Boom! Boom! Boom!!

The entire ground beneath their feet seemed to tremble fiercely. Under the manipulation of Uchiha Fugaku's Mangekyō Sharingan, three enormous fire dragons slammed down, engulfing the entire area where Yu stood in searing flames.

Boom!!

At the same time, the massive roaring water released by Yu earlier hit Uchiha Fugaku in mid-air. However, amidst the splashes of water, Uchiha Fugaku had already used Kami no Su to control a huge, solid cement wall, firmly blocking Yu's Water Release Ninjutsu attack.

"This isn't ordinary Water Release..."

Just as he managed to fend off the enormous water dragon attacking from above, Uchiha Fugaku sensed something amiss. His expression changed abruptly. "It's a Combination Jutsu! This kid actually mixed Lightning Release within the Water Release!"

Indeed, within the massive water dragon, a violent explosion of lightning erupted, and its immense power finally shattered the huge, solid cement wall in front of Uchiha Fugaku. Caught off guard, Uchiha Fugaku was grazed by the Lightning Water Dragon Bullet and when he fell to the ground, his body was already tingling with paralysis.

'Such formidable Ninjutsu...'

'But regardless... that kid must have suffered quite a bit, right?'

After landing, without caring about his arm completely paralyzed by lightning, Uchiha Fugaku's Mangekyo Sharingan locked firmly onto the ground completely engulfed by flames. With the boy's strength, he was fully justified in being so vigilant.

"So, being able to freely manipulate the form of flames like this..."

"Is the awakened ability of the other Mangekyo Sharingan Kagutsuchi?"

Sure enough, before Uchiha Fugaku could even relax his tense body, the searing flames before him gradually dissipated, and from within, came Yu's calm and indifferent voice.

Barrier Sphere!!

A massive and transparent barrier formed into a sphere, completely enveloping both Yu and Michael within it. The ground around their feet was all scorched into charcoal by Uchiha Fugaku's Fire Release Ninjutsu, but under the protection of the Barrier Sphere, Yu emerged unscathed.

In fact, if Yu wanted to resort to a rogue tactic, he could have Michael envelop him in the Barrier Sphere and then use Parasitic Threads Manipulation Devil Puppet to fight from the outside.

However, up to this point, among all the opponents Yu has faced, none have possessed the strength to force him to employ such a rogue tactic.

"Fire Release is completely ineffective..."

"Besides the Magnet Release Kekkei Genkai, does his Puppetry also possess absolute defensive capabilities?"

Watching Yu reappear unscathed under Michael's protection, Uchiha Fugaku's Mangekyo Sharingan's pupils slightly contracted, rapidly analyzing the information before him. "And the Mangekyo Sharingan and Kagutsuchi..."

A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

"This kid, where did he get all this information from? Could it be Shisui..."

"No, it's impossible... Even if it were Shisui, he couldn't possibly fully understand all the secrets of the Mangekyo Sharingan..."

The Mangekyo Sharingan is a secret known to very few within the entire Uchiha Clan, yet the present Yu displays a mastery of the Mangekyo Sharingan's abilities as if it were common knowledge. Uchiha Fugaku couldn't help but begin to doubt in his heart.

"Kagutsuchi... how interesting."

"It seems that the abilities awakened by the father and son trio's Mangekyo Sharingan still have astonishing similarities."

With the right eye controlling objects through Kami no Su, and the left eye manipulating the form of flames through Kagutsuchi, after confirming the abilities of Uchiha Fugaku's Mangekyo Sharingan before him, Yu's piercing gaze became somewhat intriguing.

Kagutsuchi - a deity in mythology who controls all flames, also a Dojutsu residing in the Mangekyo Sharingan of Uchiha Sasuke's right eye in the anime, capable of controlling the form of flames.

One can freely shape flames into shields, blades, arrows, Senbon, Tomoe, fireballs, or any other form, significantly increasing the lethality of the flames. Additionally, one can also attach flames to ninja tools and Ninjutsu during combat.

For those familiar with Naruto, they should know that the Mangekyo Sharingan know that the power of the Mangekyo Sharingan is generated by both bloodline and inner strength.

Only when one witnesses the death of a close person firsthand, experiencing extremely intense negative mental stimuli, can a member of the Uchiha Clan potentially unlock the Mangekyo Sharingan. At the moment of awakening, the strongest desire deep within the heart of the awakener will be called forth, thus resulting in various unique abilities.

For example, Uchiha Itachi, in the anime, unlocked his Mangekyo Sharingan after witnessing the death of his dear friend Shisui. At that time, the relationship between the Uchiha and Konoha was on the brink of collapse, almost reaching a critical point. Itachi was torn apart inside; he wanted to stop everything, and to stop it, he needed immense power.

So, the "Strongest Attack," Amaterasu, was born, but he understood deep down that it would be difficult to save the Uchiha solely with his own abilities. He wanted to change both sides. Consequently, Tsukuyomi, which corresponds to "everything controlled by the user of the jutsu," appeared in his left eye.

For example, Uchiha Sasuke, in the anime, awakened his eyes when he just learned the truth about Itachi, filled with regret and anger. He desired revenge, yet also yearned to control his own destiny.

Accordingly, revenge requires power. Thus, his left eye obtained Amaterasu, the "Strongest Physical Attack," while his right eye, in order to save Karin, who was burned by Amaterasu, awakened Kagutsuchi, capable of "freely controlling this power."

Similarly, Obito, when he witnessed Kakashi killing Rin with his own eyes, collapsed deep within. He resented this world and wanted to escape it. Hence, his left eye became Kamui, "tearing apart this world," and his right eye became intangibility, "escaping from this world."

As for the time when Shisui awakened his eyes, Yu cannot know for sure. However, given the circumstances of recent years, Shisui's innermost desire was likely to strongly prevent the Uchiha's rebellion. When conventional means became ineffective, he hoped to hypnotize and control everything himself. Therefore, he gained the ability of Kotoamatsukami, "able to manipulate enemies without their knowledge."

So, what was the wish of Uchiha Fugaku at the moment he awakened his eyes, having witnessed a friend sacrifice himself to save him during the Great Ninja War?

Was it Kami no Su, "manipulating everything around to destroy enemies"?

Or was it Kagutsuchi, "completely controlling this power"?

All of this, aside from the person in question, Uchiha Fugaku, remains unknown to others.

"Alright, this boring warm-up should come to an end."

Retracting his contemplative gaze, Yu sensed through Observation Haki that Shisui and Itachi's chakra were rapidly approaching. At this moment, Yu's calm and composed gaze finally began to turn serious.

"Shisui and Itachi should be arriving here soon. Before that happens, let's take care of you all!"
