Kumagawa was reborn into the world of Toaru as an esper with an ability he calls, Gods Paintbrush. His name was Kumagawa but he certified did not have any relations to the Antagonist of Medaka Box.
He was weak esper that usually earned miney from creating small time mangas and his esper abilities name was just him overexaggerating his potential.
Today was the second day he had released a manga from his original world — Fullmetal Alchemist.
Not the whole thing. Just the first chapter. Twelve pages, hand-drawn with mechanical precision, every panel composed the way Hiromu Arakawa had composed it across a life Kumagawa no longer lived. He'd uploaded it to AcaCity's amateur manga platform, ArcPost, under the username [GodsPaintbrush], priced at zero yen because charging for stolen work felt like a step too far even for him.
The comments had been... something.
[AutoAnon_771]: the linework on the flame alchemy sequence is insane. what pen settings.
[GodsPaintbrush]: natural hand. no tablet.
[AutoAnon_771]: liar
[NullReader]: the way the perspective breaks in panel 7 looks intentional but i cant figure out what its doing
[GodsPaintbrush]: its doing exactly what you think its doing. youre just not committing to the thought.
[ThermoGirl_heat]: chapter 2 when
[GodsPaintbrush]: soon.
He closed the browser tab.
His room in the Level 1 dormitory block was small — not offensively small, just small in the way that reminded you daily that the city did not think you were important. A single desk. A single window that looked out at a single wall. The bed was pushed against the corner to give him floor space, and the floor space was used entirely for stacked paper.
Stacked paper was, generously, what he called his workspace.
More accurately: it was a graveyard of completed pages. Chapters from series he remembered perfectly, rendered in a handwriting style that technically belonged to nobody in this world. Storyboards. Reference sketches. Character sheets for protagonists who didn't exist here yet.
He had a good memory. Better than good. He remembered everything from his previous life with the crisp, cruel clarity of someone who had apparently been reincarnated specifically to be haunted by it.
His esper ability — Gods Paintbrush, Level 1— was the actual source of his craft. Not dramatically. It didn't conjure images from the aether or channel divine inspiration. What it did, technically, was grant him micro-scale motor calibration. His hands did not shake.
His lines did not waver. Every stroke landed exactly where he intended it, with exactly the pressure he intended, at exactly the speed required.
That was it.
The researchers at the Bank had logged it, tested it, assigned it a level, and moved on. Precision motor output beyond standard human capability. Useful for surgery, assembly, forgery. One researcher had noted in the margins: esper claims ability name reflects untapped metaphysical potential. Disregarded.
Kumagawa had smiled reading that. He'd been disregarded his whole first life too.
The ability was genuinely modest. He couldn't fight with it. He couldn't cheat tests with it. In the broader ecosystem of Academy City, where children were developing telekinesis and electromagnetism and future-reading and gravity manipulation, a boy who could draw very straight lines barely registered.
What it could do — what he could do, as a passenger carrying seventeen years of someone else's manga history — was produce work that this world had never seen.
He picked up his pen.
Chapter two of FMA. The Elric brothers arrive in Lior. Twenty-two pages. Father Cornello scene.
He knew every panel. He'd read it enough times in his old life that it lived behind his eyes like a film he could pause and rewind. All he had to do was copy it out — trace it, essentially, from the projection in his memory — with hands that never failed him.
It took him four hours.
When he was done, he scanned the pages with the battered device on his desk and uploaded them to ArcPost.
Then he stared at the ceiling.
Is this plagiarism if the original author doesn't exist in this dimension?
He thought about it genuinely for a moment.
...Probably still plagiarism. Different dimension, same crime.
He didn't particularly care. He cared about two things: eating regularly, and the small, private thrill of watching people in this city — this place full of extraordinary powers and scientific arrogance — encounter something extraordinary made entirely by hand. No ability beyond steady fingers. No formula. No calculation.
Just lines.
His phone buzzed.
A notification from ArcPost. Not a comment this time.
[Private Message — ThermoGirl_heat]:
hey. the linework in ch2 panel 14. the background crowd. how many people did you draw back there
He counted mentally. Forty-three.
[GodsPaintbrush]: forty-three
[ThermoGirl_heat]: WHY
[GodsPaintbrush]: because they were there.
[ThermoGirl_heat]: youre insane. i want to meet you.
He set the phone face-down on the desk.
Academy City, he thought, is going to be a problem.
He was right, as it turned out. But that was a problem for later.
For now, he picked up his pen.
Chapter three was the one where things started going wrong for the Elric brothers, which felt appropriate.
Things were always going wrong for somebody.
For his next manga, he may just make Mob Psycho 100
Unknown to him though, a few people—especially the magic side found his view on this type of Alchemy interesting and they though. Why not try to do what those two brothers did just for the fun of it.
In an abandoned building, a rogue magician who was bored out of his mind.
The circle took him three hours to draw.
Valthor Reiss — freelance magician, thirty-one years old, wanted in two countries for reasons he preferred not to discuss — had copied it from the manga with what he considered admirable dedication. Panel fourteen of chapter two, the one where Cornello's crowd-control transmutation circle was briefly visible in the background. Small. Partially obscured. The kind of detail most readers skimmed past.
Valthor did not skim.
He had a magnifying glass, tracing paper, a ruler, and seven years of formal magical training that told him — with escalating alarm — that this circle was wrong in ways that were also somehow right.
"It doesn't correspond to any known system," he said, to nobody. He'd been narrating his work aloud since his partner had left him, and he hadn't bothered to stop. "The outer ring is almost Enochian but the segments are wrong. The inner geometry is — it's doing something with equivalence. Like it's trying to balance an equation."
He sat back and looked at it.
The circle was eight feet across, chalked onto the concrete floor with painstaking care. He'd filled in every symbol visible in the manga, extrapolated the ones the panel had cut off based on the symmetry of what remained, and added stabilizing glyphs from his own tradition at the cardinal points because he wasn't stupid.
"The premise," he said, "is fascinating even as fiction. Equivalent exchange. Mass for mass. Energy in, transformation out. No invocation. No deity intercession.
No spell formula in the traditional sense." He paused. "It's alchemical in the medieval sense but the circle is doing something the medieval alchemists never figured out."
He looked at the iron ingots he'd placed in the center.
Two kilos of scrap iron. Arranged loosely, the way the manga had arranged them in the training scene.
His intention: test whether the circle did anything at all. His expectation: nothing. His hope, which he would deny if asked: something small. Something interesting
.
"Worst case," he told the room, "I've spent an evening drawing on a floor. Which is — fine. I've had worse evenings."
He placed both hands on the outer ring.
In magical terms, this was an absurd gesture. Circles in his tradition required voiced formula, prepared focus objects, a minimum of three hours of meditation beforehand. You didn't just touch a circle and expect results.
He touched the circle.
[Oh?]
Before he knew it, he was in a white space, staring at a white ball with a mouth on it.
[Human....I would have never thought that one would notice me after just being created by my creator but it is refreshing]
Valthor Reiss didn't scream. He couldn't. The air had been replaced by a silence so heavy it felt like lead in his lungs.
He was no longer in the abandoned warehouse in District 7. The grime, the smell of damp concrete, and the flickering fluorescent lights were gone. There was only white. An infinite, agonizingly bright expanse that stretched in every direction, lacking even a horizon to orient his equilibrium.
And then there was the thing in front of him.
It wasn't a god—at least, not any god Valthor had studied in the grimoires of the Magic Side. It was a silhouette, a scribble of static, a door-shaped hole in the universe that wore a grin that wasn't a grin.
"Who... what are you?" Valthor managed to croak. His voice didn't echo. The white swallowed the sound instantly.
[I am what you call the World,] the entity replied. Its voice sounded like a thousand pages turning at once. [Or perhaps the Universe. Or perhaps God. Or perhaps the Truth. I am All. I am One. And I am also... you.]
The entity gestured—or rather, the space around it shifted to imply a gesture—toward a massive, stone gate that loomed behind Valthor. It was covered in intricate carvings, a mural of human evolution and alchemical symbols that looked terrifyingly similar to the sketches [GodsPaintbrush] had posted on ArcPost three hours ago.
[Now, since you are here, what are you willing to exchange for knowledge. Your magic, your memories...or even your own body and with that exchange, you will be given a task from me.]
Valthor stared at the Gate. As a magician, he was accustomed to the "unseen," but this was not a hidden layer of reality—this was the foundation of it. The carvings on the stone doors pulsed with a rhythmic, low hum, and he recognized the central motif immediately. It was the same tree-of-life diagram that the manga protagonist had on his own Gate.
"An exchange," Valthor whispered. His mind raced. He was a Level 3 equivalent in the Magic Side's messy hierarchy—enough power to be dangerous, not enough to be a king. But here? Here, power felt like a currency he hadn't yet earned. "The boy... the one who drew this. He isn't a prophet. He's an artist. How can a story open a door to the Truth?"
The entity's grin widened, its static-filled body flickering. [Does it matter if the map is drawn by a king or a jester, as long as it leads to the destination? He remembers the Laws of a world that does not exist here. By drawing them, he gave them a voice. And you... you were the first one to listen.]
The entity leaned forward, though it had no physical weight.
[You want to know how it works, don't you? The Law of Equivalent Exchange. To obtain, something of equal value must be lost. That is the lesson the artist is teaching this city of 'Esper' miracles. But for you, the price is specific.]
"What is the task?" Valthor asked, his hands trembling.
[The artist is a 'God' who doesn't know he's holding the brush,] Truth chirped, the sound of its voice vibrating in Valthor's marrow. [He is leaking the secrets of the universe into a world that thinks it's just 'entertainment.' My task for you is simple: Be his Guardian. Protect the source of the ink. If the Alchemists of this world are to rise, the one who remembers the Truth must remain free to draw it.]
Valthor felt a cold sweat break out. "You want me to protect a manga artist?"
[In exchange,] the entity continued, ignoring the question, [I will grant you the Truth of Transmutation. No circles. No chants. Just the comprehension of the composition of matter. But... the cost.]
The white space suddenly surged. The Gate began to creak open, and a swarm of black, shadow-like hands erupted from the crack, lunging toward Valthor.
[I'll take your Eyesight, Valthor Reiss. You won't need your eyes to see the flow of energy once you've looked behind the Gate. And I'll take your Mana. You will no longer be a 'Magician.' You will be an 'Alchemist.' A being of Science and Soul, an anomaly that neither Academy City nor the Magic Side can categorize.]
"Wait—!"
The shadow hands seized him. Valthor felt a searing, white-hot agony behind his retinas. His connection to the ley lines, the familiar hum of the magic he'd spent decades mastering, was ripped away like a bandage over a raw wound. It was replaced by something else—a flood of information, a geometric blueprint of the entire universe, the atomic weight of the air, the molecular structure of the concrete back in the warehouse.
He saw the stars. He saw the cells in his own heart. He saw the very code of existence.
And then, he saw nothing.

Kumagawa rubbed some butter on toast he had just made and ate it immediately. He had to go to school early today, which was a massive bummer.
His hands drooped as he looked at the ground. "Ah, what a bummer, i wanted to draw four chapters today."
He heard a knock on his door suddenly and he groaned, he opened it and saw that Uiharu was looking at him with a curious expression.
His face was blank. "What is it Uiharu."
She blinked and then seemed to become flustered a bit. "Ah, Kumagawa-kun, good morning, i thought i should drop in to tell you that you are late to school since where we live isn't that far apart from one another
