This Dojutsu Doesn't Consume Eyes

In the dark, silent room, two scarlet points shone with exceptional brightness. A closer look revealed a pair of eyes with scarlet irises, divided into three sections by black, three-bladed shuriken that rotated counterclockwise into hooked shapes, resembling windmills. Yes, these were Minagawa Uchiha's Mangekyō Sharingan.

The windmill-like Mangekyō Sharingan slowly rotated, adding an air of mystery to his already handsome face.

Suddenly, a faint smile appeared on Minagawa Uchiha's contemplative face, soon turning into hearty laughter.

"Hahaha! Just as expected. Truly worthy of the Mirror of the Heart. Compared to Uchiha Itachi's Amaterasu that couldn't even burn anyone to death, or Tsukuyomi that Sasuke could break with a mere cursed seal, this is what you call a dojutsu."

Having received the information conveyed by his Mangekyō Sharingan, Minagawa Uchiha could not help laughing aloud, even though he had long anticipated what his dojutsu would be.

This pride completely released all the pressure and frustration he had accumulated over the past six months since awakening his memories. He had every right to be proud. Rather than crushing him, that pressure had forged his obsession and awakened this immensely powerful Mangekyō Sharingan with limitless potential.

After determining the abilities his Mangekyō Sharingan would awaken, Minagawa Uchiha had been preparing for this very moment.

Unlike other Uchiha who awakened the Mangekyō Sharingan after suffering a blow so severe that they were left dazed and muddled, allowing the Mangekyō Sharingan to extract only their vague wishes at the time—

When Minagawa Uchiha awakened his Mangekyō Sharingan, he had already mixed a firm desire of the heart into those overwhelming negative emotions. The Mangekyō Sharingan directly extracted that desire and responded to it. And that response was certainly something the Mangekyō Sharingan could achieve.

Thus, Minagawa Uchiha got the dojutsu he had desired:

His left eye was called Izanagi and possessed the power of Materialization to Void.

In the Original Work, this was an Ultimate Dojutsu that required the consumption of at least a Three Tomoe Sharingan to perform. For the duration of the technique, it could turn any reality unfavorable to the user into a dream. At its greatest, it could even reverse life and death. This technique had shone brilliantly in the hands of Uchiha Madara and Obito Uchiha, changing the reality of their defeats. It allowed Uchiha Madara to plot for the Rinnegan and the Moon Eye Plan, while Obito Uchiha escaped from six hundred billion explosive tags.

Danzo had taken this technique even further. With Sharingan covering his entire arm, he treated the Three Tomoe Sharingan required by the technique as resurrection coins. Until the Sharingan on his arm had been exhausted, no one could kill him.

But as the dojutsu of Minagawa Uchiha's Mangekyō Sharingan, it had become a technique that required only Dojutsu Power, not the consumption of a Sharingan.

Minagawa Uchiha had actually guessed this before awakening it. When Uchiha Madara and Hashirama Senju fought at the Valley of the End, Madara had used Izanagi on himself. Judging by how Hashirama Senju had been beaten so badly that his lifespan was greatly reduced and he died not long after returning, Uchiha Madara must have used his own eyes then. Otherwise, in a battle of that intensity, he would not have had the chance to replace his eyes.

Yet Uchiha Madara later awakened the Rinnegan in both eyes. That meant that once one reached the Mangekyō Sharingan level, it might be possible to recover after using Izanagi. Whether that recovery simply required a long time or only occurred after evolving into the Rinnegan, at least such a possibility existed.

So Minagawa Uchiha did not hesitate. He directly chose this dojutsu and stopped considering Kamui.

His right eye, meanwhile, held Izanami, the counterpart to Izanagi, possessing the power of Materialization to Reality.

In the Original Work, this was likewise a dojutsu that required the consumption of a Sharingan. Once cast upon a target, the target could only escape after recognizing their true self—or, more precisely, after fulfilling the conditions stipulated by the caster.

Only Uchiha Itachi had been seen using this technique in the Original Work. He pulled Orochimaru's Kabuto into a looping dream and thoroughly changed his way of thinking. Only after Kabuto Yakushi found himself again did he escape the cycle.

Judging from that battle, compared with the famous Izanagi, Izanami seemed somewhat not worth the same price for the effect it achieved, making its reputation seem undeserved.

But in Minagawa Uchiha's view, perhaps Uchiha Itachi had felt that achieving that much was enough under those circumstances, which was why he had not displayed the terrifying aspect of this dojutsu. After all, according to Uchiha Itachi's own explanation, Izanami was an Ultimate Dojutsu capable of turning dreams into reality.

This also aligned with the principle of Yin Release: using spiritual control to create form from nothing, creating tangible shapes out of the formless. The Mangekyō Sharingan itself was an embodiment of Yin Release. As such an ultimate Yin Release dojutsu, it was entirely possible for it to achieve this.

Likewise, casting Izanami consumed Dojutsu Power in place of a Sharingan.

Either of these dojutsu alone was a bug-like ability, but in Minagawa Uchiha's eyes, they were far from the highest pursuit of this pair of Mangekyō Sharingan.

He valued these two abilities so highly because the Original Work had mentioned that only a pair of Mangekyō could unleash the true power of the Mangekyō Sharingan.

This information was demonstrated when Kakashi fought Kaguya Otsutsuki. Kakashi, who had originally only been making up the numbers, actually managed to force a stalemate after obtaining Obito Uchiha's dual Kamui.

From the difference in Obito Uchiha's performance before and after obtaining both Mangekyō, Minagawa Uchiha inferred that two Mangekyō with similar abilities could complement each other and thereby elevate into an even stronger power.

At its core, Obito Uchiha's Kamui merely granted him an exclusive Kamui Dimension, along with the ability to open and close that space. The intangibility, teleportation, and spatial distortion derived later were all applications built upon that foundation. Later, the two Kamui combined as one, integrating long-range and close-range use while amplifying both, reaching the point where they could cause trouble before Kaguya Otsutsuki and creating Kakashi's moment in the spotlight.

Therefore, inspired by how dual Kamui complemented each other and vastly strengthened the use of space, Minagawa Uchiha guessed that Izanagi and Izanami could certainly combine their original powers to form the path of the Interchange of Reality and Illusion.

Izanagi would no longer be limited to use on himself; it could also turn other things into dreams. Izanami would no longer merely turn thoughts into reality; it could also bring things from dreams into reality.

Naturally, the Dojutsu Power consumption would be considerable.

"Haha, it really succeeded! This is the correct way to use the Mangekyō Sharingan. Those people who awakened their eyes passively were simply wasting a treasure. Whether Kotoamatsukami, Tsukuyomi, or Amaterasu, they were all already-formed external add-ons that had basically lost their potential for growth."

"Only Obito Uchiha stumbled into a pair of complementary Mangekyō. Heh, perhaps it was not an accident after all. His Mangekyō Sharingan had awakened under Uchiha Madara's script. As Madara's representative, someone meant to help him carry out his plan, he must have received some guidance one way or another."
