My Multisystem In Isekai

James Carter was never the strongest student at his hero academy — just the most reliable one. His ability, Bond Link, let him sense his teammates' condition and quietly sharpen their coordination from the shadows. He trusted his team completely. He protected them. He helped them grow. Then, the moment after their biggest victory, they threw him away — deemed "too dependent on others" to be worth keeping. As James walks away from the team he built, Bond Link awakens into something no one ever told him it could become. It isn't a coordination skill at all. It's the power to read — and bind — a person's true potential. And the deeper the bond, the more James can reshape someone's future entirely. At first, all he wants is answers. But when he turns his newly unlocked ability on his former teammates, he uncovers something far more disturbing: their potential has been suppressed all along — deliberately, by someone who got there before him. Someone who understood Bond Link's real nature long before James ever did. Betrayed, awakened, and now hunted by a truth buried in his own ability, James must decide what kind of power he's willing to become — before whoever created this system decides for him.

In his past life, Leonidas Vance was the Supreme Marshal of the Northern Front—a commoner who fought his way to the pinnacle of military command, only to be betrayed and executed by the corrupt Solar Emperor during the Great Demon Siege. Opening his eyes 10 years in the past, Leonidas finds himself back in his 18-year-old body: a disgraced, mana-less cadet exiled to the bleak Frostpeak Fortress. But this time, he didn't return alone. Bound to his soul is the Interstellar Sovereign Arsenal—a military system connecting him to the automated weaponry, orbital drop pods, and ballistic technology of an advanced sci-fi civilization. While arrogant noble mages rely on slow incantations and sword saints boast of bladed aura, Leonidas arms his starving garrison with armor-piercing assault rifles, anti-materiel sniper rifles, and heavy artillery. In a world where magic reigns supreme, the Reborn General is about to teach the empire that nothing breaks a spell barrier faster than a high-caliber round.

College had been nothing but hell for Wesley Quigley ever since he joined. Until one faithful night, while returning to his dorm after work, he got attacked by a wolf and thought it was the end of his life when he got bitten. However, that would turn out to be untrue as that'd only mark the beginning of his rise in college.

After his girlfriend and her secret lover took his life, Hikaru woke up in a parallel world — a nation shaped like Japan, familiar in all the ways that mattered, and dangerous in all the ways he had not yet learned to expect. Wraiths. Malevolent entities. Supernatural phenomena bleeding into everyday life without warning or apology. Armed with a Merit System and the hard-won skills of an Onmyoji, Hikaru had accepted that survival in this world would be complicated. What he had not accepted, and had not remotely planned for, was a wife. She was a Calamity of the World-Ending tier. A being so terrifying that humans and Wraiths alike trembled at the mere mention of her name. And yet. Every time Hikaru looked at her, the only word that came to mind was... So CUTE.

I was a billionaire. I was ruthless. But I died totally alone in a crushed sports car. When I opened my eyes, I was 22, sitting in my crappy college apartment, completely broke. But I wasn't alone. A glowing blue screen was floating right in front of my face. [Mythic Tycoon System Bound.] [Current Wealth: $12.00] [Warning: The corporate world is a literal jungle. Good luck.] Fate gave me a second chance to build my empire, but the System came with a hilarious catch: I have to be a "Good Boss." If I exploit my workers, my Karma Debt rises and I go bankrupt. Even crazier? I quickly discovered the modern corporate elite are secretly supernatural monsters hiding in plain sight. So, to beat them, I decided to hire my own. My new bodyguard? A 500-year-old vampire who works for minimum wage just so I'll do his taxes. My lead data analyst? A literal dragon hoarding Bitcoin in the basement server room. They have the magic. I have the brains, the System, and ten years of future knowledge. Watch me slap the faces of arrogant rich kids, hostile-takeover werewolf packs, and build the most powerful, chaotic monopoly the world has ever seen.
