Shirou, who returned from the Fairy Kingdom

Merlin must have met with Morgan behind her back and told her about the "cutting of the phenomenon".

In the Type-Moon universe, infinite parallel worlds can be divided into two types—

"Compiling things" and "cutting things out".

"Compilation of phenomena" represents a stable and potentially diverse world that can evolve further in the future.

"Pruned phenomena" are those that have deviated too far from the main path and become special cases, losing the possibility of most divergences. They are judged to have been completed and ended, losing the necessity to continue observing their outcome, and are worlds that are about to be "cut down".

Once a parallel world is confirmed and defined, its operation will be stopped, its possibility of development will be cut off, and all existence in the world will be completely destroyed.

Simply put, compiling events is the officially recognized main approach, while cutting out events is the approach with a bad outcome.

However, defining a phenomenon as merely "an exception that deviates excessively from the main path, resulting in the loss of most possibilities for divergence" is not necessarily a bad thing.

For example, King Arthur and Morgan joined forces to ultimately save the parallel world of Britain.

To avoid this world being judged as a "fixed phenomenon," Shirou has been trying his best to conform to the original history.

For example, the birth of Gawain and his companions. Wouldn't it be terrible if half of the Knights of the Round Table were King Arthur's biological sons?

Merlin probably predicted that "if Shirou marries Morgan and unifies Britain, the world will come to an end due to excessive deviation from its original course."

So she explained everything to Morgan and asked him to withdraw voluntarily, citing the greater good of "protecting Shirou".

"...You really do know that."

Morgan said expressionlessly, "That's right, I learned the truth about the world from Merlin."

Arthur and Morgan are destined to be apart; I am not the one who should be your wife.

Shirou, these past ten years have been the happiest days of my life.

You've given me a warmth I've never felt before, so... that's enough.

“Not at all,” Shirou interrupted her.

Morgan raised an eyebrow: "Calm down, my brother."

I understand how you feel, because I feel the same way...

It is utterly unreasonable for us to be separated by the will of history.

Don't worry, I'm not one to give in so easily.

I would never abandon you... well, if you don't mind..."

Morgan stroked the boy's cheek and said in a coaxing tone, "Even if we get married, I can still be your mistress."

I will try my best to fulfill any request you make, and I will still give birth to Mordred for you.

So... listen to me, okay?

Shirou shook off her hand: "No! Not at all! I want Morgan to be the Queen of Camelot!"

"Ha... You've always been stubborn."

Looking at her stubborn younger brother, Morgan rolled her eyes, both speechless and annoyed.

"That's just a title, I don't care about it at all."

"Don't lie, there's no woman in the world more jealous than Morgan."

Shirou's words became the fuse that ignited Morgan's anger.

"That's right! I am indeed very jealous of that woman named Guinevere! I'm almost going crazy with jealousy!"

Why should she get everything from you?! Myoshiro is my husband, my brother!

I am not reconciled, I am extremely unwilling, but—

If it's to protect you, I can absolutely endure it! I've decided to endure it!

After venting his frustrations, Morgan asked a question in return.

"Shirou, why are you so insistent on having me as your queen?"

If you want to hear me call you "my husband," I'll let you call me that as many times as you want in private.

My brother... what are you so fixated on?

What is it that you, as a person, really want?

Under the witch's critical and complaining gaze, Shirou resolutely gave the exact same answer as he had given ten years ago.

"I want Morgan to be happy."

"……………………"

Morgan covered her mouth, tears streaming down her face without her realizing it.

Even after ten years, even after becoming the King of Britain.

Even Morgan himself had long forgotten—

Shirou never forgot his original aspirations.

He came into this era so that Morgan could be happy.

……

……

--that's all.

Shirow and Morgan stood on the opposite side of "the world".

Volume 1, Chapter 104: Married Life

"Aren't you going to punish me?"

After Shirou returned to Camelot, Merlin thought he would definitely be punished this time, but he received the reply that "past offenses will not be punished".

Merlin asked in surprise, "Did you plead with Morgan on my behalf?"

Shirou shook his head, indicating that it was exactly the opposite.

"I'm still super angry right now?"

My teacher actually went to negotiate with Morgan behind my back! Your greatest strength is that you never interfere excessively!

If even this principle is abandoned, wouldn't that just be a wicked, scheming nightmare?

"Gurgle... Speechless!"

Shirou explained, "So I was thinking of teaching the teacher a lesson this time, but Morgan told me not to pursue it."

"It's Morgan...?"

Merlin looked incredulous.

She was not only Shirou's but also Morgan's guardian, so she knew Morgan's vindictiveness better than anyone else.

But this time, Morgan took the initiative to forgive himself...

Suddenly a flash of light went through his mind, and Merlin realized the truth.

"What's wrong? Why are you laughing so disgustingly all of a sudden?"

"It's nothing, hehehe."

The Flower Magician covered her lips, thinking to herself:

I'm not the only one who was changed by Shirou; Morgan was the same.

Looking back now, I realize how incompetent I was as a teacher...

He simply taught Morgan magic tricks without ever thinking of genuinely helping her, which is exactly what I, as her teacher, should do.

In the end, it was Shirou who accepted Morgan, changed Morgan, and saved Morgan.

If it weren't for Shirou, Morgan would probably have gone astray by now.

"...Thank you, Shirou, for accepting Morgan. Really...really, thank you so much."

Merlin murmured as he wiped away the tears welling up in his eyes.

"Speaking of which, Arthur."

"what happened?"

Have you ever considered taking Guinevere as a concubine?

"what?"

Ignoring the dumbfounded Shirou, Merlin launched into a long explanation of her alternative plans.

"Morgan's position as a princess and the principal wife will not change, but Guinevere will also become your concubine."

This way we can gain the Duke of Camelot's support.

Haha, the benefits of marrying Guinevere aren't just limited to getting Camelot City, are they?

Think about it...

Although the Knights of the Round Table were willing to respect the King's wishes and accept Morgan as their mistress.

However, in the future, conflict between them and Morgan seems inevitable.

Arthur, do you want the Round Table Room to become a hellish place where every meeting is a constant source of argument?

Shirou imagined it for a moment, then gasped in shock.

“At times like these, Camelot needs a mediator, and Guinevere is the best choice.”

She could effectively ease the tension between the knights and Morgan, and the Knights of the Round Table would certainly be more than happy to offer Guinevere as an object of their loyal protection, wouldn't they?

"I see……"

Shirou, rubbing his chin: Wait, isn't this exactly what the Saber group did in Fate/Zero?

To the Knights of the Round Table, Queen Morgan was like Kiritsugu, while Queen Guinevere was like Irisviel.

Seeing that Shirou was wavering, Merlin pressed his advantage: "Guinevere should be very happy, even if it's just as a concubine."

Shirou frowned: "But... Britain doesn't have the custom of polygamy, does it?"

Influenced by Roman culture, Britain has always advocated monogamous marriage.

"It's nothing. Although polygamy is somewhat incomprehensible in Britain, it allows them to do things that ordinary people can't... That's what 'My Arthur' is all about!"

Merlin chuckled as he spoke, while Shirou rolled his eyes and warned, "You'll be killed by Morgan, you know?"

The female magician said dismissively, "I was prepared to be killed long ago in order to witness your journey, Arthur."

……

……

one year later.

With the completion of Camelot Castle, Shirou, with the permission of both parties, married Morgan and Guinevere simultaneously.

As King Arthur's principal wife, Morgan von Chaumi was both the Queen of Camelot and the Queen of Britain, wielding power second only to the king.

Although Guinevere was only a concubine, she was supported by the Knights of the Round Table and loved by the people, becoming a symbol of the Camelot royal family.

Morgan and Guinevere, in their own different ways, supported Shirou as wives.

After that, there were ten years of peace and tranquility, without large-scale wars.

With Lancelot's assistance, Britain resumed trade with the continent, and port trade began to develop.

Under Gawain's leadership, the kingdom began large-scale potato cultivation, which solved the food problem and led to rapid population growth.

The story of the round table also came to fruition during this period.

As the battles with the alien races subsided, the Knights of the Round Table began to appear and resolve conflicts throughout the country.

Although they see each other as rivals and will draw their swords to fight whenever they find an excuse, they are still decent people overall.

Merlin would often take the three-eyed cat demon with him on adventures with the knights, actually in order to find a way to avoid the "fixed phenomenon".

"Call me next time too. It's been so long since I traveled with Merlin-sensei. I'm really looking forward to it."
