Naruto: Under the Banner of the Clans

*** Naruto World ***

With a force of more than two hundred elite ninjas, the Yuki clan was tracking the demon that had attacked them two months earlier.

They had managed to find it several times, but without being able to kill it.

After several attempts, the chosen solution was finally to seal it once and for all.

To do this, they had called upon the Uzumaki clan for help.

It wasn't just the Yuki clan that wanted the demon dead and sealed. In the months that followed, several villages had been attacked, and the Daimyo of various countries had noticed the demon's malevolent presence.

It was through them that the demon-hunting mission had begun. Without significant compensation, even the Yuki clan, with all their thirst for vengeance, wouldn't have bothered to send two hundred elites for this pursuit.

The Uzumaki clan, on the other hand, was to send around twenty members to support the Yukis.

To finish the job once and for all.

Since the death of the young Uzumaki princess, their clan had declared war on the Uchiha clan. In this war, they needed supplies and provisions. For that, they needed money.

Thus, even though the clan needed men to support the war effort, they still had to find people to send on missions like the subjugation of a demon.

But as the group composed of Yuki was heading towards the meeting point with the Uzumaki, the tailless demon, Reibi, appeared in front of them, zigzagging at great speed through the trees, dodging ninjutsu and kunai.

Hundreds of arms extended from its body, and a terrifying smile appeared on its face.

Some ninjas at the vanguard, not paying enough attention, were killed by the demon's terrifying strength.

The demon could feel the waves of negative emotions from the ninjas around it, relishing in their hatred and anger.

The once lush forest was now covered in ice, with destroyed trees and a blood-red hue.

"How far are we from the rendezvous point!?" shouted one of the Yukis leading the group.

"Twenty kilometers!"

Looking at the demon, the leader made a quick decision and ordered his men, "Five of you go get the Uzumaki, the rest with me! We'll fight while moving towards the rendezvous point!"

Without the Uzumaki, they couldn't seal it. They didn't have the skills.

Fighting as best as they could, their chakra continuously depleted, dodging and pushing the beast in the right direction.

Who would have thought they'd encounter the demon so soon? They hadn't even begun to search for it when the demon was already before them.

But as the members of the Yuki clan fought Reibi, under the cover of the shadows of branches and leaves, Akeno was watching closely for any opportunity to act.

Yes. His target was Reibi.

The one that Reibi possessed would acquire simply incredible powers, as long as its user was careful not to create a disturbance in his chakra, which would cause the loss of his vital energy, pushing the body into a state of extreme deterioration.

But Akeno didn't intend to be possessed or absorbed by the demon.

He wanted to seal it within himself.

But unlike a Jinchûriki, a person who is a vessel for a tailed demon, Akeno planned to apply several different seals so as not to be completely a Jinchûriki.

Having the ability to produce dark chakra from negative emotions, Reibi was an extremely valuable asset.

Especially considering that in the film, Reibi only fed on negative emotions from simple villagers, mortals.

Emotions are obviously much stronger in a cultivator than in a simple mortal, given their spiritual power.

With this dark chakra, Akeno could gain enhanced strength, a significant increase in ninjutsu potency, and a second source of chakra.

Another interesting power is that Reibi has the ability to sense negative emotions.

Thus, with a new source of chakra far more powerful than a normal ninja's chakra, and the ability to sense negative emotions, Akeno wanted both to find the missing children more quickly and to have the ability to fight the mayor of Hope City.

Following the movements of the ninjas who were fighting, Akeno prepared to intervene. For the first time, his actions risked bringing about a change in the timeline of this world.

When they had saved the children from various clans, he hadn't altered the course of history. This time, he intended to capture Reibi and take him with him.

But considering that in the original story, Reibi had been killed or sealed, Akeno didn't think it would change the fate of this world much.

After all, Akeno still wanted to see the landscape of the village of Konoha and meet the various characters who lived there.

Forming hand signs, about twenty clones appeared around him. Continuing to form signs, the clones and he transformed into ninjas of different sizes, all with different faces, but especially with red hair.

Emerging from hiding and heading towards the fight, Akeno pretended to give orders to his clones. "Disperse! Prepare the seal!"

Over the past two months, Akeno had learned a lot about seals and had learned a seal capable of sealing someone or a demon within oneself.

After all, while many techniques hadn't been created yet, this wasn't the case for sealing techniques. Hagoromo Otsutsuki knew a great deal, and the Uzumaki clan likely carried his legacy.

Seeing about twenty ninjas bearing the symbol of the Uzumaki clan with red hair, the members of the Yuki clan naturally believed that the long-awaited reinforcements had arrived and redoubled their efforts.

Reibi, as strong as it was, couldn't hold out long against more than a hundred and fifty Yuki elites and began to lose its ability to move, caught by ice chains.

Taking advantage of this opportunity, Akeno and his clones began weaving hand signs.

Ten signs, then thirty, then a hundred...

The sealing technique was long, even after being simplified by increasing the number of people casting the technique.

Akeno had carefully considered the dangers of sealing this demon within himself, especially such a demon. But he didn't intend to become a Jinchûriki like Naruto or the others.

What he wanted was to seal it within him first. Without sharing chakra. A perfect seal that wouldn't allow any chakra to leak from the demon into his body.

This would allow him to remove the demon whenever he wanted without any repercussions or danger to his life.

It wasn't as if he could become friends with a demon like Reibi. It was better to ensure he could detach himself whenever he wanted.

After sealing it within him, he would use a second seal to extract the demon's powers in sufficient quantities without suffering from it.

This should give him the same powers as in the anime. Without the ability to fire a laser capable of destroying a village like the weapon that used Reibi's chakra.

This method was safer for him but less effective than a true Jinchûriki in battle.

He wouldn't be able to use a chakra amount beyond what he normally could, and he would have to concentrate to control the second seal to release the right amount of dark chakra.

Thus, this method had its advantages and disadvantages.

Finishing the hand signs, the twenty clones placed their hands on the ground, creating patterns that spread towards Reibi and then onto its body.

Meanwhile, on Akeno's body, a spiral pattern appeared over the spherical black mark already drawn on his abdomen.

The seal Kaede had applied to his abdomen would still allow him to seal his chakra as well as the demon's.

What Akeno was doing was just improving it to give it the capacity to contain Reibi.

With the hundred Yuki clan ninjas immobilizing the demon, the clones could apply the seals without any problems.

After a few minutes of struggling, the patterns finished spreading over the entire body of the demon, sealing its fate.

With that, Akeno approached and touched the demon with his hand. Gradually, the seal on Akeno's abdomen absorbed the demon into himself, causing the demon to disappear from everyone's sight.

Feeling the new presence within his body, locked within the seal, Akeno was glad that everything had gone well. It was the first time he had really risked his life.

If the Yuki clan ninjas hadn't been able to immobilize it, or if they had noticed that they weren't Uzumaki clan ninjas, he could have died.

Luckily for him, no one knew the multi-shadow clone technique yet, and the techniques displayed by them could only lead to the assumption that they were indeed from the Uzumaki clan.

As Akeno concentrated on the new presence in his body, the leader of the Yuki clan group approached Akeno with an undisguised smile on his face. "Well done! I must say, without you, we would never have managed to put an end to that thing."

Coming to his senses, Akeno saluted the man. "Thank you, it's also thanks to you that we were able to complete the seal without any problems."

They couldn't have been happier, the Yuki clan had gotten their revenge, and Akeno had captured the demon for himself.

"May I know your name?" asked the Yuki clan member.

Seemingly surprised, Akeno decided and responded with a smile, "Akeno. Call me Akeno."
