The day of observation yielded more than Seiji had anticipated.
He lay motionless on the ridge, his Tenseigan active, perceiving every thread of life within the estate. The guards' patterns were professional but predictable—rotating shifts every four hours, overlapping patrol routes that left narrow gaps in coverage. The watchtowers' sightlines were carefully arranged, but the terrain itself created blind spots. A dry riverbed, carved by ancient floods, ran along the estate's eastern edge. The watchtower there had a clear view of the approach, but not of the riverbed itself. A single guard patrolled that section every twelve minutes.
Seiji could cross in less than thirty seconds.
But the physical defenses were not what concerned him. His Tenseigan perceived something else—a network of chakra threads woven through the estate's foundations. Not seals. Something older. A summoning contract, dormant but present, its signature faint and ancient. It pulsed from a chamber deep beneath the main house, a place the guards' patterns carefully avoided.
Yoritomo had more than private security. He had a summon. Or access to one.
The coiled thing in Seiji's chest stirred. He had encountered summons before—Jiraiya's toads, Orochimaru's snakes, Hanzo's salamander. They were powerful allies, bound by ancient contracts that granted their summoners significant advantages. If Yoritomo had such a contract, eliminating him would require neutralizing his summon first. Or severing the contract itself.
He filed the information away and continued his observation.
Yoritomo himself was predictable. The noble woke late, took his meals in his study, and spent his afternoons reviewing ledgers and correspondence. He rarely left the main house, and when he did, he was surrounded by guards. His chakra was weak, civilian, utterly unremarkable. But his cold eyes, visible through the study window, held the calculated cruelty of a man who had ordered deaths without number and slept soundly afterward.
Seiji felt nothing for him. Yoritomo was a threat. A root cause. Eliminating him would save Konoha lives. The arithmetic was clear.
As dusk fell, Seiji made his final preparations. He had mapped every patrol route, every blind spot, every gap in the watchtowers' coverage. He had identified the chamber where the summoning contract pulsed—a sub-basement accessible through a hidden door in the main house's library. He had noted the safe room where Yoritomo would retreat if alarmed—a reinforced chamber behind his study, protected by earth-style barriers.
He would not give the noble time to reach it.

Night fell over the foothills like a shroud.
Seiji moved through the dry riverbed, his footsteps silent on the ancient stones. The patrol passed—a single guard, chunin-level, his chakra alert but not alarmed. Twelve minutes until he returned. Seiji crossed the gap in thirty seconds, flowing over the estate wall where the earth-style barrier's chakra matrix was weakest. His bone armor absorbed the impact of his landing, silencing what would have been a telltale thud.
He was inside.
The garden was manicured, alien in this harsh landscape. Cherry trees imported from Fire Country, their blossoms long since fallen. A koi pond, its surface still and dark. Stone paths winding between carefully arranged flower beds. Yoritomo had built a piece of Konoha's beauty in the heart of enemy territory, a monument to his wealth and his contempt for the village whose soldiers he funded to kill.
Seiji moved through it like a ghost.
The first guard died without a sound. Seiji's bone thread wrapped around his throat and severed his spine. The man crumpled, his golden thread fading. Seiji caught the body before it could fall, lowering it silently behind a ornamental hedge. One.
The second guard was patrolling the western perimeter, his route bringing him past the garden in approximately four minutes. Seiji waited in the shadows, his chakra suppressed to a whisper. The guard appeared right on schedule—a young woman with sharp eyes and a lightning affinity. She paused at the garden's edge, her hand resting on her kunai, her senses prickling. Something was wrong. She could feel it.
She couldn't see it.
Seiji's Gravitic Pulse crushed her throat before she could cry out. Her hands flew to her neck, her eyes wide with shock. His bone spike found her heart. Two.
He dragged her body into the shadows beside the first. Two guards down. Twenty-one remained.
---
The main house loomed before him, its pale stone gleaming in the starlight. Seiji perceived the guards inside—five signatures, moving through the corridors in overlapping patterns. Professional. Disciplined. But they were not prepared for him.
He entered through a second-story window, his bone threads manipulating the latch from the outside. The corridor beyond was empty, lit by flickering oil lamps. He moved toward the library, where the hidden door to the sub-basement waited.
The library was vast, two stories of shelves filled with leather-bound volumes. Yoritomo's wealth was displayed in every spine, every gilded edge. A fire crackled in a massive hearth, casting dancing shadows across the room. And standing before the hearth, a glass of wine in his hand, was a man Seiji had not expected to find here.
Not Yoritomo. Someone else.
He was tall, lean, with silver-streaked hair and cold gray eyes. His chakra was jonin-level, disciplined and controlled. He wore no visible weapons, but his hands were calloused in the pattern of a swordsman. And around his neck, on a simple leather cord, hung a small fang—a tiger's tooth, ancient and pulsing with dormant chakra.
The summoner.
"You're the half-breed," the man said, his voice calm. "The White Bone Baku. I wondered when Konoha would send you."
Seiji's Tenseigan activated fully. The man's chakra network was complex, layered with techniques Seiji didn't recognize. The tiger's tooth pulsed with a resonance that matched the summoning contract beneath the estate. This man was not just a guard. He was Yoritomo's true protector.
"You knew I was coming."
"I knew someone would come. Yoritomo has made many enemies. Konoha was the most patient." The man sipped his wine. "My name is Tora. I am the guardian of the Tiger Contract, bound to this estate for three generations. Yoritomo's grandfather saved my grandfather's life. In exchange, my family serves his. I am the last of my line."
Seiji calculated. The man was jonin-level. The tiger contract gave him access to powerful summons. A direct confrontation would be dangerous, possibly fatal. But the man was also bound by honor, by debt, by a contract that predated Yoritomo's crimes.
"Yoritomo funds the murder of Konoha shinobi," Seiji said. "He profits from war. His wealth is built on blood."
"I know. I've watched him become what he is. A predator who kills from safety, never staining his own hands." Tora's gray eyes were tired. "I am bound to protect him. The contract compels me. But I am not blind to what he is."
"Then step aside. Let me complete my mission."
"I cannot. The contract binds my will to his survival. If you try to kill him, I must stop you." Tora set down his wine glass. "But I am not required to kill you. Only to protect him. If you can disable me without death, the contract's hold weakens. If you can sever the contract itself..." He touched the tiger's tooth. "I would be free."
Seiji understood. The coiled thing in his chest calculated. Tora was offering him a path. Not to kill the guardian, but to free him. To sever the ancient contract that bound his family to Yoritomo's bloodline.
"Show me the contract," Seiji said.
Tora nodded and led him to the hidden door.
---
The sub-basement was cold and ancient, carved from living stone long before Yoritomo's ancestors built their estate above it. Torches flickered in iron brackets, casting dancing shadows across walls covered in faded murals—tigers, massive and powerful, hunting through forests that no longer existed.
At the chamber's center, on a pedestal of black stone, rested the Tiger Contract.
It was a massive scroll, its edges worn by centuries of handling. The names of summoners stretched back generations, each signed in blood. The most recent name was Tora's, written in a strong, clear hand. Above it, his father. His grandfather. A lineage of guardians, bound to serve the Yoritomo bloodline in exchange for a debt long since repaid.
Seiji's Tenseigan perceived the threads that bound the contract to Tora's chakra. They were thick, ancient, reinforced by generations of obedience. Severing them would require precision. Power. And something else—a willingness to take on the contract's burden himself.
"If I sever your bond," Seiji said, "the contract will be unbound. It will seek a new summoner. It may choose me."
Tora's gray eyes widened. "You would take on the Tiger Contract? Knowing nothing of its demands?"
"I would take on whatever is necessary to complete my mission and protect my people." Seiji met his gaze. "Is that acceptable?"
Tora was silent for a long moment. Then he nodded slowly. "My family has served the Yoritomo bloodline for three generations. We have watched them grow cruel, corrupt, drunk on wealth bought with blood. If the contract chooses you... perhaps it will find a worthier master."
Seiji placed his hand on the scroll.
"Severing Threads of Existence."
He didn't aim for Tora's life. He didn't aim for the contract's destruction. He aimed for the thread that bound the guardian's will to Yoritomo's bloodline—the ancient debt, the generations of servitude, the obligation that had become a prison. He pressed.
The thread resisted. It was old, strong, reinforced by centuries of belief. But Seiji's Tenseigan perceived its weak points—the places where Tora's own doubt had frayed the binding, where his disgust at Yoritomo's crimes had weakened the ancient magic. He pressed harder.
The thread snapped.
Tora gasped, stumbling back. The tiger's tooth at his neck pulsed once, then fell still. His gray eyes were wide, free. "It's... gone. The compulsion. The binding. I'm free."
"The contract is unbound. It will seek a new summoner."
As if responding to his words, the scroll blazed with golden light. Seiji felt something ancient and powerful brush against his mind—a presence, vast and predatory, evaluating him. The Tiger Clan, deciding whether he was worthy.
He was cold. Precise. Utterly without mercy for his enemies. But he was also a protector. He killed to save his people. He remembered every face, every thread he severed. The remembering kept him human.
The presence withdrew. The scroll's light faded. And Seiji knew, with absolute certainty, that the Tiger Contract had accepted him.
"You are the new summoner," Tora said, his voice awed. "The first in three generations not bound to the Yoritomo bloodline." He bowed deeply. "I cannot serve you—I am free now, and I will find my own path. But I will not stand in your way. Yoritomo is in his study. Do what you came to do."
Seiji nodded and walked toward the stairs.
