DXD: Naruto Recreation System

Itachi teleported to the Thunder Ninja Village and opened his system interface. "I want to summon characters from the Naruto world," he declared.

A translucent window appeared before him, displaying a list of characters with their respective costs.

"After upgrading the shop, can I summon characters from Boruto as well?"

[Yes, you need level 3 in the shop.]

"Okay then, let's buy all the tailed beasts to reach it," he decided without hesitation.

[Ding! You have purchased all nine tailed beasts.]

Itachi watched the points drain from his balance. "Well, it doesn't hurt seeing more than a billion points disappear like that… maybe because they weren't collected by me," he mused.

The reason Itachi spent so many shop points was simple: by acquiring the tailed beasts, he could not only become their Jinchūriki but also borrow their immense chakra reserves. With this purchase, his power had multiplied many times, and he was now confident he ranked among the lower end of the top ten in this world.

The tailed beasts appeared with a golden light in the village outskirts, their massive forms towering over the landscape.

"This world is strange," said Shukaku, the One-Tail, examining his surroundings. "But it's full of strong beings. We'll need to stay alert."

Kurama, the Nine-Tails, chuckled mockingly. "Stay alert? Who are you fooling, Shukaku? I can still fight any powerful being in this world. The number of beings I can't handle can be counted on one hand… but you? You might not even make the top 100. Or perhaps the top 1,000."

Shukaku growled, his massive form bristling with anger. "What did you say, Kurama?!"

The other tailed beasts began to back away as Shukaku prepared to attack Kurama. However, before he could act, Itachi appeared with a clap of his hands.

"Enough," Itachi said firmly. His Sharingan flared, and the sheer pressure of his presence silenced the beasts. "You are free to roam this world, but do not destroy anything in my village. I need the scientific equipment here intact."

Unwilling to challenge Itachi's authority, the tailed beasts dispersed to explore their new environment.

Inside the Raikage's Office

Having upgraded the system shop to level 3, Itachi summoned Orochimaru, Kabuto, and Amado, Kara's most brilliant scientist, renowned for his intellect and innovation. The three men now sat before Itachi in the Raikage's office.

"Let's talk," Itachi began, his voice calm but commanding.

After explaining their roles to them, Orochimaru leaned back, a sly smile playing on his lips. "I never thought I would have these weapons to myself. But aren't you worried, Itachi? Without these tools, won't your strength fall?"

Itachi met Orochimaru's gaze without flinching. "With the power of the nine tailed beasts, I don't need them anymore."

He turned to Kabuto. "You understood everything, right?"

Kabuto adjusted his glasses, a faint smirk on his face. "Yes. Though I never imagined I'd be using the Reanimation Jutsu again."

Itachi smiled faintly. "This time, you'll need to take it even further."

Kabuto's smirk grew wider. "Understood. I'll surpass even my previous work and create an army of reanimated ninjas, devils, angels, beasts, and many more powerful beings just for you."

Finally, Itachi looked at Amado. "Your task is the most difficult. You need to create clones using White Zetsu in large quantities. Additionally, you must integrate all the weapons, armor, and artifacts we obtained from the devils into them. On top of that, I want you to replicate the Sacred Gears and incorporate them into scientific ninja tools."

Amado steepled his fingers, his expression calm and calculating. "It is a difficult task, but I can do it without anyone's help," he said confidently. "However, if you can provide me with a more advanced lab, I can complete the work even faster."

Itachi nodded and summoned White Zetsu, instructing it to purchase cutting-edge equipment using the devil currency he had earned from the devils.

"You will get your equipment by the end of the day. But keep in mind, Orochimaru can assist you if you require it," Itachi added.

Amado smirked. "I won't need his help."

Orochimaru chuckled, his voice dripping with amusement. "Bold, aren't you? But I'd like to see how far you can go."

As they concluded their meeting, Itachi stood and addressed the group. "We have a lot to accomplish. Kabuto, start preparing your reanimation forces. Amado, I expect progress on the scientific tools soon. Orochimaru, merge those weapons quickly, and also keep an eye on the tailed beasts to ensure they don't cause unnecessary trouble."

Unknown to them, their work would soon give rise to a force so powerful that even the chief gods of various pantheons would tremble and human race will be recognised as one of the strongest.

After all, who would not fear humans capable of summoning the dead back to life, wielding an army of nearly 500,000 at the rank of low and mid class created by Amado, and Itachi possessing weapons stronger than both Divine Divide and Boosted Gear combined?
