Attack on Titan: The Strongest Newcomer

"I am your instructor, Keith Shadis! Listen up, you little brats! This is the Training Corps, and you..."

The imposing instructor scanned the training ground, his voice booming like thunder.

"You, the future rations for the Titans, will train here for three years! Listen carefully—there are 282 recruits in the 104th Cadet Corps. I don't know how many of you will graduate, but mark my words—it won't be easy. When the time comes to face Titans in battle, what awaits you will be ten or even a hundred times more brutal than anything you can imagine!"

Keith's words struck like a hammer, leaving an ominous silence.

Ryo Carter stood amidst the recruits, the noise of the instructor's voice buzzing in his ears. He had only been in this world for a few days, yet everything about it felt surreal and chaotic.

Ryo sighed inwardly, his gaze drifting to the others. There was Mikasa Ackerman, her signature red scarf wrapped around her neck; Eren Yaeger, his fiery determination evident in his stance; and Armin Arlert, who seemed lost in thought. Among the 104th Cadet Corps, the presence of these familiar faces brought a strange sense of comfort to Ryo.

As much as he hated to admit it, he had indeed traveled to the world of *Attack on Titan*!

This world was perilous, fraught with dangers, and survival was a battle in itself. Between the Titans, the oppressive church, and the complexities of human conflict, there was no place for the weak.

"If I want to survive in this chaos, I must grow stronger," Ryo thought resolutely. "I need to become someone like Captain Levi—or even stronger!"

"Hey, kid in the first row! What are you daydreaming about? Can't you hear me calling your name?"

Keith Shadis's sharp rebuke jolted Ryo out of his thoughts, dragging him back to the harsh reality of the training ground.

"Ah? Instructor, what can I do for you?"

Straightening his posture, Ryo quickly stood at attention. In the Training Corps, the instructor's word was law.

"Cadet Ryo Carter, explain why you were in a daze on my training ground!"

Keith marched toward him, the whip in his hand making Ryo's heart race. He knew if that whip struck him, it wouldn't be pretty.

"I was thinking about how to get stronger, sir!" Ryo responded, his voice steady as he stood tall.

"Stronger? And why do you want to get stronger?"

Keith's icy gaze bore into him, his presence radiating authority.

"To protect the people I care about, sir!" Ryo declared confidently.

Keith's expression softened slightly, as if he found Ryo's words commendable. He clapped a hand on Ryo's shoulder, startling him.

"The people you care about... are they your family?"

Before he could stop himself, Ryo blurted out, "No, sir! I want to protect Mikasa and Krista!"

A ripple of shock spread across the training ground. Eren and Armin turned to Mikasa in disbelief, while Krista blushed furiously. The instructor's face twisted with barely-contained irritation, veins visibly throbbing on his forehead.

"Very well!" Keith bellowed. "You want to prove your strength? Run fifty laps around the training ground—NOW!"

The sneer on Keith's face showed he wasn't done. "And to make things interesting… Mikasa Ackerman! Krista Lenz! Step forward!"

Ryo froze. He couldn't understand why Keith had called them out. Mikasa and Krista, equally confused, hesitated before stepping out of line.

"You two will accompany him!" Keith barked. "Fifty laps each! None of you are eating lunch until you're done!"

Ryo's heart sank as Mikasa's cold gaze fell on him. She looked annoyed, clearly unimpressed at being dragged into this. Krista, on the other hand, seemed more nervous than angry, her face flushed as she avoided eye contact.

Ryo cursed inwardly. His reckless words had landed them all in trouble.

"Instructor, I'll take full responsibility!" Ryo shouted. "Please let Mikasa and Krista go! I'll run all 150 laps myself!"

The training ground erupted into murmurs.

"Is this guy insane?" Armin whispered to Eren, who nodded in agreement.

Even Keith seemed momentarily surprised. But his sneer soon returned.

"Very well, Carter," he said. "You want to be a hero? Fine. 150 laps it is! And don't even think about lunch until you're finished!"

Ryo nodded without hesitation. "Understood, sir. Can I start now?"

Keith glanced at his stopwatch and gave a curt nod.

A small smile played on Ryo's lips. He wasn't speaking to Keith anymore.

"Ding! System prompt: Two-hour timer activated. Completing this task will reward you with a novice growth gift pack."
