As an Uchiha I became the Jinchuriki of Senju Tobirama

Uchiha District.

Kazuki's Home.

The moment Tsunade knocked on the door and entered, she was greeted by a warm, collective welcome from everyone inside.

Sakumo and Kakuzu exchanged a glance—then the two troublemakers whistled mischievously, instantly making the atmosphere even livelier.

"Perhaps this is what youth is all about, Kakuzu," Sakumo said, patting his partner's shoulder with a sigh of sentiment. "It reminds me of the day I first fell in love..."

Off to the side, Kakashi frowned as he shot his father a disgruntled look.

Fell in love?

Was he talking about Kakashi's mother—Sakumo's wife—or some unknown first love from his youth?

Still, despite himself, the corners of Kakashi's mouth lifted beneath his mask, and he couldn't help but smile happily.

Everyone was genuinely pleased to see Tsunade and Kazuki together.

Both politically and emotionally, they were a perfect match.

Bathed in everyone's warm gazes, and under the teasing of Kakuzu and Sakumo, Tsunade's face gradually turned scarlet.

Oh, for heaven's sake!

Tsunade had thought she'd been doing a good job hiding her feelings for Kazuki—that no one could possibly tell.

But now, it was clear:

Everyone knew.

After the playful banter, the atmosphere grew even livelier.

And Tsunade, who had long considered Kazuki's home her own, quickly shed the last traces of unfamiliarity.

With natural authority, she began directing the group of rowdy men, organizing the surprise preparations for Kazuki's birthday in finer detail.

And just as they finished the final touches...

The one responsible for sensing Kazuki's chakra, Shisui, suddenly brightened up and shouted excitedly, "Big Brother's back!"

Everyone's hearts lifted with joy. They quickly turned off the lights and grabbed colorful party poppers.

Tsunade, meanwhile, picked up the giant cake, her heart brimming with happiness as she waited for Kazuki to return home—ready to feed him the first bite of cake and place a birthday hat on his head...

In the midst of complete darkness, under everyone's eager anticipation, a gentle knock sounded at the door.

As Shisui opened the door—

[Pop! Pop! Pop!]

Colorful confetti burst into the air from the party poppers. Holding the cake, a faint blush coloring her cheeks, Tsunade stepped forward. She gazed at the figure in the darkness—a man with white hair and crimson eyes—and softly said: "Happy birthday, Kazuki!"

Following Tsunade's words, everyone happily shouted, "Kazuki, happy birthday!"

At that moment, the lights came on.

The vibrant confetti sparkled brilliantly under the bright lights, and each person held the gifts they had prepared for Kazuki, smiling warmly.

But the moment the lights turned on, that heartwarming scene came to an abrupt halt.

Because standing at the door was not Kazuki—but another renowned ninja from Konohagakure: Senju Tobirama!

Everyone froze.

How was Senju Tobirama alive?!

Why was the Second Hokage standing here—with a pair of Sharingan that looked almost identical to Kazuki's, radiating that pure, familiar ocular power?

No one knew...

Senju Tobirama hadn't intended to make such a dramatic entrance. However, having just been revived, he still needed time to adjust to the power Kazuki had granted him. He couldn't yet deactivate the Sharingan smoothly; it would take a while to fully stabilize.

At least, that was how Senju Tobirama saw it.

Of course, it was also possible that Kazuki had deliberately left the Sharingan active—but Senju Tobirama would never even consider such a thing about the best Fourth Hokage in the world...

There were many rumors circulating in Konoha about Kazuki, Senju Tobirama, and the reincarnation of Uchiha Izuna.

The most credible ones stemmed from the Forbidden Techniques Creation Theory, attributed to Uzumaki Mito.

After receiving Uzumaki Mito's endorsement, Tsunade had occasionally shared snippets of information with others. As a result, most people accepted this theory and believed—just as the strongest sealing specialist had said—

"Senju Tobirama won't affect Kazuki. When the time comes, he can simply be removed."

But... reality seemed a little different.

Senju Tobirama had actually been revived—and the power surging in his eyes was the very same ocular power everyone had grown so familiar with through Kazuki!

In an instant, the joyous comedy turned into a tragic scene, all thanks to a certain unnamed Second Hokage.

Tsunade, still holding the cake, stared blankly at her great-uncle's face, a mixture of shock and fear swirling within her...

Could it be that Uzumaki Mito had been wrong, and Senju Tobirama had seized Kazuki's body?

Or worse yet—was it possible that Uzumaki Mito and Senju Tobirama had been colluding all along, tricking everyone merely to keep the situation stable?

An oppressive silence filled the room.

Brilliant confetti drifted down onto everyone's heads, shimmering under the lights like twinkling crystals...

But still, no one spoke.

No one dared to—fearful that even starting a conversation might confirm the worst nightmare descending upon Kazuki's home.

Hiruzen looked at the birthday party prepared for Kazuki, and a wave of blood surged to his head.

Just look...

Look carefully, my respected sensei, my dear Second Hokage Tobirama-sama!

Look at what you've done!

You've destroyed the most beautiful thing in this world!

Senju Tobirama gazed at the scene before him, and deep sorrow welled up in his eyes.

Kazuki, who should have been here to enjoy this beautiful moment, was instead locked in a life-and-death struggle with the Sage of Six Paths inside the Black Water Nine-Dragon Coffin...

Was Kazuki alright?

Kazuki had already sacrificed so, so much for Konoha—for the entire shinobi world!

If the facts were to be trusted, Kazuki was still doing relatively well...

Although he had just fought an intense battle with Kaguya, he had successfully beaten the Ancestor of Chakra into tears. With his fists, he not only managed to correct part of Kaguya's personality but also caused her children to drop precious 'gold coins', greatly refining his own bloodline in the process.

Just as Senju Tobirama was about to speak—coldly and pragmatically intending to interrupt the gathering and explain the situation to everyone—

Hiruzen suddenly lunged from behind Tobirama, shouting sharply, "Tobirama-sensei has taken over Kazuki's body!"

"Everyone don't hesitate! Attack together! If we move now, there might still be a chance to save Kazuki!"

Upon hearing Hiruzen's outcry, Senju Tobirama was utterly stunned.

What the hell was going on in this monkey's head?

How could this monkey think that he intended to take over Kazuki's body?

Tobirama truly couldn't understand...

Even if Tsunade had misunderstood him, Tobirama could have accepted it—after all, there was a gap in information between them.

But he was confident that he could explain things clearly to Tsunade and prevent the misunderstanding from escalating into internal conflict.

Hiruzen, however, had no excuse!

During the time when he had punished Shimura Danzō, Tobirama had temporarily taken over Kazuki's body and met him in the spiritual realm through genjutsu.

Tobirama believed he had made everything clear at the time…

Where exactly had the misunderstanding occurred for Hiruzen to end up thinking this way?

The first to react was Tsunade, who was still holding the cake.

In that instant, the shy blush on Tsunade's face—born from anticipation at seeing Kazuki—flared into a furious, blood-red anger. The veins at her temples bulged, making her look like a berserk Ōtsutsuki Kaguya, a lioness ready to devour her prey!

[Splat!]

Tsunade used the cake she was holding as her most convenient weapon. Empowered by her monstrous strength, she smashed it straight onto Senju Tobirama's face!

The cake exploded like a bomb!

Cream and frosting splattered everywhere, and the violent impact left Tobirama dizzy.

Seriously?! Just because the monkey said something, Tsunade believed it without question?!

Did he have no prestige or credibility left in this village? Why did everyone seem so ready to believe he would actually steal Kazuki's body...

If this misunderstanding were about anything else...

Maybe the people of Konoha would give Tobirama, their distinguished Second Hokage, a fair judgment. But when it came to anything related to the Uchiha...

Well, that was a different story.

Taking advantage of the moment, Hiruzen grabbed Tobirama's arm tightly with one hand to prevent him from weaving hand signs.

With his other hand, he fiercely bit down on his own finger, tearing away a chunk of flesh with the sheer force of it.

He knew all too well that when fighting against his own sensei, every opportunity was precious—he couldn't afford to waste a single moment!

Pressing his bloodied hand to the ground, Hiruzen roared: " Enma!"

With a swift movement, Enma extended his arms and instantly locked onto Tobirama's other arm.

However, upon realizing what was happening, Enma looked at Hiruzen, confusion written all over his face.

"Hiruzen," Enma asked blankly, "isn't this man I'm grabbing... the Second Hokage of Konohagakure, Senju Tobirama?"

"I thought he was dead?"

But no one answered Enma's question. After Hiruzen and Tsunade made their move, the others—though still a bit confused—largely understood that something must have gone terribly wrong with Kazuki!

Faced with the Second Hokage Senju Tobirama, all the shinobi of the Kazuki household rapidly began forming hand signs.
