Crossing the vast meadows of Wales was an army, all the soldiers on horseback following their leader who was running faster than anybody else.

"Follow me, my loyal subjects, as we search for our next battlefield! Neigh!" Red Hare yelled as he led the charge, holding his giant halberd high to the sky.

"Can someone tell me why we are following a talking horse wielding a weapon?" One of the soldiers asked as he looked at the laughing horse with dead eyes, causing his companion to let out a sigh.

"Because he suddenly appeared in our camp, killed our leader, then attacked a castle and took over it, and we decided to follow him because he's strong as hell, believing that we would be able to live a life full of luxuries?"

"Oh yeah, that's right. Just how did it come down to this..." He couldn't help but mumble before he started thinking about his life.

He was nothing but a war orphan as he lost his parents in his youth because of the war and the many skirmishes happening in Britain.

In order to live, he had to resort to crimes and became a bandit along the way, and it continued for years until the mysterious horse suddenly appeared in his group's camp out of nowhere and obliterated his boss in a single blow.

His body started to shiver as he memories of the scene still lingered in his mind, the fear of facing such inhuman strength being perpetually present.

As he shook his head in order to disrupt his thoughts, he then looked at the clouded sky before he squinted his eyes, seeing something odd.

"Hey, what is that in the sky?"

"What are you talking about... what the heck is that?! Hey, boss, there is something weird happening in the sky!"

"Neigh?"

Just as Red Hare looked up, he quickly widened his eyes when he noticed a person coming down from the sky, flying in their direction at high speed with his superior eyesight.

However, what surprised the horse was that behind him was the vast amount of blue swords following him as their shines painted over the dark gloomy clouds with a beautiful azure similar to a clear sky.

And before he could give his instructions to his troops, Red Hare could only raise his weapon in order to defend himself as the flying human already reached him in a blink of an eye and blocked his blow, creating a crater under him as he tried to withstood the impact as well as a cloud of dust which obscured his vision.

With a grunt, Red Hare managed to push his attacker back before swinging his halberd around him, dispelling the cloudy dust that formed around him, then pointing his weapon at the now revealed young man.

"Hihinn! I can sense that you are a strong one! But are you strong enough to be my rider? Or will you become the subject of this Lu Bu like the others?!"

The young man just stared at Red Hare with a stunned expression, not saying anything, before he let out a snort and gave him a smirk.

"By others, do you mean the people behind you?"

"Yes, of course... Hin?" Red Hare started to say as he looked behind him, only to blink in surprise when he saw that his entire army of followers were all killed, each of his soldiers being pierced by the blue swords he previously saw in the sky.

"You know, I never kept a horse because it always hurt my ass every time I rode one. But I feel like you'd make a good pet, so prepare yourself for a good beatdown."

And when he heard the young man's words, Red Hare turned his gaze towards him again and stared at him for a few minutes. Then, he began to stamp his feet on the ground and readied his weapon in his hands.

'This destruction. This strength. This arrogance. And this mighty aura that makes my body shiver.'

Red Hare let out a wide smile as the prospect of fighting such a being made his blood boil, exciting him beyond all wonder.

Meanwhile, in Chaldea, a certain genius started to lose her mind, furiously scratching her head as she couldn't understand the scenes displayed on the monitor.

"Hey, are we really sure that this guy is really a human and not a Heroic Spirit? Just what kind of human can cross several kilometers in a single jump?! And besides, I haven't noticed it until now but why aren't we detecting anything about his magical energy when he's deploying Magecraft that can wipe out an entire army?"

"It's not only Kay, Ma'am. We can't detect anything from Merlin and the living Artoria either."

"What's wrong with them and our situation?! It's not like they are using any kind of Presence Concealment. This doesn't make any sense!"

"Da Vinci, please calm down a bit." Mash said, a bit worried about her mental state, but the genius shook her head and took a deep breath.

"Don't worry, Mash, I'm perfectly fine... I may not be Sherlock Holmes, but I'm still a genius. I'm sure that I can find out the truth about them. Perhaps the reason we can't detect anything is due to the Bounded Field that is erected across the country, which may also be the reason why Mash couldn't rayshift with Ritsuka. But then why could we detect Red Hare and the army... To begin with, how is it that he knows about parallel worlds in the first place..."

Mash could only let out a weak laugh as she saw Da Vinci mutter to herself, getting lost in her own world, before she glanced at Artoria and the other knights whose eyes were fixed on the monitor, all looking at it in disbelief.

"Even though I know this is a Sir Kay from another world, he sure is different from the one we know." Tristan said with his eyes open, a rare sight of him, while Lancelot nodded beside him.

"Indeed. While that Magecraft of his is quite impressive, able to take down an army in just an instant, I'm quite impressed with his swordsmanship. They are good and beyond what our old comrade was capable of. In fact, I don't believe I would be able to match his skills with the sword."

Lancelot's declaration shocked Mash as she knew of his status of being the best knight at the Round Table, that none could best him when it came to mastery of combat arts, so for her to hear such a statement from him told many things about Kay. She looked at the other knights to see them silent, even Mordred, which surprised Mash because she thought she was going to retort to his words or proudly boast that he wasn't that great compared to her. However, she simply remained silent, staring at the unfolding fight as if in wonder.

But the one who showed the most expression out of all of them was Artoria as she looked at her adoptive brother's parallel self with a longing gaze, her hand clutched close to her chest, an action that Bedivere also noticed as he approached her with a worried expression.

"My king, are you alright?"

"Bedivere... No, it's nothing. It's just... I was wondering if the circumstances were different, would I be living the same life as the me in this world? If history went that way, would I also be smiling as happily and innocently, just as she does. When I see her act like this, I can't help but to envy her..." She said with a small smile on her face, however, they both saw that it didn't reach her eyes as they seemed hurt.

Even Fou, who spent his time in Mash's arms, noticed Artoria's inner turmoil as he quickly jumped on her shoulder and licked her cheek, which made her giggle.

"Are you comforting me? Ahaha, thank you, Fou. I'm fine now."

And as she softly rubbed Fou's head, she then turned her eyes back on the screen, prompting Mash to do the same where she saw Kay standing over Red Hare's body with no visible injuries in sight.

[So, this is the strength of a Servant. I have to say you weren't quite what I expected but that's okay. In any case, now that I won, you're now my pet.]

[Neigh...]

'But still, is that really the power of a human?' Mash couldn't help but think as she felt there was more to Kay than met the eye.
