Limit Breaker: Rise of the Quirkless Hero with a System

**WARNING: THIS WORK WAS WRITTEN BY ARTIFICIAL INTELLIGENCE** In a world where 80% of the population has a Quirk, being born without one is a death sentence to your dreams. But for seventeen-year-old Renjiro Kaito, the real nightmare begins not with powerlessness… but with awakening. When he hurls himself into danger to save a stranger during a villain attack, time freezes. A glowing blue screen appears before him: [You have completed the conditions for Hidden Quest: “Defiance of the Powerless.”] [You are eligible to become a Player. Accept?] He accepts without hesitation—and dies moments later. Three days later, he wakes up in a hospital. Alive. Unburned. Unscarred. Unexplained. No one else saw the screen. No one else knows what he is now. Because Renjiro doesn’t have a Quirk. He has something far more dangerous—a system that makes him stronger through quests, dungeons, and penalties. But there's a catch. If he fails the system... it punishes him. Thrown into brutal training quests, deadly survival zones, and mysterious dungeons hidden in plain sight, Renjiro begins his evolution from the bottom. But can a quirkless nobody climb higher than even the mightiest Pro Heroes? The world doesn't know him yet. But soon… they'll fear the name “Player.”
