Naruto: Puppet Master Undercover in Konoha

Another month had passed.

Excluding earlier local skirmishes, this full-scale war had already lasted over a year.

Over the past month, Shindai hadn't left his house at all—he'd been completely immersed in puppet research.

Thanks to Kushina Uzumaki bringing him meals every day, Shindai could focus entirely on his studies.

Kushina more than once suspected that Shindai was going mad.

Because on multiple occasions when she brought his food, she saw him with bloodshot eyes—clearly exhausted yet oddly excited and frenzied in appearance.

Seeing Shindai like this, Kushina didn't hesitate. She punched him straight in the face, forcing him into an unconscious state so he could finally rest properly.

Shindai's development of Kannazuki was accelerating rapidly, nearing completion.

Currently, Shindai was making skin for Kannazuki, although this version was different from the previous ones.

This time, the skin was still composed of magnetized Iron Sand Body, but each grain had been coated with real skin tissue by Shindai. He used magnetic force to adhere them to Kannazuki's exterior, creating what looked like genuine flesh.

In Shindai's hands rested a round yellowish-white iron sand ball. He threw this iron sand ball directly onto Kannazuki's body.

Upon contact with Kannazuki's frame, the ball immediately dispersed, spreading evenly across its surface.

Within seconds, the yellow-and-white grains had fully covered Kannazuki's body, forming a highly lifelike pale-yellow epidermis.

Looking at Kannazuki, Shindai couldn't hide his excitement.

He linked Kannazuki with [Chakra Threads], then flicked his finger.

Instantly, Kannazuki's right arm exploded apart into countless iron sand particles scattering outward—but halfway through the air, they abruptly halted.

If left unchecked, those flying grains would have pockmarked the room with tiny holes.

With another flick of his finger, the scattered sands gathered systematically, reforming the right arm exactly as before.

Then, Shindai moved his fingers again—the arm changed shape, transforming into a cannon barrel. At the same time, he activated [Raikō Ken], which instantly loaded a missile.

Getting increasingly excited, Shindai flicked his finger once more. Kannazuki's left arm detached and hovered midair, morphing into a cylindrical iron sand structure. Inside this column were also Raikō Ken Sealing Tags, and its outer shell was lined with densely packed holes, each housing a Senbon needle.

The only downside was that Shindai wasn't particularly skilled in poison application—although whatever little poison he applied still worked surprisingly well.

Inside Kannazuki were now three Raikō Ken Sealing Tags total. Two of them stored various ninja tools, while the third contained all sorts of missiles Shindai had crafted himself, making them instantly retrievable whenever needed.

Shindai's five fingers curled simultaneously, and both the senbon and other projectiles were resealed back into the sealing tags. The Iron Sand Body cylinder dispersed and reformed into his left arm, while Kannazuki's right arm returned to normal. The entire process was incredibly smooth and fluid.

Meanwhile, by studying the core ninja-tech documents provided by Minato Namikaze, Shindai had deepened his mastery of Magnet Release kekkei genkai to an entirely new level.

Magnetism is part of the electromagnetic force—specifically, it comes from magnetic fields. Its generation relates to objects' electron arrangements and interactions with magnetic fields.

Magnetic and electric fields are connected—when one changes, it creates the other.

In other words...

Shindai snapped his fingers, and instantly blue electrical currents surged all over Kannazuki's body.

At the same time, electrical sparks appeared at Shindai's fingertips too.

Now Shindai could easily generate electricity using only his Magnet Release kekkei genkai—not any jutsu like Lightning Release, just plain electricity produced purely through magnetism.

This phenomenon is known as electromagnetic induction—the process where kinetic energy transforms into electrical energy through magnetic fields.

These currents had many potential applications, though unfortunately inside a house, Shindai couldn't demonstrate most of their functions.

Looking at Kannazuki flickering with electric currents, Shindai chuckled while holding his forehead.

"Hahaha... It worked! It actually worked! What Red Sand Sasori? You're just trash! You couldn't beat me before, and now you're nothing but a fart behind my ass! Your human puppets? Total junk! My Kannazuki alone has left your pathetic creations a hundred miles behind!

I can't wait to try you out—crushing those pathetic Human Puppets beneath your feet!"

Just as Shindai was laughing joyfully, the door suddenly swung open.

"I could hear your cackling from far away already, Shindai. What exactly are you laughing—"

Kushina froze mid-sentence because Kannazuki's skin had just been completed, and Shindai hadn't dressed her yet. She was completely naked.

And here was Shindai, grinning at a totally nude Kannazuki—it definitely looked suspicious no matter how anyone saw it.

Shindai's laughter stopped abruptly as he suddenly realized something wasn't quite right either.

Smiling at a completely naked and beautiful Kannazuki—even if she was just a puppet—it would certainly look perverted to others.

Seeing Kushina's hair already starting to lift as if caught in windless turbulence, Shindai immediately turned pale.

This was the prelude to Kushina beating someone up.

"W-Wait, wait, Sister Kushina! It's not what you think!"

...

"So this is that new puppet you've been making lately, huh? Looks pretty impressive—it's so lifelike, almost like you stole your own twin sister's body or something."

Kushina stared at Kannazuki, clicking her tongue in amazement.

Shindai, with several large bumps on his head, stood with hands on his hips and proudly declared, "Kannazuki is not only beautiful — I'll say it plainly, there is no puppet in the entire ninja realm more powerful than my Kannazuki!"

"That's quite a claim," Kushina Uzumaki said with curiosity. "Earlier, I heard you laughing while cursing someone. Were you talking about that 'Sasori of the Sand'?"

Shindai scoffed disdainfully. "Of course. Sasori — the so-called genius puppet artisan of Sunagakure, hailed by all for mastering the pinnacle of puppet arts. In my opinion, he's nothing special — just an emotionally starved, despicable, shameless fellow. 

I'm the greatest puppet master — not only in Sunagakure, but in the entire ninja realm!"

Kushina gave Shindai a strange look. It was obvious how much he disliked this Sasori.

Her curiosity renewed, Kushina asked again, "Have the two of you ever fought in a puppet battle? Who won?"

Shindai answered confidently, "We've never actually fought — but when we do, I'll definitely win!"

"Cheh."

Kushina couldn't hold it in any longer and suddenly burst out laughing.

Curling the corner of his mouth, Shindai let out a "tch" sound. "Fine. Don't believe me then."

It was pointless trying to explain the workings of Kannazuki to someone like Kushina — a hopeless academic wreck who wouldn't understand anyway. Worse yet, she might get frustrated, fail to understand, and then make fun of him — which would only make him angrier. So Shindai decided it wasn't worth the effort to explain.
