Staring closely at the blood-red eyeball placed in the bowl, Uchiha Kirin noticed that the three tomoe within had become extremely blurred. In their place, however, an unusual black ring had appeared—evidence of a transition state where the three-tomoe Sharingan was fading and the Mangekyō pattern was beginning to emerge.
"So this is what a half-step Mangekyō Sharingan looks like?"
Eyes lighting up with excitement, Kirin activated his own Sharingan to study the gem-like eye.
Even though this Sharingan had been frozen by the mysterious power of the system space—just like how invisible dojutsu power had been frozen before—he could still sense the eye's strange and soul-stirring energy through the stasis.
For a brief moment, a twisted thought entered Kirin's mind—what if he undid the system's freeze and transplanted the eye into his own body?
Luckily, he didn't possess the Yang Release affinity, had no knowledge of medical ninjutsu, and was completely clueless when it came to sealing techniques. If he recklessly lifted the system's freeze, the Sharingan would simply rot in the open air…
Still, Kirin couldn't suppress his curiosity. Just what kind of dojutsu lay hidden within this eye? Judging from Uchiha Setsuna's performance, it seemed to be related to healing—but this "healing" appeared to come at the cost of the user's own physical health...
He placed the eye back into the system space and lightly brushed it with his consciousness. A Trait entry popped up, displaying the eye's basic information:
『Uchiha Setsuna's Left Eye』
『Dojutsu Power: Between Three-Tomoe Sharingan and Mangekyō Sharingan』
『Contains Dojutsu: Butōgyokumei — A technique that seals the exact moment damage is inflicted, at the cost of a significant portion of the user's lifespan! (Dojutsu Status: Extremely Unstable)』
『A Noble Time-Based Dojutsu: The culmination of Uchiha Setsuna's lifetime of experience studying sealing techniques, fused with his unwavering will to protect the Uchiha』
『Due to the user's body being completely exhausted and their lifespan depleted, the dojutsu was never fully awakened』
"Hissss~"
Reading that, Uchiha Kirin couldn't help but suck in a sharp breath.
Sealing the moment of injury?!
As expected of a time-based dojutsu—it could seal the very moment an injury occurred. Wasn't that basically the same as deleting time?
And not just for his own injuries—it could even seal the injuries of others, making them appear fully healed in an instant. Even old wounds and severed limbs could be restored! In other words, this dojutsu could erase the past.
Kirin instantly thought of a comparison: "Izanagi" couldn't be stacked, and once used, it indiscriminately consumed dojutsu power to erase unfavorable outcomes.
But "Butōgyokumei" deleted the damage after it happened. As long as the user remained alive, they could instantly revive at full health. In fact, they could even seal the moment they used Izanagi!
Infinite Izanagi—who could possibly stand against that?!
"The only downside is the lifespan cost... and Mangekyō dojutsu power can't regenerate either, so you probably couldn't use it more than a few times..."
Kirin gently ran his fingers over the sealing scroll in his hand. This dojutsu had roots in sealing techniques—it could even seal time itself! No wonder Uchiha Setsuna had believed his story about time travel during the simulation. Not only that, he had encouraged Kirin to study sealing techniques and entrusted the Sharingan to him.
Kirin was already salivating over the potential of this time-based Mangekyō. He was itching to transplant the eye into himself immediately. But he knew full well that it would require a combination of sealing and medical ninjutsu.
"Sealing techniques... always sealing techniques. But where the hell am I supposed to learn them?"
When it came to sealing, Kirin was severely lacking. Sure, he had the strength to kill a Chūnin, but he couldn't even perform the most basic action of unsealing a scroll. As for sealing-related runes, the only one he could think of was the attraction sigil used in the Substitution Jutsu…
With such a weak foundation, figuring out sealing techniques on his own was pure fantasy.
While sealing could allow the weak to defeat the strong, the Uchiha clan wasn't known for it. And in Konoha, the powerful clans who once mastered sealing had either died out or faded into obscurity.
After the demise of the Uzumaki clan, their vast sealing legacy had likely been reclaimed by the Hokage's forces. These days, sealing techniques were basically monopolized by the ANBU and Root divisions.
There's no way he could just walk up and hand himself over to them...
"Wait a second—Uchiha Setsuna himself studied sealing. Why not just go to him directly?!"
Uchiha Setsuna had been around since Konoha's early days. Although he only awakened the Mangekyō during his confrontation with Kakuzu in the simulation, he was a true relic of the past—a man who had witnessed the era of Madara Uchiha.
He'd dedicated his life to studying the Sharingan and sealing techniques. In terms of experience, understanding of sealing, and insight into the Mangekyō, there was no doubt he vastly outclassed ordinary ninja.
Now that he'd made up his mind to find a teacher, Kirin began checking the items in the system space that were related to sealing:
First, there was the box he'd snatched from that barrier-type ninja. Then the large sealing scroll he'd commissioned from Boss Black Cat. And finally, the most important item of all—Setsuna's left eye, which could serve as a token of sincerity. Setsuna would undoubtedly recognize his own eye by its dojutsu signature!
"Wait! Amaterasu's Black Flames!"
He glanced again at the sealing scroll.
Amaterasu flames... paired with a sealing scroll... and suddenly, Kirin remembered a moment from the original series: when Jiraiya fought Uchiha Itachi. At that time, Jiraiya had used a jutsu called Fire Sealing Method to absorb the black flames of Amaterasu into a sealing scroll!
If the flames could be absorbed, then surely they could also be released!
Of course, Jiraiya was a top-tier Kage-level ninja. For him, releasing black flames wasn't worth the trouble—his Sage Art Fire Release was far more efficient.
But Kirin wasn't Kage-level. If he could seal those flames and then unleash them... he could probably one-shot multiple Jōnin—and maybe, just maybe, even have a shot at killing a Kage!
He looked again at the scroll—Fire Sealing Method, a ninjutsu capable of sealing flames. Even though the Uchiha weren't known for sealing, they were the fire-style specialists. It'd be weird if they didn't have something like this.
"System, what would happen if I take the Mangekyō Sharingan out and bring it into the simulation?"
Since he intended to bring Uchiha Setsuna's left eye with him, Kirin decided to check with the system just to be safe.
『Ding~ Bringing a human organ into the simulation will automatically lift the freeze placed by system space.』
『The organ will begin to naturally decay.』
『It is recommended that the host study sealing techniques and perform sealing in a sterile environment to preserve the Sharingan.』
"Whew—so long as I can take it in, that's enough!"
