Shinji's Mangekyo Dojutsu

From the astonishment in Shion's eyes, Shinji knew she had definitely witnessed his fierce battle with the Hand Demon.

In other words...

His Susanoo had been exposed. It would be difficult to keep the secret of his Mangekyō Sharingan hidden now.

Shion had no idea what was troubling Shinji. She looked him up and down, her eyes filled with admiration.

Should I silence her?

Shinji couldn't bring himself to decide.

Whoosh.

As if sensing the trace of killing intent Shinji had let slip, the little bell hanging from Shion's chest suddenly blazed with dazzling light.

"What is this...?"

Feeling threatened, Shinji took a step back.

Others might not know, but he knew the truth about the Land of Demons Miko.

The little bell hanging from Shion's chest was an exceptionally powerful magical artifact.

It seemed to protect Shion, but its true purpose was to seal her Miko powers, preventing young Shion from hurting the people around her by using them recklessly.

In short, that thing was a restraint disguised as a protective charm!

To kill Shion, he would first have to destroy the bell. But if he did, he would have to face the Land of Demons Miko with her powers unsealed.

Shinji abandoned the idea of silencing her.

It was true that Shion was a novice Miko, but then again, wasn't he a novice shinobi himself?

He couldn't be sure his Susanoo could withstand Shion's Sealing Technique. The Land of Demons Miko was capable of sealing monsters on the level of a Tailed Beast, after all.

But he obviously couldn't just leave things as they were.

So he thought of using genjutsu. Fixing his gaze on Shion, he activated his Mangekyō Sharingan and used his Dojutsu to implant a suggestion in her mind: You never saw me.

In an instant,

Shion's expression went blank. She repeated after Shinji in a daze: "Never saw you... Never saw you..."

"Did it work?"

Shinji watched her for a moment, then quietly breathed a sigh of relief.

Luckily, Shion's Miko powers were sealed, and she had spent very little time with him. Otherwise, with his half-baked Mangekyō Sharingan genjutsu, implanting that suggestion would have been difficult.

Even so, he didn't feel very confident about it.

If he ran into Shion again in the future, there was still a good chance she would remember what had happened.

Fortunately, Shion was the Land of Demons Miko and wouldn't leave the Land of Demons easily, so the odds of them meeting again anytime soon were low.

Just then, a patch of firelight appeared in the darkness in the distance. It seemed a large group of people were rushing toward the palace with torches, in a panic.

They were obviously guards from the Land of Demons, hurrying over from elsewhere as reinforcements.

Just as Shinji was wondering how he would get back to Konoha, whoosh—his figure vanished from where he stood.

Looking at the familiar room, Shinji realized he was back.

The clock on the wall showed that he had been gone for about thirty minutes.

That was just enough time for him to witness the Hand Demon slaughtering the guards and then kill it himself.

In other words, he had been transported instantly to the area where the Hand Demon had invaded—the palace of the Land of Demons Miko—and then transported back the moment the battle ended.

It was somewhat similar to the Flying Thunder God Technique.

"Ah!"

A sudden stabbing pain shot through both his eyes.

Enduring the pain, Shinji quickly deactivated his Mangekyō Sharingan, and his scarlet eyes quietly returned to their usual dark color.

It took a good while for the pain in his eyes to gradually subside.

Phew.

He exhaled heavily, his expression grim.

After successfully stopping the invasion and receiving the Shinobi World's blessing, the amount of Chakra in his body had indeed nearly doubled. But Chakra was one thing, and the Dojutsu of the Mangekyō Sharingan was another.

To put it simply,

Chakra was refined from physical and spiritual energy, and it could be replenished through rest.

It was renewable!

The Dojutsu of the Mangekyō Sharingan, on the other hand, was a highly refined form of Yin Release Chakra.

Its reserves had been fixed the moment the Mangekyō Sharingan awakened. The more he used, the less he had.

Until he could convert ordinary Chakra into high-quality Yin Release Chakra, the Dojutsu he used up couldn't be replenished.

"Activating Susanoo this time cost me too much. If I do this a few more times, my Mangekyō Sharingan will be ruined!"

Back when his life was in danger, he hadn't given it much thought before using Susanoo.

But the sharp pain in his eyes just now had made him experience firsthand the undeniable truth that the Mangekyō Sharingan was a consumable.

Resting a hand on his forehead, Shinji sat down on the bed.

The invaders in this attack on the Shinobi World had been demons from Demon Slayer, so there was a very good chance the next invaders would be demons too.

But he wasn't an expert at fighting demons!

He had used the clumsiest method possible to kill the Hand Demon just now.

After smashing the Hand Demon to pieces with Susanoo the first time, he had used the keen insight of his Mangekyō Sharingan to confirm that the Hand Demon was smaller after regenerating.

That led him to conclude that although demons could keep regenerating, they still needed to expend some kind of flesh-and-blood energy.

As long as he dealt the demon multiple devastating blows in a short period and it couldn't replenish its supply of flesh and blood, it would eventually lose the ability to regenerate from overexertion.

But that method worked on the bulky Hand Demon; it might not work on other demons.

If he encountered a fast, tactically skilled demon next time, it would be very difficult for Shinji to repeat this victory.

"I have to find a way to truly counter demons!"

Cutting off their heads with a Nichirin Blade was undoubtedly the simplest method, but Shinji wasn't sure whether the Shinobi World had the special ore needed to forge one.

He had never seen Wisteria in Konoha, either.

As for sunlight, demons obviously wouldn't invade the Shinobi World during the day.

"If demons are afraid of sunlight, would Amaterasu, the 'flames of the sun,' work on them?"

Shinji suddenly thought of Amaterasu, a Mangekyō Sharingan Dojutsu.

Amaterasu's Black Flame could burn anything and would never go out.

So even if it didn't have a special effect against demons like a Nichirin Blade, it could still cling to them and burn them to ashes in an endless blaze.

Unfortunately...

Shinji's Mangekyō Sharingan didn't have Amaterasu.

Whenever he thought about the Dojutsu his Mangekyō Sharingan had given him, he felt at a loss.

Both of his eyes had the same Dojutsu, called Susanoo Lamp.

As the name suggested, it was a Dojutsu built around Susanoo. To use Susanoo Lamp, he first had to activate Susanoo.

Unlike common ninjutsu-type or genjutsu-type Dojutsu like Amaterasu and Tsukuyomi, Susanoo Lamp was a relatively rare, utility-type Dojutsu.

When he activated Susanoo and Susanoo Lamp at the same time, a second pair of eye sockets would appear on the face of his Susanoo—a pair of empty sockets that could hold another set of eyes!

That's right!

Susanoo Lamp's ability was to let his Susanoo wield a second pair of eyes!

From a certain perspective, the creation of this Dojutsu might have been a reflection of the Sharingan's combined impression of its original owner and him, a transmigrator.

In Shinji's opinion, this Dojutsu was actually very powerful.

But he didn't have a second pair of eyes to wield, so for now, his Mangekyō Sharingan was a blank slate. Susanoo was the only Dojutsu he could use.

And compared with Mangekyō Dojutsu like Amaterasu and Tsukuyomi, which could be used with a single eye, Susanoo put a far greater strain on his body and consumed much more of his Dojutsu.

If he used Susanoo in every battle, he wouldn't last more than a few fights.

Shinji gathered his thoughts and considered how to solve the problem.

There were solutions.

The simplest and most direct option was to find the Mangekyō Sharingan of a close relative and evolve his own Mangekyō Sharingan into an Eternal Mangekyō Sharingan.

Failing that, he at least needed to get his hands on a second Mangekyō Sharingan that Susanoo Lamp could wield, giving him more Dojutsu to use.

Following that line of thought, he considered the Mangekyō Sharingan that currently existed in the Shinobi World. "Not counting mine, there should be four pairs of Mangekyō Sharingan in the Shinobi World right now..."

One of Obito's Mangekyō was in his own possession, and the other was with Kakashi.

One of Shisui's Mangekyō had been taken by Danzo, while Itachi kept the other.

Itachi's Mangekyō was in his own possession.

Those three pairs of Mangekyō were all held by powerful people. With Shinji's current strength, he couldn't even consider taking them.

The only pair he could think about getting was the Mangekyō Sharingan belonging to the late Uchiha Clan Head, Fugaku Uchiha.

The reason he thought he might be able to get them was that Fugaku had never revealed the secret of his Mangekyō Sharingan to anyone, not even before his death.

So although the village had confiscated Fugaku's eyes, it probably didn't know they were a pair of Mangekyō.

That meant those eyes wouldn't be guarded too heavily.

After all, Shinji had personally seen the Medical Team remove the Sharingan from the bodies of Uchiha clansmen and put them in preservation containers in the morgue that night.

With so many Sharingan collected at once, their value would inevitably be diminished.

Of the four pairs of Mangekyō in the Shinobi World, Fugaku's would therefore be the easiest to obtain—and the pair Shinji had the best chance of getting his hands on.

"But first, I have to find out where the village keeps the Sharingan."

Although he was in a hurry, Shinji knew he couldn't rush this. He had to plan carefully, because one mistake could leave him with neither the Mangekyō nor his own life.

Besides, improving his Taijutsu and ninjutsu as soon as possible was also an urgent priority.

As he thought, sleepiness slowly crept over him. Once the excitement of the battle wore off, exhaustion set in.
