The sun had abandoned this realm, sinking behind the concrete mountains of the capital and plunging the world into a synthetic twilight. For the common civilian, the night is a time of slumber and vulnerability. For a shinobi of the Hattori clan, the night is a cloak. It is the battlefield where true wars are fought.

  I stood at the epicenter of the Sunset Harmony Elderly Care facility, positioned just outside the central command tent—a brightly lit enclosure the locals call the "Nurse's Station." The kunoichi of the night watch were huddled over their Luminous Slates, logging the vital signs of the slumbering warlords. The air was thick with the scent of lavender antiseptic and the heavy, rhythmic breathing of eighty ancient veterans dreaming of past conquests.

  "Hattori-san," the shift commander whispered. She was a stern woman with bags under her eyes that spoke of countless night raids. She handed me a heavy, black cylindrical artifact. "Take the flashlight. Do a sweep of the east wing. Check the doors, make sure everyone is in bed. Don't wake them up."

  I accepted the Tube of Trapped Daylight with both hands, bowing deeply. "My vigilance shall be absolute. No assassin shall breach the perimeter, and no warlord shall fall from their futon under my watch."

  She stared at me, her face completely devoid of expression. "Just... don't yell. People are sleeping."

  I nodded and turned toward the east wing corridor. The lights here had been extinguished, leaving only the faint, sickly green glow of the emergency exit signs. This was my domain. I reached up and secured the strings of my standard-issue white paper mask—a facial concealment device utilized by modern medical operatives—firmly over my nose and mouth.

  I did not turn on the flashlight. A light in the darkness is a beacon for arrows. A true ninja relies on the Yaso-gaeshi—the night-vision technique of staring into absolute darkness until the pupils dilate to capture even the faintest starlight bleeding through the barred windows.

  I engaged the Shinobi-aruki. I lowered my hips, bending my knees to absorb the shock of my own weight, and rolled my steps from the outside edge of the foot to the big toe. I moved down the linoleum hallway without producing a single decibel of sound. I was a phantom. I was the breath of the void.

  Room 201. Secure. The rhythmic snoring of Lord Takahashi echoed through the wood.

  Room 202. Secure.

  Room 203. Secure.

  As I approached the intersection near Room 204, the hairs on the back of my neck stood at attention. A shift in the air currents. A disruption in the ambient spiritual pressure of the hallway.

  I flattened my back against the wall, merging my silhouette with the shadow of a potted ficus plant. I slowed my heart rate using the Water Mirror breathing technique. I waited.

  From the darkness of the intersecting corridor, a figure emerged.

  It moved with a slow, dragging gait. Its arms hung loosely at its sides, swaying with an unnatural, bone-deep lethargy. It wore a pale, flowing garment that billowed like a burial shroud in the faint draft of the air conditioning. The figure’s head was bowed, its face hidden in the gloom.

  "A Yurei?" I breathed, my muscles tensing for a close-quarters engagement. "A vengeful ghost wandering the earthly plane?"

  But no. Ghosts do not possess physical mass. This entity’s slippered feet were making a faint, rhythmic shuffling sound against the floor. Scuff. Scuff. Scuff. I narrowed my eyes, straining my night vision. The entity was not a ghost. It was Lord Nakamura. An eighty-two-year-old veteran of the logistics division, known for his gentle demeanor and his terrifyingly fragile hip joints.

  But something was horribly wrong. Lord Nakamura’s eyes were open, yet they were entirely vacant. They reflected the green emergency light like dull glass marbles. He was not looking at the hallway. He was looking at a world I could not see.

  "The Mindless Puppet Technique," I concluded, horror gripping my chest. "An enemy sorcerer has invaded his dreams and hijacked his motor functions! They are steering his physical vessel toward his doom!"

  And what a doom it was. I traced his trajectory. He was bypassing the restrooms entirely. He was heading straight for the fire escape at the end of the hall. The heavy steel door that led to a sheer, concrete staircase descending into the abyss. If his fragile, osteoporosis-ridden frame were to tumble down those stairs, he would shatter into a thousand pieces.

  I could not allow the unseen puppet master to claim his prize. But I was faced with a severe tactical dilemma. I had heard the legends. To wake a sleepwalker abruptly is to sever the silver cord that tethers their soul to their body. If I shouted, or struck him, the shock might stop his ancient heart instantly.

  I had to intercept the vessel. I had to alter its course without alerting the hijacked mind. This required the softest of touches. I needed the Hojo-jutsu—the art of binding—but without the rope.

  I sprinted silently back to the linen closet near the command tent. I seized a thick, woven cotton blanket—a winter-grade defensive shield. I draped it over my arm and engaged the Shukuchi rapid-movement technique, compressing the distance between myself and the possessed Lord in a matter of seconds.

  The story has been illicitly taken; should you find it on Amazon, report the infringement.

  Lord Nakamura was merely three paces from the fire escape door. His hand, pale and trembling, was slowly rising to grasp the cold iron handle.

  "I deny you, Sorcerer," I whispered.

  I lunged forward, executing a flawless, low-altitude slide across the linoleum. I threw the heavy cotton blanket over Lord Nakamura’s outstretched arm, instantly smothering his grip and creating a soft, padded barrier between his flesh and the heavy metal door.

  He collided with my blanket-wrapped arm. The impact was minimal. He stopped, confused by the sudden obstacle in his path. He let out a low, guttural murmur that sounded like an ancient incantation.

  I did not speak. I moved to his right flank, wrapping the remainder of the blanket around his shoulders like a cocoon. I applied a gentle, consistent pressure to his center of gravity, pivoting his hips away from the door.

  Guide the water, do not block the river. I became a human rudder. I matched his slow, shuffling pace, leaning my shoulder into his blanket-wrapped form, softly steering him back toward the safety of the corridor. He resisted for a moment, his possessed muscles attempting to push back toward the stairs. I planted my boots, dropping into an Immovable Stance. He pushed against me, but he was pushing against a mountain.

  Slowly, the puppet master yielded. Lord Nakamura turned.

  I guided the wandering phantom down the hall, step by agonizing step. We bypassed the fire escape. We navigated the treacherous intersection. I steered him toward the Chamber of Purification—the restroom. If his body was acting on a primal urge to empty his bladder, I would facilitate the ritual to appease the possessing spirit.

  I pushed the sliding door of the restroom open with my foot. The motion-sensor lights flared to life, blinding me temporarily. Lord Nakamura simply blinked, completely unfazed by the sudden illumination.

  I guided him to the porcelain receptacle. I stood at attention, facing the wall to preserve his honor, while the automated systems of his hijacked body took over. The flush roared like a waterfall.

  "The ritual is complete," I noted, turning back. "Now, to seal the vessel back in its tomb."

  I re-applied the blanket, steering him out of the bright chamber and back into the dark corridor. The journey back to Room 204 felt longer than a march through the snowy peaks of Echigo. Every step required micro-adjustments to his trajectory. If he drifted left, I applied pressure to his right. If he faltered, I supported his elbows using reverse bone-manipulation techniques to keep his skeleton upright.

  Finally, we reached his bed. I gently pressed the back of his knees against the mattress. He collapsed backward, sinking into the soft futon with a long, rattling sigh.

  I pulled the blanket up to his chin, securing the edges tightly to prevent the unseen puppet master from extracting him again. I watched his chest rise and fall. His eyes finally closed. The vacant stare was gone. The soul had returned to the vessel.

  I wiped a heavy sheet of sweat from my brow. I had fought no armed men tonight, yet I was more exhausted than if I had dueled a hundred samurai. To protect a life without the use of violence is the heaviest burden a warrior can bear.

  I bowed deeply to the sleeping warlord and faded back into the hallway to resume my patrol. The night was still young.

  The sun had fully risen by the time I returned to the Castle of Six Mats. The morning light filtered through the thin curtains, illuminating the dust motes dancing in the air.

  Aoi-dono was sitting at the low table, a piece of toast hanging from her mouth as she frantically typed an essay on her Luminous Scroll.

  I unfastened my shoes and dropped to one knee in the genkan, my head bowed in a posture of triumphant exhaustion.

  "Aoi-dono!" I declared, my voice hoarse from a night of silent vigilance. "I have returned! The sun has set and risen, and my watch has ended! I successfully patrolled the silent corridors of the elderly fortress!"

  She didn't look up from her screen. "Welcome back, Masa. Did you fall asleep in the break room again?"

  "I did not close my eyes for a single second!" I retorted, rising to my feet and stepping into the room. "The darkness was fraught with peril! A shadow moved in the night! A wandering spirit, hijacked by an enemy assassin using the Mindless Puppet Technique! He sought to hurl himself down the stairs of doom!"

  Aoi finally stopped typing. She slowly turned her head, her eyes carrying that familiar, heavy weight of absolute exasperation. "A mindless puppet? Masa... was someone sleepwalking?"

  "His eyes were open, but his soul was absent! I had to intercept the phantom! I utilized a cotton net to bind his movements without waking him, lest his spirit be severed from his mortal coil! I steered him to the Porcelain Kappa, appeased the water gods, and sealed him back in his chambers!"

  Aoi stared at me for a long, agonizing moment. She took a slow bite of her toast, chewed, and swallowed.

  "Masa," she said, her voice deadpan and devoid of any dramatic flair. "It's just a resident sleepwalking to the bathroom. It happens like, three times a week in nursing homes. Don't tackle them."

  "I did not tackle him!" I protested, clutching my chest defensively. "I employed the softest of martial arts! I was a gentle river guiding a drifting log!"

  "Great. A gentle river," she sighed, turning back to her laptop. "Did you write it down in the shift report?"

  "I documented the successful repulsion of the phantom in the sacred ledger, yes."

  "Good. Now go take a shower. You smell like institutional soap and adrenaline."

  I bowed deeply. She did not understand the true stakes of the night. She saw only an old man walking in his sleep. She did not see the invisible threads of the puppet master that I had so masterfully severed.

  But a shinobi does not require recognition. A shinobi requires only victory. And last night, Lord Nakamura lived to fight another day.

  I retreated to the bathroom, preparing to face the true terror of the morning: the freezing jet of the bidet.

  Masanari’s Cultural Notes (Glossary):

  ? Yaso-gaeshi (Night Vision): A traditional ninja technique of adapting one's eyes to the darkness. By avoiding direct light sources and relying on peripheral vision, a warrior can navigate pitch-black corridors. Modern flashlights ruin this instantly and should only be used as bludgeoning tools.

  ? The Mindless Puppet Technique: A dark sorcery where an enemy takes control of a sleeping body. Modern physicians refer to this simply as "Somnambulism" (Sleepwalking), but I remain suspicious of the lack of soul behind their eyes.

  ? Soft Restraint (The Blanket Catch): In an era where striking a VIP is forbidden, a heavy cotton blanket serves as an excellent tactical net to safely alter a target's momentum without causing bruising or waking the host.
