Chapter One
Everyone was standing on the edge of one of the tall buildings in the village, shouting almost in unison at Naruto, who was painting the faces of the four Hokage with bright red paint. It was not just ordinary vandalism, but a huge absurd mural that could be seen from every corner of Konoha. Children were laughing, some were mocking, and the adults were sighing in annoyance and shouting.
I was standing there watching the scene silently. I won't deny that I felt annoyed as well. How long would he keep up these kinds of antics? It was truly embarrassing. The whispers of the people around me were clear:
— Oh my God, look at all this.
— Hey kid, stop doing this every day!
— Why can't you be calm like his sister?
— Look at her, how calm and wonderful she is. Why can't he become like her?
I sighed slowly and said to myself: Yes… Naruto, my foolish brother.
But the truth was that all of this was not normal for me. I did not belong to this place… or rather, I had not belonged to it before.
It all started when I was just a university student living a quiet life, divided between lectures and home. I was not very social, but I was not isolated either… my world was simple and clear. However, there was one thing I was deeply attached to… the Naruto series.
I was one of its biggest fans. I watched the anime over and over again, and I owned a small library containing all the manga volumes. I never ignored any work related to it without checking it out. It had been a part of my childhood and adolescence, a world I turned to whenever my chest felt tight.
But one day, I felt that I had truly grown out of all of that. I told myself that I needed to mature, to organize my room, and remove the posters covering the walls, and even the manga volumes. I actually did it. I carefully took down every poster, as if I were saying goodbye to a part of myself, then placed the volumes into a large box.
And while I was about to carry the box to the attic, I climbed the stairs while holding it. But it was heavier than I expected. I suddenly lost my balance, my foot slipped, and I fell onto my head. The box fell directly on top of me and slammed hard into my face.
Then… darkness.
I don't know how much time passed. But I heard an annoying voice breaking through the silence:
— Naruko… Naruko! Hey, wake up!
I slowly opened my eyes to see a familiar face in front of me… spiky blond hair, bright blue eyes, and childish features full of irritation.
Naruto.
I rubbed my eyes, then gently touched his face and said in astonishment:
— Oh my God… I can't believe it. This cosplay is extremely realistic. You're really good.
He looked at me with a funny expression, a mix of confusion and annoyance, and said:
— Huh? Get up, idiot, we don't have time!
I sat up slowly and began looking around me. The room was not my room. The walls were wooden, the floor was simple, and the furniture was modest or barely there…
I shouted:
— What? Where am I? What is this room? What am I doing here?
He said impatiently:
— Come on, Naruko, stop pretending.
I pointed at myself in shock:
— Naruko? Me?
I turned toward a mirror placed on the wall. I approached it slowly, feeling a shiver run through my body. What I saw was not my face.
I was no longer the girl with black hair and green eyes. In front of me was a small child with blond hair tied on both sides and clear blue eyes. I looked very similar to Naruto, except for the three lines on his cheeks… I didn't have them.
I touched my face in confusion, then pinched my cheek hard. I felt pain.
— This isn't a dream…
Naruto said in annoyance:
— Fine, I'm leaving without you.
And he left the house, leaving the door open behind him.
I stood in the middle of the room, understanding nothing. Did I die? Is this a long dream? Am I in a coma?
Suddenly, a transparent blue panel appeared above me, like a small screen floating in the air.
[System: Welcome to the world of Naruto.]
[System: Your last wish has been activated.]
I shouted:
— What wish are you talking about?!
[System: To become part of the world of Naruto.]
— What?! Is this a joke? That was a childish wish! I was just a little girl dreaming! Send me back to my world. I don't want to be a shonen heroine. All I want is to graduate, work, get married, and live a normal life!
[System: Returning is impossible. You are here as part of this world.]
I screamed in my mind: Damn you, system!
[System: Heard. Ten strength points have been deducted.]
I froze.
— Wait… what? Can you read my thoughts? And what are these points?
[System: I can read your thoughts. You were born in this world as an extra character, "the hero's sister." You have no main role in the story unless you possess strength points that make you special and visible to people.]
[System: You do not possess the Nine-Tails' power like Naruto, nor the eyes of the Uchiha. You are a weak character with no level or power.]
I felt as if something inside me was being crushed.
— What do you mean nothing?!
[System: You must work hard and follow daily events to survive in this world… and make yourself a remarkable person.]
I fell to the floor. My hands were trembling.
— I want to go back… I want my family… my life… I don't want this.
[System: Error… Error… Danger.]
I quickly raised my head.
— What do you mean danger?
[System: If you continue thinking this way, you will die before the story begins.]
Coldness spread through my limbs.
— I will die? And if I die, will I return to my world?
[System: No. You will disappear forever. Try not to die.]
Disappear… forever.
This is not a world for spectators. It is a world filled with battles, wars, and monsters. Even side characters die without anyone ever mentioning them.
I took a slow breath.
— Fine… how old am I now? And why am I Naruto's sister? And what exactly is my role?
[System: Too many questions.]
[System: Your current age is six years old. This role was chosen because it was your wish. Your current role: nothing. There is nothing special about you that deserves to appear.]
I bit my lip.
— And what do I have to do so that I don't die?
[System: Daily task list to strengthen abilities.]
[System: Tasks:
— Run around the city ten times.
— Climb heights ten times.
— Basic endurance exercises.
— Chakra control training.]
I stared at the list in shock.
— What?! All of that in one day?! I'm a six-year-old child! I'll die on the first task!
[System: Ten points deducted. Current total: 100 points.]
I shouted:
— Stop! Don't deduct anything! I was joking!
[System: ...]
I pressed my head with my hands. This is not a dream. Not an illusion. I am really here in Konoha. Before the beginning of the official story, during the childhood era.
If I die now, there will be no reset. There will be no dramatic scene. I will simply disappear.
I slowly stood up and looked at my small hands.
— Fine… if this is how it has to be… then I'll play by the rules.
[System: This decision increases the probability of your survival.]
I sighed.
— One last question. Can I become stronger?
There was silence for a few seconds, then the words appeared:
[System: The probability is not high. But it is not impossible.]
A faint smile appeared on my face.
I was just a university student dreaming of a normal life. And now I'm trapped inside an anime, with no power, no advantage, and a system threatening me with death.
This is not an ordinary shonen. This is a harsh world, and if I want to survive… I must turn from a background character… into someone who cannot be ignored.
I raised my head toward the blue sky outside the window.
— Alright then, Naruto world… I won't die easily.
[System: Objective recorded. Path initiated.]
And so my story began. Not as a spectator… but as a player in a merciless arena.
