Reincarnated In Attack On Titan World As Nobody

Inside the chief instructor's office at the training corps base, the air was thick with silence. Shin stood alone before Erwin Smith, the tall, imposing deputy commander of the Survey Corps, who sat behind the desk, arms folded, studying the boy with unreadable calm.

The dim lamplight cast long shadows across the room's wooden interior. Outside the window, the wind howled faintly against the walls, but inside, not a word had been exchanged yet.

Shin showed no signs of fear. His posture was relaxed, almost casual, his eyes unwavering as he met Erwin's gaze. There was no guilt in his expression—because, from his perspective, he had done nothing wrong.

He had been ambushed. Surrounded. Targeted.

All he did was fight back.

And if the outcome had tilted heavily in his favor, that wasn't his fault. It was just a matter of strength.

Still, what gnawed at him wasn't the scolding he might receive—it was the timing. If Erwin had shown up just ten minutes later, Shin might have completed the system task and earned that coveted stat reward.

He sighed inwardly, lamenting the lost opportunity.

Erwin, for his part, was watching the boy closely. The lack of anxiety or remorse in Shin's demeanor only confirmed what he had already begun to suspect—this boy was a wild card. A potential asset, yes. But also a potential headache.

"You caused quite a stir today," Erwin finally said, his voice calm, his tone neither accusing nor lenient. "Do you understand the implications of your actions?"

Shin met his eyes. "I was attacked first. They blocked my path, surrounded me, and instigated the fight. I only defended myself." His tone was level, but there was a flicker of defiance beneath the surface. "If anything, they should be the ones questioned."

Erwin raised an eyebrow slightly, intrigued. The boy wasn't just fearless—he was assertive, confident in both his strength and his justification.

"You seem very sure of yourself," Erwin said, folding his hands on the table. "Not many people can stand where you are and speak so directly."

Shin smirked faintly. "It helps to have backup," he replied. "And in this case… that backup was myself."

That made Erwin chuckle softly, though the amusement didn't quite reach his eyes. "Is that so?"

Shin nodded. "I'm not looking to cause trouble, but I won't be trampled on either. If anyone else had been in my shoes tonight, they'd have been overwhelmed and humiliated. I fought back—and I think I did what anyone should've done."

Erwin leaned back in his chair, quiet for a long moment. "And you assumed," he said finally, "that I wouldn't punish you."

It wasn't a question.

"I did," Shin admitted without flinching.

"And what gave you that confidence?"

"Because you're Erwin Smith," Shin said simply. "You don't strike me as someone who throws away talent over protocol. You're a commander, not a bureaucrat."

That made Erwin sit forward slightly. The boy had just called his bluff—but with an insight that impressed him more than it irritated him.

"You're bold," Erwin said, his voice sharpening just slightly. "And you believe you're strong enough to warrant tolerance?"

Shin's eyes burned with a quiet intensity. "I don't believe it. I know it. My strength can match—or exceed—every other recruit this year."

There was no arrogance in his tone, only certainty. He wasn't bragging. He was stating a fact.

Erwin studied him carefully. This wasn't just bravado. The boy believed what he said—and if the reports were anything to go by, he had reason to.

Still, this kind of attitude could be dangerous.

"And what is it you want?" Erwin asked. "Surely you didn't fight twenty-six recruits just to make a point."

Shin didn't hesitate. "I want to graduate early."

The air in the room seemed to grow heavier at those words.

Erwin didn't respond immediately. He stared at the boy across from him, his eyes cool and thoughtful. "You understand what you're asking," he said at last. "Recruits undergo three full years of training for a reason. We don't hand out early graduation lightly."

"I understand," Shin said. "But I'm not like the others. I already have the foundations—physically and mentally. I don't need three years to be ready. What I need… is the chance to prove that."

He wasn't lying. With his system's support and his enhanced abilities, he could replicate the equivalent of a year's worth of training in weeks. His stats were already beginning to pull away from his peers. He couldn't afford to waste time—not with 845 looming.

Three years in the training corps would be a luxury he didn't have.

Erwin remained silent, eyes narrowed ever so slightly. His fingers tapped the edge of the desk. Shin's words weren't unfamiliar. Many overconfident recruits had claimed the same in the past.

But this one was different.

There was calculation in his words, not desperation. Not pride. A measured, strategic mind behind his eyes.

Finally, Erwin stood tall and commanding. His expression grew more serious.

"Training in the corps is not just about physical strength," he said. "It's about discipline. Mastery. Teamwork. Coordination. You may be strong now, but that doesn't mean you'll survive outside these walls."

Shin remained silent, respectful, listening.

"But," Erwin continued, "if you truly believe you can meet the standard required of a graduate—if you can master the entire curriculum faster than your peers—then I won't stand in your way."

Shin's eyes lit up, and Erwin raised a cautioning hand.

"My expectations," he said, "will not be lowered. You'll need to meet every benchmark: mobility, hand-to-hand combat, vertical maneuvering, tactical knowledge, survival techniques. If you fail even one, you return to the regular training schedule."

"I understand," Shin replied. "But I won't fail."

Erwin smiled faintly. "Good. Confidence is admirable. But remember—too much of it becomes arrogance."

"I won't make that mistake," Shin replied calmly.

For a moment, the two stood in silence again—commander and recruit, predator and predator, neither one flinching under the other's gaze.

Finally, Erwin nodded.

"I'll speak with the other instructors. From tomorrow onward, you'll begin your assessment trials. You'll be held to the highest standard. Prove that you can match it, and I'll personally recommend your early enlistment."

Shin exhaled slowly, the weight of tension slipping off his shoulders.

"Thank you, sir. I won't let you down."

Erwin waved him off. "You're dismissed."

Shin saluted crisply and turned to leave. As he stepped out into the dark hallway, he clenched his fists slightly, the determination in his chest hardening into something stronger—resolve.

Three months.

That's all he needed.

Three months to master every skill, crush every expectation, and join the Survey Corps ahead of schedule.

If he was going to change the fate of this world, then he needed to start now, while he still had the edge.
