"To disrobe is to invite death."

  In the Sengoku era, the bathhouse was the ultimate trap. When a warlord removes his armor, sheds his silken robes, and sets aside his blade, he is nothing but soft flesh awaiting the assassin's steel. A steamy room is the perfect place to die—the thick white mist obscures vision, the sound of splashing water masks the footsteps of an attacker, and the victim is entirely stripped of their defenses.

  That is why the men of the Hattori clan were often tasked with standing vigil outside the steaming wooden tubs of Lord Ieyasu. We were the iron shield that guarded the vulnerable.

  Here, in the year 2026, my duty had escalated. I was no longer merely guarding the door. I was leading the Warlord directly into the boiling waters myself.

  "Lord Sato," I whispered, my voice echoing off the stark white, brightly lit tiled walls of the Sunset Harmony Elderly Care Grand Bath. "Step carefully. The floor is slick with the invisible slime of the water-kami."

  Mr. Sato, a veteran of perhaps eighty-five grueling winters, stood beside me in the antechamber. He was frail, his shoulders hunched with the invisible weight of a long, arduous campaign of life. His skin resembled the delicate, translucent parchment used for imperial decrees. He grasped the metal handrail bolted to the wall, nodding slowly.

  "The floor is a bit slippery today, Hattori-kun," he said, his voice a gentle, wavering croak.

  "Do not fear, My Lord," I vowed, stepping in front of him to scout the path.

  I was currently clad in the facility's specialized water-combat armor. My chest and thighs were covered by a heavy, impermeable blue vinyl apron that smelled strongly of chlorine and medicinal herbs. On my feet, I wore thick, yellow rubber boots that squeaked with terrifying, squealing volume against the wet tiles. I had mentally designated these boots as the Mizu-gumo—the water spiders of modern industry. They were heavy and lacked the stealth of straw sandals, but they gripped the slick porcelain earth with an iron tenacity.

  I maintained a low, wide center of gravity. I utilized Suriashi—the sliding step of the swordsman. I did not lift my feet; I glided the yellow rubber soles across the soapy tiles, maintaining continuous contact with the earth to prevent a fatal loss of balance.

  "The path is secure!" I announced, extending a hand to hover just inches from Mr. Sato's elbow, ready to catch him should his center of gravity falter.

  We reached the central washing station. A small, low stool of yellow plastic awaited him. I assisted Lord Sato onto the stool, applying the principles of Koppojutsu—the martial art of manipulating the bone structure—in reverse. Instead of exploiting the joints to break an opponent's balance, I supported his elbows and knees, guiding his fragile skeletal frame into a seated position with the gentleness of a falling cherry blossom resting upon a still pond.

  "Ah, good," Mr. Sato sighed, resting his hands on his bony knees. "My back is quite stiff today."

  "I shall purge the stiffness from your meridians!" I declared, reaching for my designated weapons.

  I grasped the cleansing artifact—a yellow synthetic sponge—and pumped three exact dollops of white alchemical gel from a plastic bottle labeled 'Moisturizing Body Wash'. I squeezed the sponge repeatedly with a rapid, pulsing grip until it foamed, creating a massive, dense cloud of white, floral-scented bubbles.

  This was the most perilous part of the mission. The Lord's skin was terrifyingly fragile. I could see the blue veins mapping the back of his hands like rivers on an ancient map. If I applied the standard, heavy-handed pressure used to scour the mud and dried blood from a breastplate, I would surely flay the man alive. The "Curse of Brittle Marrow" (osteoporosis) haunted the elders of this facility, making their bones susceptible to the slightest excessive force.

  I closed my eyes, recalling the teachings of my father in the hidden valleys of Iga. To touch without striking. To strike without cutting.

  "Secret Art: The Scrub of a Thousand Strokes!"

  I engaged my wrists, allowing my elbows to go completely loose. I became a flurry of controlled, localized motion. I moved the foaming sponge across his back with blinding speed, but applied absolutely zero downward force. I was merely gliding the foam across his parchment-skin, using the high velocity of the sponge to generate a purifying friction without ever digging into the flesh.

  Swish-swish-swish-swish-swish!

  "Oh my," Mr. Sato chuckled, his eyes closing in deep contentment. "That tickles a bit, but it's very thorough. You have the hands of a craftsman, Hattori-kun. Usually, the other staff are in such a rush."

  "I am a weapon forged for your comfort, My Lord," I replied, wiping a heavy bead of sweat from my brow. The humidity in the Grand Bath was suffocating, a localized jungle designed by the facility's heating system to test my cardiovascular endurance.

  Once the Warlord was fully encased in the white, fragrant foam, it was time for the rinse.

  I unhooked the silver serpent from the wall—the handheld showerhead. I aimed it at the plastic basin on the floor and squeezed the trigger mechanism. A jet of water erupted. I thrust my left hand directly into the stream, utilizing the sensitive skin on the back of my wrist to test the temperature, just as one would test a blade's edge.

  It was a precise 38 degrees Celsius. Perfect. No boiling traps had been set by rogue assassins in the boiler room.

  I adjusted the angle, turning the Serpent upon Lord Sato, methodically washing away the foam, the dirt, and the fatigue of his day.

  He stood up slowly, gripping the handrail tightly. It was time for the final phase of the operation: the submersion into the Grand Tub, a massive pool of steaming water that smelled faintly of sulfur and pine.

  But then, the unthinkable happened. Disaster struck.

  As I reached with my left hand to guide him toward the edge of the tub, my wet vinyl apron swung outward and caught the edge of the plastic soap dish sitting on the counter.

  A fresh bar of soap—a solid, perfectly smooth brick of slick green alchemy—was launched into the air.

  Time dilated. The roar of the splashing water faded into a dull, distant hum.

  My eyes locked onto the green projectile. It traced a fatal, parabolic arc toward the wet tiles, descending directly into the exact path where Lord Sato was blindly preparing to place his bare, wet foot.

  If that soap hit the ground, it would become the 'Sliding Poison Stone.' A hidden, frictionless landmine. The absolute moment the Warlord shifted his body weight onto it, his legs would fly out from under him. His fragile, hollow bones would shatter against the merciless, unyielding white ceramic of the floor.

  I would have failed my Lord. I would have failed my duty. I would be a stain upon the Hattori name!

  "NO!"

  I abandoned the silver Serpent. It clattered loudly to the floor, whipping around wildly like a dying snake and spraying water across the walls.

  I did not have time to bend at the waist. I had to intercept the projectile mid-flight, below the knee line.

  I dropped my weight entirely, throwing my legs out into a full, agonizing split on the slippery tiles. My thigh muscles screamed in fiery protest as my center of gravity plummeted toward the earth.

  As my torso dropped rapidly, I whipped my right arm out in a desperate, reverse-grip snatch—the exact same explosive kinetic motion used to catch a returning boomerang shuriken out of the air.

  SMACK.

  My palm slammed hard against the wet tile. My fingers clamped shut like the iron jaws of a bear trap.

  I froze. I was breathing heavily, my chest heaving against the waterproof apron. Water sprayed against the back of my neck from the rogue showerhead thrashing on the floor behind me.

  I slowly opened my eyes and looked at my right hand.

  Trapped firmly between my index and middle finger, gripping it with white-knuckled intensity mere millimeters from the floor and exactly one inch from Mr. Sato's descending heel, was the bar of green soap.

  "Hattori-kun?" Mr. Sato asked, looking down at me in mild confusion. He had paused his step. "Why are you doing the splits on the floor?"

  "I am... inspecting the structural integrity of the grout, My Lord," I wheezed, my hamstrings trembling violently as I maintained the extreme, punishing posture. "It is... flawless. You may proceed."

  "That's very diligent of you. You young people are so limber," he smiled warmly, stepping safely over my extended arm and slowly lowering himself into the warm, steaming waters of the Grand Tub. "Ahhh... paradise."

  I collapsed fully onto my stomach, letting the cold, wet tiles soothe my burning muscles. I had saved him. The Warlord was secure.

  The water-dungeon was conquered.

  I returned to the Castle of Six Mats, completely and utterly drained of all physical and spiritual energy. The scent of lavender soap, sterile dampness, and medicinal powder clung to my skin despite my own vigorous purification rituals in the staff locker room.

  Aoi was sitting cross-legged at the low table, aggressively slurping a bowl of instant yakisoba while staring blankly at a glowing spreadsheet on her laptop. She looked like a soldier who had spent the last twelve hours fighting a war against cell formatting.

  I dropped to one knee in the narrow genkan, bowing my head until it touched the synthetic wood flooring.

  "Aoi-dono! I have returned victorious from the water-dungeon!"

  "Welcome back, Masa," she muttered, not taking her eyes off the screen. "Did you survive the nursing home shift?"

  I lifted my head, my eyes burning with the manic intensity of a thousand historical campaigns.

  "Barely! The warlords must be cleansed! I had to escort them into the boiling waters of the grand bath! The tiled floors were treacherous, laden with the invisible slime of the water-kami! And the Lord's skin! It is terrifyingly fragile! It is like ancient, weather-beaten parchment drawn over hollow reeds!"

  Aoi stopped chewing. She swallowed the noodles loudly, closed her eyes, and let out a sigh that seemed to drain the very life force from her lungs.

  "It's called assisted bathing, Masa," she said, her voice a flat, deadpan monotone that carried no joy, only infinite patience. "It's a standard caregiving procedure. Please tell me you didn't scrub Mr. Sato like you're trying to polish a suit of armor."

  "I used the Scrub of a Thousand Strokes!" I declared proudly, springing to my feet and demonstrating my blindingly fast, zero-pressure wrist technique in the air above the shoe rack. "I generated a purifying friction without bruising a single meridian! My speed was an absolute blur!"

  Aoi stared at my violently flapping hands.

  "You look like a hummingbird having a seizure," she said, turning her attention back to her laptop. "But as long as you didn't hurt him, fine. Just go hang up your damp clothes on the balcony, please. You're dripping mysterious bathwater on my genkan."

  "As you command, My Liege!" I bowed deeply.

  The modern world required profound adjustments. It required soft hands, chemical soaps, and degrading waterproof aprons. But as long as I drew breath, the elders of this era would not fall to the treacherous tiles on my watch.
