Of course. Adding that layer to Deva's abilities provides a powerful trump card with a unique, character-specific drawback. Here is the revised chapter with the new details woven in.
Chapter 10: The Bridge Builder of Wave
The weeks following their team assignment became a monotonous blur of chores disguised as missions. The team's frustration grew into a palpable, grumpy cloud that followed them everywhere. Finally, after a particularly humiliating mission that involved retrieving a politician's runaway pet ferret, Naruto snapped.
They stood in the Hokage's office for their report. "No way!" Naruto shouted, making an X with his arms. "No more kiddy missions! I've had it! I'm a powerful, top-tier ninja and I want a real, exciting, super-challenging mission! Something that will let me show off what I can really do!"
Iruka, who was in the office reviewing scrolls, immediately began to scold him. "Show some respect, Naruto! You're a brand new genin! You have to build experience and prove your reliability!"
"He's a moron," Sasuke said, his voice a low, cutting murmur from the back of the room. "...But he's right. We're not learning anything of value."
Kakashi, who had been engrossed in his little orange book, glanced up at Deva. The silver-eyed boy had been silent the entire time, but he gave a single, almost imperceptible nod. The data from D-rank missions had yielded all it could. It was time for a new variable.
The Third Hokage watched them, a long, thoughtful puff of smoke leaving his pipe. He saw Naruto's desperate ambition, Sasuke's cold demand for a challenge, and Deva's quiet, logical assessment. He saw Kakashi's confidence in them.
"Very well," Hiruzen said, his voice taking on a serious tone that cut through the arguments. "You want a real mission, you'll get one." He pulled a thick scroll from his desk. "This is a C-rank. You will be bodyguards on an escort mission."
Naruto's eyes lit up. "Who is it?! A princess? A feudal lord?"
"Don't be so impatient," the Hokage chuckled. "Bring him in."
The door opened and an old, sake-flushed man stumbled in. He wore a towel on his head, carried a bottle in his hand, and reeked of cheap liquor. He took one look at the four genin and sneered.
"What's this? A bunch of snot-nosed kids?" he slurred, pointing a shaky finger. "You expect me to believe these brats are ninja? Especially the short, blond one with the stupid face. He looks like a real dummy."
Naruto instantly bristled. "Hah! Who's the dummy, you old drunk?! I'll take you down in one shot!"
"This is Tazuna, a master bridge builder," the Hokage explained, his voice hiding a hint of amusement. "You will escort him safely back to his home, the Land of Waves, and protect him until his bridge is complete."
Tazuna took another swig from his bottle. "My bridge is very important. I expect you to get me there in one piece, even if it costs you your lives."
Kakashi stepped forward, his visible eye curving into a smile. "It will be our pleasure. Team 7 will prepare immediately. We meet at the main gate in one hour."
An hour later, Deva walked down the stairs from their apartment, his pack filled with kunai, shuriken, and soldier pills. His mother, Shiori, was waiting for him at the door of the flower shop, wringing her hands.
"You're leaving the village," she stated, her voice trembling slightly.
"It's a C-rank mission. Just an escort," he said, his tone even.
"I know, I know. It's just..." She took a deep breath, her fear palpable. "The world outside the walls is dangerous, Deva."
He hugged her and said, "I will be careful, Mom. You don't have to worry."
Shiori's fear easing slightly, she says, "Mm, you come back safe."
At the main gate, the rest of his team was assembled. As they prepared to depart, Deva did a silent assessment of himself. The years since he copied Naruto's blueprint had been transformative. He could feel the vast ocean of chakra within him, his stamina immense. His ninjutsu was precise, and he held the secret of the Great Fireball Jutsu, perfectly replicated after seeing it only once. His taijutsu, learned through relentless observation and mimicry, was now an equal to Sasuke's, though the Uchiha's skill with weaponry was still superior.
He held another, far more powerful secret. On the night of Naruto's graduation, Deva had felt a seismic chakra event from across the village—hundreds of identical, stable energy signatures appearing at once. He didn't know it was the forbidden Multi Shadow Clone Jutsu, only that he had sensed the frequency for perfect, solid replication. After a few simulations in mind, he managed to copy it in a single stroke. However, the jutsu came with a severe drawback unique to him. Each clone was its own sensory antenna, and creating more than a handful at once flooded his mind with a disorienting storm of noise, making it almost impossible to think. It was a powerful, but dangerous, last resort.
He felt a quiet confidence as he walked. In the world of the Academy, Sasuke had been the benchmark for 'genius'. Now that Deva could match him, he felt prepared for anything a C-rank mission could throw at him. It was the confidence of a prodigy who had never truly been tested.
"Alright, everyone's here," Kakashi said cheerfully. "Let's move out!"
With that, Team 7 and their client walked through the massive gates of Konoha. The familiar, dense hum of the village faded behind them, replaced by the softer, more natural energy of the forest. The air was fresh, the road was clear, and for the first time, they were truly in the world as shinobi.
Naruto was practically bouncing, pointing out every bird and oddly shaped rock. Sakura was trying to engage Sasuke in conversation, who was ignoring her in favor of scanning the trees. Kakashi walked with a relaxed gait, reading his book.
As they walked, Deva had his own senses extended. He could feel the life-hum of the trees, the skittering energy of small animals in the undergrowth, the steady, rhythmic pulse of his teammates. And he could feel their client. Beneath the reek of sake, Tazuna's energy was a tight, coiled knot of fear. This was no simple mission.
Hours passed. The sun was high in the sky. Deva noticed it first. A subtle change. The gentle hum of the forest—the insects, the birds, the animals—had gone silent.
He scanned the path ahead. A fifty meters on, there was a large puddle in the middle of the road. It hadn't rained in days.
His senses focused on it. And then he felt it. A cold, sharp, discordant hum. It was alien to the natural feel of the forest. Two distinct, hostile chakra signatures, submerged and waiting. He looked at Kakashi. Kakashi looked back and gave a faint smile.
Then, they were close. Thinking Kakashi didn't get the signal, he opened his mouth to give a warning, but he was a fraction too late.
Two figures erupted from the water in a blur of motion. Metal chains tipped with sharp claws shot out, wrapping around Kakashi from two different directions.
"What—?!" Naruto yelled.
With a sharp tug, the chains pulled taut, and in a spray of blood, Kakashi Hatake was torn to pieces.
