Reincarnated In Attack On Titan World As Nobody

Unconsciously, Lock had already spent more than a month inside the Training Corps. Every day blurred into the next — dawn drills, hours of exercises, bruises, aching muscles — and yet, day by day, his body grew sharper, his instincts cleaner, his control steadier.

Through relentless work, he had already mastered nearly every subject in the curriculum. Some more thoroughly than others, of course. His equestrian form was solid, his tactical theory sound, but where he excelled most was with the omnidirectional mobility gear. His coordination was exceptional; every anchor line and gas burst was controlled with precision. Even Klaus, their instructor, struggled to find fault when Lock was in the air.

But all of this was still training. Wooden dummies, fixed scenarios, carefully measured exercises. Real battle was something else entirely. Giants were not predictable. They were fast, cruel, and chaotic. Only adaptability would decide whether you lived or died.

At that moment, Lock was in the midst of a simulated combat assessment.

"Pssshhh—!"

Compressed air hissed as his gear fired, cables singing. Lock flew through the lattice of trees, eyes sharp, scanning every angle of the forest. The black bamboo practice swords in his hands caught the light, blades poised.

The target would appear without warning.

And he had only one chance.

Lock's breathing was calm despite the tension. He kept his body light, twisting between trunks, measuring his speed so as not to exhaust himself too quickly. Every nerve in him was awake. He knew this wasn't just a test of skill — Klaus wanted to test his patience.

Then, without warning, a massive wooden figure lunged from the foliage ahead.

Lock didn't flinch. His waist and leg harnesses flexed as he pulled the trigger, redirecting himself with sharp precision. He soared over the figure's head, body folding gracefully midair, and with a swift reverse grip, carved his blade across the back of its neck.

The cut was clean. The wooden titan's head tumbled, rolling through the grass.

Lock didn't stop to celebrate. He fired another line, propelled himself higher, scanning. The real test was never over after the first strike.

His instincts were right. From the shadows of a nearby trunk, a second target burst free — a giant head carved from wood, hurtling at him.

In an instant, Lock twisted in midair, core muscles straining as he forced a change of trajectory. His trigger clicked, cable burying itself into a tree behind the target. His body snapped forward like an arrow.

Both blades crossed in reverse grip. He spun as he passed, his movement a blur.

"Shhhhk—!"

The wooden head fell in two, crashing with a muffled thud against the dirt.

Lock landed against the bark of a trunk, crouched sideways with one line still anchored. His face betrayed no excitement, no pride — as though what he'd just done was expected, not extraordinary.

The forest broke into applause.

"Clap—clap—clap—"

Klaus stepped out from behind a tree, the rest of the recruits trailing him. Their faces were split between shock and admiration.

"Excellent kill," Klaus said, voice tinged with genuine respect.

Lock slid down to the ground, steady on his feet. "They're just wooden models," he answered simply. "They don't fight back."

The words carried no arrogance, just plain truth. Training would never equal battle. The history of the Corps was proof enough — graduates who could execute perfect strikes in camp, only to be torn apart in the field.

That realism, that refusal to get carried away, only deepened Klaus's appreciation. This boy wasn't just gifted — he was grounded.

Behind him, the recruits whispered among themselves. Some of them had clashed with Lock before, jealous of his aloofness, irritated by his attitude. But after watching his movements, all of that dissolved. His technique was too sharp to deny.

Even the girls in the group couldn't hide the stars in their eyes as they watched him.

Lock ignored it all. He looked only at Klaus, voice even but firm.

"Instructor. At this level… can I graduate?"

Klaus blinked, surprised but not entirely unprepared. He had noticed it for days now — Lock had plateaued. The boy had grown faster than anyone he had ever seen, but here, within these walls, his improvement was slowing. He no longer had equals to test himself against. Levi had stopped visiting, and Jonah — once his toughest sparring partner — could barely stand three exchanges before being defeated.

Lock had outgrown the camp.

But Klaus still hesitated. He studied the boy in front of him, no older than fourteen. "Lock," he said carefully, "with your scores, you could have graduated long ago. But are you certain? You're still a child. If you stay two more years, you'll leave with more experience, more time to prepare. Once you graduate… There is no safety. Out there is only the battlefield."

There was concern in his tone, concern he rarely allowed himself to show. He had sent many young soldiers to the Corps before, and too many of them had never returned.

Lock felt it, and for a brief moment, he allowed himself to be grateful. But his answer did not change. His eyes burned with quiet conviction.

"I've thought it through. I want to join the Survey Corps. I want to see the world beyond the Walls. I want to uncover the truth about the Titans. And I want to dedicate myself to humanity's freedom."

He placed his fist over his chest and struck it hard against his heart.

The sound echoed.

Klaus inhaled deeply. For a long time, he said nothing, staring at this boy who carried himself like a soldier twice his age. Finally, he nodded.

"…Very well. Lock, I approve your application for early graduation. You will stand first in this year's class. That gives you priority in choosing your corps. And though I already know the answer, I'll ask you one last time — where will you go?"

Lock didn't hesitate. His voice was sharp, resolute.

"Survey Corps!"
