Iron bone

The forest floor was a tapestry of drying blood and jagged steel. Kaito’s breath rattled in his chest, a wet, bubbling sound as seven iron-tipped spears held him pinned to the ancient cedar. His vision blurred, painting the world in shades of crimson and twilight grey. He could hear the low, hungry growls of the wolves circling the clearing, their eyes glinting like embers in the dark.

“To think,” Kaito wheezed, blood flecking his cracked lips, “that I served these bastards for a decade.”

He didn’t die. The cold settled into his marrow, but the life refused to leave. When the wolves lunged, they didn't find a meal; they found the shadow of a man who wouldn't be finished. Then, darkness consumed him.

Kaito woke to the rhythmic, suffocating clink-thud of a hammer against an anvil. He tried to sit up, but his shoulder didn't just move—it shrieked. It was a high-pitched, grinding sound of rusted hinges protesting against a rusted frame.

"Easy, you pile of scrap metal," a gravelly voice echoed.

Kaito’s head snapped toward the corner of the dim hut. Grandpa Gen sat there, nursing a bowl of bitter tea, his single eye darting over Kaito’s form with unamused scrutiny.

"Gen? What… what did you do to me?" Kaito rasped. His voice sounded like gravel shifting in a tin bucket.

[ "I did you a favor, you ungrateful bucket of bolts. You were practically sushi for those forest mutts when I dragged you in here," ] Gen grunted, setting his tea down with a shaky hand. [ "I had to use the leftover scrap from the Shogun’s supply train to patch your sorry hide. Your bones were shattered like cheap pottery. Now, they’re reinforced iron. High-grade, mind you." ]

Kaito tried to lift his arm. It rose with the grace of a trebuchet, jerky and terrifyingly heavy. He stared at his hand. Instead of flesh, there was a matte-grey plating of iron, held together by rivets that looked like they were forged in a thunderstorm.

"This is… this is insane," Kaito groaned. He tried to pivot his hips to stand, but his internal mechanics jammed. His torso jerked violently, sending him crashing face-first into the wooden floorboards. The impact didn't hurt, but the sound was like a car wreck in a cutlery factory—a loud, resonant BANG-CLANG-SCRITCH.

[ "Look at you," ] Gen cackled, clutching his stomach as he rocked back and forth. [ "A legendary warrior reduced to a falling toaster. You move like a malfunctioning puppet, Kaito. It’s pathetic. If you tried to dance, you’d probably decapitate yourself with your own elbow." ]

"Shut up, old man," Kaito growled, sparks flying from his neck joint as he struggled to find leverage. He shoved his palm against the floor, but he overcalculated the force; his fingers punched clean through the thick oak planks, pinning his hand to the subfloor. [ "Give me a hand here! My grip strength is a nightmare!" ]

[ "No way," ] Gen wiped a tear of laughter from his eye. [ "I want to see if you can solve this without breaking the floorboards again. Maybe you should try thinking before you move? Your brain is still human, but your body is a walking fortress now. Treat it like one." ]

Kaito exhaled, a hiss of steam venting from his shoulder vents. He closed his eyes, centering his focus. He stopped trying to move his arm like a limb and started imagining it as a lever. He pulled. With a groan of tortured metal, the floorboard splintered, and he ripped his hand free, standing up with a wobbling, metallic gait.

[ "There! You’re standing!" ] Gen clapped his hands mockingly. [ "Bravo! A three-hundred-pound iron man takes his first steps toward a cliff. What’s the plan, iron-gut? Going to challenge the Shogun to a duel and rust to death?" ]

"Hidetada," Kaito hissed, the name tasting like copper. "He was the one who ordered the spears. He wanted me to suffer. He thought I was just a disposable tool. Well, tools don't usually walk back from the grave."

[ "You’re going to get yourself scrapped in an hour," ] Gen countered, though his smile faded into a look of cynical concern. [ "You’re a glorified suit of armor without a manual. You’ll trip over a pebble and sink into the earth." ]

"I don't care," Kaito said, grabbing a wooden staff from the wall. He slammed it onto the ground, finding that the vibration didn't rattle his teeth anymore. It was solid. Unyielding. [ "The pain of the metal grating against my bones… it’s there, but it’s distant. I don't feel the fatigue. I don't feel the hunger. I feel… heavy. And that weight is going to be Hidetada’s end." ]

[ "You're delusional," ] Gen sighed, shaking his head. [ "But at least you'll be the loudest corpse in the graveyard. If you’re really going, take the long way. Don’t go crashing through the villages—you’ll look like a giant tin can having a seizure." ]

"I’m not looking for stealth, Gen. I’m looking for an apology," Kaito gritted out. He marched toward the door, each step sounding like a sledgehammer hitting a rail track. CLANK-CLANK-CLANK. Every movement was a struggle of calibration, his joints locking and unlocking with agonizing mechanical friction.

[ "You’re really going to walk all the way there?" ] Gen asked, shouting over the metallic clamor of Kaito’s departure. [ "The gate of the outpost is heavy timber! You’ll probably just get stuck in the mud!" ]

"Then I'll use the gate as a toothpick!" Kaito shouted back, not looking behind him.

The journey was a masterclass in frustration. Twice, Kaito’s knee seized up mid-stride, causing him to face-plant into the dirt, leaving a crater-like indentation where his face hit the soil. Each time, he simply stood back up, his body ignoring the impact that would have shattered a normal man’s skull. He began to realize the truth: he wasn't just a man in a shell. He was a weapon that had forgotten it was human.

Hours later, the silhouette of Lord Hidetada’s outpost rose against the moonlit horizon. It was a formidable structure of reinforced cedar and iron bars, a symbol of the man who had betrayed him.

Kaito reached the gate. His internal balance was still wildly erratic, his metallic weight pulling him forward with every shift of his center of gravity. As he stepped onto the drawbridge, his left foot snagged on a rogue nail.

[ "Oh, for the love of—" ] Kaito cursed as gravity seized control.

He didn't stumble; he plummeted. His body, dense and unstoppable, collided with the wooden gate with the force of a falling boulder. There was a sound like a thunderclap—a sickening, glorious CRUNCH* of splintering timber and snapping hinges. The entire gate folded inward like parchment, and Kaito skidded across the muddy courtyard, his metallic face plating carving a trench into the ground until he finally came to a halt in the center of the training yard.

The guards surrounding the campfire froze. Silence descended on the outpost, interrupted only by the sound of Kaito’s internal cooling system whirring and the steam hissing from his joints.

Kaito slowly stood, his heavy armor shedding splinters of the shattered gate like confetti. He turned his head, the neck joints shrieking in the silence.

[ "Evening," ] Kaito rumbled, his voice echoing with a hollow, synthetic resonance that sent the guards scrambling for their swords. [ "I believe I’m here for an appointment with Lord Hidetada. And I don’t think I’m going to be paying the entry f*e." ]
