Uchiha Izuna

"Madara, Izuna, our clan leader and Butsuma Senju killed each other. We don't have time to grieve. We must first figure out how to withdraw our army to our clan's territory."

In the Land of Fire, inside the main tent of a temporary camp on the Mount Kumogakure battlefield, a middle-aged man nearing forty spoke.

The man was named Uchiha Gakugyo. Apart from the clan leader, Tajima Uchiha, he was the Uchiha Clan's strongest fighter, and he also served as Tajima's deputy, the Vice Clan Leader.

Just two days ago, during the great battle between the Uchiha and Senju...

The two strongest clans of the Sengoku era had lost their leaders: Tajima Uchiha and Butsuma Senju had killed each other.

Now the two clans were camped only a few dozen miles apart, and another battle could break out at any moment.

Uchiha Gakugyo advocated an immediate retreat, bringing the entire force back to their clan's territory to recover.

"I'm afraid the Senju Clan won't just let us go."

Madara Uchiha, who was only a little over twenty, spoke coldly.

His words won the agreement of the other clan members:

"Young Clan Head Madara is right."

"Though both clan leaders are dead, our Uchiha are at a disadvantage."

"I also think the Senju won't pass up such a good opportunity."

"If we retreat, they'll surely pursue us with their entire force."

Although Tajima Uchiha and Butsuma Senju had killed each other in the battle two days ago, the Senju still had the upper hand in the overall war.

The Uchiha's greatest concern was that the Senju would pursue them with their full force as they retreated. If they were attacked from behind, they would be in trouble.

Madara glanced at his younger brother Izuna, who sat to his left and had remained silent, then asked, "Izuna, what do you think?"

Izuna was still reeling. He'd never imagined, no matter how much he'd considered it, that he would transmigrate into the world of Naruto.

And not just that—he'd landed in the Sengoku era, its most brutal age!

If he had to transmigrate, Izuna would have preferred Boruto Uzumaki's era, where people played video games for no reason and coasted through life.

But right now, he had no choice but to accept reality. He rubbed his temples and said, "It's already very late. Let's all get some rest tonight and discuss this first thing tomorrow morning."

The Uchiha leaders in the main tent couldn't help but stare. None of them had expected Izuna to give that answer.

"Uh... don't we lack the time?"

An elite Uchiha jonin said, "The Senju are probably preparing to attack us. We should make a decision as soon as possible."

But Madara suddenly spoke up. "No, Izuna has a point."

"I know Hashirama... I mean, Hashirama Senju. With Butsuma Senju dead, Senju Takeuma is there, but Hashirama's position in the Senju Clan is already pivotal."

Madara continued, "After the battle two days ago, both the Senju and the Uchiha are exhausted. If we fight now, casualties will be several times higher than usual. Given Hashirama's nature, he absolutely wouldn't choose to launch a surprise attack at a time like this."

"Tonight, we'll do as Izuna suggested and get a good night's rest. We'll discuss things tomorrow morning."

Seeing Madara give the order, everyone considered that he had a point and said no more. They left the main tent and returned to their own tents to rest.

Only after Madara and Izuna were alone in the main tent did Madara ask, "Izuna, is there something you wanted to discuss with me in private?"

Izuna couldn't help but feel a headache coming on. I've only just transmigrated here and need time to sort out my thoughts. How did you decide I wanted to talk in private?

But since Madara had asked, Izuna chose a topic that made sense. "Big brother, have you awakened it too? That power."

During the meeting, Izuna had quietly sensed the power within his body.

He discovered that he had awakened the Uchiha Clan's strongest power: the Mangekyō Sharingan.

In the original story, Obito Uchiha had tricked Sasuke Uchiha by claiming that Madara and Izuna had each killed their best friend to obtain it.

But in reality, Madara and Izuna must have awakened it by witnessing their father Tajima Uchiha's death, just as Obito Uchiha and Kakashi had awakened theirs after witnessing Rin's death.

Madara's expression shifted. "Izuna, are you saying you've awakened it too?"

Izuna closed his eyes, then opened them a moment later. The Three Tomoe in his eyes spun into a shape like the Chinese character for "person."

Madara also closed his eyes. When he opened them, his ordinary Three-Tomoe Sharingan had transformed into a special Sharingan with elongated, curved comma-like markings.

They both had the Mangekyō Sharingan!

"What exactly is this new Sharingan...?"

Madara covered his eyes, looking puzzled.

"My guess is that witnessing the death of someone dear to us caused the Three Tomoe to evolve further, awakening a new Sharingan: the Mangekyō Sharingan," Izuna said.

"Mangekyō Sharingan? You came up with that name? It certainly suits it."

Madara nodded thoughtfully.

"Let's spend tonight learning about the Mangekyō Sharingan. Tomorrow, we can discuss how to deal with the Senju pursuit," Izuna suggested.

Madara thought for a moment, then nodded. The two of them returned to their respective tents.
