Iron bone

Chapter 3: Lubrication and Lies

The tea room was silent, save for the rhythmic, dying clack-clack of Kaito’s jaw against his own chin. The shard of rusted iron had burrowed deep, anchoring itself into the core of his synthetic anatomy. Hidetada, wide-eyed and shivering, slid out from under Kaito’s frozen, iron-clad grip, scurrying toward the door like a startled rat.

"You're not so tough now, you oversized teapot," Hidetada sneered, dusting off his robes. "Enjoy the rust, Kaito. I’ll send someone to haul your carcass to the scrap heap by morning."

Kaito couldn't move, but he could watch. He watched the Lord exit, his heavy, iron-weighted boots refusing to lift. With a final, agonizing lurch, Kaito tipped forward, smashing through the floorboards once more and into the crawlspace, then dragging his heavy, unresponsive bulk out into the cool night air. The journey back to Gen’s hut was a blur of mud, curses, and the sound of his own joints screaming in protest.

THUD. SCREEE-CLANG.

Kaito collapsed onto Gen’s porch, his iron hand punching a crater into the wood. The front door creaked open, spilling warm, amber light onto his prone form.

[ "Well, if it isn't the local disaster," ] Gen muttered, peering down over his spectacles. [ "You look like you tried to hug a landslide and lost. Did you kill him, or did you just provide the furniture with a new ventilation system?" ]

[ "He’s dead," ] Kaito hissed, steam venting from his collar. [ "But I think... I think I’m finishing the job he started. Something snapped inside." ]

Gen didn't offer a hand. He kicked Kaito’s chest plate with his boot, listening to the hollow ring. [ "Stop vibrating like a dying cicada. Get inside. And for the love of the forge, don't break the door frame this time." ]

Kaito dragged himself inside, leaving a trail of black, viscous fluid and dirt on the pristine tatami mats. He collapsed into the center of the room, his weight causing the floorboards to bow dangerously.

[ "Look at you," ] Gen sighed, walking over with a small vial of iridescent, glowing liquid. [ "You went for a walk as a man and came back as a junk pile. That shard you felt? It’s not just metal. It’s the Shogun’s mark. They didn't just use scrap; they used magnetized ore." ]

[ "Magnetized?" ] Kaito groaned, his voice flickering. [ "Why does that matter?" ]

[ "Because, you bucket of bolts, your heart—or what’s left of the pumping mechanism in your chest—is being pulled toward your spine by that jagged bit of iron. It’s like a slow-motion stake through the heart, except the stake is magnetic and your body is a giant, thirsty magnet." ]

[ "Can you fix it?" ]

[ "I can delay it," ] Gen said, pulling out a heavy wrench. [ "But you need to be lubricated with this alchemical solution. It’s rare, expensive, and smells like a wet dog’s armpit. Drink up." ]

[ "I don't have a stomach, Gen! How am I supposed to—" ]

[ "Pour it into the valve on your neck," ] Gen commanded, shoving a funnel into the gap between Kaito’s neck plates. [ "And stop complaining. You’re lucky I haven't turned you into a garden shed yet." ]

As the fluid hit his internal furnace, a sensation of icy relief washed over him, followed by a violent, shuddering twitch. Kaito’s arm shot out, punching through the wall of the hut.

[ "Oops," ] Kaito muttered.

[ "That’s the third wall this week," ] Gen grumbled. [ "You’re an economic catastrophe. You know that? A normal assassin would just use a blade. You prefer to reconstruct the architecture of every building you enter." ]

[ "I'm not an assassin, Gen. I'm a structural liability." ]

[ "You said it, not me." ]

Suddenly, the air in the room grew heavy. The hairs on the back of Gen’s neck stood up. A shadow flickered across the paper window, moving with a speed that defied human grace.

[ "Get down, old man," ] Kaito barked, his internal sensors whirring to life, detecting a metallic signature outside—a high-frequency, sharp ping of honed steel.

[ "Who is it?" ] Gen whispered, his humor vanishing.

[ "Someone who smells like a bounty hunter. And they’re fast." ]

The door didn't just open; it dissolved into ribbons. A figure stepped into the room—a lithe, masked mercenary dressed in tight-fitting dark leather, holding two short, curved blades that glowed with a faint, pulsing violet light.

[ "The iron man," ] the stranger mused, tilting their head. [ "You’re harder to track than a common thief, but your 'clank' carries for miles. Lord Hidetada’s second-in-command was quite clear: bring back the head. Or, in your case, the entire torso." ]

[ "You're late," ] Kaito growled, trying to rise. [ "I already broke the gate and the teahouse. You’re just here for the cleanup." ]

[ "I'm here for the bounty," ] the hunter replied, their voice masked by a distorted, metallic filter. [ "And I don't care how much you weigh. My blades are tuned to vibrate at the resonant frequency of your internal frame. I’m going to disassemble you, joint by joint." ]

Gen leaned over to Kaito, whispering behind his hand, [ "That’s a Kinetic Carver. If they touch you, you won't just break; you’ll turn into a pile of loose rivets. We need a trap." ]

[ "I'm an iron man, Gen. I am the trap." ]

[ "No, you’re an idiot," ] Gen hissed. [ "The floorboards in the far corner—the ones I loosened for the ore shipment? Lure them there." ]

Kaito stood, his movements jerky and loud, his armor scraping against itself. [ "Hey, masked moron! You want a trophy? Come and get it. But I should warn you, my floor-manners are terrible." ]

The hunter lunged, a blur of motion. Kaito swung his massive arm, but the hunter ducked, their blades carving a shallow trench into Kaito’s side. Sparks showered the room like fireworks.

[ "Missed," ] Kaito taunted, backing toward the corner. [ "Is that the best you’ve got? My grandma hits harder than that, and she’s been dead for twenty years!" ]

[ "You talk a lot for a pile of scrap," ] the hunter snarled, closing the distance with terrifying speed.

Kaito planted his feet, feeling the wooden floor sag under his immense density. As the hunter leaped, aiming for his neck, Kaito didn't try to block. He simply collapsed, throwing his entire three-hundred-pound frame onto the floorboards.

CRACK-THOOM.*

The floor gave way instantly, dropping the hunter into the pitch-black storage pit below, right onto the jagged, rusted spikes Gen had prepared for the ore. A sickening crunch echoed upward.

[ "Is... is he dead?" ] Gen asked, holding his lamp over the hole.

[ "He's definitely not dancing," ] Kaito grunted, hauling himself back to his feet and staring into the darkness.

The hunter lay at the bottom, blades scattered, mask cracked. They wheezed, a pathetic, gurgling sound. [ "You... you were supposed to be... an easy score." ]

[ "Who sent you?" ] Kaito demanded, leaning over the ledge. [ "Hidetada is already dealt with." ]

The hunter laughed, a dry, rattling sound. [ "Hidetada? That incompetent fool? He was just the bait. Lord Katsumoto is the one who wanted your 'special' frame. He’s been tracking your magnetic signature since you left the forest. He knows you’re not just a man in a shell, Kaito. He knows you’re the first of a new, cursed breed." ]

Kaito felt a chill that had nothing to do with the night air. [ "A new breed?" ]

[ "The Shogun doesn't care about revenge," ] the hunter gasped, their eyes fading. [ "He cares about the blueprint inside your chest. You aren't just an assassin, you iron-gut... you’re the prototype for an army." ]

The hunter slumped, silence reclaiming the room.

Gen looked at Kaito, his single eye wide with realization. [ "Well, Kaito. It looks like you didn't end a war. You just started a catalog search." ]

Kaito stared at his iron hand, the rivets straining. [ "I think I need a bigger hammer, Gen." ]

[ "You need more than a hammer," ] Gen said, looking at the door, then back at the giant, metallic man. [ "You need a miracle. Or at least a lot more oil." ]
