The accessories.

"I have a bit of confidence in Busoshoku, I don't know if I can do Kenbunshoku, and I have no idea about Haoshoku.

I get excited because I remembered that I received other things in the box.

I check the inventory:

Concentration Ring - Level 4 = Helps to have more concentration but consumes mental energy; abusing this can lead to consequences such as fainting.

Resistance Ring - Level 3 = Helps to maintain more endurance but drains the body's energy; abusing this can lead to consequences such as fainting.

Vitality Ring - Level 2 = Helps to maintain vitality; abusing this can lead to consequences such as hidden injuries, reduced lifespan, regression of stats, and if you accumulate too much damage, you will die.

It just seems like one word to me, 'incredible,' my path to being OP is not cut off yet, although the last ring is a bit scary, but if I infer correctly, it can help me be harder to kill; too bad it's only level 2 (I don't even know what level of power those have).

If other ninjas heard his thoughts, they would run to beat him up since in the battlefield that little bit of vitality he maintains could save his life in a critical moment.

'Well, I think I will go to sleep since tomorrow I have to start training.' A house is not built just by imagining it.

With that in mind, I go to sleep.

-The next day-

I get out of bed and prepare to take a shower, then I eat ramen (it's the most affordable food).

'In my agenda for today, I have to run 1500m, do 150 squats, and 100 push-ups.'

Author's Note: I'm making this up; I don't know if a 5-year-old can do that, but let's take into account that the kids here have stronger bodies.

I'm not an athlete; I'm just starting to train, so I complete this routine over the hours. I'm surprised that I can do it; in my previous life, I could never have imagined doing this even if I tried.

I finish eating and head to the exit. I should mention that the house is quite simple, with 2 rooms, a bathroom, a kitchen, a living room, and a dining room; although it's not big, it's not that small (what are you talking about, that's big for one person).

I go out the door and start to walk down the avenue.

-A few minutes later-

hah ahh hah ahh hah ahh

'It's the first time I've run this much with this body; even though I managed to do 700m, my throat is dry and hurts, and my legs hurt a bit.'

In this state, I return home, drink water, rest for a while, and prepare to do 50 squats.

After finishing, I sit down with pain in my legs.

I rest for a while and start with the push-ups...

I couldn't do more when I was on the 7th; my arms gave out.

I made the effort to get up and go to my bed to sleep.

-In the afternoon-

I woke up, but all I felt was pain, especially in my arms and legs.

I lay there in pain and tried to sleep again, and I fell asleep.

-The next day-

I got up with pain, although it was less than yesterday; I could walk. I went down to the kitchen to eat; I was terribly hungry, probably because I couldn't eat lunch and dinner yesterday.

Then I left the house to continue training; the results were that I only managed to run 500 meters, do 40 squats, and 5 push-ups.

I'm starting to doubt if I will make it.

This situation lasted a week<

A week has passed since I started training; at first, it was terrible, but I'm starting to get used to it, and I don't get as winded anymore; I breathe evenly. Overall, I'm doing quite well, or at least I think so, because I don't know if this pace will be enough in this world.

Today, while I was doing my routine running along the sidewalk, just turning the corner, I bumped into someone else, specifically a girl.

I was running without thinking about anything, so I didn't take precautions when reaching the corners.

I felt a strong pain in my forehead; I grabbed my forehead and looked up to see a girl.

She was dressed in a white shirt and feminine-style shorts, had blonde hair, a slender body, and striking three whiskers on each cheek; she seemed to be the same age as me.

She feels both familiar and unfamiliar at the same time, right? If that's what you're thinking, then you're right; it's Naruto, or should I say Naruko.

How did this happen? I wonder the same.

At what moment in Naruto's story did a butterfly effect cause this?

These questions keep me thinking when I go to sleep.

And this has led me to wonder how this happened, at what moment, what changes occurred, and if Sasuke will be the same.

She gets up, holding her forehead in pain from the collision.

"Ayayayai"

She says with tears at the corners of her eyes.

I get up, enduring the pain in my forehead.

"Are you okay?"

I say with a gentle smile on my face; it hurt, but maybe it's human instinct, but I feel empathy for her.

She stares at me for a few seconds, seeming to forget the pain.

Involuntarily, she says, "No, it's fine." She smiles in response.

Suddenly, a shout is heard in the background.

"Narukoooo"

"Damn it"

Naruko quickly gets up in panic.

"I'm sorry, but I have to go." She quickly escapes from the scene.

I watch her leave quickly while still standing in the same place.

Well, that's what happened to me today.
