I am a transmigrator.
On the surface, my current identity is nothing more than an ordinary exchange student from overseas. I've just turned eighteen. I should have followed the expected path and become a medical student—but through a twist of fate, I restarted my "life plan" in this world instead.
The stage of A Certain Magical Index and A Certain Scientific Railgun.
As a long-time otaku, Kurokami Gen was no stranger to it.
Once, he had fantasized about being transported into an anime world and building a harem. Just the idle daydream of a teenage boy. But when he truly realized what kind of world he now inhabited, he finally understood the meaning of loving dragons in theory while fearing them in reality.
The Toaru universe was a high-tier magical plane.
By the later arcs—New Testament—it had become a realm where "Magic Gods walk the streets, and angels are worth less than dogs." If an ordinary person were dragged into one of those apocalyptic incidents, survival would be impossible.
At the same time, those aloof Magic Gods could perceive the presence of a transmigrator almost instantly, using them as entertainment in their omnipotent, unbearably boring lives.
Transmigration inevitably disturbed the "phase" of the world. And magic itself was intrinsically tied to those phases.
Could it be that my [Heal] belongs to an entirely different magical system?
Gen stared at his own hands.
When he crossed over, the only thing he carried with him was the starter skill set from Redo of Healer. Everything else still required development.
Activation of [Heal] required physical contact for up to five seconds. Even the consumption of magical energy would itself be "healed." Aside from the dual backlash on mind and body, there was no mana cost, no cooldown.
Was this really magic?
If it could copy esper abilities, then in theory, even the indigenous magic system of this plane wouldn't be out of reach. Yet its true power went far beyond simple replication.
One month had passed.
And I'm still alive.
The Magic Gods hadn't come knocking. For now, I had escaped disaster.
Perhaps they were too busy gazing at the stars to bother observing Earth.
Even so, danger lurked everywhere.
Kurokami Gen understood clearly just how much darkness lay hidden within this city.
At this very moment, at least fifty million nanomachines—the AIM Stalker surveillance network—floated invisibly through the air. The Board Chairman, Aleister Crowley, monitored every corner of Academy City through them.
That man stood at the absolute ceiling of power in this world. Even the original protagonist had been nothing more than a chess piece in his hands.
To avoid being dissected as a lab specimen, Gen had never publicly revealed his true ability—[Imitation (Heal)].
Of course, nothing escaped the gaze of the man hanging upside down.
It seemed Aleister had no intention of contacting him yet. Observing from the shadows, perhaps? That was his style—allow events to unfold naturally, then quietly manipulate them into becoming part of his grand design.
As long as I don't interfere with his core plan, my life shouldn't be in immediate danger.
Gen steadied himself.
Only one secret absolutely could not be exposed: transmigration itself. The Magic Gods would never ignore such an amusing "otherworld." In his current fragile state, he couldn't even withstand ordinary esper powers.
So I rewrote my own memories using Lv.2 [Mind Hound].
Who would have thought it would truly come in handy?
"This city is full of people abusing their powers just because they can. Is everything forgiven simply because they're students?"
Gen's left eye glowed with a crimson bird—the Geass of Code Geass.
[Mental Out] was an umbrella category encompassing all forms of psychological manipulation. Its outward manifestation depended on its user. In Misaki Shokuhou's case, it appeared as starry pupils.
Based on Gen's understanding, he instinctively associated mind control with Geass. Unlike Shokuhou, he had no research institution designing specialized remotes to finely tune and suppress the ability, preventing it from running rampant.
Then I'll just control it in a way I understand.
"In the name of Lelouch vi Britannia… I am your wallbreaker."
…No.
I'm past my chuuni phase.
Let's just treat it as stylish cosplay contacts. Convenient, really.
Gen touched the corner of his eye. His right eye shimmered emerald.
For some reason, he had carried these eyes over as well. Perhaps he had been watching that particular episode while bingeing anime before transmigrating? The omniscient eyes granted through a contract with spirits in Redo of Healer—eyes that perceived the myriad phenomena of the world.
His own status information unfolded before him.
True Name: Kurokami GenRace: HumanClass: Healing Hero, Pseudo-EsperAge: 18
Combat Skills:
[Emerald Eyes]: Eyes of omniscience obtained through a contract with the spirits of the world. Can perceive magical power floating in the atmosphere, the flow of dragon veins, others' status values, special abilities, and true names.
[Mental Out (Lv.5)]: A composite of all mental-type abilities. Includes memory reading, brainwashing, long-distance telepathy, memory erasure, will amplification, thought reproduction, emotional transplantation, and more. A "Swiss Army knife-like" convenience ability, manifested outwardly as Geass.
…
Combined with [Imitation (Heal)], the insight of [Emerald Eyes] was essential. It allowed him to clearly observe the abilities he wished to copy.
As long as I remain hidden in this hospital, I can legitimately come into contact with countless espers through [Heal] every day—copying their skills silently.
A wise choice.
But there remained one flaw.
Only five copied combat skills could be retained simultaneously. Any excess would gradually fade, lasting roughly one month.
Most mental abilities would be overwritten by the superior [Mental Out], including [Mind Hound] itself.
For now, mastering this was sufficient. Most other abilities weren't useful anyway. The passive forgetting issue could be addressed later.
After "breaking the wall"—unlocking his sealed memories of transmigration and plot—Gen finally understood the truth of his powers. He deactivated Geass and Emerald Eyes. When he put his glasses back on, he looked scholarly, harmless. Slightly more mature.
"Ah—!"
A woman's scream pierced the air.
Gen's eyes sharpened instantly as he rushed to the hospital lobby.
A student-aged thug was holding a young nurse hostage, retreating toward a wall.
"Don't come any closer, or I'll kill her!"
So today, Academy City is "safe" as always.
"Calm down. Violence won't solve anything. I'm a doctor here. Whatever you want, we can discuss it."
Medical staff froze. Onlookers gathered despite their fear. The second floor was soon packed.
Gen knew this hospital had top-tier security. Anti-Skill would arrive shortly.
Even if someone were injured, he could just [Heal] them afterward.
But…
He stopped retreating.
That nurse had greeted him sweetly earlier.
Gen stepped forward.
The thug snarled, "After I had a brain tumor removed here, my ability development stalled! I'm going to make that frog-faced surgeon never hold a scalpel again!"
Ah.
So that's it.
The surgery had been flawless. No malpractice.
In truth, every student's developmental limit was predetermined. The man he sought revenge against was someone even the Chairman wouldn't casually offend.
While speaking, Gen activated [Emerald Eyes] discreetly behind reflective lenses.
True Name: Miyagi RyosukeRace: HumanOccupation: Level 3 Esper (Temporary Boost)Age: 17
Combat Skills:
[Ray Deflection (Lv.3)]: Can visually perceive radiation and deflect alpha, beta, gamma, X-rays, and neutron radiation.
[Level Upper]: Network node; temporary enhancement via brainwave connection.
…
The rest were mundane "skills."
So he'd smuggled the knife through security by bending radiation scans.
Pathetic.
But more importantly—
Level Upper had appeared.
Gen's thoughts flashed. In reality, only seconds passed.
"I'm that surgeon's student. He hasn't performed surgery yet. If you want a hostage, trade her for me."
Gasps erupted.
"Nang—Kurokami-kun…"
The nurse trembled with tears in her eyes.
Miyagi hesitated, then shoved her aside and seized Gen instead.
"Don't move! I'll slit your throat!"
The blade cut deep.
Blood poured.
Screams.
In that split second of distraction—
Gen moved.
He twisted the thug's wrist, ducked low—not to escape, but to torque the arm violently.
Then—
He drove the knife into the attacker's own abdomen.
A scream.
The thug was slammed against the wall.
The weapon clattered to the floor.
"Level 0… can do that?"
"Just basic self-defense."
Gen pinned him down calmly.
"Ordinary people can't overcome pain. That makes their weaknesses obvious."
Green light flashed across his own neck.
The wound sealed instantly.
Even Anti-Skill officers arriving moments later froze at the sight.
Yomikawa Aiho lowered her riot shield, exhaling.
"What, you already handled it?"
"Yes, Yomikawa-sensei."
She laughed. "Nice moves. Train with me sometime."
You've already taught me everything, he thought. I copied it.
The crisis ended. Miyagi Ryosuke was arrested.
Among the crowd stood Tokiwadai girls.
"Queen!"
They had rushed over only to find Misaki Shokuhou already healed.
"Did you figure him out?" she asked softly.
Mitsuari shook her head. "Doesn't seem like Dark Side. Probably learned Anti-Skill CQC from an acquaintance."
"A pain-insensitive Level 0 doctor…" Misaki murmured. "Interesting. It feels like his eyes can see right through me."
Like standing naked before him.
Back in the corridor, Gen glanced at them departing.
Good.
Even I don't "remember" transmigration or [Heal] unless I unlock it. No one can read what I myself have sealed.
I am the Wallfacer—the wall of dimensions.
The memory seal exists to prevent high-level mental espers from probing me. It unlocks only after I surpass them.
Thank you, Queen.
I've obtained [Mental Out].
Soon, I'll take [Mental Stinger], telepathy, and everything else.
Turning to the bleeding criminal, Gen smiled faintly.
"Yomikawa-sensei. Let me see him."
Miyagi ranted hatred even while wounded.
Gen leaned close.
He did not use Heal.
Instead—
Geass flared.
Through telepathy, he issued a silent command.
"Use the brain that should have been entirely removed… and end yourself somewhere unseen."
Perhaps I could simply restore him to a state before birth.
After all—
I am the Healing Hero.
