Kamui

"Twelve Divine Maidens mission?"

Shin silently opened the system. At the top, under the mission tab, he saw the main mission: Become the final BOSS of this world and unite the entire world. Reward: Ownership of the Naruto World! Time limit: Until the end of the story. Mission failure: Death!

After the main mission, a line of slightly smaller text appeared: Side mission: Assemble the Twelve Divine Maidens. Unlock mission item: Divine Maiden Contract. Time limit: Same as the main mission. Mission failure: Death!

Beside the mission were some papers that looked like contracts stacked together. He silently counted them. There were exactly twelve.

"So these are the so-called Divine Maiden Contracts. But how do I take them out?"

At the thought, his hands suddenly grew heavy. A large stack of papers had appeared in them. They felt soft and supple. Though they looked like paper, they were entirely different, with remarkable toughness.

He held them up and took a look. The writing resembled tadpoles and looked somewhat like the markings he used for the Flying Thunder God Technique. He couldn't recognize any of it, yet somehow understood its meaning.

This contract was an extremely advanced master-servant contract that could only be used on women. Once a woman signed her name at the end of the contract, she automatically became the property of the contract's master. The master could order her to do anything, but the contract would not change her original state of mind.

For example, if a woman hated the contract's master deep down, she would still hate him after signing. However, she would be unable to disobey his orders, nor would she be able to do anything that harmed him.

Additional note: The contract only takes effect if the woman signs it of her own free will. The host is advised to make good use of this.

"Now that's a good thing."

Looking at the contract's description, Shin felt his heart itch with anticipation. If he could get the likes of Tsunade, Mei Terumi, and Hinata from the original story to sign them... The image was so beautiful he didn't dare imagine it.

"The only downside is that the woman has to sign voluntarily for it to take effect. What woman would willingly become a slave? That's a bit of a problem."

As he thought it over, Shin carefully put the contracts away. At the same time, he frowned and thought, It's such a hassle to carry these contracts around. It'd be a disaster if they were destroyed by an enemy's Fire Style during a fight. And when I use the Flying Thunder God, I have to carry around a lot of Kunai. I've stuck two small Ninja Tool Scrolls to my wrists, but their capacity is limited. There are only a little over a hundred Kunai in total. If I really go to war in the future, that might not be enough.

And carrying the Heaven Cloud Sword around every day is a pain, too. It'd be great to have a private space. As far as I can remember, the only character in the original story who explicitly had a space on hand was Obito Uchiha, with his Intangibility. I have enough points now, but I already have the Flying Thunder God, so I'm not in any rush to get Intangibility.

After thinking it over, he asked in his mind, "System, do you have anything like a space bag?"

After a brief silence, the system's emotionless voice rang out. "Mangekyo eye technique: Intangibility. Includes a personal space. Ninjutsu rank: S. Cost: 10,000 points. Requires the Mangekyo Sharingan to redeem. The host has the Three-Tomoe Sharingan. Can be forcibly redeemed for 5,000 points. Sufficient points. Redeem?"

"Don't redeem it!"

Shin hurriedly shouted in his mind. Are you kidding me? I worked so hard to go out and hunt down two Jonin for 10,000 points. If I spend them all on Intangibility now, I'll cry myself to sleep.

"Besides Intangibility, is there no other space I can carry around with me?" Shin still felt a little reluctant. Having a personal space would make many things much more convenient in the future.

"Scanning host. Ding... Flying Thunder God Technique detected. For 5,000 points, a personal space can be opened. Space capacity is related to the host's strength."

"What a rip-off."

He felt a pang at the cost of 5,000 points. That was worth the reward for a Jonin. But when he thought about how convenient a personal space would be, he gritted his teeth and decided, "Open a personal space."

The system fell silent. Then a warm current, different from the one he'd felt while learning ninjutsu, appeared inside him. A moment later, Shin saw that he had lost 5,000 points. At the same time, he sensed something strange in the space beside him.

With a thought, a rift in space opened beside him. Shin looked inside. It was about three square meters in size. There was no air, and he couldn't sense time passing. Living things couldn't be stored inside.

"Not bad." Shin nodded, put the contracts inside, then brought them back into his hands with a thought. It was incredibly convenient.

After tossing in a bunch of Kunai, shuriken, and Explosive Tags, Shin closed the space.

"All right, now I can finally redeem a Mangekyo eye technique. I worked so hard to hunt down the Blood Ninja for this moment."

In the original story, the Mangekyo's various eye techniques had been downright overpowered. Mastering one could even bring a qualitative improvement in strength. Shin silently brought up the system's ninjutsu redemption interface and found the Mangekyo eye techniques section.

Amaterasu, Tsukuyomi, Flame Control Kagutsuchi, Kotoamatsukami, Intangibility, Kamui...

Looking at the eye techniques, Shin was practically drooling. "I want them all, but I only have enough points for one. This is so frustrating."

At that moment, countless thoughts clashed fiercely in Shin's mind. Should I pick Amaterasu and just agree to go to the battlefield with Madara? Though its track record in the original story was a little underwhelming, it'd still be great for clearing out weaklings. I could just glare at people across the battlefield with my Sharingan. They'd all be points...

After thinking it over again and again, he pushed the idea aside. He'd leave it for now. Amaterasu wasn't powerful enough and could easily be dodged with the Substitution Technique by someone strong. He could consider it later.

Tsukuyomi was out, too. It was a genjutsu that required him to use it at close range, looking someone in the eye. With his current strength, there was no way he could pull it off.

Kagutsuchi... Give him a break. He didn't even have Amaterasu yet. Was he supposed to redeem this just because he had too many points to throw around? Out.

Kotoamatsukami!

At the sight of it, Shin's breathing quickened. Kotoamatsukami—the strongest genjutsu in the original story. It could issue any command to someone without restriction, even making them his slave. It was an absurdly unreasonable ninjutsu.

At that moment, he truly felt the urge to ignore everything and redeem it right away.

But he held back. Kotoamatsukami's effects looked wonderful, but it had some obvious drawbacks. For one thing, with a ten-year cooldown, it was basically a one-use ninjutsu.

And this technique also required looking someone in the eye to use. Shin imagined what it would be like if he redeemed Kotoamatsukami and tried to hypnotize Uchiha Tajima.

A Kage-level Expert like Uchiha Tajima had the sharp instincts that came from fighting on the battlefield. If Shin approached recklessly and showed even the slightest sign that he wanted to control him, he'd most likely be met with a flash of lightning and a sword strike. Even if Shin escaped using the Flying Thunder God or Crow Clone, he'd have to flee from then on, with the Uchiha Clan's kill order hanging over him.

Thinking of that, Shin hurriedly shook his head. Honestly, his strength was too low. He'd save controlling a Kage-level Expert for later. Besides, 15,000 points wasn't that hard to get.

As for Intangibility, now that he had the Flying Thunder God, he didn't need it urgently. Out.

As for Kamui, he was just missing a powerful attack right now. Rasengan posed little threat to anyone at Elite Jonin rank or higher, and Kamui's spatial disintegration ability would make up for that perfectly. Besides, people in the Warring States Period weren't very prepared for this kind of bizarre ninjutsu. If he used it unexpectedly, he might be able to kill a Peak Jonin—or even threaten a Kage-level Expert.

"System, redeem Kamui."

"Kamui, Mangekyo eye technique, rank S. Cost: 10,000 points. Requires the Mangekyo Sharingan. The host has the Three-Tomoe Sharingan. Can be forcibly redeemed for an additional 5,000 points. Sufficient points. Redeem?"

"Yes!"

When Shin saw his points drop to zero, a warm current poured into his left eye. At once, heat flared in his right eye, only gradually fading after a long while.

Shin opened his eyes. The Three Tomoe in his left eye looked even more sinister. He grinned. He was probably the first ninja in history who could use a Mangekyo eye technique with the Three-Tomoe Sharingan.
