Naruto: Dual-Pupil Uchiha

"Hikari, what's going on?"

Genya looked at Hikari's hurried appearance, and a glimmer of light flashed in his eyes.

If nothing unexpected happens,

The thing he had been anticipating was finally coming true!

"Genya-sama, my brother and I have successfully developed the cell serum. It's ready for injection, I hope...!" Senju Hikari looked at Genya, her eyes full of expectation.

This was the most important step of her life, and she wanted Genya to personally inject it for her!

Uchiha Kinya and Uchiha Shin exchanged glances, both their eyes filled with hope. They were also excited that the cell serum had been successfully developed.

Both of them were filled with envy!

They had experienced firsthand Genya's strength, and now, they also wanted to improve their physique. Especially Uchiha Shin!

He felt that if he didn't increase his strength soon, the future ninja world—no, the future Uchiha clan—would have no use for him!

As the captain of the Uchiha Police Force, he wanted to keep his strength at its peak, or even surpass his current self.

So,

Uchiha Shin impatiently asked, "Hikari, how long will it take for my cell serum to be ready?"

When he asked this, Uchiha Shin didn't even realize that his tone carried a bit of flattery!

After all!

Right now, Hikari was the key to his strength.

In fact, this wasn't the first time he had asked. Every time, he had been filled with hope.

"Uncle Shin, your cell serum might take a while. Your cells have just begun to show compatibility with Uzumaki cells. To perfect the serum, it will take at least six months to a year!" Hikari looked at the expectant Uchiha Shin and spoke slowly.

This was still her conservative estimate. If Uchiha Shin's cells showed rejection even after reaching perfection, they would need further adjustments!

Some medical details, she couldn't explain clearly to the Uchiha.

"Another six months?" Uchiha Shin nodded regretfully.

"Let's go!" Genya glanced at Hikari and stood up, heading toward the Uchiha hospital.

In the underground laboratory, Genya stared at the two golden vials of medicine, his eyes lighting up!

From now on, They would have two more powerful allies, and Hikari and Hayashi's talents weren't bad either!

"Who will inject it first?" Genya asked, looking at Hikari and the two from the Senju clan.

"I'll go first!" Hayashi stepped forward. When faced with the unknown, he was always the first to step up and try things out for his sister.

"Brother," Hikari said, her eyes filled with worry.

Hayashi nodded. "Don't worry, sister. I trust the medicine you created!"

Hayashi was confident in the medicine his sister had made, so he turned to Genya. "Genya-sama, please begin!"

Genya nodded.

However, Hikari kept holding onto Genya's arm tightly, her body still trembling. It was clear that she wasn't fully confident in her own medicine yet.

"It's okay!" Genya gently patted her hand and said softly, "Even if something happens to your brother, you're here, and you can still help him!"

"Mm!" Hikari nodded seriously.

Then, Genya didn't hesitate and injected the medicine into Hayashi's shoulder!

If there was any strange reaction, he would immediately cut off Hayashi's arm!

As the medicine was injected, Genya saw the muscles in Hayashi's arm start to bulge, as if the cells being injected were beginning to merge with his own!

Huh?

Senju Hayashi furrowed his brows.

"Brother, does it hurt?" Hikari looked at her brother's tightly furrowed brows and spoke with concern.

Her tone carried worry.

She knew that when Genya absorbed the cells, it was so painful that it nearly killed him!

"It's just my arm hurts a little, feels a bit swollen," Hayashi said, feeling the pain in his arm. It wasn't as bad as his younger sister had thought.

Genya used his Dual Pupil to peer through Hayashi's skin and into his body!

He saw the green light inside Hayashi's body, which was promoting the fusion of cells. And the process was moving quickly! It even activated a certain power within him—chakra began gathering in his arm, and streaks of green light became brighter and stronger.

Then, Genya noticed something unusual!

In the basement, with its brick and tile structure, a plant had actually broken through the floor tiles and was slowly growing!

He could see that the plant was growing because of the chakra from Hayashi's arm!

"Eh? Is this Wood Release?" Genya's eyes sparkled with a bit of light, and he became more nervous.

He knew that some ninja who merged with the First Hokage's cells and gained Wood Release ended up turning into trees!

What would happen to Hayashi?

This might be his Kekkei Genkai awakening—there shouldn't be any problems, right?

"Hayashi, control your chakra and stop releasing it, or your tree might break through the lab!" Genya reminded him.

Hayashi quickly complied and sealed the chakra back inside his body!

Sure enough, without the chakra's nourishment, the branches and vines stopped moving completely.

"Wow, I didn't expect that injecting the Uzumaki cells would stimulate the Senju bloodline and activate the Wood Release kekkei genkai!"

Genya's eyes gleamed. This discovery was huge!

Even if Hayashi didn't reach the level of Senju Hashirama, just having a fraction of his power would make him one of the top ninjas!

The Senju clan—when he fully awaken this Kekkei Genkai, he could become as powerful as the First Hokage, shaking the entire ninja world!

"Genya-sama, what's happening to my brother?" Hikari asked in confusion.

"It should be the fusion of the Uzumaki cells with the cells inside him, which broke a certain restriction within your brother, activating his Kekkei Genkai!" Genya spoke softly, a smile on his face.

"Is this Kekkei Genkai very strong?" Hikari, although she understood some aspects of Kekkei Genkais, wasn't very familiar with her brother's particular ability.

"It's the same Kekkei Genkai as the First Hokage. Do you think it's strong?" Genya answered with a laugh.

"So, that means my brother can become very strong, and he can help Genya-sama?" Hikari's eyes sparkled, and she looked at her brother with longing.

Her brother could get stronger now and could work with Genya!

Genya nodded with a smile.

"Genya-sama, I think it will take about three months to fully fuse these cells, and then I can become stronger and help Genya-sama!" When he heard that he could become strong, Senju Hayashi's face lit up with excitement.

He had always felt inferior in the past, especially since he was older than Genya by several years, but much weaker in strength. He had always felt ashamed that he couldn't be of help to Genya.

Even though his sister was already working for Genya, he had always felt out of place!

So, he kept a low profile and worked hard to train during the day.

Now, hearing that his awakened ability was powerful, he felt he finally had a chance to prove himself!

Genya nodded and then turned his gaze to the obedient Hikari: "Hikari, it's time for me to inject the cells into you!"

Hikari blushed slightly and nodded. There was a hint of determination in her eyes.

If her brother could awaken his Kekkei Genkai, so could she!

She wanted to help Genya more.

Then, she removed the sleeve of her robe, revealing her delicate arm.

Genya didn't hesitate. Taking a deep breath, he injected the cell serum into her arm!
