The sensation of spatial displacement faded abruptly. The rushing tunnel of colors collapsed, leaving the group standing on solid, grey ground.
There was no wind. There was no scent of pine trees or damp earth. The silence was absolute and suffocating.
Hiashi Hyuga stumbled slightly as his boots met the chalky surface. He caught his balance, instinctively pulling his daughters close to his sides. Hinata and Hanabi stood completely still, their pale eyes wide as they processed the environment. Amado adjusted his spectacles, looking down at his feet and then up at the sky.
Orochimaru simply brushed a speck of grey dust from his cloak, his golden eyes sweeping the desolate landscape.
They stood on a vast, rocky plain. The sky above was an endless, pitch-black void filled with unblinking stars. Hovering massively over the horizon, casting a brilliant blue and white glow over the barren terrain, was the Earth.
"The gravity is lighter," Amado observed, his voice sounding flat in the thin atmosphere. He tapped his foot against the rock. "The physical density of the terrain is identical to ordinary stone, but the gravitational pull is significantly reduced. It requires an immediate adjustment to physical movement."
"Maintain a steady flow of chakra to the soles of your feet," Nanami instructed calmly. He stood a few paces ahead, his hands resting easily at his sides. "Anchor yourselves to the ground. If you leap with your standard strength, you will launch yourself entirely out of control."
Hiashi looked up at the massive blue sphere of their home world. The stoic leader of the Hyuga clan struggled to contain the shock rising in his chest. To stand upon the moon, a place restricted to ancient myths and fables, defied all shinobi logic.
"We are truly standing on the moon," Hiashi murmured. He looked toward the distant, jagged mountains of grey rock. "You said this is the origin of my bloodline, Sensei. Did the ancestors of the Hyuga build a settlement in this wasteland?"
"They did not build it in the wasteland," Nanami replied, pointing toward a massive crater in the distance. "They built it beneath the crust, closer to the core, where the environment was artificially stabilized. Hamura Otsutsuki chose this celestial body as a watchtower. His descendants have lived here for centuries, guarding the husk of the Ten-Tails."
Before Nanami could elaborate further on the history of the Otsutsuki, the ground beneath their boots shuddered.
It was a faint tremor at first, barely a vibration against the soles of their sandals. Then, a sharp, grinding sound echoed across the silent plain.
Nanami did not turn around. His eyes narrowed slightly. "Form a defensive circle. Now."
Hiashi reacted instantly. He stepped in front of Hinata and Hanabi, his hands shifting into the opening stance of the Gentle Fist. The veins around his temples bulged as his Byakugan flared to life.
Amado stepped back, taking shelter behind the Hyuga leader. Orochimaru did not retreat. The pale shinobi stepped forward to stand beside Nanami, a faint, intrigued smile touching his lips.
Fifty yards away, the grey crust of the moon fractured violently.
A massive plume of dust and pulverized rock erupted into the dark sky. From the center of the newly formed crater, a colossal shape hauled itself upward onto the surface.
It was a crustacean of nightmarish proportions.
The Giant Crab stood easily thirty feet tall. Its massive, segmented shell was a pale, chalky white, blending perfectly with the lunar terrain. Eight thick, spiked legs dug into the rock, supporting a heavy, armored body. Two gargantuan pincers, each the size of a small house, snapped together with a deafening, metallic clack. Its stalked, bulbous eyes swiveled independently, locking onto the intruders.
A thick, bubbling white foam dripped constantly from its mandibles, hissing as it struck the dry rock.
Hinata gasped, stepping back slightly, her hands trembling. Hanabi stared up at the monster, her small fists clenched bravely, though her eyes betrayed her fear.
"A native organism?" Amado asked, pulling a small notepad from his cloak. His scientific curiosity completely overrode his survival instincts. "Fascinating. The sheer caloric intake required to sustain a biological entity of that mass in a barren environment suggests a highly adapted chakra-consumption system."
"It is not a random beast," Nanami stated, his voice calm and informative. He kept his hands at his sides, showing no intention of drawing a weapon. "It is the gatekeeper. It was placed here by the descendants of Hamura to guard the passage leading to their subterranean temples. It is highly aggressive and territorial."
Hiashi held his stance. "Its armor appears incredibly dense. My Gentle Fist can strike the internal organs, but penetrating a shell of that thickness requires significant force."
"Do not attempt to strike it with standard chakra techniques," Nanami warned the Hyuga leader. "Notice the foam dripping from its mandibles."
Nanami gestured toward the hissing white bubbles pooling beneath the crab.
"That foam is a specialized defense mechanism," Nanami explained. "It is highly reactive to chakra. If it touches you, it will instantly drain your reserves and completely neutralize any ninjutsu it comes into contact with. It acts as a dampening field. Furthermore, the creature's shell is heavily resistant to blunt force and elemental jutsu. It relies on continuous internal hydration to survive on the surface."
"A creature that nullifies chakra and repels physical trauma," Orochimaru hissed softly, his golden eyes wide with dark fascination. He ran a long, pale tongue over his lips. "An exquisite specimen. The biological adaptations required to forge an absolute defense against shinobi arts are magnificent."
The Giant Crab let out a low, clicking roar. It raised its massive right pincer and charged.
Despite its colossal size, the creature moved across the low-gravity environment with terrifying speed. The ground shook with every step of its spiked legs.
Hiashi prepared to push his daughters out of the path of the beast, but Orochimaru raised a single, pale hand.
"Allow me, Kento," Orochimaru requested, his voice dripping with eager anticipation. "I wish to test the limits of my new vessel. And I require a live subject for my laboratory. This creature will provide decades of valuable data."
Nanami looked at the Sannin. He recognized the hunger in Orochimaru's eyes. It was the same hunger that drove the man to map the human genome and unravel the secrets of immortality. Providing Orochimaru with a challenge was the best way to keep his dangerous intellect focused.
"You may engage," Nanami agreed. He stepped back, moving to stand firmly in front of the Hyuga family and Amado. A faint, invisible pulse of his Ten radiated outward, forming a protective boundary around the non-combatants. "Subdue it. Do not destroy the passage it is guarding beneath the crater."
"I will be meticulous," Orochimaru promised.
The Sannin stepped forward, walking directly toward the charging beast.
Orochimaru did not draw the Blade of Kusanagi. He did not weave hand signs for his serpent summons. He closed his eyes for a fraction of a second, reaching deep into the core of his newly altered cellular structure.
Years of agonizing experimentation and absolute mental discipline alongside Amado and Tsunade had culminated in this exact state. He had successfully integrated the raw, divine genetics of Shibai Otsutsuki into his own body, anchoring the volatile power with a modified, synthetic Karma seal designed by Nanami.
Orochimaru opened his eyes.
The transformation was immediate. The black, geometric lines of the Karma seal erupted from his left palm, spreading rapidly up his arm and wrapping across his neck and face. His already pale skin took on an unearthly, luminous white hue. A single, smooth, pale horn broke through the skin on the left side of his forehead, curving backward slightly.
But the most profound change was his eyes.
The golden, reptilian irises vanished. The sclera of both eyes turned a pitch, bottomless black. Surrounding the pupil was a glowing, pale-green ring that twisted in the shape of an infinite loop—a serpent swallowing its own tail.
This was the Uroborogan. The unique Dojutsu awakened through the synthesis of his own snake-like affinities and the divine Otsutsuki genetics.
A heavy, ancient, and suffocating chakra flooded the lunar plains. It was not the cold, venomous aura Orochimaru usually projected. It was a dense, crushing weight that felt detached from humanity entirely.
Hiashi flinched, his Byakugan struggling to process the sudden, overwhelming density of the chakra network flaring before him. "His life force... it has completely mutated. He is no longer human."
"He has ascended," Amado muttered. "The biological integration is perfectly stable."
The Giant Crab closed the distance, bringing its massive right pincer down in a devastating, crushing arc intended to cut the pale shinobi in half.
Orochimaru did not dodge backward. He simply pushed off the ground.
Utilizing the inherent ability of the Otsutsuki physiology to manipulate gravity and achieve flight, Orochimaru ascended smoothly into the dark sky. He floated effortlessly backward, allowing the colossal pincer to slam into the rock where he had been standing a millisecond prior. The impact shattered the crust, sending a shower of grey debris flying.
The crab clicked furiously, raising its head to track the floating target. Its mandibles opened wide, and a massive, surging torrent of the white, chakra-neutralizing foam erupted from its mouth, shooting toward Orochimaru like a pressurized geyser.
"Standard ninjutsu will dissolve upon contact," Orochimaru murmured to himself, floating backward to maintain distance. "A test of biological manipulation is required."
Orochimaru raised his right hand, pointing his open palm toward the incoming wave of foam.
He did not channel elemental chakra. He tapped into the unique, rule-breaking power granted by his ascension.
Shinjutsu: Uwabami no So. (Genesis of the Great Serpent)
This Shinjutsu was the ultimate realization of Orochimaru's lifelong obsession with the manipulation of flesh and life. It allowed him to instantaneously rewrite the genetic code and cellular properties of any organic matter he infused with his chakra, altering its biological function on a fundamental level.
A pulse of pale-green energy fired from Orochimaru's palm, striking the center of the massive wave of foam.
The reaction was instantaneous. The white bubbles did not neutralize the green energy. Because it was a Shinjutsu—a divine miracle rather than standard chakra—it bypassed the crab's dampening defense entirely.
The foam stopped moving mid-air. The thick, white bubbles rapidly hardened, changing color from white to a deep, sickly grey. The liquid structure of the foam was instantly rewritten, calcifying into a dense, heavy, rock-like resin.
The massive wave of hardened resin crashed down upon the crab.
The creature shrieked, a high-pitched clicking sound, as the heavy, hardened mass of its own altered defense mechanism collapsed over its front legs and mandibles, severely restricting its movement.
"Fascinating," Orochimaru noted, floating gently back down to the ground. "Its own secretions can be easily weaponized against it. The biological structure of the foam is highly receptive to cellular alteration."
The Giant Crab struggled violently against the hardened resin. It tore its front legs free, cracking the calcified foam. Enraged, the beast lunged forward again. It ignored the foam this time, opting for pure, overwhelming physical destruction.
It swung both of its massive pincers in a synchronized, horizontal pincer maneuver, aiming to crush Orochimaru between the two heavy claws.
Orochimaru stood perfectly still on the grey rock.
The Uroborogan in his eyes spun slowly, the green infinite loop glowing against the black sclera.
The Uroborogan was a Dojutsu of biological perception. It did not merely see chakra pathways like the Byakugan, nor did it read muscle tension like the Sharingan. The Uroborogan allowed Orochimaru to see the exact cellular lifespan, biological weaknesses, and the precise nervous system pathways of any living organism. He could see the heart beating, the neurons firing, and the exact cluster of nerves that controlled the beast's massive limbs.
Orochimaru saw the central ganglion—the cluster of nerve cells serving as the creature's brain—located deep beneath the thick armor of its ventral thorax.
"The armor is too thick to pierce with a standard blade without causing fatal internal hemorrhaging," Orochimaru analyzed aloud, watching the pincers close in from both sides. "I must bypass the shell entirely."
A fraction of a second before the two massive pincers crushed him, Orochimaru moved.
His physical speed, enhanced by the Otsutsuki body, was blinding. He ducked beneath the closing claws. The pincers slammed together above his head with a deafening clash of thick shell.
Orochimaru slid directly beneath the underbelly of the giant crab.
He looked up at the pale, segmented armor protecting the creature's stomach. He aligned his vision perfectly with the central nerve cluster he saw pulsing through his Dojutsu.
He raised his right hand, forming his fingers into a rigid spear.
He did not attempt to punch through the shell. He utilized his Shinjutsu once more.
Shinjutsu: Hebigami. (Serpent God's Grasp)
This specific application of his power allowed him to project his biological manipulation through solid matter, striking the internal cellular structure without needing to physically pierce the exterior defense.
Orochimaru thrust his hand upward, striking the solid shell of the underbelly.
A pulse of pale-green energy shot from his fingertips, passing harmlessly through the thick, chalky armor of the crab. The energy traveled directly into the beast's internal cavity and struck the central nerve ganglion with absolute, surgical precision.
The green energy did not destroy the nerves; it simply rewrote their conductive properties, shutting down the transmission of electrical signals from the brain to the limbs.
The Giant Crab froze instantly.
The massive pincers, which had been preparing to strike downward to crush the pest beneath it, went completely limp. The eight spiked legs lost all tension.
The colossal beast collapsed downward.
Orochimaru smoothly glided out from underneath the falling creature, stepping casually to the side as the massive body hit the lunar surface with a heavy, dull thud. A cloud of grey dust billowed outward.
The Giant Crab lay entirely motionless. Its eyes still swiveled slightly, indicating it was alive and conscious, but its entire body was completely, biologically paralyzed.
Orochimaru stood beside the fallen guardian. The black markings of the Karma seal slowly receded from his face and arm, pulling back into the palm of his hand. The single horn retracted into his skull. The black and green Uroborogan faded, replaced once more by his slitted, golden eyes.
He let out a soft, satisfied hiss, running a hand over the thick shell of the beast.
"A complete shutdown of the motor cortex," Orochimaru noted to himself. "The biological integrity of the specimen remains one hundred percent intact. It is a perfect capture."
He reached into his cloak and pulled out a massive, unrolled storage scroll. He tossed it onto the ground near the crab. He bit his thumb, smearing blood across the sealing array.
"Fuinjutsu: Specimen Containment."
A large cloud of smoke erupted, instantly enveloping the thirty-foot beast. When the smoke cleared, the Giant Crab was gone, neatly stored within the complex sealing matrix of the scroll. Orochimaru rolled the heavy parchment up, tying it securely and placing it into his pack.
"Excellent," Orochimaru smiled, turning back to the group. "The guardian has been removed. And I have acquired a fascinating subject for my return to the village. The day is already a success."
Amado walked forward, a look of deep, professional respect on his bearded face. "Your application of the Shinjutsu was flawless, Orochimaru. To bypass physical matter to alter a neural pathway... it opens up entirely new avenues of medical and combat science. The integration is performing above projected metrics."
"The power of the gods is a useful tool," Orochimaru agreed smoothly.
Hiashi released his defensive stance, letting out a long, slow breath. His Byakugan faded, the veins around his eyes receding. He looked at the pale Sannin. He had always known Orochimaru was dangerous, but seeing the man wield the power of a god with such casual, terrifying precision sent a chill down his spine. The forces protecting Konoha were no longer merely human.
Hinata peeked out from behind her father, her pale eyes wide with shock. Hanabi looked at the spot where the giant crab had been, her mouth hanging slightly open.
"That was amazing!" Hanabi declared, pointing at Orochimaru. "You made the giant crab go to sleep with just one poke!"
Orochimaru looked down at the seven-year-old girl. A faint, surprisingly genuine smirk touched his lips. "Science, little one, is the ultimate weapon. It allows you to dismantle monsters without breaking a sweat."
Nanami stepped forward, lowering the invisible barrier that had protected the group. He walked past the spot where the beast had fallen, moving toward the deep crater it had emerged from.
"The harvest is concluded," Nanami stated, his voice calm and authoritative. He looked down into the dark, jagged hole in the lunar crust. "The beast was resting atop the access point. The tunnel beneath leads directly to the subterranean settlements of the Otsutsuki descendants."
He turned back to the group, his sea-green eyes holding a serious, unyielding focus.
"Stay close. The gravity here is light, but the enemies below will not be slow. The descendants of Hamura possess the Byakugan, and they have guarded their isolation for centuries. They will not welcome visitors from the Earth."
Hiashi stepped forward, his posture rigid and disciplined. "We are ready, Sensei. My daughters will not falter, and I will protect them."
"Ensure that you do, Hiashi," Nanami nodded. "Amado, Orochimaru. We proceed downward. Keep your sensory perception sharp."
Nanami stepped off the edge of the crater, floating smoothly down into the dark abyss. Orochimaru followed, his golden eyes scanning the shadows. Amado and the Hyuga family descended after them, leaving the silent, star-filled void of the lunar surface behind.
They moved deeper into the moon, descending toward the forgotten history of the ninja world, preparing to uncover the ancient secrets that had been hidden since the era of the Sage of Six Paths.
