Marvel: Trading with Worlds

As soon as he returned to the ninja world, Kushina grabbed Kain by the collar and asked angrily,

"Where did you take Sister Tsunade to play? It's disgusting. With Naruto not here, you all went off to who-knows-where!"

"There's nothing I could do about it, Kushina."

Kain sighed lightly. His acting instincts kicked in immediately, and he lied smoothly,

"Besides me, you're the strongest in the ninja world. If all of you left, and hidden enemies showed up to attack those who stayed behind, it would be dangerous. Only you could protect them."

Kushina and her family didn't completely buy it, but their expressions softened.

They believed him six or seven tenths of the way.

Besides, they had recently discovered Ōtsutsuki Ichishiki, and by all accounts, Kushina was indeed the strongest besides Kain. After some groaning, she said,

"Alright then. But once the enemy is dealt with, you have to take me to see Naruto."

"No problem at all!"

Kain agreed instantly and then asked about the enemy's situation.

Kushina didn't delay. She immediately informed Nawaki and Senju Tobirama to rush over. Compared to everything else, eliminating the cancerous threat lurking in the ninja world was the top priority.

Interestingly, the Shell Organization had been discovered almost by coincidence. The current Shell Organization was completely different from what it would become later—fewer members and limited support.

Moreover, many of its members were using the Red Queen's computer network.

Since the unification of the five major nations into the Federation of Fire, Nawaki had governed well, and the development of computer networks had advanced rapidly.

Now, the ninja world was on the verge of entering the home computer era.

The Shell Organization was exposed when one of its members transferred a large sum of money, drawing Red Queen's attention. Tracing the network trail, almost all Shell members were identified.

"So this is the place where Ōtsutsuki Ichishiki resides... and where the Ten Tails is kept."

After reading the intel, Kain nodded quietly. All potential Ten Tails locations had been spotted by satellite, then confirmed via robotic investigation.

However, Ōtsutsuki Ichishiki himself was elusive. With his spatial abilities, tracking his movements was nearly impossible.

"Leave the Shell members to me. Big Brother and Nawaki's Wood Style isn't suited for pursuit."

While most Shell Organization members weren't too difficult to handle, Senju Tobirama chose to lead the team personally. Once he planted the Flying Thunder God seals, escape was nearly impossible for the targets.

As for Ichishiki, Kushina suddenly said with keen interest,

"Leave him to me. I want to try fighting an Ōtsutsuki."

"Fine by me. I'll handle spatial lockdown and keep a close eye on him."

After considering it, Kain agreed to Kushina's request. While her sealing barriers were excellent, he preferred using magic to lock space, supplemented by Kamui. If Ichishiki tried to flee, Kain could instantly open a space portal to intercept.

With goals and roles assigned, Kain began preparing alchemy items to seal the space.

This task was simple for him. While working on refining avatars, he also made time to pair his daughter with Nono , Mikoto, and Nohara Rin.

The next day, Senju Tobirama had already set out with his team.

Kushina, now dressed in her battle attire, stood ready. Although Kain had prepared many outfits from other worlds for her, she still preferred the ninja world's attire.

Seeing her ready, Kain placed a hand on her shoulder and said,

"Let's go."

With that, he cast Apparition and teleported them to the place where the Ten Tails was kept.

Kushina glanced around and said curiously,

"This place feels strange. Why would a monster hide so many buildings here? Isn't that just asking to be discovered?"

"They probably haven't seen things like satellites before. Plus, most people in the ninja world never come to places like this."

Kain observed the identity markers related to the remaining Ōtsutsuki and speculated silently that there might only be a few actual Ōtsutsuki left.

Otherwise, the identity structures here must have been built by Ichishiki himself after arriving on Earth.

After storing the alchemy items meant to lock the space, Kain took one last look at the building Ichishiki left behind.

"This seems like a place where they store identity data or personal markers... But that's not important now. First, we deal with the monster, then wait for Ōtsutsuki to show himself."

Ten Tails still had a connection to Ichishiki. If Kain removed it, it would surely trigger a reaction, summoning him.

This Ten Tails was still a juvenile and required a massive amount of energy to grow. As for its energy source, Kain planned to consult Orochimaru to check on the status of his Pure Land research.

"Kamui."

Space twisted violently as the Ten Tails cub was sucked into the world of Kamui and sealed with a magical circle.

At the same time, Ōtsutsuki Ichishiki—far away in the ninja world—abruptly felt his connection to the Ten Tails vanish.

His face twisted in surprise and rage as he immediately began preparing to teleport to its location using his spatial powers.
