Chapter 10: Boogie Woogie Arrives

Kenta woke up on the morning of his fifth birthday with a sense of anticipation. The first rays of sunlight streamed through the windows of his room, casting a golden glow over the wooden floors and shelves lined with books and trinkets. He stretched lazily, letting out a small yawn, ready to face the day. But as he sat up, a sudden sharp pain shot through his head.

"Ow!" Kenta clutched his temples, wincing as the pain intensified. It wasn't the kind of pain he could ignore—it was as if someone was shoving a glowing hot needle directly into his brain.

"What the hell is this?" he groaned, his voice muffled as he buried his face in his hands. The ache spread, pulsing like a second heartbeat, and then, as suddenly as it had started, the pain stopped.

Kenta blinked, his vision clearing, and then he froze. Information—vast, complex, and impossibly detailed—flooded his mind. It wasn't just memories or vague ideas; it was a complete understanding of something entirely new.

'Boogie Woogie.'

The promised technique had arrived.

'While I am happy that I have finally gotten my cheat ability but it would have been better if it had appeared without any pain.' Kenta groaned before focusing on the information about his ability or rather Kekkei Genkai.

At first, Kenta wasn't sure if he was imagining it, but as he focused, the information clicked into place, piece by piece. The technique wasn't just about clapping his hands and switching places—it was far more intricate, deeply rooted in the manipulation of chakra.

The first thing Kenta realized was that the technique required him to infuse chakra into his hands before clapping. The infused chakra acted as a marker, creating an invisible "link" between two objects, people etc. He had to know the exact location of the person or object too.

Once the link was established, the clap acted as a trigger, swapping the positions of the marked targets instantaneously.

It was a bit like the Flying Raijin technique used by Minato Namikaze, but without the need for physical seals. Instead, Kenta could mark anything simply by focusing his chakra on it. The trade-off, however, was that Boogie Woogie was heavily reliant on his chakra reserves and control.

Each clap consumed around 10 percent of his current chakra. At his current level, that meant he could use the technique ten times before completely exhausting himself. The good news was that as his chakra capacity grew and his control improved, the cost would decrease significantly.

Someday, with enough training, he could clap thousands of times in a single day without breaking a sweat.

As the information settled in his mind, Kenta's lips slowly curled into a grin. Then he began to laugh—a full, belly-aching laugh that echoed through his room.

"This is insane," he muttered, rubbing his hands together. "This is absolutely insane! Do you know what I can do with this? Oh, wait—of course, I know! I just downloaded a manual for it into my brain! I have a fucking space time jutsu."

His excitement was palpable. He scrambled out of bed, his bare feet hitting the cool wooden floor as he paced the room. The possibilities raced through his mind like fireworks.

"I can mark kunai with my chakra and teleport behind enemies like the Yellow Flash . I can switch places with anyone mid-fight like Sasuke Uchiha. Hell, I can even mess with people just for fun! Imagine swapping someone's bowl of soup with a bowl of poop at dinner!"

The sheer versatility of the technique was staggering. It wasn't as outright destructive as Gojo's Infinity or Sukuna's Cleave, but it had infinite potential for strategy and misdirection.

And for someone like Kenta , it was the perfect fit.

Kenta took a deep breath, calming his racing thoughts. "Alright," he muttered to himself. "Time to see if this actually works."

He focused, closing his eyes as he extended his senses inward. He could feel his chakra, a warm, pulsing energy flowing through him. It was larger and more vibrant than it had been before—probably because he had recently turned five and had been training to balance his physical and spiritual energy.

"Focus," he told himself. He stretched out his hand, channeling his chakra into his palm. It felt strange at first, like a faint tingling sensation, but he pushed through it. He opened his eyes and looked around the room for something to test the technique on.

His gaze landed on a small wooden stool by the window.

'Perfect.'

Kenta concentrated, letting his chakra flow from his hand toward the stool. He imagined it as a link—a thin, invisible thread connecting him to the object. The stool shimmered faintly for a moment, a barely perceptible glow that confirmed the connection had been made. He was pretty sure that the shimmer could be seen by just him.

"Okay," Kenta muttered, clenching his fists. "Here goes nothing."

He clapped his hands.

The sound echoed sharply through the room, and in an instant, Kenta found himself standing where the stool had been. The stool, in turn, had taken his place by the bed.

Kenta froze, his mouth hanging open. "It … worked," he whispered. Then a grin split his face, and he threw his arms in the air. "It worked! Holy crap, it actually worked!"

He clapped again, swapping back to his original position. This time, he felt a faint wave of fatigue wash over him—not overwhelming, but noticeable.

"So that's the chakra cost," he muttered, placing a hand on his stomach. "Ten percent per clap. Not bad, but I've got a long way to go before I can use this without worrying about running out of juice."

Over the next few minutes, Kenta tested the technique relentlessly. He swapped places with pillows, chairs, and even a potted plant he found in the hallway. Each time he clapped, the process became smoother, and his understanding of the technique deepened.

He discovered that the chakra cost wasn't fixed; it depended on the distance between him and the marked object. The farther away the target was, the more chakra it consumed.

"This is going to be so broken once I master it," Kenta said with a smirk, leaning against the wall to catch his breath. "Flying Raijin has nothing on me."

But he also realized the limitations. His current chakra reserves were too small to use the technique frequently, and his control was still rough around the edges. If he wasn't careful, he could burn through his chakra in minutes.

Despite the limitations, Kenta couldn't help but feel excited about the potential of Boogie Woogie. The information downloaded into his mind had included hints about advanced applications of the technique—things that even the original user, Aoi Todo, hadn't fully explored.

For example, Kenta could theoretically mark multiple objects at once, allowing him to create a network of targets to swap between. He could also experiment with marking moving targets, like shuriken or kunai, to create dynamic strategies in battle.

And then there was the possibility of combining Boogie Woogie with other jutsu. The thought sent shivers down Kenta's spine. He could already imagine swapping places with a clone mid-fight, or using the technique to set up devastating ambushes.

"The god wasn't kidding when he said this has room to grow," Kenta muttered, a small smile playing on his lips.

As Kenta sat cross-legged on the floor, sweat beading on his forehead, he thought back to the god's final words.

"Start training your body as soon as you stop pooping in your diapers."

It had seemed like a joke at the time, but now it made perfect sense. Without a strong body and better chakra control, Boogie Woogie's potential would be wasted. His spiritual energy might be abundant, but his physical energy was still catching up, and that imbalance was holding him back.

"Alright," Kenta said, determination lighting up his eyes. "Time to step up my game. If I want to make the most of this, I'll need to train harder than ever."

He clapped one last time, swapping places with the stool again. Despite the strain, he couldn't help but grin.

"This is going to be fun."
