Soon after the bizarre event that happened in the cafeteria, Ritsuka found herself sitting in the stands in the simulator room, watching Kay standing alone in front of Mordred who was ready to brawl with him. However, she wasn't the only one as Gawain, Lancelot, and Tristan decided to join, wishing to see how different this Kay could be from the one they knew.
"Will Sir Kay really be okay, facing all of them alone?" Mash, who was sitting next to her, couldn't help wondering as she looked in worry at the line of Servants on the side facing Kay.
"It should be fine. Brother Kay is strong, he won't lose against them."
However, her worries were refuted by Artoria who was sitting a few seats away from them, eating a quick snack made by Kay with Jack, Nursery, the older Altoria and, strangely enough, a grumpy Scathach whom Kay requested to wait for a bit, something about reserving the best for the end.
And while the woman herself was unhappy about the arrangement, she allowed it if it meant that she could experience once again the fight that killed her in her life, even if her opponent was younger than the man she remembered.
"So, if I understand, once we are defeated, we won't return to the Throne of Heroes, but instead we would be sent to Chaldea's data bank where our Saint Graphs are recorded where our Spirit Origins can be reconstituted." Kay asked the group with Gawain nodding, which made him let out a small smile.
"Good. If that's the case, then I don't have to worry about killing you all by accident. So, who's coming first? Or perhaps, do you want to come all at once? I don't mind if you pick the latter." He said, eliciting a bunch of reactions from the people around.
Ritsuka and Mash could only be astonished by Kay's behavior, both thinking that he was too reckless for his own good while the other girls in the stand only smiled wistfully at his words, a smile that was shared by Scathach.
"Just as I remember..."
However, the knights didn't share their feelings as they all glared at Kay, readying their weapons.
"You shouldn't underestimate us too much, Sir Kay."
"While it's good to be proud of one's skills, there's a limit to overconfidence."
"Is this the foolishness of youth? How sad..."
"That bastard... He says that even when he hasn't drawn his sword... I'll show you what happens when you look down on me!"
With a roar, Mordred charged first at Kay like a raging bull, her body and sword both cladded in red lightning, quickly approaching the man who didn't move as he stood on his feet, smiling smugly at her. And once she was near him, she swung Clarent towards him with the intention of cutting him in half.
But then, to Mordred's surprise and that of most of the onlookers, her strike was easily blocked by Kay who suddenly wielded a translucent sword that appeared out of nowhere, one that looked very similar, if not identical, to her own.
"What..." That was the only thing she could mutter before she was repelled away and, her instincts quickly telling her to move away from Kay, quickly retreated as she barely managed to dodge Kay's sword which nearly separated her head from the rest of her body had it reached her neck.
And before she could catch her breath, she flinched when she noticed that Kay was already in front of her, his sword raised above his head which was overloaded with Magical Energy to the point she could see it was breaking apart.
'You can't be serious?!' She thought when she saw Kay bring his sword down at her, prompting her to quickly raise her sword to protect herself.
And what happened next surprised those who didn't know Kay as they all saw him fend off Mordred with ease thanks to his swordsmanship, holding the great sword with only one hand, with the Knight of Rebellion being unable to do anything but defend herself.
'He's on a completely different level from that bastard!'
Gritting her teeth and prepared to endure the pain, she overloaded her body and sword with Magical Energy before she tried to deflect his sword, which she managed to do. But before she could launch her counterattack, she widened her eyes in fear when she noticed a second sword in his free hand, already coming for her neck.
'Damn it!'
But then, she widened her eyes when she saw Gawain placing himself between the two, blocking the blow with Galatine.
"Mountain Gorilla!"
"Don't call me that!" Gawain shouted as he pushed Kay away with his flame-clad sword.
He then charged at Kay who immediately threw the Clarent-looking swords at him which he easily deflected before widening his eyes when he saw a translucent sword looking like Galatine in his hand.
"That sword...I see, it looks like you can copy any weapon you can see, am I right?" He asked Kay who only gave him a smile before their swords clashed once again, the sounds of clashing metals resonated in the simulator room.
"Neither are losing ground!" Ritsuka cried out in surprise as she watched the knights fight, neither backing down from the other, with Mash observing Kay with a confused expression.
"But Sir Gawain was said to be as strong as King Arthur when he's under the sun, does that mean that this Sir Kay was as strong as you when you were in your prime, Artoria Lily-san?" She asked the girl who nodded, wearing a proud smile on her face.
"That's right. Perhaps I should also say that I never managed to best him even once in my entire life."
The statement shocked the girls as they both looked at Kay in a new light as they saw him push Gawain back who frowned.
"It seems like I was the one who underestimated you, Sir Kay... But what about this?!"
Without further hesitation, Gawain threw his sword in the air, ready to unleash his Noble Phantasm.
"My holy sword is the embodiment of the sun. Under the king's command...?!"
As he chanted, he was surprised when he saw Kay doing the same action as him, having thrown his sword above him.
"I will burn all on the surface to the ground."
'So he can even replicate Noble Phantasms?!' Gawain thought but he quickly noticed a small detail that set them both apart, making him widen his eyes in both fear and worry.
'Of course, if he can create copies, it's no wonder he doesn't fear the risk of permanently losing his sword by transforming into Broken Phantasm... Can I win... No, don't think like that... don't be scared. As long as the sun is by my side, I won't lose!'
Gritting his teeth, determined to win this confrontation, Gawain caught his falling sword at the same time as Kay did with his own before they both shouted.
""Excalibur Galatine!!""
And like this, the area surrounding the knights was then bathed in light caused by the clash of both Noble Phantasms, prompting all people present to shield their eyes from it. And when they felt it go out, they all looked around to see the battle ground being charred to a black charcoal, bathed in fire. And to their surprise, Gawain was on his knees while Kay, on the opposite side, was standing on his feet, weaponless and uninjured.
"How can this be… Even the gorilla couldn't win…" Mordred muttered under her breath as she looked at her brother before she heard the sound of a harp being played, making her glance at Tristan who was playing his bow with Lancelot went to Gawain's side and helped him stand up.
"Are you alright, sir Gawain?"
"Yes, somehow."
"So, do you wish to continue? Or should we end this mock fight?"
Hearing Kay ask, the knights all looked at each other for a moment until they nodded as they all gathered and readied their weapons, the intent to fight being apparent to Kay and the onlookers.
"I see. Then I'll get serious."
As he said that, a small portal appeared in front of Kay and all the onlookers, except for the Artorias, only blinked in surprise as they all saw something resembling the cosmos on the other side.
"What is Sir Kay doing?" Mash spoke out loud, her question being answered by Artoria Lily who wore an excited smile on her face which was shared with her future alternate self.
"He's taking out the strongest weapon in his arsenal."
As they all saw a golden hilt show itself from the portal, Kay grabbed it and as soon as he pulled it out, they all felt both the power emanating from the weapon in his hand and how the power of Kay had suddenly risen by several folds.
"What is this sword..." Ritsuka mumbled to herself as she looked with a frown at the weapon in Kay's hand.
It was a great sword whose blade was dark blue, the shade making her think of outer space, with seven gems embedded in it which made her think of the Big Dipper.
"This is the Seven-Star Sword, the sword that brings the promise of eternal victory and a weapon said to possess the power to cleave the heavens and divide the stars. It looks like he'll start getting serious." Artoria Lily said, licking her lips without taking her eyes off Kay, prompting the girls to do the same as they saw him close his eyes, alarming his opponents.
"It's time to finish this."
"Like hell I'm going to let you do whatever you're trying to do!" Mordred shouted as she charged at Kay, her sword cladded in red lightning, with Gawain and Lancelot doing the same at his flanks. But just as they were near him, Kay only let out a smile as he looked at the knights approaching him.
"It's already too late."
In the next moment, an interdimensional vortex surged outward from Kay's feet, producing staggering waves of energy that violently pushed the knights away from him. Tristan tried to launch vacuum arrows at Kay, but they were quickly blown away because of the waves. Even those who were sitting away from the fights could feel the power emanating from Kay.
'Just what's going on...' Ritsuka thought as she stood up, looking at Kay who took a stance with his golden sword, raising it to the sky.
"My name is Kay, the Star Sword Sovereign. Under that title I command thee, Seven-Star Sword... From the sea of stars, call forth the deities of blade... Arise, Seven-Star Avatars!"
As if resonating with his cry, the interdimensional vortex beneath his feet suddenly expanded further, creating larger and more violent waves of energy that ravaged Kay's surroundings.
"Dubhe... Merak... Phecda... Megrez... Alioth... Mizar... Alkaid..."
As he recited their names, the sword gods took corporeal form behind him.
"What... in the world..."
"Well, Gawain? They look awfully tough, don't they? Well, I experienced their strengths myself since I had to beat all seven of them to gain the ability to summon them." Kay said with a grin, making Gawain grit his teeth as he could only stare at the sword gods in dread, feeling that each of them were as strong, if not stronger than him.
"Hey, that's not fair! We had problems with you alone, and now we have to fight seven other monsters like you!"
"Mordred, you seem to forget one thing... don't expect all fights to be fair on the battlefield!" Kay said as he took a stance with his sword which he infused as much as Magical Energy he could, to the point it was overflowing with it, with the avatars drawing their swords and doing the same, as if responding to Kay's gestures.
Alpha... Beta... Gamma... Delta... Epsilon... Zeta... Eta...
Seeing the sword gods recite as their swords were overflowing with Magical Energy, the Servants all tried to retreat, or at least, defend themselves from what they think will be Kay's Noble Phantasm by using their own.
"Time to end this! Astrorum Exstinctio!"
With a grand flourish, Kay unleashed a flurry of sword strikes alongside his sword gods, creating a massive wave of sword slashes flying at them at incredible speed and power.
"Like the glimmer from the surface of water...burn bright and dazzling, my sacred sword! Arondight Overload!"
"This sword is a replica of the sun. Its flame shall cleanse all the impurity of this world. Excalibur Galatine!"
"This is the evil sword that destroyed my father... Clarent Blood Arthur!"
"Song of my pain and sound of my grief. Failnaught...This is my arrow."
The four knights unleashed their own Noble Phantasms, and once again, the whole simulation room was then engulfed in a bright light because of the clash between them. But this time, Mash brought out her shield to protect the onlookers as the choc created by it was much stronger than the previous one, creating tremors across the land.
And once they all felt it quiet down, the onlookers peeked out from Mash's shield to see the arena being completely destroyed with all the knights of the Round Table lying on the ground, the only one standing being Kay himself.
"It was a good fight. It's just too bad that I'm blessed." He said as he walked in the direction of the onlookers.
"Yes! Daddy won!"
"Father is the best!"
"Alright, now I'm getting excited... Kay, as promised, it's my turn!"
"Then I shall fight him later... tonight in his bed..."
"Hey, I was first!"
As she watched the Servants rejoicing over Kay's victory, Ritsuka let out a small sigh, glad that this accident didn't end with too much trouble. However...
[Fujimaru-kun, it's an emergency! We need you to go to the summoning room as soon as possible! Something is happening over there!] She heard Romani call her through one of the room's speakers who weren't destroyed by the fight.
"Alright, I'm going right now! I'm sorry but can you all follow me?"
As she asked her Servants who all nodded, they all ran together to the summoning room where they saw it glowing in a bright light through the doors' gap as if a new Servant was getting summoned.
"What's going on? I haven't placed my shield."
[We don't know, but prepare yourselves in case it's a hostile enemy!]
As they nodded to Romani's words, they all went inside and saw, to their surprise, several Servants standing inside.
"Hi, I'm everybody's cute little sister~! I'm searching for my hubby, have you seen him anywhere?"
"I am the ruler of Britain. I ask of you, have you seen my husband?"
"Albion… Melusine… I'm searching for the man who bested me. I can smell him here, can you take me to him?"
As they all started to introduce themselves one by one, Ritsuka was utterly confused before she looked at her Servants who were the same as her, except for Kay who grew pale when he saw the one who proclaimed herself everybody's little sister.
"Sorry, Master, I have to make sure the others are alright. See ya!"
She could only blink when she saw him seemingly teleport away from his spot, leaving nothing but a crater where he stood. And then, she was surprised when the three Servants ran past her and went outside of the summoning room.
"""Wait, Kay!"""
'It looks like things are starting to heat up in Chaldea.' Ritsuka thought as she observed the new Servants running, ignoring Romani's scream happening in the background.
[Look, Leonardo! MagiMari came to Chaldea!!]
