Shirou, who returned from the Fairy Kingdom

Mordred holds the Clarence, a symbol of the British monarchy—

The gleaming silver sword, imbued with the father's longing, has been stained with ominous darkness by the tears shed by the sisters' fratricide.

And so, Britain entered its twilight years.

……

……

"Are you kidding..."

Mordred slowly opened his eyes and found himself lying on the damp ground.

All around were candles, a mountain of bones illuminated by their light, and something that looked like an altar with two sleeping bags beside it.

This is the magic workshop of her Master, Kairi Shishikage, located in an underground cemetery on the Sighishwara Vein.

"I actually dreamed about things from the past, what's going on..."

Mordred struggled to her feet.

The "Black" archer's shoulder throw was even more effective than she had imagined; she felt as if her whole body was falling apart.

Not only was my whole body aching, but my head was also foggy.

I think I must have fallen asleep on the way back and then been carried into the workshop by my Master.

"……Well."

Mordred remembers not only dreaming about her past life, but also having an even more bizarre dream.

What was it again? Oh, right!

I followed the trail of blood to the stronghold of the "Black" assassins, only to encounter my father there, who blew me apart with his "Wind King's Hammer".

"Haha, what an idiotic dream... How could my father appear in this era..."

Mordred chuckled self-deprecatingly.

King Arthur, as a super-status Heroic Spirit, cannot be summoned; this should be common knowledge in the world of magic.

Seriously, what's wrong with me tonight?

The blonde girl scratched her hair in dissatisfaction, then kicked the wooden door open roughly.

"Hey! Master! Why didn't you wake me up?!"

"Saber... are you awake?"

When the sunglasses-wearing uncle, Shishi Jie Li, saw Mordred, he looked completely dumbfounded.

"What? That expression... it's like they've seen a ghost, it's hilarious!"

Mordred punched his Master in the shoulder, then sat down cross-legged on the ground.

She probed indirectly, "By the way, I didn't say anything strange in my sleep, did I?"

If anyone else heard those sleep-talking remarks, Mordred would probably be so ashamed she'd want to die.

"……No."

"Well, that's good."

"...What happened?" asked Shizi Jieli.

"Hmm? Well, it's nothing."

The blonde girl put her hands behind her head and stared at the dirty ceiling.

On the way back, I had a very strange dream—

I dreamt that King Arthur, who had already reached his ideal world, suddenly jumped out and beat me up... Haha, how stupid is that?

Lion's Strike Realm's forehead twitched, his expression strange, and he hesitated before speaking:

"Um... I think... that shouldn't be a dream."

"!"

Mordred jolted awake and turned to look in the direction of his gaze—

"Oh, are you awake already?"

The red-haired boy climbed the ladder and entered the underground cemetery—

Mordred stared wide-eyed at the young face that looked like it was filled with the suffering of a woman:

"Father...King? Waa ...

The girl screamed as if she had seen a ghost, and fell flat on her face.

She crawled to a corner of the room using both her hands and feet, then covered her face with her arms.

"I...I was wrong! Please stop hitting me!"

Volume 5, Chapter 214: Joan of Arc: You're not going to act anymore now that your daughter's here?

Mordred, in a posture she had never been in since birth—hugging her knees with her arms around her chest—looked at the boy talking to her Master with mixed feelings.

She looked to be about 17 or 8 years old, and her features were quite youthful even among East Asians.

Despite his youthful face, he exudes a maturity beyond his years.

Those calm and gentle amber eyes reminded Mordred of the sunset scenery at the end of the world that she and her mother had seen in Orkney when she was a child.

how come……

It really was my father...

In other words, the starlight I saw last night wasn't Lily's, but King Arthur's...

"Really? Uncle Lion Robber, you also think Father White Hair is suspicious?"

"Yes, his servant... his real name is Semiramis, right? The oldest poisoner among humankind."

I don't think she's the kind of woman who can get along well with allies.

Ugh, what are these two doing...?

Mordred clenched his back teeth.

For some reason, the King and his Master chatted as if they were old friends.

"Yeah, that's what I thought too."

The red-haired boy nodded.

“They’re not my type, so they refused to tell me my real name.”

"Huh? Did they ask for your real name too?"

"So, you also..."

"Yes, Father Kotomine immediately wanted to know Saber's real name, but I refused."

"Oh right, Mordred also has the ability to hide her real name, which she learned from her mother."

That white-haired priest must be frantic with worry because he can't get Saber's real name.

Haha, Uncle Lion Robbery, you're so mean!

"So, you're the same way? Hahahaha!"

According to Shishi Jie Li's explanation, the father king called himself the "Black" swordsman.

Mordred was defeated by the "Black" assassin while tracking him, and then Lion's Robbery who arrived was also captured alive.

However, the "Black" swordsmen did not kill them.

After learning that Shishigaki had parted ways with the "Red" camp, he stated that he was also a free individual who had broken away from the "Black" camp.

"In that case, why don't you consider forming an alliance with me?"

The "Black" swordsman proactively extended a team invitation.

Shi Zijie Jieli felt he was already a defeated general whose life was in the enemy's hands, so naturally he had no reason to refuse or bargain.

So when Mordred woke up, the situation had become what it is now.

"Alright! The alliance is formed! Well, actually, it's not up to me... Master's approval is required."

"Huh? You don't have the final say?! Were you kidding me just now?!"

"Don't worry, don't worry, Master is very easy to talk to."

"Oh? It seems you two have a good master-servant relationship, 'Black' Swordsman."

Shiki-kai Kairi said with a smile, "I wish my Saber was as understanding as you."

"...It's so noisy."

Mordred lowered her head and bit her lip.

Normally, she would have been punched by Lion Robin long ago, but today she remained unmoved.

The young girl still didn't know how to face her father.

She had sworn to her father that she would protect Britain.

However, after her father left, she went back on her word, instigated a rebellion, and personally destroyed the country that her father had left for her and her sister.

This is something that cannot be forgiven.

Even if she is the king's most beloved daughter, it doesn't matter...

Mordred felt like she was about to cry, but she'd rather smash her head against a wall than cry in front of her father.

Just then, a hand reached out in front of her.

Mordred looked up in surprise, her eyes wide.

"father……"

The red-haired boy gave her a friendly smile:

"Nice to meet you, Mordred, the 'Red' swordswoman. I am the 'Black' Saber—"

His real name is Artorius, the Hidden Seat of the Knights of the Round Table, and King Arthur's confidant and double.

Mordred was dumbfounded: "…………Huh?"

"I heard from Uncle Lion's Robbery that there is no such person as 'Black Knight Artorius' in your world (history), so you mistook me for King Arthur, right?"

Haha, because I'm King Arthur's shadow clone, I do look a lot like the king, no wonder you mistook me for him.

What is this guy talking about?

What Arthurian legend's double, what Black Knight Artoria?

What nonsense are you spouting? There's no such person as Camelot.

Mordred could not possibly mistake her own father.

Anyone else could be mistaken, but he would never mistake his beloved father.

His eyes, his scent, his tone of voice, the shape of his soul... were all deeply imprinted in Mordred's memory.

This person is the King.

It wasn't someone who looked very similar, nor was it a stand-in or a shadow warrior.

Father...why did you lie?

Mordred wondered, puzzled, was this how he intended to conceal his real name?

That's right, my father and I are now on opposite sides in the Holy Grail War, so we can be considered enemies.

However, Mordred felt that even within the class system framework constructed by the Holy Grail, the gap between herself and her father had been greatly narrowed—

She still didn't think she could beat her father.

Therefore, there is only one reason left for him to refuse to acknowledge that he is King Arthur—

My father is unwilling to acknowledge me as his daughter—unwilling to acknowledge the child who betrayed him.
