Sasuke Was Dumbfounded—Teacher Kakashi Has a Mangekyo Sharingan?

Obito looked at the other party's Great Fireball Technique, which had taken six hand seals to cast, in confusion. He truly could not understand why the other party still wore such a mysteriously confident smile.

Great Fireball Technique.

This was a ninjutsu created by the Uchiha Clan, and one of the foundational techniques many ninja learned when studying Fire Release.

According to the history books, the Great Fireball Technique had originally required six hand seals.

"Snake—Ram—Monkey—Boar—Horse—Tiger." These were the six seals required for the Great Fireball Technique.

As one grew stronger and gained better control over the Chakra within one's body, some of the steps could be streamlined.

Especially after the Emperor had made broad changes to the Chakra system, even Genin now only needed four seals to use the Great Fireball Technique.

And he only needed two!

After all, this was merely a C-rank ninjutsu!

One had to know that combat was all about information gaps and speed gaps. If the other side could cast one technique in the same amount of time you could cast two, who else would win if not you?

Obito moved!

He pressed his palms together, interlocking all ten fingers.

"Snake!"

Next, the index and middle fingers of both hands straightened.

"Tiger!"

The next moment, surging power began gathering in his mouth.

Even with a huge ball of steaming flames already right before him, Obito remained utterly calm, as if Mount Tai could collapse before him without changing his expression.

Just as the flames were about to engulf him, Obito took a deep breath, and the Chakra within his body rapidly condensed.

His cheeks swelled as a massive mouthful of fire-nature Chakra erupted outward.

"Fire Release! Great Fireball Technique!"

The C-rank ninjutsu Obito used erupted like a raging volcano at that moment, overwhelmingly powerful!

The blazing flames of the Great Fireball Technique surged forward, instantly swallowing and covering Kakashi's fireball.

Compared to it, Kakashi's Great Fireball Technique was fairly powerful as well, but before Obito's, it seemed utterly outclassed.

The entire area was illuminated by the scorching flames. Even the surrounding air seemed to ignite, crackling loudly.

After overwhelming Kakashi's Great Fireball Technique, Obito's Great Fireball Technique charged straight at Kakashi without the slightest pause.

Kakashi's expression changed drastically. He could not believe that the other party had still managed to block it when the Great Fireball had already been right in front of him!

And it seemed like the other party had only formed two seals just now...

Was his taijutsu so strong, and his speed so fast, that Kakashi had failed to see clearly? No! There was no time to think!

"Earth Release—Earth Style Wall!"

Kakashi rapidly formed seals. A huge mass of yellow earth rose from the ground and formed a massive wall, especially the dog head on the wall looking particularly out of place.

Kakashi's lips twitched.

Why was there a dog-head sculpture on the Earth Style Wall? Was this showing off how refined his Chakra control was?

The Earth Style Wall was instantly covered by the Great Fireball. Just when Kakashi thought that would be the end of it, the flames actually burned cracks through the wall, faintly showing signs of bursting through again.

Just as Kakashi hesitated over whether to use Water Release to cool down the Earth Style Wall, Obito stopped his attack.

Kakashi inwardly let out a sigh of relief, but a deep sense of helplessness quickly rose in his heart.

The other side had used one Great Fireball, and he had nearly needed three techniques to block it?

No! It was only because that had been an Escapism Technique he was not skilled at!

Kakashi could only comfort himself to ease the fear in his heart.

Nearby, Naruto was still excited by the spectacular exchange just now, while Sasuke had already turned completely to stone.

Back during the Genin exam, when he had used the Great Fireball Technique against Teacher Kakashi, hadn't he needed more than twenty seals before he successfully cast it?

This person before him... had used only two?!

Even Itachi needed at least five, right?

Was he stronger than Itachi??

Kakashi knew he could not drag this out any longer. Chakra had always been one of his weaknesses. He had not felt it when using his short blade before, but now that they were clashing with ninjutsu, he naturally held no advantage whatsoever!

In that case...

Kakashi sighed, raised one hand, and straightened his forehead protector.

The next moment, the eye covered by a scar suddenly opened.

"I'll have to end this quickly!"

In an instant, the Three-Tomoe Sharingan opened!

"The Sharingan?!"

Three astonished voices rang out.

Obito opened his mouth wide in an exaggerated expression, looking at Kakashi and then at Kakashi again.

He could not understand why an Uchiha eye had appeared in this world's Kakashi, and why there was only one of them.

Kakashi himself was equally shocked. Every clan took its own Kekkei Genkai extremely seriously. This world's version of him had actually managed to get hold of a Sharingan?

Sasuke was equally stunned. Why was the eye of someone from his clan on Teacher Kakashi?

Obito glanced at Kakashi, who was rarely showing such a shocked expression, and teased, "Kakashi, look! The version of you in this world even got himself a Sharingan!"

"Hiss... Can this body of mine handle it?"

Thinking of how Obito had looked drained every time he used the Sharingan at first, like he had been sucked dry by a two-hundred-pound beauty, Kakashi shuddered.

Could the version of him in this world have some special physique?

Obito looked toward Kakashi, and the excitement that had just faded from his eyes surged forth again.

"If you have a Sharingan too..."

After all, he truly was slightly stronger than Kakashi when relying on the Sharingan, but to him, that was a humiliation. Yet if he did not open his eyes, he could not beat Kakashi; and if he did, any victory would be dishonorable.

Now that he could compete against a Kakashi with the Sharingan, he naturally had to go all out!

"Kakashi! Since you have a Sharingan too... then let's fight with everything we've got! Hahahaha!"

Obito revealed a wild Uchiha grin, and then both of his eyes began to change.

One-Tomoe... Two-Tomoe... Three-Tomoe!

He had mastered the use of his ocular power to perfection. Even the speed at which his eyes changed from black to the Sharingan was controlled with extreme precision.

But it was not over yet!

The Three-Tomoe spun rapidly before completely transforming into a Mangekyo Sharingan!

Watching the Three-Tomoe of this clansman before him transform into a pinwheel-like Mangekyo Sharingan, Sasuke was completely numb.

Wait!

Mangekyo Sharingan?!

Holy shit!

I only just awakened my Two-Tomoe!

And he could freely activate and deactivate the Mangekyo Sharingan?

As Uchiha Fugaku's son, shouldn't his bloodline be the purest?

Then why was he only at Two-Tomoe now? Was he really Fugaku's biological son?

Was this person's bloodline even purer than his?

While Sasuke was still racking his brains, trying to find clues from their everyday interactions in his memories to determine whether he was really Fugaku's biological son, he saw Teacher Kakashi's Three-Tomoe transform into a Mangekyo Sharingan almost identical to the other man's.

???

What the hell?!

Wasn't he the Uchiha Clan's only remaining seedling? Why had he encountered two people using the Sharingan in a single day??

And both were using the Mangekyo Sharingan from Uchiha legend?

As for why he was the only remaining seedling, it was because, in Sasuke's heart, Itachi had long ceased to deserve being called an Uchiha.

"Huh? He has a Mangekyo Sharingan too? Kakashi, I'm guessing this guy just looks like you. Maybe he isn't you at all."

"Since you have a Mangekyo Sharingan too, then I won't hold back!"

As Obito's words fell, a blue Susanoo fully unfolded in the next instant!
