Naruto: Transmigrated as Obito with the System

"So this is the Mangekyō Sharingan…" Itachi muttered under his breath.

Despite obtaining this legendary power, there was no trace of joy in his expression.

His dearest friends, his brothers in arms, lay lifeless before him.

…And he had done nothing to stop it.

The terror of Uchiha Madara's strength was beyond comprehension.

Even with the Mangekyō Sharingan awakened, the chances of defeating him were slim to none.

While Itachi wallowed in grief, Madara stood a short distance away, arms crossed and an amused smirk plastered on his face.

He seemed to revel in the agony of breaking his opponent's spirit.

To take pleasure in an enemy's suffering… That's the battlefield's true rose.

Staring at Shisui's lifeless body on the ground, Itachi murmured,

"Shisui, I might not be able to avenge you after all… Hm?!"

Just as he was consumed by despair, Itachi noticed Shisui squinting, sneaking a quick glance at him.

Itachi: "???"

If not for his Mangekyō, he would have doubted his own eyes.

"…Shisui?"

Internally panicking, Shisui forced his eyes open with great effort and, in a "weakened" tone, said:

"Itachi, you… must live well… I… am about to die… Aaaah!"

With a dramatic scream, Shisui shut his eyes once more.

Itachi felt completely baffled. Something didn't add up…

"Pffft—hahaha!"

The previously stoic Madara burst into laughter, unable to hold it in any longer.

"…"

Itachi glanced at Madara, who was clutching his stomach, laughing uncontrollably, then back at the "dead" Shisui, whose body was trembling ever so slightly.

"…Shisui, get up." Itachi's voice was calm but tinged with irritation.

I'm dead, I'm dead…

Shisui kept his eyes closed, continuing to play dead.

"Get. Up!" Itachi snapped in a low, embarrassed tone.

"…Oh."

Shisui obediently rose to his feet, offering a sheepish smile as he noticed the Mangekyō spinning in Itachi's eyes.

"Hehe, looks like I got found out, huh…"

Turning to Madara—or rather, Obito—he complained,

"It's all your fault, Obito, laughing like that!"

"…My fault?"

Obito pointed at himself in disbelief.

"You're the one who blew your own cover first, Shisui!"

Itachi's frosty gaze turned to the pair.

"You two… better give me a good explanation."

Feeling the chill from Itachi's glare, both of them felt their necks stiffen.

Simultaneously, they pointed fingers at each other, blurting out,

"It was his idea!"

Obito: "…"

Shisui: "…"

After a long interrogation, Itachi finally pieced together the story.

Madara had indeed been revived, and the entire ninja world could soon be thrown into chaos.

Thus, the two "brothers" devised a plan to stage an act, using Madara's revival as the backdrop, to push Itachi into awakening his Mangekyō Sharingan and strengthening his resolve.

Their motive? Officially, it was to help Itachi grow stronger.

Unofficially, Itachi suspected they simply found it amusing.

Shisui offered a more detailed explanation:

"Under the influence of my Betsugan Kami, you focused entirely on the enemy in front of you, subconsciously ignoring other details."

Itachi's expression turned contemplative.

No wonder something had felt off, but he never stopped to analyze it.

For instance, how had Shisui escaped from someone as powerful as Madara?

Or why had Shisui summoned him out of Konoha instead of directly delivering the intel?

Everything had been deliberately orchestrated.

"If it were any other time, I would've caught on to those anomalies," Itachi thought.

Obito chimed in,

"If not for Betsugan Kami, my disguise wouldn't have fooled you for a second."

He grinned, adding,

"By the way, how was my acting? Pretty convincing, right?"

Shisui interjected eagerly,

"And mine? Mine was great too, wasn't it?"

Itachi let out a cold snort.

"I understand your intentions were for my benefit… but I hope such antics won't happen again."

Both of them mumbled apologetically,

"It won't, it won't…"

Itachi nodded, his gaze shifting to Shisui's profusely bleeding wound.

"Shisui… your injury…"

Shisui glanced at the gaping wound in his torso and waved dismissively.

"We made it realistic, that's all. Don't worry about it."

Itachi was stunned.

"…Are you sure? You've lost almost a basin of blood. Don't push yourself too far!"

Obito coughed twice before explaining,

"Shisui isn't in danger because of the Hashirama Cells."

"Hashirama Cells?" Itachi echoed, puzzled.

Obito elaborated,

"They're cells harvested from the First Hokage. Once implanted, they enhance the body, improving vitality, energy… and other perks."

Pulling out a scroll, Obito continued,

"Recently, I acquired a batch of Hashirama Cells. You two can split them."

With a sly grin, he added,

"Since Shisui already got stabbed, we don't need to make another cut."

Shisui froze.

"Obito… You didn't plan that stab ahead of time, did you?"

Obito slung an arm over Shisui's shoulders with a chuckle.

"Of course I did. You're my precious cousin—who else would I take care of like this?"

Shisui gave a hollow laugh.

"Sure, Obito, you're just full of love for me."

"Naturally," Obito smirked, unfurling the scroll.

As the seal was undone, a white, viscous substance appeared.

Obito scooped up some and slathered it on Shisui's wound.

The white tendrils writhed and swiftly closed the injury.

"And the rest goes to Itachi," Obito announced.

Itachi hesitated, eyeing the white mass.

"How… do I…?"

"Don't worry," Obito reassured.

"We'll handle it for you."

Obito stripped off Itachi's shirt, while Shisui pulled out a kunai, swiftly making a small incision.

Itachi winced, inhaling sharply.

If not for his trust in the two, he would've doubted their intentions.

"Shisui, here." Obito passed him a lump of Hashirama Cells.

Shisui pressed the cells onto Itachi's wound, watching as the white substance merged seamlessly with his flesh.

"Remarkable," Shisui noted.

"Itachi's body isn't rejecting the cells at all—they're integrating perfectly."

Obito nodded, patting Itachi on the shoulder.

"Now that you've awakened the Mangekyō, remember this: using its abilities strains your body significantly. The Hashirama Cells can mitigate that, but only to a certain extent. Understand?"

Itachi nodded solemnly.

"I understand."
