'The Kazuki Clan, in ancient times, was considered just another mediocre clan of ninjas among the clans of the Land of Fire.
But with the appearance of Kazuki Makami, the clan's third patriarch, the clan's situation changed completely.
Kazuki Makami was the first and only Kazuki to awaken what they believed to be the clan's Kekkei Genkai.
On the day of his awakening, a pair of black wings protruded from his back, with his entire body undergoing a transformation: His muscles were strengthened, his reflexes were amplified and, most impressively, an abrupt leap in the amount and control of chakra.
But what frightened the clan elders most at the time was the fact that the Patriarch was performing jutsus he had never learned before. Complex, multi-element techniques, incantations that seemed to be made of pure will, without hand seals.
The Kekkei Genkai awakened not only his body, but also his mind, making Makami more analytical, strategic, with a mind that saw beyond the ordinary.
In just a few years, his charisma and intelligence raised the name of the Kazuki clan, to the point where they were officially invited to join a village that was being formed by several other powerful clans in the land of fire, Konoha.
And even as the years passed... time didn't touch him. His body remained young, unchanged. Many whispered that he had become something other than human.
However, his fate was tragic. Too involved in village politics, Makami neglected his own power. And during the First Great Ninja War, he died under mysterious circumstances during a secret mission, leaving no heirs with the same gift.
Since then, as happened with the Kurama clan, the Kekkei Genkai of the Kazuki clan has not awakened in anyone else.
As a result, the name of the Kazuki clan was slowly relegated to irrelevance in Konoha's circles of power.
It is estimated that the Patriarch's power level rivaled that of an Elite Jōnin, but with his ability to fly, his threat level was comparable to that of Konoha's legendary White Fang, Sakumo Hatake.'
Reading this scroll about the Kazuki clan, I was surprised.
Last night I stayed up late at night re-watching some older anime I loved when I was younger and I must have fallen asleep without realizing it, but the strangest thing is that instead of waking up in my bed, as expected, I woke up in a strange room decorated in Japanese style.
Startled and confused by what was happening, before I could get out of bed to understand my situation, a huge headache came over me, with countless memories showing the complete life of a little 5-year-old boy called Kazuki Enzai.
These memories showed Kazuki Enzai's life in this place called Konoha, where everything is controlled by ninjas while ordinary people can only hope that they won't be affected by the destructive battles the ninjas wage.
This was a very frightening world to live in, both for ordinary people and for the ninjas who lived to fight and kill.
But although this world was very strange, it was very familiar to me...
'This is Naruto's world!' I thought shocked.
As a big fan of anime and webnovels, I obviously knew what tranmigration was, but if I could choose the world I would go to, Naruto would be very low on the list, since even a monstrous talent wouldn't guarantee me safety here.
But realizing that there was no way back, I tried to find my last hope... my golden finger.
'System?' I asked myself mentally, hoping it would work.
Of all the golden fingers I could get by being transmigrated, the most common, and with the greatest potential, would be a System.
Although this golden finger had its shortcomings, such as the possibility of it having sentience and becoming a pain in the ass for me, giving me missions with stupid penalties, I was still very grateful to see a red, translucent screen appear in front of me.

[Creativity Magic:A skill that transforms ideas into magical phenomena. By activating Creativity Magic, the user can create original spells, abilities, weapons or magical effects based on their imagination, converting abstract concepts into reality. The power of each creation depends on the user's clarity, knowledge and mental balance. Creations consume energy proportional to their complexity, evolve with the creator and can be modified with time and experience].
[Kankara Formula: A skill that converts magical and physical phenomena into manipulable numerical formulas. By activating the Kankara Formula, the user translates the properties of attacks, spells, forces or even natural laws into equations, allowing them to alter variables such as direction, intensity, type of energy or magical structure. Effectiveness depends on mental capacity and a full understanding of the phenomenon being analyzed. If the formula is not fully understood, the manipulation may fail or produce inaccurate effects].
Looking at this status screen, a huge smile appeared on my face.
Although it doesn't specifically say anywhere where these powers came from, among the anime I'd watched the night before was High School DxD.
Not only was the definition of [Creativity Magic] very similar to DxD magic, but the definition of my race as 'Low-Class Half Devil' made it very clear where that came from.
Not to mention the [Kankara Formula], which as far as I remember is the power of the Astaroth family in DxD, the power that served as the basis for Ajuka Astaroth to create the Evil Pieces and become the next Beelzebub.
'Maybe my surname Astaroth was part of the reason I came to this world with this golden finger set? At this point I'm not even sure if I was really a human before I came here...' I pondered confusedly.
Fortunately, considering how powerful the demons of DxD were, a sigh of relief came over my face.
The ninjas in Naruto were incredibly powerful, especially in the later stages of the anime, but compared to Sirzechs Lucifer, these ninjas didn't seem that scary.
Sirzechs Lucifer had the power to decimate an entire continent, and not just him, all the other Satans in the anime were only slightly inferior to him in strength, showing that the potential of demons is incredible.
In Naruto, on the other hand, although there were extremely powerful ninjas, very few could reach that level of destruction, and most of them had the surname 'Otsutsuki'.
Analyzing the memories I received from Kazuki Enzai, my current body, I realized that among my childhood friends there was an arrogant little white-haired boy who wore a mask to cover the lower half of his face.
'So I'm in the same generation as Kakashi... that's great news!' I thought excitedly.
If I was in Naruto's generation, or worse, Boruto's generation, I would have little time to prepare for what was to come, but being in Kakashi's generation, I would have more than enough time to prepare for all the mess that would arise in the future.
Trying to better understand my current situation, I went to the scrolls that told the history of the clan, which was the scroll I had just read.
Reading it with the knowledge of the powers System had given me, it was quite easy to understand that what Kazuki Makami had awakened was not a simple Kekkei Genkai as everyone imagined, but that he had awakened his demonic power!
The wings that appeared on his back were the demon wings that all demons had, his ability to use jutsus that he didn't know could easily be explained by [Creativity Magic], his improved physique and intelligence could easily be explained by the possible Astaroth line that Kazuki Makami had.
Unfortunately, Kazuki Makami's son, "my father", was unable to awaken our clan's "Kekkei Genkai".
For normal people, although there are some doubts, the gradual disappearance of the Kazuki clan may seem like just bad luck, just like what is happening with the Senju clan, but for me, who already knows the plot and who the true colors of Konoha's leaders are, it was obvious that what was disclosed was not the full story.
If I were older and more powerful, I might even consider trying to get this information, but at my current level of power, even with the awakening of my demonic power, I'm still very weak... but even weak, I needed to better understand what I was capable of now.
So I got up slowly, observing the corners of the room more carefully and calmly than when I woke up.
The traditional Japanese style made entirely of wood gave me the impression that any slip-up would attract attention, and considering that I'm in a village full of ninjas with spy training, I needed to be discreet.
I went to the center of the room and closed all the wooden windows, lowering the translucent paper curtain. I made sure that no one was watching me through the crack in the door, and only then did I begin to concentrate.
Unfortunately, I had no idea how to sense if someone was watching me, so this was the best I could do.
'Let's start with the most basic thing... my wings. I thought.
I concentrated on my back, trying to feel the demonic energy running through it. A slight warmth built up in the region of my spine, and then... fuuush... a pair of black wings protruded smoothly from my back.
The wings were large, made of solid energy, and even without flapping, I could already feel the surrounding air being slightly pushed by their presence.
'Wow... they really are real. I thought excitedly, hardly believing it. They were just like the demon wings in DxD, made of pure magic, ethereal in appearance but with a physical presence.
I raised my arm, looking at the outline of the wing from the side. The texture seemed to be made of shadow and compressed smoke, but my touch told me that they were as firm as muscles.
With an effort of will, I imagined myself floating and in an instant my feet were off the ground and my body was floating!
The sensation of flight was incredible, making me want to fly aimlessly around the world, so I made the wings disappear and reappear twice, until I mastered the process. For the time being, flying would attract too much attention, so I put it aside.
'Time to test [Creativity Magic]...' I thought.
I closed my eyes and imagined the simplest and most generic magic in all of gaming, a small fireball, like the ones that RPG mages cast.
I concentrated the energy I felt coursing through my body, and surprisingly I felt that it wasn't just chakra...
It was as if chakra and mana were mixed in my body. The flow was more intense than the body of a five-year-old child could ever handle.
I raised my palm and activated the ability.
Fwop.
A small floating flame appeared above my hand, the size of an apple. The flame didn't burn my skin, but the heat was real. The wooden floor reflected the orange glow in soft waves. I held the shape for a few seconds, then extinguished it with a snap of my fingers.
'That was easy... and took less mana than I expected.' I thought intently.
Considering the anime shows, where doing just one fireball jutsu already heavily drained children like Sasuke and Obito, the amount of mana I spent to do it was very little.
Now, for a more difficult test, wanting to understand my limits, I closed my eyes and thought of a kunai. Not just the thought of a generic kunai, but a specific kunai from Enzai's memory, with weight, a metal frame, a sharp blade and perfect balance.
Considering that this skill depended on how well I imagined what I wanted to do, I tried to be as specific as possible.
When I activated [Creativity Magic] again, I felt the difference immediately. A brutal drain of energy hit me, as if every detail of that kunai was being carved directly from my life energy.
With a metallic clang, a kunai slowly formed in the air, dripping sparks as if it had just come out of the forge. It fell to the ground with a dry *clang*.
Curious, I picked it up and examined it.
This kunai was perfect... with impeccable balance, and apparently fully functional.
Sure, I didn't have enough knowledge to test how good it really was, only superficially, but from what I saw, it was even better than I imagined!
But my body was breaking out in a cold sweat.
'So physical objects consume a lot more mana than simple elemental spells... that's going to be important to remember.' I made a mental note of this information.
Before I finished my tests... there was still one skill missing. The most enigmatic of the three.
'[Kankara Formula]...' I thought.
The energy around me seemed to respond to the name of the skill, as if the air itself had become denser, more mathematical. I closed my eyes and breathed in slowly, trying to focus on something simple. Very simple.
I lit the fireball above my palm again, but this time I activated the Kankara Formula on top of it.
Instantly, the floating flame stopped oscillating. Red and green lines appeared around the sphere of fire, like graphs. Circles, numbers and symbols began to orbit the magic like the projection of an equation.
[Temperature: 423°C...
Mana consumption: 1.2 per second...
Stability: 89%...
Shape: Sphere, radius 6 cm...]
I was seeing... the structure of magic. As if fire were visible code. It was like seeing the backend of reality being unraveled in front of me.
Curious, I played with one of the variables.
I changed the "shape" of the flame from a sphere to a ring. The equations rearranged themselves automatically and, in the blink of an eye, some of my remaining mana was consumed and the fireball flattened out into a flaming ring spinning above my palm. The heat spread around the edge and the mana consumption dropped slightly.
"That... is very OP!" I whispered with a fascinated smile.
I closed my hand and canceled the spell, the formulas shattering into luminous particles. Now it made sense what was described in that skill: the ability to turn any phenomenon into an equation, and from that, manipulate it.
"If I can use this on other people's jutsus... can I reprogram their attacks?"
That simple idea sent shivers down my spine.
Modifying, nullifying, duplicating or redirecting other people's ninjutsus... that was the true potential of this technique. Once I understood how something worked, it was no longer a threat.
The Kankara Formula was like a reality debugger.
I closed my eyes and laughed, a little startled by what I had just discovered.
Tired, I sat up in bed panting slightly, but a broad smile formed on my face.
This world, which at first seemed like a death sentence, now seemed full of possibilities. I wasn't just a generic ninja, or even a genius like Kakashi.
I felt that I was something even better.
Kazuki Makami was once considered a very powerful genius, but considering what I know from DxD, this powerful patriarch of my clan showed only a fraction of the potential that a true Devil had!
