Chapter 0 - Prologue

(Medieval World)

"HORAAAAA!!"

The sound of war echoed across the medieval battlefield. Thousands upon thousands of soldiers charged forward, following the commands of their kings and queens—driven by greed, hunger for power, and the desire to conquer the world.

KABOOM!!

But among all those people… there was someone different.

A lone medieval soldier barely survived the onslaught, stumbling forward toward the undead army. Thousands had already fallen in the blink of an eye. At the top of a cliff, through the dust and fog of battle, something—or someone—stood. 

His glowing blue eyes pierced through the haze. He wore strange clothing and armor, and his left arm had transformed into a massive cannon.

Suddenly, the soldier screamed:
Medieval Soldier: "W-What kind of monster are you…?!"

He pause and Grip dirt underground stare at person hatered who standing the cliff.

"A non-human like you… your race, your appearance… THAT YOU SHOULDN'T BEEN HERE FROM THIS WORLD!!!!"

(Present Day)

A day of world war Modern, Leo Ashford was a specialist-ranked soldier. He had years of experience, having trained in every form of military combat. He had survived countless battles.

During one mission, the enemy’s airship was about to escape. But Leo wouldn’t let that happen. Alongside his lieutenant, he approached the side of the hovering enemy ship. Leo climbed aboard, ready to plant a C4 on its malfunctioning system—until disaster struck.

Leo Ashford: "Ughk!? My arm is stuck! Lieutenant, help me!"

Lieutenant: "Hang in there, kid!"

They struggled to free Leo’s arm, but the automatic doors clamped down tight. The airship began to rise.

Leo Ashford: "They're about to leave... Lieutenant, listen to me. You have to Let me go."

Lieutenant: "What? What are you saying?"

Leo Ashford: "I’m sorry, sir. I have no choice  to sacrifice myself..."

Lieutenant: "Shut your mouth, Specialist! There has to be another way!"

Leo smiled faintly at his commanding officer and spoke his final words.

Leo Ashford: "It’s okay, sir. There’s no other choice. I have no regrets..."

With those words, Leo kicked the lieutenant off the airship—accepting his fate.

Lieutenant: "LEO NO-"

KABOOOM!!

The enemy ship was destroyed. The war was won. But Leo Ashford..

the hero was gone.

(At funeral)

Seven day at his grave, soldiers gathered to honor his sacrifice. The lieutenant, unable to forget his comrade, placed a hand on the tombstone, mourning him as if he were his own son.

Then, a mysterious man in a sharp suit approached. A pin gleamed on his chest

he was Director Kris La Doven. He handed a card to the lieutenant.

The card read: "Fort Vanguard" — the most advanced military organization, known for creating humanoid weapons.

That day, the lieutenant learned: Leo Ashford would be rebornnot as a man, 

but as a weapon.

10 years later...Inside Fort Vanguard Headquarters, Leo’s new body lay on an operating table. He looked younger than before. His chest was open, his mechanical systems still under construction. Robotic arms worked around him.

His second life… has now begin.
