Advanced Nurturing High School is not an ordinary institution. Built by the Japanese government to cultivate the nation's future leaders, it is a closed ecosystem where students are ranked, monitored, manipulated, and quietly pushed to their limits. Status is currency. Intelligence is weaponized. Trust is fragile. Every class is a battlefield fought with strategy instead of fists. In this school, monsters are not born from darkness, but from ambition. But what happens when a real monster walks through its gates? He was a third-generation product of the White Room, engineered to surpass human limitation, stripped of warmth, empathy, and identity before he could even understand those words. Unlike the others, he did not merely adapt. He excelled. Not just because of conditioning, but because he had been born different. His body was superhuman from the start, with strength beyond that of trained adults, reflexes bordering on precognition, and endurance that ignored pain. The instructors called him a demon of the third generation. Eventually, he escaped. Instead of becoming the weapon they designed, he was found and saved by the world's greatest vigilant hero, Ben Tennyson. Where others saw a threat, Ben saw a child. He gave him a home, a name, and something the White Room never allowed, choice. Under his guidance, the boy learned restraint. Learned humor. Learned that power exists to protect. Eventually, he inherited the Omnitrix, the most powerful device in the universe. A watch capable of transforming its wielder into alien beings of catastrophic strength. He fought in shadows. Saved worlds. And after his father sacrificed himself to safeguard existence, he carried that burden alone. Now, by fate's irony, he attends Advanced Nurturing High School. They created a demon in the White Room. A hero raised him. A weapon chose him. His name is Izuku Tennyson, and this is the story of how he survived three years in a normal high school while being a vigilante.

Izuku Midoriya was never meant to exist in Remnant. One moment, he was fighting in a world ruled by Quirks and heroes. The next, he wakes beneath a shattered sky, surrounded by Grimm, Dust, and a world that knows nothing of mercy. And then the System activates. Levels. Stats. Skills. Titles. Power that grows with every battle and every choice. No mentors. No safety net. Just cold numbers, hard-earned strength, and a world that will either bend... or break. Beacon Academy calls him a Huntsman-in-training. The Grimms see him as prey. In the shadows, Salem observes the anomaly carefully. He's calm. Calculated. Dangerous when pushed. A man who grows stronger with every fight, every kill, every secret revealed. As Team RWBY and JNPR cross paths with this strange, disciplined warrior, they begin to realize something unsettling: Izuku isn't just adapting to Remnant. He's ascending. Power attracts attention. Attention brings enemies. And some forces in Remnant were never meant to be challenged. This is the story of a world colliding with a System it was never designed to handle-and the quiet, relentless rise of the one man standing at its center. System. RWBY. Power progression. Slow burn. No mercy. Timeline: After Volume 1 events: Black and White

In a world where quirks define destiny, Izuku Midoriya was already defying expectations by inheriting the legendary power of One For All. But after the USJ incident, strange memories and unfamiliar instincts begin to surface-echoes of another life, another power. When a forgotten notebook resurfaces in his home, Izuku uncovers a truth buried beneath his very bloodline: he is not just a hero-in-training. He is the last surviving Saiyan. As Izuku trains for the U.A. Sports Festival, he quietly begins walking a dual path-mastering One For All while unlocking the ancient energy known as Ki. With each day, he draws closer to the legacy left behind by his mysterious father, a Saiyan exile named Goza who sought peace in a world that feared power. But with new strength comes new questions. Can Izuku balance the fire of his Saiyan heritage with the heart of a hero? And when the echoes of the past grow louder... will the world be ready for what he becomes?
