Naruto: This Genius is Somewhat Ordinary-Chapter 391

"...So I really am invincible?"

Fujimoto Tōma felt the power flowing through his body and glanced at the figure collapsed on the ground not far away. Ōtsutsuki Kaguya could no longer rise.

He walked toward her at an unhurried pace.

"Why..." Kaguya asked weakly, disbelief and despair tangled in her voice. "Why can you use the Rinnegan’s abilities?"

"Because once you’re strong enough," Tōma replied calmly, "every power has rules behind it. I simply understood those rules and applied them."

Kaguya fell silent.

It sounded simple. Too simple.

But who in this world could actually do such a thing?

What Tōma described wasn’t the Sharingan’s imitation. The Sharingan merely copied chakra flow and hand seals, recreating techniques by mimicking their outward form.

Tōma’s method was different.

He didn’t copy.

He understood.

He grasped the essence behind an ability and reproduced it directly, even if the method differed. Just as no Mangekyō Sharingan could ever replicate Rinnegan techniques, yet Tōma could observe them once and unlock their governing logic.

Seeing the confusion in Kaguya’s eyes, Tōma continued.

"You know the Sage power your son, Ōtsutsuki Hagoromo, mastered, right?"

Kaguya nodded slowly. She didn’t understand what Sage techniques had to do with this, but she listened.

"Hagoromo’s Sage Mode came from mixing Ōtsutsuki chakra with natural energy," Tōma said. "There’s nothing inherently special about it. It’s powerful because the quality of Ōtsutsuki chakra is absurdly high."

"And this explains Shinra Tensei?" Kaguya asked.

"Patience," Tōma said. "A true Sage state should have defining traits. Those traits usually come from the species itself."

He paused, then asked, "Do you know what a leafcutter ant is?"

Kaguya frowned.

Tōma waved it off. "Never mind. You probably don’t even understand human biology. A leafcutter ant can lift over fifty times its own weight. No chakra. No natural energy."

"And?" Kaguya asked, confused. "Fifty times an ant’s weight is trivial."

"What if I told you," Tōma said with a faint smile, "that a Sage state based on that trait amplifies the user’s original strength first?"

Kaguya’s pupils shrank.

"So before chakra or natural energy is added," Tōma continued, "the base strength is already multiplied. And once chakra enters the equation... it’s not fifty times anymore."

Kaguya finally understood.

"And leafcutter ants aren’t even the strongest example," Tōma added casually. "Some creatures can lift nearly a thousand times their body weight without any enhancement at all."

Silence stretched between them.

"...So there exists a Sage state that allows the user to rapidly comprehend abilities?" Kaguya asked at last.

Tōma nodded. "Yes. Now let me ask you something. Before chakra ever existed, what was the greatest difference between humans and animals?"

Kaguya didn’t answer.

"Thought," Tōma said. "Intellect."

Humans weren’t strong. They weren’t fast. They weren’t durable.

But they thought.

"They created tools. And after chakra appeared, they created ninjutsu," Tōma continued. "Techniques that gave you trouble. Eight Gates. Flying Thunder God. I didn’t invent those."

Kaguya looked away.

She couldn’t deny it.

"So the Sage state that belongs to humans," Tōma said softly, "is understanding itself. It isn’t the strongest. It isn’t the fastest. But it lets the user comprehend anything... and then create anything."

He glanced at her. "That’s why I remembered Shinra Tensei, analyzed it, and used it. That’s all."

Human Sage.

The Sage path that truly belonged to humanity.

Tōma had wondered for a long time whether humans had their own Sage state. Other creatures did. Why not humans?

He found the answer at the edge of death.

But there was a paradox.

To fully master Human Sage, one needed to understand all fundamentals. And understanding everything was nearly impossible. Tōma had only achieved it through extreme fusion and life-or-death insight.

Teaching it directly?

Unrealistic.

Yet maybe it wasn’t impossible. Perhaps Human Sage didn’t begin at the level he stood at now. Perhaps its true strength lay in learning, gradually climbing toward comprehension.

Tōma smiled faintly. Maybe he’d taken the longest, hardest route possible.

"...I see," Kaguya murmured. Enlightenment flickered in her pale eyes, followed immediately by deeper confusion.

It was too late for her.

She had eaten the God Tree’s fruit. No one had ever taught her. No one had ever corrected her.

Perhaps that was why she had been sealed by her sons... and now stood here again, on the brink of another defeat.

"You’re going to seal me now, aren’t you?" Kaguya asked quietly.

She had no will to resist left.

All her abilities had been seen. Which meant all of them could be used against her.

Tōma sighed. "You’ve given up already?"

He had half-hoped to fight her again once she fully recovered. But this was fine too.

"As you guessed," he said calmly, "everything you can do, I can do as well."

He understood now. Possessing kekkei mōra didn’t automatically grant every kekkei genkai. It only made them far easier to derive. Different abilities required different chakra ratios.

In theory, far more bloodline abilities existed than those recorded.

But that could wait.

Eventually, he would return to his origin and refine everything he had gained.

For now, he felt something else creeping in.

Emptiness.

This war had pushed him from start to finish. From Kage-level opponents to Edo Madara, Six Paths Obito, Six Paths Madara... and finally Kaguya herself.

It had been exhilarating.

And now?

Nothing remained.

The other Ōtsutsuki might appear someday, but Tōma doubted they would surpass Six Paths Madara, let alone challenge him now.

The road ahead looked... lonely.

Still, he would keep moving forward.

Strength didn’t need a reason. Wanting it was enough.

Tōma stepped in front of Kaguya and placed his hand on her abdomen.

The world shifted.

They returned to the shinobi world.

Instantly, vast torrents of chakra began flowing from Kaguya into Tōma.

"That’s... mine..." Kaguya whispered, eyes reddening, like a child watching her favorite possession being taken away.

But she didn’t resist.

She couldn’t.

Before an adult, a child had no choice.

Tōma ignored her cries, calmly absorbing the chakra. What Kaguya carried was nearly the entire world’s chakra.

99.99 percent was close enough.

The transfer took a long time.

When it finally ended, the crimson Rinne-Sharingan on Kaguya’s forehead closed for good. Her body withered, consciousness fading.

Tōma exhaled slowly, feeling the overwhelming chakra inside him.

"No wonder Madara burst," he muttered. "No one else could hold this much."

He could.

Barely.

One more world’s worth might push him past the limit. But even then, he would fare better than Madara ever could.

Tōma’s gaze sharpened.

There was one final thing he had always intended to do.

Convert all chakra into natural energy.

And return it to the world.

Restore it to its original state.
