Long before heroes were ranked and curses were classified, the world already trembled.
Cursed energy had existed since humanity learned fear—since people named the dark and gave it meaning. In the mountains, in villages, in battlefields soaked with regret, curses were born and exorcised in silence. During Japan's Edo period, when swords still ruled and sorcerers worked from the shadows, something impossible occurred.
A child was born wrong.
Not twisted by curses, not possessed—but different.
That child bent reality without cursed energy.
What sorcerers first believed to be a divine anomaly would later be called a Quirk.
From that single birth, the world slowly changed.
Centuries later, society no longer hid its monsters or its protectors.
Heroes trained openly. Sorcerers fought in secrecy.
And yet, both stood under the same sky.
To maintain balance, the Japanese government—alongside hero associations and jujutsu authorities—created a singular institution:
The Unified Supernatural Education Authority (USEA)
A foundation with two independent but interconnected branches:
U.A. High School — training Quirk users to become professional heroes, led by Principal Nezu
Tokyo Jujutsu High — cultivating sorcerers to combat curses, following the legacy of Masamichi Yaga
Both schools retained their traditions, rules, and philosophies.
But for the first time in history, they stood on the same ground.
No student had ever crossed both paths.
Until now.
Ren Oshimiya stood quietly in the long marble hallway of USEA's central building.
He was tall for his age, shoulders relaxed but alert, black hair tied loosely behind his neck. His Japanese features were softened by years abroad—America had shaped his posture, his accent, his distance.
Yet the air here felt… familiar.
Heavy.
"This place smells like old curses," Ren thought.
"And polished hero statues."
He adjusted his bag strap as massive doors creaked open.
"Enter," a calm voice said.
The room beyond was wide and circular, walls lined with hero memorabilia on one side and ancient jujutsu relics on the other. Sitting at the center was the Headmaster of USEA, an authority above both branches—someone who answered only to the highest councils of heroes and sorcerers alike.
On the left screen appeared Principal Nezu, eyes sharp and curious.
On the right stood Masamichi Yaga, arms crossed, expression unreadable.
Three pairs of eyes examined him.
"So," Nezu began pleasantly, "you're the transfer student from America."
Ren bowed politely. "Ren Oshimiya."
Yaga's gaze lingered longer than necessary.
"You're aware," he said slowly, "that what you're requesting has never been allowed."
"Yes, sir."
The Headmaster folded his hands. "Enrollment in both U.A. High and Jujutsu High is unprecedented."
Ren met their eyes without hesitation.
"My parents were both products of this system," he said calmly. "Just… separate halves."
Silence.
The files before them told the rest.
A father—once a top graduate of U.A.
A mother—a former jujutsu sorcerer of extraordinary rank.
Both now classified as Special Grade.
Nezu smiled wider. "You come highly recommended. Almost aggressively so."
Ren scratched the back of his head. "They can be… persuasive."
Yaga snorted.
"But recommendations alone don't decide this," the Headmaster said. "Tell us, Ren Oshimiya—why do you want both?"
Ren paused.
Then spoke quietly.
"Because the world doesn't separate curses and chaos anymore."
The room grew heavier.
"Villains use fear," Ren continued. "Curses feed on it. Heroes fight symptoms. Sorcerers erase causes. If I walk only one path… I'll always arrive too late."
Nezu's ears twitched.
Yaga's expression sharpened.
The Headmaster leaned back.
"You're aware," he said, "that choosing both means being watched more closely than any student in history."
Ren smiled faintly.
"I'm used to that."
A long moment passed.
Then—
"Very well," the Headmaster said.
Nezu laughed softly. "How exciting."
Yaga closed his eyes. "Troublesome kid."
The Headmaster stood.
"Ren Oshimiya," he declared, "by unanimous decision, you are accepted as a dual-branch transfer student of the Unified Supernatural Education Authority."
The seals lit up.
The decision was final.
As Ren stepped back into the hallway, the air seemed to shift—as if the world itself had taken notice.
Unseen by anyone else, something ancient stirred.
Two systems.
Two powers.
One boy standing at their intersection.
And neither heroes nor sorcerers yet realized—
They had just admitted a variable the world had never accounted for.
