Chapter 24: Ultimate Genjutsu.
Time Skip – Two Months Later
Life at the Academy went on as usual. Nothing out of the ordinary had happened since that incident with the Root spy. Tsunade remained engrossed in her experiments, and I continued to refine my training.
By now, I had achieved what most wouldn't dream of even as full-fledged shinobi—I could perform all my Wood Release techniques without a single hand sign.
There were still about four months left before the graduation exam. I was determined to graduate in just one year. Kakashi would graduate around the same time, if the timeline still followed what I remembered from the anime.
But for me, early graduation wasn't just about showing off—it was about freedom. I wanted the liberty to move through the world and start unlocking my full potential. Missions meant movement, and movement meant opportunity. If anyone tried to tail me on those missions with ill intent? They'd end up buried underground. Literally.
Taijutsu? Check.
Ninjutsu? Well beyond check.
So now, it was time I turned my focus toward something more elusive—genjutsu.
I needed to create a unique genjutsu technique, one that no other shinobi could copy. Sure, I had near-immunity to basic illusions thanks to my chakra control and natural energy balance. But I knew even I wasn't fully immune—especially not to Eternal Mangekyō Sharingan-level genjutsu.
Not yet.
But when I completed my perfect Sage Body, I would be. Because at that point, my body would function primarily on natural energy—and genjutsu that manipulates chakra pathways and nervous signals becomes useless when there's no conventional chakra to manipulate.
Still, until then, I needed my own trump card in the genjutsu domain.
I approached Tsunade in her lab.
She was in the middle of her work—white coat slightly bloodstained, gloves still on. A dissected corpse was laid out on the table, likely another death row shinobi donated for "research."
She glanced at me when I walked in, expecting hesitation, maybe even fear.
I gave her none.
Her eyes studied me closely. She didn't say anything, but I could tell from her expression—she knew. She knew I'd already killed. She didn't question it. She simply nodded once, as if confirming her own resolve.
After a few seconds of silence, she led me to a room deep within the Senju compound. The air changed the moment she unlocked the seals—a library of scrolls, hundreds of them, some faded, others freshly copied.
"This is everything," she said. "Every scroll passed down through the Senju. Fuinjutsu, chakra theory, medical jutsu, and—"
"Genjutsu?" I asked.
She nodded and gestured to a section filled with red-sealed scrolls.
I immediately unsealed my own storage scroll and began absorbing everything. Once the genjutsu scrolls were securely stored, Tsunade resealed the archive and returned to her lab, saying she had entered a "crucial phase."
I returned to my room and laid out the scrolls. For the rest of the evening, I studied.
I wasn't just learning techniques—I was understanding them. Their structure, triggers, weaknesses. How they tied into the five senses. How auditory genjutsu differed from visual illusions. How pain and chakra disruption could break most of them—but not all.
Then I came across one scroll that made me pause.
It was written by Tobirama Senju himself.
It focused entirely on the Uchiha clan's Sharingan-based genjutsu. From basic illusions to Tsukuyomi-tier control mechanisms. It even had detailed diagrams showing how the EMS warped reality perception, with notes on how to potentially counter them through chakra interference or natural energy redirection.
"So Grandpa Tobirama really was preparing for war…"
I absorbed every word like scripture. This wasn't paranoia. It was preparation.
But before I could finish all of it, the sky had darkened.
I resealed the scrolls and headed out.
Tsunade was already at the table eating. I joined her, and we ate quietly. Afterward, I once again infused her with nature energy.
To my surprise—no, to my satisfaction—her body could now handle even more of it than before. I fed her as much as her system could bear, carefully monitoring her chakra network the entire time.
At this rate… she wouldn't need two more years. One year. That's all she'd need now. Whatever she was doing in that lab—it was accelerating her recovery.
Later that night, I sat in my bed and meditated. Natural energy swirled around me. It entered me more easily now—my body had adapted, strengthened, evolved.
If Tsunade needed one more year, then I only needed three.
At ten years old, I'd have the perfect Sage Body.
At thirteen—the age the Third Great Ninja War should begin—I would be prepared. Not just to survive, but to dominate.
With Sage Mode, Wood Release, taijutsu mastery, and the unique genjutsu I planned to create, even the tailed beasts might fall before me.
