Throne Of The Uchiha

Ability

After leaving the hospital, Fugaku made his way directly to the outskirts of Konoha. Despite having awakened the Mangekyō Sharingan, he had never once used it.

He had some initial insight into his abilities upon awakening, as Mangekyō techniques imprint themselves instinctively into the user's consciousness, but assumptions meant nothing without field testing.

Konoha was too densely populated, and there were too many potential observers. The Third Hokage's crystal ball technique—though limited in range—could still be used at any time to monitor suspicious activities. Should word of his Mangekyō reach the higher-ups, it would undoubtedly provoke fear, suspicion, or even greed. After all, this was the legendary Mangekyō Sharingan—an ocular power so rare that few in the Uchiha clan had ever awakened it.

Deep within the forest beyond Konoha's walls, Fugaku stood silently, eyes closed. When they opened, the three-tomoe Sharingan spun slowly. Then, with a pulse of chakra, the tomoe twisted and changed. The scarlet eyes reshaped into the intricate pinwheel pattern of the Mangekyō Sharingan.

Immediately, his field of vision transformed.

Compared to the three-tomoe form, the world through the Mangekyō was sharper, with every motion and fluctuation in chakra threads around him laid bare. Even the ambient shifts in wind and sound seemed more vivid, clearer, alive.

A surge of violent chakra welled up from within his eyes.

It was an overwhelming power—terrifying in scope. Fugaku instinctively understood its potential. But even as that intoxicating thought of invincibility crept in, he suppressed it instantly.

That arrogance—the belief in one's own supremacy after gaining power—was what led many Uchiha down a dark path. Every evolution of the Sharingan brought a qualitative leap in strength, but without emotional discipline and foresight, it bred hubris.

Fugaku had long tempered his heart against such delusions. He knew full well that the next Great Ninja War was on the horizon. In such a chaotic world, even the Mangekyō Sharingan would not make him invincible—only a step ahead of the average shinobi.

As for the exact nature of his Mangekyō abilities, he had only a vague understanding. One eye seemed attuned to offense, the other to stealth or utility.

Fugaku activated his left Mangekyō.

The pinwheel spun.

With a sudden burst, black flames erupted on the earth ahead. They ignited at the exact point where his gaze had focused. The inferno burned silently—unnatural and relentless.

He exhaled and cut off the chakra to his eye. The flames began to die down, but slowly. Blood trickled from the corner of his left eye.

Amaterasu.

The inextinguishable black flames. Itachi Uchiha would one day use the same technique, as would Sasuke. In the known Uchiha history, only a few had awakened Amaterasu. Fugaku now understood that its emergence was tied to both emotional trauma and inherited chakra predispositions—perhaps even genetic memory.

Though each Mangekyō was shaped by the user's heart and experiences, Fugaku suspected there was something inherent in his bloodline that favored Amaterasu. It couldn't be coincidence that others related to him had awakened similar flames.

Next, he activated his right eye.

A swirl of dark chakra gathered around him, and in an instant, black mist enveloped his form. His body gradually faded into transparency—until he was completely gone.

Yet Fugaku was still there, hidden in plain sight.

Unlike the Transparent Escape Technique used by Gekkō Hayate's father—an advanced sensory-blocking genjutsu—or Obito's Kamui which warped his body to another dimension, this ability rendered him visually undetectable but still present in the physical world. The black mist wasn't gone; it had merely become transparent. It cloaked his chakra, body, and scent to an extraordinary degree.

Five minutes passed. The mist dissipated, and Fugaku reappeared.

This ability was no phasing jutsu—it didn't make him intangible like Kamui. If someone could pinpoint his location through other means—such as sensory perception or the Byakugan—they could still strike him. However, he could also strike while cloaked, making it a deadly infiltration or assassination tool.

It was a double-edged blade, limited in duration and fueled by his chakra reserves. Fugaku hypothesized this ability stemmed from a mixture of subconscious envy for advanced concealment techniques and a deep-seated desire to move unseen, plotting in the shadows to protect his clan from behind the scenes.

He closed his eyes again and activated both Mangekyō at once.

A surge of Yin chakra rushed forth from deep within his body, and a skeletal form began to manifest around him. Chakra shaped itself into an ethereal black ribcage, then a spine, arms, and skull. Finally, it formed a towering humanoid upper body—a partial Susanoo.

Unlike Sasuke's or Itachi's versions, Fugaku's Susanoo was darker, shadowy, and less ethereal. Its aura was cold and oppressive, as though darkness itself had taken shape.

In its left hand formed a massive magatama-shaped orb. When launched, it exploded in a blast of destructive chakra, creating a crater in the ground ahead.

In the right hand, it held a massive sword—simple, sharp, and devastating in force. Unlike Itachi's Totsuka Blade, it carried no sealing properties. It was a purely physical construct—like Madara's first-stage Susanoo.

Two streams of blood ran down from Fugaku's eyes. The power drain was intense—chakra, stamina, and pupil force all vanishing at an alarming rate. Worse, he knew that this damage wasn't temporary. Each use of Mangekyō consumed vision permanently unless counteracted.

A Mangekyō without a replenishment method was doomed. The longer one used it, the closer one came to blindness.

But Fugaku was not panicking. He had a plan.

There were ways to slow the decline—chakra control, eye-rest intervals, and even the potential of absorbing visual energy through rare means. He would not be reckless.

As the sun dipped low on the horizon, Fugaku burned away all remaining traces of his training. Flames consumed the ground, clearing all signs of Susanoo and Amaterasu alike. Any recon shinobi would only detect signs of high-level Fire Release practice.

He turned and walked back toward the village.

Shortly after reentering Konoha, an Anbu operative appeared silently before him.

"Uchiha Fugaku. The Hokage requests your presence tomorrow morning at 10 a.m. for a leadership briefing."

Fugaku nodded. "Understood. I'll be there."

The latest class of Academy students was set to graduate. Tomorrow's meeting would likely involve team assignments for the genin.

Among this year's graduates, the brightest stars were undoubtedly the twin sons of the Hyuga clan leader—Hiashi and Hizashi. Though identical in birth, the clan's ancient traditions had carved out two starkly different destinies: Hiashi, the heir, and Hizashi, born seconds later, bound to the cursed seal and a life of servitude.

Unlike the Hyuga, the Uchiha clan—while proud—judged its members based primarily on the strength of their Sharingan. There were no cursed seals, but also no leniency. A child of the clan leader without a Sharingan would still be deemed inferior.

In Konoha's eyes, blood mattered.

But in the Uchiha's, only power mattered more.
