Chapter 1: This Was Not What I Chose
There was a moment, before the water, before the cold, before everything stopped making sense, when I was still myself.
I don't know how long it lasted. A second. Maybe less. Long enough for one last fragment of something to pass through where my head used to be: the screen of my monitor. Code half-compiled. A bug on line 2,847 I'd been trying to fix for three hours. The cursor blinking. The cold coffee to the left of the keyboard. The sound of the office air conditioner, that constant hum I'd stopped hearing years ago and which now, here, wherever here was, was the last thing I had left.
I tried to hold on to it. To the screen, the cursor, the hum. Like when you close an application and for a fraction of a second you can still see the image before the memory releases it. But the memory was releasing. The coffee went first. Then the hum. Then the screen. Then the sensation of having fingers to type code with, the sensation of sitting in a chair, the sensation of weighing sixty-eight kilos on a planet rotating at the correct speed.
The last thing to go was the bug on line 2,847. I never fixed it. That should have bothered me more than it did.
Then, nothing. And after the nothing, water.
The first thing I perceived was water. Warm, dense, tasting of dirt and something vaguely metallic I couldn't identify. The second thing was that I had no hands. That was inconvenient. The third thing was that I had no legs, no torso, no neck, nothing that could remotely be considered a human body.
I had mass. A tiny mass with something resembling a tail.
The sensations arrived in disorder, like data from a corrupted file that a brain was trying to parse with the wrong tools. Water pressure. Texture of mud under something that wasn't feet. Temperature fluctuations that my body registered with a precision no human sense had ever possessed. And above all, an absence: the absence of arms, of legs, of fingers — of everything that had always been the interface between my mind and the world.
I tried to move. My body responded with the grace and coordination of a wet paperclip on a frictionless surface. I traveled three millimeters to the left. Or to the right. Or upward. It was hard to tell without a clear reference frame, and without eyes that could focus beyond a few centimeters.
Okay. Debugging. Last known state: floating screen, white void. Reincarnation options. Golden letters. "Primordial Dragon of Eternal Flames" with a description so excessive it read like French perfume marketing copy. System confirmation. A flash of light.
And now I'm in a puddle.
Measuring, if I'm being generous with myself, three centimeters.
There's a bug somewhere in this process. A fairly significant one.
I tried to pull up the status screen. In isekai novels it always works. You think hard enough about seeing your stats and a floating window appears. I tried. Nothing. I tried harder, the way you press an elevator button repeatedly because you believe it will arrive faster. That didn't work either. So I thought, with all the clarity I could manage: "Status."
And there it was.
[Species: Primordial Dragon of Eternal Flames
Evolutionary Stage: Pre-Egg
Sub-stage: Aquatic Larva (Phase 1 of 3)
Evolutions Complete: 0 / 47
Current Form: Igneous Tadpole (Level 1)
Unique Skill Unlocked: Spark — inflicts 0.5 the
mal damage on contact]
I read each line. Read it again. Read it a third time, in case the text changed between readings the way store signs say "open" when they are clearly closed.
It didn't change.
Primordial Dragon of Eternal Flames. That part was correct. I had chosen that. I remembered it with the clarity of someone who has just made a mistake they will regret for the rest of their life. Which in my case might be very short.
Evolutionary Stage: Pre-Egg. Pre-Egg. I wasn't even an egg. I was the thing that comes before the egg. If the egg was the first step, I hadn't even reached the starting line. I was in the parking lot of the starting line. Trying to remember where I left the car.
Evolutions complete: zero of forty-seven.
Forty. Seven.
In the novels, when someone reincarnates as a dragon, they generally wake up already being a dragon. Maybe a young dragon. Maybe an injured dragon. But a dragon. With wings, claws, fire, and a gold-filled cave in which to philosophically contemplate the mortality of humans. I had a tail, half a point of thermal damage, and a puddle that smelled like rust.
Then, because the universe apparently wasn't finished with me, another notification appeared.
[Welcome to Ignarion. Your reincarnation has been
processed successfully.]
Successfully. The word "successfully" doing a lot of heavy lifting in that sentence.
[System Tip: Primordial Dragons of Eternal Flames have the longest evolutionary cycle of any registered species. Patience is recommended. Note: Survival rate in the Pre-Egg stage is 0.3%.]
Zero point three percent. Which is another way of saying ninety-nine point seven percent die.
Patience is recommended. Patience. The quality you need when you're waiting in line at the bank, not when ninety-nine point seven percent of those in your situation don't survive. For that you'd recommend something else. Panic, for example. Functional terror. A miracle.
I closed the status screen. Opened it again. It still said the same thing. Closed it again. Looked at the puddle. Looked at my tail. Looked at the blurry nothing that were my tadpole eyes trying to process a world designed for creatures with functional retinas.
Fine. Okay. This is fine.
It was not fine. None of this was remotely fine. But experience had taught me that the first step to solving a problem is to pretend you're not panicking while you panic.
* * *
My name was Kaito Mori. Twenty-eight years old. Programmer. Backend development department at a software company in Tokyo whose name no longer matters. I died in the most anticlimactic way possible: I choked on a tuna onigiri at lunch while reading an isekai manga on my phone.
The irony is not lost on me. It wasn't lost on me while I was choking in the third-floor break room and it isn't lost on me now, three centimeters of tadpole floating in warm water in a world that isn't mine.
The last thing I saw before everything went dark was my phone screen showing a chapter where the protagonist reincarnated as an all-powerful dragon and destroyed an army on the first page. The first thing I saw afterward was the divine selection screen offering me exactly that. The universe has a sense of humor I don't appreciate nearly enough.
The selection screen. I remembered it with an irritating clarity. A white void extending in every direction. A voice that wasn't quite a voice, more like an understanding that appeared directly in the mind, explaining the rules. I had died. I had been selected. I could reincarnate into a world called Ignarion. I was required to choose my form.
Five options. Each with a description that read like it was written by the marketing department of a gacha game with an unlimited budget.
A phoenix with 23 stages that resurrected on death. A behemoth with 15 stages, indestructible and slow. A kraken. A hydra. And at the end of the list, in letters slightly more golden than the rest…
[Option 5: Primordial Dragon of Eternal Flames — Evolutionary Cycle: 47 stages
"The most powerful creature in Ignarion. Lord of fire, sovereign of the skies, living legend."]
Forty-seven stages. Right there. In the description. The number. I saw it. I read it. And my brain, applying the same ironclad logic that made me order the largest combo at restaurants because "if I'm spending money, it might as well count," decided that more stages meant more power. That forty-seven was better than twenty-three because forty-seven was a bigger number. That "the most powerful creature" was the obvious choice.
At no point did I process that forty-seven stages meant starting forty-seven steps behind. That the phoenix with its twenty-three stages probably started as a chick, not a tadpole. That the behemoth, at fifteen, almost certainly woke up as something that could at least step on things.
There was also a footnote. Small. Nearly invisible. It said: "Evolutionary cycle: extended. See conditions." I didn't read it. Who reads the conditions? Nobody reads the conditions. We accept the terms of service for every application without blinking and now I'm paying those consequences in a puddle.
I chose option five. The System confirmed my choice with a golden flash and a message about an "initialization process." It felt like applause. In retrospect, it was probably laughter.
And now I'm here. Three centimeters. A puddle. Forty-seven evolutions between what I am and what I was supposed to be.
Noted.

The puddle was larger than it looked. Or I was smaller than I'd thought. Probably both.
I spent what felt like an hour exploring my immediate surroundings. My sense of time was imprecise, my sense of distance worse, but I was building a mental map through movement and repetition.
The puddle was oval-shaped, fed by a thin stream that entered at one end and exited at the other. The water was murky, full of decomposing organic matter, rotting leaves, and particles floating like dust in a poorly ventilated room. But it was warm — warmer than a normal puddle should be — and there was a zone near the center where the temperature climbed a few degrees more. Something beneath the ground was heating the water from below. A geothermal vein, probably. My Igneous Tadpole body gravitated toward that warmth instinctively, without any conscious decision on my part.
There were other tadpoles. Normal ones. Of some local amphibian species I didn't know and didn't care to know. They were bigger than me. Not by much. But enough that my pride, already beaten to something approaching a liquid state, absorbed another dent. They were completely ordinary tadpoles — no skills, no status screen, no draconic destiny — and they had me beat on size. If this were a company, I'd be the new hire who shows up with an impressive title only to discover he can't even afford his own cubicle chair.
I couldn't see well. My vision was a blurry smear where shapes were distinguishable more by movement and contrast than by any actual detail. I could tell the difference between light and darkness. I could detect something moving fast near me. But the visual resolution was that of a photograph taken underwater by someone sneezing during an earthquake.
What I could feel was temperature. That I felt with a clarity no other sense came close to matching. The warm water of the puddle. The colder current of the stream. The hot zone over the geothermal vein. Each degree of difference was sharp, like colors to someone who can only see in a heat scale. It was my dominant sense. My window onto the world. And that window showed more than my eyes ever could.
Because through temperature I could perceive the ecosystem. Every living creature emitted heat. The normal tadpoles were warm dots moving in erratic patterns. There was something larger at the bottom of the puddle, buried in the mud, radiating a slow steady heat like a draining battery — probably some type of worm or large insect larva. And at the surface, where water met air, signatures appeared and vanished: insects landing on the puddle, feeding on something, and departing. A constant traffic of tiny organisms living complete lives in the distance between two floating leaves.
It was an ecosystem. Small, dirty, irrelevant to any creature above level three. But a complete ecosystem, with its food chains and its hierarchies. And I was at the absolute bottom of every single one.
I tried my one ability. Spark. Half a point of thermal damage on contact. I activated it with intention, the same way I'd summoned the status screen.
I felt a tiny pulse leave my body like an exhaled breath of heat. It lasted less than a second. The water around me warmed a fraction, in a radius of about ten centimeters. That was it. That was all I could do. My great draconic power. My inheritance of the Eternal Flames. A tepid shiver that wouldn't have warmed a cup of coffee.
I tested the limits. Spark cost half a point of Energy. I had seven points total. I could use it fourteen times before hitting zero. After that, nothing. A particularly small tadpole at the mercy of an ecosystem that had no reason whatsoever to keep it alive.
A tadpole with the most impressive title in the catalog and the combat capability of a wet lighter.
Noted and filed.

The bird arrived when the sunlight fell vertically over the puddle.
The normal tadpoles sank toward the bottom, burying themselves among the rotting leaves in the mud with an instinct I didn't have. Something in their biology screamed that direct light meant open sky, and open sky meant predators. My Instinct, with its heroic three points, told me nothing. I stayed where I was, near the warm zone, checking my status screen for the fifteenth time like a passenger watching the departures board and waiting for his cancelled flight to magically reappear.
The shadow crossed the puddle like a blur.
I didn't see it coming. I only felt the water displacement — violent, sudden — and three normal tadpoles that had been within half a meter of me vanished. They didn't move. They didn't flee. There was no struggle. They were there and then they weren't. Like variables deleted from a running program.
A bird. Large. Large enough that its silhouette blocked the sun from my puddle-bottom perspective. It perched on a branch above the water, motionless, with the patience of something that has no hurry because it doesn't need any. It waited. It calculated. It descended again.
The water exploded to my left. Another impact. Two more tadpoles vanished in a fraction of a second. The turbulence swept me sideways and I collided with a submerged root. The bird rose, perched, waited.
And then I noticed something that chilled whatever tadpoles have instead of blood: I was lit up. Spark, which I'd left active without thinking, was heating the water around me. The temperature differential was creating a visible distortion at the surface — a kind of thermal shimmer broadcasting my position like a neon sign on a dark street. I was, quite literally, advertising myself.
The bird tilted its head. I felt it more than saw it. The calculating movement of a predator evaluating whether whatever it sees below is worth the effort.
I deactivated Spark. I moved. Clumsy, desperate, pure reflex. My tail thrashed with the efficiency of a broken oar and I displaced myself downward, into the mud, into the dark. The shadow fell. The beak struck the water where I'd been half a second before. The shockwave pushed me against the bottom. Particles of mud and leaves obscured everything.
When the turbulence settled and the water recovered some clarity, another tadpole was gone. Six total. There had been roughly twenty to start. Now fourteen. And the bird was still up there, its patience intact, waiting for the puddle to calm before descending again.
I stayed at the bottom, half-buried in mud, motionless, with something I didn't know was a heart beating at a speed that couldn't be healthy for a three-centimeter organism. I didn't move. I didn't use Spark. I didn't breathe any harder than necessary.
The bird descended twice more before it left. It took three tadpoles on the first dive, two on the second. When its shadow disappeared, there were nine of us. Nine of twenty. In one afternoon.
Zero point three percent survival rate.
I was starting to understand how they arrived at that number.
* * *
I spent the rest of the afternoon doing two things: hiding and thinking.
Hiding was the easy part. The mud at the puddle's bottom was soft and deep. I buried myself until only the tip of my tail was sticking out, like a tiny worm with delusions of grandeur. It wasn't dignified. It wasn't epic. It was effective. At the current scale of priorities, "effective" beat "dignified" by a margin I wasn't willing to calculate.
Thinking was the complicated part. But thinking was what I had. It was, being honest, the only thing I had.
I ran an inventory, the way you assess the state of a system before attempting to repair it.
Available resources: Spark, fourteen uses per Energy cycle, half a point of damage that wouldn't do anything to anything worth damaging. Basic aquatic mobility, slow, clumsy, no reliable directional control. Senses limited to temperature perception and blurry motion detection. And an Intelligence stat of eight points that stood out from my character sheet like a skyscraper in a town of single-story houses.
Eight Intelligence in a tadpole. It was like putting a race car engine in a tricycle. Disproportionate, yes. But it was what I had. Normal tadpoles moved on pure instinct: stimulus, reaction, nothing in between. I perceived, processed, and decided. Every action passed through a filter no other tadpole in this puddle possessed.
Threats identified: birds, predatory fish that could enter through the stream, large insects, probably frogs, snakes, and anything of level two or above. Which was, to be clear, absolutely everything in this forest except me.
