Alternate Universe

"At Nexus Academy, power is determined by how far one can integrate with the System Core. Roewi Verdent? He had nothing. The System always rejected him, making him the laughingstock of the elite students. But when the academy's network collapsed, Roewi's screen lit up for the first time. A foreign voice echoed in his mind. [Vextor Protocol detected.] [Welcome, Host.] A forbidden system had chosen him. And that night, the failed student transformed into an anomaly that would shake the world."

Introvert!? Me!? The hell am I an introvert? I stay indoors all day because I am afraid of getting my butt kicked. Until I contract my beast, I won’t be walking freely. This is a promise I made to myself. My name is Ryder, and I am black-marked. The planet where I live is dominated by summoners. If you guessed it, then you are right—we contract beasts from the Astral Shadow Plain and summon them at will after successfully forming a contract. A mark appears on the left shoulder of every human after a period of maturity, a mark given by the beast that chooses you. There are five different types of marks—the brown, the orange, the red, the black, and lastly, the white. Of all the markings, I was marked black. I was chosen by a supreme demon monarch of the Astral Shadow Plain—the Dracogon. There was only a 0.5 percent chance for me to survive the contraction process. However, with a slight twist in the original outcome, contracting a creature from the black-marked plain was nothing compared to the catastrophe I caused shortly after—I opened a link between the beasts of the Astral Shadow Plain and the planet of humans, Terra. Everyone on my planet has been endangered because of me. The fact that no one knows when the link will trigger and cause a breach that pours mindless creatures into my world makes it all the more unsettling. Now, with no other choice, I have to find a way to resolve the mistake I made—alone, just like I caused it.

i took my own life expecting anime style reincarnation but little did I know the harsh truths about the gods and reincarnation process

They went to war as soldiers. They came back as brothers. But when the system they fought for betrays them, loyalty becomes their last weapon. Echo Unit was built from broken men — a reluctant captain, a rebellious sergeant, a quiet strategist, a wisecracking soul, and a young recruit with everything to prove. Together, they form one of the most lethal special operations teams in modern warfare. Deployed into a war that no longer makes sense, Echo Unit faces the brutality of combat and the corruption festering inside their own command. When a mission turns into a massacre and the truth is buried, they are marked as traitors and forced to survive behind enemy lines — abandoned, disavowed, and hunted. But in the smoke and blood of a collapsing system, brotherhood becomes their only compass. Each man must face his own demons — guilt, fear, betrayal — while holding the line for the only thing that still feels pure: each other. Years later, when the truth threatens to resurface, the surviving brothers reunite for one last mission — not for orders, not for glory, but for honor. From the trenches of betrayal to the ashes of redemption, Iron Bonds is a powerful tale of courage, sacrifice, and the unbreakable strength of men who refused to die forgotten. It’s not just a war story. It’s a story about what survives after the war.

The rain had been falling on Moonveil City since dawn, running in silver threads down the tiled roofs, spilling from gutters into the crooked alleys. The sky was low and iron-grey, heavy enough to press against the tower-tops of the Martial Regulation Bureau. Inside the courtyard of the Moonveil District Arms Hall, Kael Ruan stood in silence, a new-issued badge in his hand. He was twenty-four, too young, too brash, they’d said, yet here he was, sworn as the youngest Arms Keeper in the city’s history. His mentor, Master Renji, watched from the covered steps, eyes narrowed as if weighing more than just the rain. [Silent Oath System Activated] Oath Energy: 0/100 Core Blade Slots: Shadowsteel (Locked), Frostvein (Locked), Dawnpiercer (Locked) Techniques: Oath Cut (Locked), Sword Recall (Locked) The voice cold, ringing inside his skull had woken with his oath to defend the district. It spoke without warmth, without mercy. It offered strength in exchange for vows sworn before witnesses. But the warning was clear: break an oath, and the System would take more than power from him.

One day, Apocalypse came to pass. It started with a fog that engulfed the world. Thick and heavy in the atmosphere, nearly unbreathable to humans and able to corrupt a soul. It killed livestock, pulled buildings to the ground and deadened the soil. After a month, shields were erected over major cities to keep it out, but by then humanity could no longer see the sun. Next, they disappeared - the citizens in shieldless towns and the towns themselves - completely consumed by the fog. And in their place came monsters, beasts that craved human flesh and blood and knew nothing but destruction. In a matter of days, only half of humanity remained. . . but they didn't plan on going down without a fight.
