"What?! The Munch-Munch Fruit can be used like this? You've already created two types of super alloys so quickly?"
"If we have this chakra-conducting alloy, doesn't that mean Konoha will never run out of chakra weapons?"
"Not just weapons—even armor could see a major upgrade!"
Tsunade was completely shocked.
This was an incredible breakthrough!
"Pretty much! Next, I'll have the village collect a large amount of ordinary metal ores to mass-produce these two alloys."
"At the same time, I'll also have the village and the contract holders gather more minerals and even rare plant and animal materials from both worlds to continue experimenting with new alloys."
Kaito nodded as he spoke.
"Got it."
Uchiha Naori also nodded. "I'll have my clan gather more materials as well. When the time comes, we'll produce more of these alloys for our own use."
"But more importantly, that Human-Human Fruit… Is it really as amazing as you said? Can it really boost a person's talent and comprehension?"
If true, that would be an invaluable treasure.
Hearing this, Mikoto and the others eagerly turned to look at Kaito.
They wanted it!
"It should be!"
Kaito nodded with confidence. "I've analyzed it thoroughly!"
"But to know the exact effects, someone will have to eat it and test it out. Any volunteers?"
Since he could extract the fruit's power at any time, there was no risk involved.
"I'm in!"
"Me too!"
"Count me in!"
Kushina, Mikoto, Minato, and Tsunade all raised their hands instantly.
Who wouldn't want a fruit like this?
"Here it is. You guys can decide among yourselves."
Kaito flipped his hand, revealing the Human-Human Fruit and placing it on the table.
Rather than choosing someone himself, he figured it was better to let them sort it out.
In the end, Minato was the first to back out.
After a fierce competition between the remaining three, Kushina finally won the fruit.
Without hesitation, she took a bite and ate it.
After a while—
"So? How do you feel? Do you feel like your brain just leveled up?"
Tsunade and the others stared at her curiously, eager for an answer.
"Uh…"
Kushina hesitated for a moment before replying, "I don't feel anything particularly special. I do sense a stronger connection to my body and better control over it. Also, my mind does feel clearer… but other than that, I don't notice any major changes."
Saying this, she turned to Kaito. "Kaito, are you sure you didn't get it wrong?"
"Impossible!"
Kaito shook his head. "Try training or studying a technique and see for yourself."
"Just feeling it out won't prove anything."
Since the fruit was supposed to enhance comprehension and learning ability, the only way to verify its effects was through practice.
"That makes sense!"
Kushina's eyes lit up as she immediately teleported to the backyard training ground to begin practicing her cultivation technique.
Kaito and the others quickly followed to observe.
Before long, the person most familiar with the technique—Kaito—noticed something shocking.
With every repetition of her training, Kushina's understanding of the technique was improving rapidly.
At least ten times faster than before!
"Holy—! It actually works!"
Tsunade and Uchiha Naori both gasped in disbelief.
Mikoto and Minato, being slightly weaker, couldn't perceive the full extent of the change.
After a while, Kushina finally reached her physical limit and had to stop.
She looked down at her hands, eyes sparkling with excitement.
"This is insane! It's like I just got a cheat code! The Human-Human Fruit is OP!"
"This has to be the strongest Devil Fruit ever! I've decided—I'm keeping it!"
But the next moment, Tsunade smacked her on the head.
"Ow!"
Kushina winced and looked up to see Tsunade standing there, arms crossed. She pouted, eyes filled with resentment. "Tsunade-nee, what was that for?"
"Hah! You deserved it!"
Tsunade smirked. "You really thought you could keep this brokenly overpowered fruit all to yourself? Dream on! We'll be taking turns using it."
With this kind of monstrous comprehension boost, there was no way she was going to let it go.
With the fruit's help, she was certain that her Flying Thunder God technique, Sage Chakra refinement, and other skills would improve at an insane rate.
Her path to surpassing Kage level would be dramatically shortened.
Even Uchiha Naori couldn't resist.
"I agree. Keeping this fruit locked to one person is a complete waste. Like Tsunade said, we should all take turns using it."
"After all, everyone has a limit to how much they can train in a day. We can rotate usage so that the fruit is always benefiting someone."
"Of course, even if we take turns, there still won't be enough time for everyone to use it daily. But a two-day or three-day rotation should work fine."
"What do you guys think?"
He glanced at the others.
"Sounds good!"
"I think it's fair!"
"Agreed!"
One by one, they all nodded in agreement.
In the end, Kushina could only look at Kaito with a pleading expression.
Kaito sighed helplessly. "This is what everyone decided. I can't do anything about it!"
"Fine! We'll take turns using it then! There are seven of us here, including Lady Mito. One person per day—how does that sound?"
He also wanted to experience the effects of the fruit himself.
As for the fact that he had already eaten a Devil Fruit and hadn't fully integrated with it yet?
That wasn't a problem at all. He could temporarily extract the Rumble-Rumble Fruit from his body or even seal it away for the time being—both options were completely viable.
In fact, since he had already removed the will of the Devil Fruits, he could even consume two Devil Fruits simultaneously as long as he kept their energies separated, preventing them from clashing and causing his body to collapse.
"Alright!"
"Sounds good!"
"We don't have much choice anyway!"
With everyone in agreement, Kushina could only accept it—though she was a little disappointed.
At least she'd still get to use it once a week, right?
What's that? Worried that removing the Devil Fruit would make it ineffective?
That wasn't an issue at all!
She was using it to enhance her comprehension of techniques, not for its physical powers. Whether the Devil Fruit was inside her or not didn't matter. Once she learned something, it became her own ability.
This wasn't just about developing Devil Fruit powers—it was about true mastery.
"Actually, there's another benefit," Kaito added. "Since we're all taking turns using this fruit, our collective energy will enhance its power over time."
"Just like how Devil Fruits become stronger as generations of users develop them, this one will continue to grow in strength as we use it."
Tsunade's eyes lit up. "So, the more we use it, the more powerful it will become?"
"Exactly!" Kaito nodded firmly.
"That's amazing!"
Everyone was thrilled. This was a huge advantage!
Following that, at the group's request, Kaito took them into the Space-Time Gate to extract the Human-Human Fruit, allowing everyone to experience it firsthand.
Even Uzumaki Mito was brought in to test it out.
Once everyone had their turn, Kaito handed the fruit's power over to Kushina and said, "Let's not count today—we've already wasted a lot of time! We'll officially start the rotation tomorrow."
"Also, I've been thinking… we don't actually train for a full day, right? If only one person uses it for an entire day, it's kind of wasteful."
"So why don't we divide the day into three shifts? That way, we can maximize the fruit's potential!"
"I can leave a shadow clone in the Space Gate to handle the extraction and reassignment of the Devil Fruit power. How does that sound?"
Since everyone needed to sleep at some point, using a full day per person would waste precious time. A rotating schedule would make the most of the fruit's effects.
Everyone's eyes brightened at the idea. "That actually makes a lot of sense! This way, we can maximize its efficiency."
"Alright, let's do it!"
Seeing that everyone was on board, Kaito confirmed the new rotation schedule. He also set up a separate space in the Space Gate and stationed a permanent shadow clone there to manage the Devil Fruit's distribution. Of course, to prevent memory overload, he would dispel and replace the clone daily.
Otherwise, if he let the shadow clone accumulate ten or fifteen days' worth of experience before dispelling it, even with his powerful mental strength, the flood of memories would be overwhelming.
There was no need to overdo it.
"By the way! Now that we're using the Human-Human Fruit, what about Chopper? Where is he? What do we do about him?"
At that moment, Mikoto suddenly remembered and turned to ask Kaito.
Clearly, she was quite fond of Chopper, that adorable little reindeer.
It would be a shame if he just disappeared like that.
"Oh, right!" Kushina and the others also turned their attention to Kaito.
Kaito chuckled. "I knew you guys would ask! Here he is!"
With a wave of his hand, he summoned a sleeping Chopper into the room and explained, "I've been thinking about this too."
"Giving him back the Human-Human Fruit isn't really an option."
"This fruit is way too important for us now."
"But if we don't give him anything, he'll just become a regular reindeer again."
"That would be cruel to him."
"So, I plan to use my Primal Chakra Refinement Technique to help him condense his own chakra seed, turning him into a true ninja beast and awakening his spiritual intelligence."
"Once he reaches the required level of intelligence, I'll form a contract with him and teach him new techniques to further enhance his abilities."
"What do you guys think?"
This was the best solution he could come up with.
"That actually sounds like a great idea!"
Tsunade, Uchiha Naori, and Minato all nodded in approval.
Mikoto and Kushina, however, furrowed their brows slightly.
Mikoto hesitated before saying, "But… if we do it this way, Chopper still won't be able to transform into his original future self, right? He won't be that same adorable and intelligent Chopper anymore…?"
