Part 1: Prologue

On a night cold as ice, the battlefield resonated with screams and roars of warriors locked in combat. Among them, two figures stood, clashing in a fiery battle. One warrior clad in blue-silver full-body armor, covering every part of his form. He wielded a heavy greatsword, matching the color of his armor. His opponent wore a long coat in shades of silver, black and light blue, with a white mask concealing his entire face. Long silver hair flowed in the wind, and a whitish glow emanated from his eyes through the mask. He held a one-handed shortsword, resembling a katana.

Their battle was epic, their movements swift as the wind and fast as light. The clash of their strength was earth-shattering, and their sword slashes rended the sky. As they fought, their gazes met, as if conversing in friendly chatter. Each move demonstrated their mastery, leaving onlookers in awe of their greatness.

As their battle reached its climax, the armored warrior first planted his sword into the ground and removed his helmet.

Revealed beneath was the face of a middle-aged man in his mid forties with a straight-lined scar over his left eye.

"My name is Xenos the Paladin. Though most know me by the monicker of the Divine Warrior," he introduced himself.

In response, the silver haired warrior removed his mask, revealing the face of a young man in his early twenties, with sharp eyes hinting at a black colour and shadowey golden glow. With a small grin on his face, he exlaimed, "Hey old man! You're quite the tough guy.''

"Well same for you," Xenos replied. "It's surprising to find young talents such as you who can match up to me. So may I ask who you are?"

"I'm but a mercenary who was paid by the army to participate in this war. I don't own a name but I am known as Spriggan," Spriggan answered.

Xenos then picked up his sword, bowed to his opponent, and took on a stance. Understanding the intentions of the swordmaster, Spriggan also took on a stance.

"Let's go all out with a final bang. What do you say old man?" Spriggan screamed.

"Agreed. I'll give it my all with this final strike," Xenos answered.

The two warriors, preparing for the final act of their battle, unleashed a surge of energy enveloping their bodies and swords. As their clash drew near, Xenos unleashed his technique, "Sword Art: Tempest Wind Blade," while Spriggan unleashed "Shadow Arcane Phase of Fire: Ameterasu ". The collision created a massive energy explosion, creating a giant crater. Amidst the falling dust, a silhouette was standing. It was Xenos, covered in blood, with a big scar on his chest and his armor cracked. Next to him, also covered in blood, lay Spriggan.

"Hey old man. I lied to you earlier. I do have a name. It's Jason. And also thank you for sparring with me. It was fun," said Spriggan with a light, satisfied smile before dying.

"You were very strong, Jason. I'll remember you. Yes. You, the warrior who managed to push me to my limits," murmured Xenos.

And so after the big battle, Xenos's side won the war after a week.

Part 2: The Beginning

The scene shifts to Earth, in modern Tokyo, where a young boy enters the bus on his way to school. Thirty minutes later, the bus derails, crashing in an accident that leaves most passengers severely injured or dead. As the critically injured young boy loses consciousness, he sees a glowing light in the darkness and then hears a voice

"Let me give you another chance at life. But know that for everything received, you must give one of equal value. Hence, one day when I require it, you shall be my proxy and my blade. Until then, enjoy this new life."

The light disappears and the young boy awakens in a grassland near a small village, reborn in another world.
