If Kayal Hadn't Transmigrated... Then Kayal would have slowly matured, and at the age of twenty-one, he would have witnessed King Uther's demise and his final legacy: the sword in the stone! Whoever pulls out the sword in the stone shall be the King of Camelot!
If Kayal Hadn't Transmigrated... Then this plan would have caused the nobles of Camelot, who were already eager for the throne and fighting among themselves, to travel thousands of miles to the Royal Capital to try their hand at pulling the sword.
If Kayal Hadn't Transmigrated... Then Kayal would have naturally brought Atoris to the Royal Capital for this goal. For some unknown reason, Atoris, by sheer coincidence, naturally pulled out the sword in the stone in front of all the people of Camelot and all the nobles of Camelot. King Uther's bloodline naturally inherited the throne. Atoris, from then on, under Merlin's persuasion, gave up her female identity, concealed her gender, and ascended the throne.
If Kayal Hadn't Transmigrated... Then Kayal would have been angry that his attendant ascended the throne. After two years of 悶ing, he would have realized his true goal—a Knight—and re-emerged to assist King Arthur alongside his father.
If Kayal Hadn't Transmigrated... Then Lancelot, after reaching adulthood, would have been unable to bear the harassment of the foolish fairy. He would have received the blessing of demonic energy and armor and begun his life as a ranger.
If Kayal Hadn't Transmigrated... Then three years after Lancelot became a ranger, he would have returned to his hometown with a group of powerful friends to intimidate the nobles who had killed his father, King Ban of Benwick, successfully reclaiming his throne without bloodshed. Finally, under the call of the Round Table, he would have become a Knight of the Round Table. Due to his high status as King Ban of Benwick (roughly in modern Ireland) and his supreme martial prowess, he would have become the Head of the Knights of the Round Table.
If Kayal Hadn't Transmigrated... Then Kay, Gawain, and Lancelot would have become the representatives of the three major future powers of Camelot: Gawain representing the nobles, Kay representing the pro-royal faction, and Lancelot representing outsiders.
If Kayal Hadn't Transmigrated... Then Teresa would have been beheaded by Priscilla. None of these Claymores would have survived, dying one after another at the hands of Awakened Beings, the Organization, and the Abyssal Hands.
If Kayal Hadn't Transmigrated... Then the Organization would have initiated the Gemini Project five years later, instead of immediately due to the large-scale defection of Claymores and Priscilla being controlled.
If Kayal Hadn't Transmigrated... Then the world would still be turning as it was. Camelot would still be occasionally violated like a young girl—whether by the Gauls, the Anglo-Saxons, or the Romans, anyone could come and step on it... If Kayal Hadn't Transmigrated... But Kayal did transmigrate.
Although he scoffed at time theory and the box debate, based on the Schrödinger's Cat theory (the theory that one never knows right from wrong until the box is opened), Kayal did not deny that this was the historical truth of the original world. However, having completely changed this world, he also denied that the future would be the original world.
So Kayal acted without hesitation; he didn't care what the future held!
Those who focus on the future and the past are mediocre; only those who grasp the present are true heroes!
It was obvious that with Kayal's intelligence, he was certainly not the former.
So go ahead and do it boldly! This world, whatever it may be, I just want you all to know! Six thousand years ago, there was such a fellow. He might have been selfish, he might have been boring, but whenever anyone mentioned him, there was only admiration or a sigh—'Ah, so it was him!'
