One Piece: Take the Uchiha Clan to the Grand Line

— — — — — — 

At that moment, Uchiha Kitaro led the group out of the Hidden Rain Village and into the open wilderness.

"My dear apprentice, now that we're out here, let's talk about what kind of reward you can offer me. I trust you'll make it worth my while," Orochimaru said with his trademark sly smile.

"Of course, my beloved Orochimaru-sensei," Kitaro replied with a smirk. "Have I ever let you down?"

He clenched his fist, and a dark sheen covered his arm as he activated Armament Haki. His skin turned pitch black like forged steel. Without hesitation, he unsheathed his blade and slashed at his own arm.

Clang!

The blade collided with his arm but left not a single scratch.

Orochimaru's eyes lit up with fascination.

"This is Armament Haki. Its main applications are coating, hardening, and projection," Kitaro explained. "Coating is like wrapping chakra around a kunai—it enhances attack and defense."

"Hardening greatly boosts your defense, so even a sword slash won't get through. And yes, it can work in tandem with chakra."

"Impressive," Orochimaru murmured, visibly intrigued. The idea of a defense capable of countering blades without weapons was groundbreaking, especially for ninja combat, where hand signs and speed are crucial. This technique could revolutionize battle dynamics.

Kitaro gestured for Shisui to turn around and performed a series of rapid movements. Shisui, without looking, accurately described each action.

"This is Observation Haki," Kitaro continued. "It allows you to sense an opponent's movements. Master it, and you can even glimpse into the future. Some people with unique talents can hear the voices of all things, including the thoughts of their enemies."

"Thanks to his Rumble-Rumble Fruit, Shisui's range of Observation Haki extends up to 10 kilometers. Within that radius, not only can he sense movements, but he can also hear conversations. No one can escape his detection."

Orochimaru's expression turned serious. He grasped the significance of such an ability. Most ninja rely on chakra and their senses to predict attacks, but Shisui's Observation Haki elevated this to a whole new level.

It wasn't just evasion—it was omniscient awareness. Stealth against Shisui? Impossible.

"Combine Observation Haki with Armament Haki, and you get a massive boost in combat effectiveness," Kitaro added with a grin.

Orochimaru nodded in agreement. The synergy between the two was undeniable.

"And finally, there's Conqueror's Haki."

A faint hum filled the air as Kitaro activated his Conqueror's Haki.

BOOM!

The sheer pressure cracked the ground around him, radiating a palpable force even to those standing a good distance away. It wasn't just a display—it was a tangible mental assault, shattering weaker wills.

Orochimaru's pupils contracted. His body instinctively shifted into a defensive stance, sensing the overwhelming danger. The mental shockwaves battered his mind, relentless and brutal.

"Conqueror's Haki is pure domination. Most inexperienced chunin wouldn't even last a second—they'd be knocked out cold the moment I release it," Kitaro explained.

Orochimaru frowned, contemplating the implications. Chunin formed the backbone of most villages' ninja forces. If this technique could incapacitate them en masse, it was a weapon of mass destruction in itself. It turned battles into one-sided massacres.

He glanced at the fractured ground under Kitaro's feet. "Something tells me this Haki does more than just intimidate."

"Sharp as ever, sensei." Kitaro smirked. "Conqueror's Haki isn't just for show. It can be imbued into fists and weapons, amplifying their power beyond what Armament Haki can achieve. And here's the kicker—it stacks with chakra and Armament Haki."

To demonstrate, Kitaro coated his fist with both Haki types and chakra. Turning toward a nearby hill, he launched a single punch.

BOOM!

The hill exploded into rubble, obliterated in an instant.

"That's insane!" Kakashi and Guy exclaimed in unison, their eyes wide with disbelief.

Shisui and Itachi, already familiar with the technique, remained composed, though their awe was evident. They had witnessed this destructive power before, albeit not at this level.

Orochimaru's breath hitched. The devastation was beyond anything he had seen. This wasn't a jutsu—it was raw, unrestrained physical power. A single punch had achieved what usually required complex ninjutsu or forbidden techniques.

Kakashi suddenly recalled something. "Kitaro... during your fight with the guy who had the Rinnegan, you didn't use this, did you?"

Kitaro nodded. "Nope. Didn't need to. His defenses had too many gaps. Honestly, I could've taken him down with just swordplay."

Kakashi blinked, confused. "Then why go all out? You didn't even need to power up like that."

Kitaro grinned, a mischievous glint in his eyes. "Don't you think it just looks cool?"

"…"

Kakashi had no words. Only Kitaro would prioritize style over efficiency in battle.
