great Holy Grail War of Trifas, where, thanks to the sacrifice of her Master, he had managed to get her a body before the dragon had carried away the Grail.

And it was thanks to having a living body that didn't have her original demerits that Mordred had now started to grow physically once more.

Resulting in a body that was a lot closer to Mother's in terms of development even if she was still on the shorter end of things. Resulting in having her to get larger versions of her outfit even if it was still a little tight around her breasts.

But then, one moment, her vision was filled with light, and next, she was in some sort of cathedral with a weird Axe in her hand, and a bunch of mages around her.

She had been about to start looping of head, and then…

Father had spoken.

Father was here.

And while she looked a little different, she knew that it was Father. That her King and idol was standing before her now

And now the two of them were in a room that they had been given by the people who had summoned both of them.

"So to explain, Sir Mordred, we have been summoned to this land to act as protectors to wield powerful weapons, which are Great Spirits that can be grown to match even the mightiest of Noble Phantasms," Father explained.

"It's better; I can use Clarent thanks to this thing," Mordred growled as she had tried and immediately gotten shocked until she had to let it go, bullshit rules.

"And I can not call upon Excalibur, but we still possess the bodies of Servants even if they are flesh and blood," Father said, and Mordred was still thankful for that; she might have an inferior weapon, but she could still Mana Burst all over fools.

"And how did that happen for you, Father?" Mordred asked as going by the expanded assets, something clearly similar had happened to Father as had happened to her, though it had also resulted in her much paler complexion and yellow eyes, like the dragon aspect had brought closer to the forefront. And even so, Father was still the most beautiful being in existence, heck, Father was even more beautiful now.

"I presume you obtained flesh from a Holy Grail?"

"Yes, and then I started aging over the last two years," Mordred answered, even as she felt her face get a little flushed as she saw Father look over her body with judging eyes.

"I did the same, though the Grail in my Holy War had been corrupted, resulting in my current colors," Father answered as she put a hand through her now platinum blond hair. "And then ended up getting summoned here, which is a world much closer to the Britain of our time."

"Yeah, I went there after my War… it is Britain that could not have existed without you, Father. You truly were the best king." Mordred stated with honesty, that to see even the poorest people live like them had been amazing to actually see instead of just know.

"You no longer seek my throne?" Father asked, and Mordred immediately cringed inwardly; of course, Father had not forgiven Mordred for her betrayal and turning on the Kingdom in an act of childish tantrum as she had not understood there would be no heir, even if children had been born of Guinevere and Father.

"I still want to try and pull the Sword," She answered. "But I realized that I don't actually want the throne. I just…" Mordred had wanted her father to praise and love her, but Mordred knew that she would have never stopped wanting and would just have brought about rebellion anyway.

"I see," Father stated as a stern look crossed her father. "But we are no longer home, and I already slew you, so your punishment has been served, but Arthur Pendragon still has need of a Knight of the Round." Mordred's eyes went wide as she heard Father speak; she was surely not going to. "So Mordred Pendragon are you resume to resume your duties and serve your King and Lord in all manners?"

"Yes, Father!" Mordred almost shouted as she dropped to her knees, kneeling before the King of Knights as she placed her new blade on her shoulder.

"The rise, Mordred, you are my Knight once more," Father declared, and Mordred couldn't help but smile.

"Thank you, Father," Mordred said as she stood back up.

"Don't thank me just yet," Father said. "You might find out you got more than you bargained for."

"Ha, I can take on any threat!"
