[You prevented Vivian and Artoria's sacrifice, replacing them with your own existence.]
[You were worthy of the title King of Britain, worthy of the legacy of Vortigern and Uther Pendragon, worthy of the expectations of your subjects. You were the most excellent, most qualified Sun-Crowned King.]
[You died.]
[Because you opened the channel between the Root and Britain, the legend of Britain continued for another three hundred years.]
[Longing for you, Morgan, Vivian, Artoria, and Merlin once again created homunculi. The birth of Gawain and others led many to believe this was a miracle you left behind.]
[After your death, Artoria inherited the throne, titled King Arthur. Britain welcomed a new dawn.]
[This simulation has ended.]
[Evaluating this life simulation... Rating is S.]
[Evaluation; You were the anomaly in Avalon, the Holy Swords' most beloved master, the source of the fairy's change, the Sun-Crowned King who prolonged the Age of Gods.]
[You were worthy of your people's expectations, even the protagonist of the world. You altered the original history, you were the greatest monarch.]
[As a king, you were excellent, but as a husband, you were inadequate. You still owed your wives. But no one is perfect, perhaps a slight regret is the best ending, isn't it?]

[Reward Obtained: Lord of the End (SS).]
[Lord of the End: You created the world, you prolonged the world, you are the world's final king. Sun-Crowned King (A) upgraded to Sun-Crowned King (S).]
[Legend of the Nation of the End: Countless subjects are willing to live and die for you. Under the King's command, a nation surpassing the Star Holy Sword will manifest once more, utterly crushing all enemies until the King's wrath is appeased.]
With the end of the final simulation, Ryuya's rating finally achieved the perfect S outcome.
As memories surfaced in his mind, he saw everything about himself: Vivian and Merlin's care, Morgan in the old castle, the eagerly awaited Artoria, the countless subjects singing praises of the King's name.
'I am... Isbel Pendragon, and also Takami Ryuya.'
Taking a deep breath, Ryuya kept these memories in his heart, completely concluding the Britain life simulation. Returning to reality, his mindset shifted back.
In this world, he was Yukino's older brother, not Britain's Sun-Crowned King.
However...
'Became a parallel world scenario? That means... I can see you all again, right? Morgan, Vivian, Merlin, and Artoria.'
The power manifesting on him was the fruit of three life simulations. But compared to this power, the memories from the life simulations were what Ryuya treasured most.
Vortigern Pendragon, who saw him as a son and sacrificed his own dreams for him three times.
Uther Pendragon, once lost in his youth but ultimately found his initial heart.
Morgan le Fay Pendragon, lonely in the old castle in every world, waiting for him.
Merlin Ambrosius, the carefree troublemaker turned fairy-aligned loli Succubus, the most ancient hikikomori with Clairvoyance.
Vivian, the Lady of the Lake, residing in Avalon as a fairy, observing the world yet drawn into it.
Artoria Pendragon, the honest, kind, brave, upright King Arthur, who desired Ryuya's love.
And finally, the countless subjects shouting the King's name, trusting the King until the very end.
This was the life of Isbel Pendragon.
And it was Ryuya's most important harvest!

A/N: Regarding the Type-Moon's ranking system, I believe anything surpassing A falls under the EX rank. For example, something slightly above A is EX, and something far above A is also EX.
However, A+ represents a multiple of A, and A++ is a multiple of that multiple power. This is the game's setting, although Nasuverse's revisions are a bit messy.
So here, I've defined the ranking system more detailedly. For instance, above A++ is S, above S++ is SS. Anything above A is EX rank, but there are still differences in strength.
Also, the skill: The King's Burden, worthy of the Heaven and Earth' is conceptually the complete opposite of the Mystic Eyes of Death Perception.
The Mystic Eyes see lines of death by connecting to the Root, while the King's Burden sees paths of life by connecting to the Root.
