Naruto: Becoming a master taijutsu using martial arts.

That is it. I would talk about the Will of Fire as much as I could every time I had the chance to be in front of the Third Hokage. Well, the best way to do that is:

"My dream is to become Hokage!" I tried to declare with as much confidence as possible before bursting into a fit of laughter.

I covered my mouth to avoid drawing anyone's attention. I definitely need to improve that, but I have time.

I would present myself as a young orphan who wishes to become Hokage to protect the village, just like the Fourth Hokage did, and to honor my father's legacy. With some luck, I could pass as a dedicated and prodigious orphan that the Third Hokage would value.

Adding other events to the papers would have to wait. Things could change and there is no point in starting to plan for Akatsuki, Zetsu, and such things right now.

"What I need to focus on is what I can do to get stronger."

To be honest, I didn't have much to work with. The main thing I could do was train my body. I had always been lazy, going to the gym a few times a week just to avoid getting fat and to balance out my terrible smoker's lifestyle.

I knew the theory behind some things in the Naruto universe, like the process of chakra control training. I even remembered how the Rasengan was developed and the hand seals for two techniques. One was the Kage Bunshin—it was simple, and no fan could possibly not know it. The other was the Fireball Jutsu, which I knew because I once had a competition with a cousin to learn the hand seals for a Naruto technique.

But knowing what chakra was wasn't enough—I had no idea how to use it or how to feel my own chakra. I hadn't felt anything different in the past few days.

"Wait… Could it be like that?" I widened my eyes as realization struck.

Chakra was the union of spiritual and physical energy or something like that. I didn't know how to use it, but a scene from Dragon Ball came to mind—Gohan teaches Videl what Ki was. Even though Ki and chakra weren't the same thing, I decided to test if they worked similarly.

"If I remember correctly, the process was to stay calm and try to release the power inside me little by little," I murmured, putting down the pencil and sitting in a more comfortable position. "It must be similar to meditation."

I closed my eyes and tried to clear my mind of random thoughts. Keyword: tried.

Apparently, of all the things I could have brought into this new life, my ADHD came along too. Trying not to think about anything brought the most random thoughts possible, like wondering what bra size Tsunade wore or whether the Third Hokage only smoked tobacco in that pipe—because let's be honest, some of his decisions were highly questionable.

"Damn… This is harder than it seems," I said, frustrated after a few moments.

I took a deep breath. I couldn't afford to get irritated, and I knew that, but it was frustrating. What if I didn't have the ability to use chakra? I wasn't as dedicated as Rock Lee—I'd probably end up dead. What a mess.

"Calm down… I am Hoshino Kenshin, and I will do this." I tried to steady myself and soon decided to take another approach.

Clearing my mind of stray thoughts was probably impossible, but what I could do was try to focus those thoughts on something specific.

Once I calmed down, I focused all my attention on one simple thing: the rhythm of my heartbeat. I felt every beat of my heart and synchronized my breathing with it until I reached a point where all I could sense was the blood pumping through my body.

No, it wasn't just blood… I felt something else, something trapped in my heart, wanting to break free. Slowly, I began to feel this warm sensation spreading, and when I finally sensed it, I couldn't believe I had never noticed it before.

It was as if I had lived my entire life with an extra finger and never realized it. That warm sensation spread throughout my body, and I could feel points of tension in me relaxing as it flowed.

'This… is this chakra?'

It was nothing like I had expected. It felt like I had another kind of blood coursing through my body at that moment. Unfortunately, my admiration caused me to lose focus, and the chakra stopped flowing.

However, I could still feel it there. I knew I could do it again if I wanted but I felt exhausted, it was like I just ran a marathon.

"Hell yeah! This is amazing!" I exclaimed, lying back on the floor with a smile on my face.

I really have chakra. I knew I was in Naruto's world, but this was undeniable proof.
