At the Konoha Hospital, Uroko waited anxiously in the waiting room with Yakumo by her side.

Some time later, the doctor arrived with Yakumo's medical report.

When her name was called, Uroko went up to the doctor with Yakumo.

The doctor seemed surprised as she looked over Yakumo's medical report. After all, just a few months ago, her diagnosis was of a child with a weak body, something that couldn't be resolved even with healing jutsu.

The only person she thought could help at this point was Miss Tsunade, but she wasn't in the village. So, how did Yakumo improve so much in such a short time?

"How is my daughter, Doctor Tsubasa?" Uroko asked, anxious as she held Yakumo's little hand.

"It's kind of like this, her diagnoses indicate that she has magically improved a lot, her body..." Tsubasa paused. "Her physical condition is practically that of a normal child, her old health problems are gone... Tell me, has she met Miss Tsunade?"

"No, there hasn't been such a thing," Uroko denied as she processed what she had just heard.

"No? That's surprising, your daughter is very lucky!" Tsubasa exclaimed, losing her composure slightly.

Tsubasa was, after all, the doctor who had been following Yakumo's medical reports and had even conducted some tests before. She had felt that it was a pity that such a lovely little girl had such a weak body compared to other children, but now, here was the same little girl a few months later with a medical diagnosis that seemed to defy everything she believed.

Of course, she knew that miraculous things could happen once some X factor occurred, but until then, they didn't know what exactly that X factor was, not even the girl's parents seemed to know. They just reported that suddenly, Yakumo had a fever, but then, magically, after the fever was gone, she got better every day.

"So... My daughter's health..." Uroko asked somewhat insecurely.

"It's all good," Tsubasa snapped out of her reverie and reported, "As I said before, everything indicates that she is now as healthy as a normal child."

"Waahh!" Upon hearing this, Uroko had an emotional outburst that made her cry.

It was as if a huge weight had finally been lifted off her shoulders.

"Mommy?" Yakumo, who felt the tighter grip on her little hand, caught her mother's attention.

Maybe because she heard her daughter's plea, Uroko let go of Yakumo's little hand and, in the next instant, knelt down and hugged her while crying heavily.

Yakumo was taken aback. She didn't know what to do seeing her mother cry so suddenly.

Seeing her mother so emotional, Yakumo felt a tightness in her chest, not fully understanding the reason for the tears. Nevertheless, the overflowing love and happiness in Uroko's embrace touched her deeply.

While she was being hugged, Yakumo said softly, but as she repeated the same words, her voice became more teary: "Mommy, don't cry, don't cry, don't cry... Boo-hoo, boo-hoo, mommy!"

Mother and daughter hugged each other as they cried, but no one tried to comfort them or stop them.

When I got home, I heard about my little sister's medical report. Of course, I knew the reason for her improvement, but I pretended to be surprised. At the same time, I was genuinely happy.

Sure, I believed that pushing the limits of her endurance and strength attributes could help her, but until then it was just theory. Seeing her improvement in practice, confirmed by the doctors, brought a sense of validation and relief to me.

"Big Brother, teach me how to train?" Kumo asked me, then added, "Doctor Tsubasa said I need to start exercising to adjust my physique."

Actually, it wasn't quite like that. I heard from my mother before; the doctor just said that Kumo should play more, engaging in activities that demanded more of her physique, like playing tag, hide and seek, and so on.

However, I understood that my little sister must prefer to come to me and rely on me. After all, even at a young age, she understood a bit about how children avoided playing with her for fear of hurting her. Especially the children from the clan.

"Sure, I'll teach you some basic exercises," I said with a gentle smile as I ruffled her head. This time, she didn't try to avoid it and smiled brightly at me.

In the Dojo, Kumo was wearing more comfortable clothes. Remembering that I had done kids' yoga, I wanted to teach her that. It was something I had learned in my previous life as a child.

My mother was also present in the Dojo. From what I could see, even with the medical report, her concern had not completely dissipated...

Well, it was just the three of us, so it was fine, since it was our family's exclusive Dojo, rather than the Dojo open to the entire clan.

The poses I taught were the simplest, most accessible, and safest. Even my mother was by our side doing the same poses, which seemed to amuse Kumo.

As the real intention was for Kumo, I created fun names for each pose, like Sunflower Pose. I had her stand with her arms extended upwards like sun rays, gently rotating around the axis as if following the sun.

The next one, I called: Happy Tree Pose. Like before, she stood up, but with one leg bent and supported on the other leg, arms extended to the sides, gently swaying like the branches of a tree in the wind.

I could see that it was working by occasionally hearing her happy laughter, as well as the smile that never left her face even when she started to sweat.

In addition to these two poses, I taught three more that I called: Curious Kitty Pose, Bouncing Tiger Pose, and Smiling Cobra Pose. Each with its own benefits.

"This is fun, Big Brother~" She said to me with a smile as sweat dripped down her forehead.

I smiled back and said, "Don't overexert yourself, take a break when you're too tired."

"Mm." She nodded.

My mother beside us, who was doing the same kids' yoga exercises as Kumo, seemed more at ease when she saw that although she was sweating a bit, it wasn't too difficult to do.

After giving them attention, I went to make my own training schedule.

While training, I initially prioritized training my speed and agility, which indirectly improves my endurance.

Training speed is about moving quickly in a specific direction, which is what I did when running from end to end of the Dojo. Agility, on the other hand, is more about the ability to change direction quickly and efficiently, basically my ability to accelerate, decelerate, and change direction while maintaining control of my body.

Because they are so compatible, I can train both at the same time. After doing this for a few days, I learned the most effective way to increase both and, collaterally, my endurance.

At some point while I was training, I saw that both my mother and my little sister had stopped what they were doing to watch me train. I even heard Kumo clapping and cheering for me, which, by the way, I found very cute.

When they seemed to have tired of watching me train, my mother said she would start preparing dinner and Komo left with her, so I was alone in the Dojo.

'Now I can test the wind clone,' I thought.
