A 17-year-old boy was lying on the floor of a burning temple. His blond hair was dirty with dust and ashes. His torn clothes were stained with blood and burned by the fire that enveloped the Ryuudo Temple.
He lifted his eyes from the ground and looked at his opponent; his eyes burned with an unshakable determination that even his opponent had failed to break with his noble phantasm.
"We're at the end, faker," Gilgamesh said, approaching the boy menacingly.
His hair sparkled like gold, and his red eyes glowed like the crackling fire that was slowly devouring the temple. He only wore the lower part of his golden plate armour, leaving the upper part exposed and revealing a Vitruvian body adorned with red tribal tattoos.
"Since you've offered me decent entertainment, I'll allow you to say your last words," he said.
Yuto smiled very slowly confusing the man. "This is kind of you, your Majesty," he said sarcastically. "Then, I order you with a command seal! Come, Saber!"
The Command Seals on the back of his hand glow and one of them disappeared. Gilgamesh did not realize immediately what was happening, giving an opening that the boy decided to use in his favour. He took control of some swords that were scattered on the ground and flew them against Gilgamesh, causing him to move back a few steps.
A knight covered with heavy silver and red armour and a helmet that made her menacing and dangerous appeared through blue mana particles. She wields a white silver sword decorated and glittering adorned with beautiful decorations.
Saber threw herself toward Gilgamesh, aiming her sword at the man's throat. Gilgamesh opened a golden gate from which a chain came that blocked Saber's movements.
Enkidu, the Chains of Heaven. One of the many Noble Phantasm possessed by the King of Heroes and the chains that can keep even the divinities locked.
"I admit it was clever to use a command spell to summon your servant," Gilgamesh recognized while opening several gates which were ready to shoot against the Saber Class Servant. "Unfortunately, this is not enough to save you."
He fired a barrage of weapons at the servant, but Yuto protected her up by projecting a black-crossed shield.
"Galahad."
Yuto stretched his arm in front of him. The ghost of a handsome, white-haired knight appeared beside Yuto and nodded in agreement. A magic circle widened in front of the shield, and a holographic wall appeared, blocking the enemy's noble phantasms.
"Did you defeat Berserker?" Yuto asked his servant.
Saber walked next to her master. Her helmet began to dismount revealing her face. She has wheat blond hair and emerald, green eyes and looks identical in every way to her master except the gender that was a girl.
Her name was Mordred Pendragon, the bastard "son" of King Arthur, the King of Knights, and the Knight of Treachery who caused the fall of Camelot and the death of King Arthur on the hill of Cammlan. However, she was not King Arthur's only child because she discovered that she had a half-brother from her "father's" side and that half-brother was her master.
Her master's name is Yuto Pendragon, and he is the son of Shirou Emiya and the Saber Servant Class of Fifth Holy Grail War, AKA Artoria Pendragon.
Yuto did not know what happened at the end of the Fifth Holy Grail War, but his mother remained on earth after she destroyed the Holy Grail and her contract with the world was dissolved. She married his father and Yuto was born from their union. However, they both died to save his life from Gilgamesh, the same person that Yuto was challenging right now, although only recently the magus found out that Gilgamesh was only the executor. The whole mind was Morgan Le Fay, Artoria's older sister, the mother of her sister Mordred and Yuto's aunt.
It was difficult work, but he was Lancelot after all," Mordred replied observing the man in front of her. "Instead, I see that you have a problem taking out the trash."
"If I had killed him before you were done with Berserker, you would never have spoken to me again," Yuto replied sarcastically.
"You are right," Mordred nodded, grinning.
Meanwhile, Gilgamesh yawned as he watched bored while listening to the speeches between his last enemy and Saber. "Are you done talking, Mongrels?" he asked wearily.
The siblings turned and frowned at him.
"What's your problem, huh? Does the King of Mongrels dislike being ignored?" Saber said arrogantly, prepared to resume the battle.
The King of Heroes made an irritated grimace at Mordred. He opened dozens of doors from which swords, axes, spears and so on exit from them. "You will regret your insolence, mongrels!" he growled.
"Trace on."
With a single glance, Yuto copied all the weapons that came out from the Gate of Babylon and fired at the originals. The two series collided with each other, causing metallic sounds and sparks. Many of the weapons that were fired by the opponents collided with Yuto's fakes and those that managed to escape a similar fate wounded the two opponents although they were nothing more than superficial wounds.
"Master, how much magical energy do you have?" Mordred asked seriously.
"Not much," Yuto admitted. "Morgan told him about Unlimited Blade Works. He was prepared."
Mordred grimaced disappointed. Reality Marble was the opposite weapon of the Gate of Babylon and therefore the winning weapon of the Holy Grail War. "That bitch thought of everything." Mordred took a breath and focused her attention on Gilgamesh. "Never mind. We'll finish it the old-fashioned way and claim the final prize."
"Then I will use her sword," Yuto smiled; he put a hand on his chest that began to shine. A golden and blue sheath with a sword in it came out of his body. "On my count. One."
Mordred grinned.
"Two."
Yuto drew Excalibur out of the sheath.
"Three!"
Yuto and Mordred run towards Gilgamesh. The King of Heroes smiled arrogantly.
The last battle of the Sixth Holy Grail War had been going on for over an hour. Mordred's armour was partially destroyed, and Yuto had healing wounds thanks to the sheath implanted by his father. Gilgamesh was the best among them since he had only one small problem.
"Set!" Yuto threw four Black Keys into the air and then stopped in the middle of four magic circles. With a simple gesture of Yuto's hand, the swords used by the church were fired at Gilgamesh, who was not intimidated.
"Useless," the King of Heroes laughed at them as he opened four doors from which he fired four swords, which Yuto scanned to find out his identity. Each had sufficient power to wipe them out, yet Yuto and Mordred would not give Gilgamesh the pleasure of seeing them back. Rather, they would challenge them face-to-face.
Since they were four legendary weapons, the Black Keys produced through Yuto's Magecraft broke as if they were made of glass, not that Yuto hoped to win with mediocre swords like those. The four weapons flew against Yuto who threw himself to the left to avoid them.
"That woman was wrong about you in the end. What a miserable end for the King of Knights and that miserable faker," Gilgamesh mocked with an arrogant smile on his face.
He observed them. They were his final obstacle he could lay his hands on the Holy Grail and make him pour All the World Evil upon mankind, killing the people and ruling like a Tyrant over those who had managed to survive.
Gilgamesh opened several doors, but the grin vanished from his face as he saw them closing before his eyes. Turning to Yuto and Mordred, they were laughing in his face as Yuto had forcibly closed his doors through the catalyst used by Morgan to summon him ten years earlier: a discarded key to his vault.
They stood before him with the irreverence of those who didn't care about having a king in front of them. He could simply be a king or a soldier, he was an enemy to defeat and given the situation, it was already so long that Yuto had waited so long just to please Mordred.
"I see. That was the plan," Gilgamesh grunted irritated as he watched the two siblings, "I should have killed you when I had the chance ten years ago."
And this mistake would have been his condemnation. Ten years had made Yuto a person accustomed to seeing blood and even killing.
Gilgamesh had been a powerful and threatening opponent, supported by a master who was a snake constantly weaving poison.
Yuto quickly thought back on what had happened so far, on all the mistakes and wrongs he made and suffered. Even though he had given up revenge, he felt satisfied to ruin the plans of two idiots.
It was a half-victory that was still satisfying.
"Hey, sis, what do you think if I reinforce you with a command spell?" Yuto asked.
Mordred smiled when she realized that it was time to end the fight and the Sixth Holy Grail War. "You are my master, and I am your servant! Do whatever you think is right to do to destroy this bastard's delusions of grandeur!" she answered with a smirk smug.
Another seal disappeared and Saber's magical energy increased greatly.
The blade assumed a blood-red colour like the surrounding area. The Noble Phantasm of Mordred was an application of her hatred of the King of Knights in the form of magical energy.
"Clarent..."
She lifted her sword over her head, causing the area to assume a blood-red colour.
"Blood..."
She swung her sword down, releasing a scarlet lightning that destroyed everything in its path. Although that was all her grudge, that attack was a hymn praising Arthur for simply giving birth to someone who accepted her for who she is.
"Arthur."
Upon her release, Mordred was forced to stab her sword into the ground and use it to keep her standing, while she breathed anxiously and had no magic power left.
It spent a few moments until the mouths of Yuto and Mordred opened wide in horror when they saw the scene before their eyes. Gilgamesh was still standing though he was severely wounded. They were exhausted and had no other cards to play.
"No way! He is immortal," Mordred said surprised as she struggled to stand up.
"It's not... over..." Gilgamesh said, gasping. The man was still standing even though he was seriously injured.
"Yes, it is," Yuto promptly replied. He was armed with his father's black bow and an iron arrow was stuck in it.
"And we won," Mordred added.
The arrow was fired at a foolish speed against Gilgamesh, leaving behind a red trail, and hitting Gilgamesh's forehead in full which he could not dodge because of his injuries and fatigue.
Mordred pushed Clarent inside Gilgamesh's chest.
"Damn... Faker" Gilgamesh murmured.
Yuto fell to the ground exhausted as he let his father's bow vanish. Mordred sat down next to him and hit her younger brother's shoulder.
Yuto noticed that his sister's face had suddenly become gloomy.
"Is there something wrong, Mordred?" he asked.
"What a shitty ending. I will return to the Throne of Heroes and I will forgot everything. This depresses me . If only the Grail wasn't corrupted..." Mordred turned to Yuto. "Now that I know it wasn't completely useless, my wish doesn't make any sense. I don't have to prove anything to anyone anymore." With a firm heart and steady hand, she handed Clarent over to her brother. "Promise me that you will live the way your father and the King of Knights would have wanted. Live to be happy and to realise your dreams. And when we meet again, whether in this life or another, show me who you have become. Make me proud, little brother."
"I will." Yuto grabbed the sword firmly. He showed her a sincere smile. "I have made mistakes that I cannot undo with the holy grail, but I will try. It won't be easy, but I'll do my best." He loaded Clarent with the remnant of his magical energy. "And I'll start by putting a stop to these sterile massacres."
"Go. Don't hesitate." Mordred encouraged.
They observed each other for a few moments before a gold cup with mystical symbols appeared where in the same spot where Gilgamesh had been until a few minutes earlier. Yuto was about to project a divine construct to destroy it, but Mordred instead made a gesture that surprised him.
"Clarent will be the pledge of my promise," Yuto said. "Clarent Blood Arthur."
Its destruction, however, caused a strong explosion and the backlash poured on Yuto who had neither the time to project any kind of defence nor to shelter somewhere. The explosion caused further damage as if a temple was set on fire and destruction wherever it was not enough.
"Thank you for everything, sis."
