I Became a Knight in the Reverse World
The world was not equal.
That was the first thing I realized after reincarnating into this strange new life.
In my previous world, men were generally stronger. We had the physical advantage in most fields, and society reflected that. But here? Everything was flipped.
Women possessed overwhelmingly superior mana. From birth, they could wield power that made men look like fragile twigs in comparison. The blessings of the Goddesses had seen to that. While men rarely possessed any usable mana at all.
Knights? Those were almost exclusively women. The very idea of a male knight was treated like a bad joke.
“A man becoming a knight? Don’t make me laugh.”
“Why don’t you just marry into a good family instead?”
I’d heard those lines more times than I could count. And every single time, they lit a fire in my chest.
My name is Ruines. In this world, I was born the youngest son of a minor noble family. My two older sisters were both talented aura users—women who could swing a sword wrapped in blazing mana and cut down monsters three times their size. Meanwhile, I could barely lift a training blade without my arms shaking.
But I refused to accept it.
If this world said men couldn’t be knights, then I would just have to become the exception that proved them wrong.
That determination started when I was eight years old. I still remember the exact moment. My eldest sister, proud and tall in her newly polished knight’s armor, had just returned from subjugating a band of goblins. The whole family gathered to celebrate her achievement. Everyone praised her. Everyone looked at her with admiration.
And then someone glanced at me—the scrawny little brother hiding behind our mother’s skirt—and laughed.
“Ruines will probably end up as some lady’s house husband, right?”
The words were said in jest, but they carved themselves into my heart like a branding iron.
From that day forward, I trained like a madman.
While the girls my age were learning proper aura control and elegant sword forms, I was out behind the manor doing push-ups until my arms gave out. I ran until my lungs burned. I swung a wooden sword until my palms bled. I studied every knightly manual I could get my hands on, even the ones written exclusively for women. I adapted what I could.
Because in this world, men had almost no mana. That meant I couldn’t rely on the same techniques. I had to find another way. I had to forge my body into a weapon that didn’t need to depend on magical reinforcement.
It was brutal. There were days I wanted to quit. Nights when the pain in my muscles kept me awake and the mocking voices in my head grew louder than my own resolve.
But every time I felt like giving up, I remembered that laughter. I remembered the casual dismissal in everyone’s eyes when they looked at me.
So I kept going.
Years passed. My body changed. What was once a frail, delicate frame slowly transformed through relentless effort. My shoulders broadened. My arms grew corded with muscle. My legs became powerful springs capable of explosive movement. I wasn’t as strong as the female knights who could wrap themselves in aura, but I was faster. More precise. I learned to read an opponent’s movements like a book and strike before they could bring their superior power to bear.
At sixteen, I finally earned the right to take the knight’s examination.
The testing grounds were packed. Mostly young women in gleaming armor, their mana signatures blazing like bonfires. A few curious onlookers had gathered, drawn by the rumor that a boy had dared to show up.
I could feel their eyes on me as I stepped onto the field. Whispers rippled through the crowd.
“Is that him? The male applicant?”
“This has to be a prank.”
“Poor kid. He’s going to get crushed.”
The examiner, a stern-faced female knight with silver hair, looked me up and down with open skepticism.
“State your name and purpose.”
I met her gaze without flinching.
“Ruines von Aster. I am here to become a knight.”
A ripple of laughter swept through the spectators. Even some of the other examinees smirked.
The examiner raised an eyebrow. “You understand that this test involves live combat against a knight-ranked opponent, yes? We do not make exceptions for gender. If you step into that ring, you will be treated as any other candidate.”
“I understand.”
She studied me for a long moment, then shrugged. “Very well. Let’s see what you’ve got, boy.”
My opponent was a woman named Lydia. Twenty-two years old. Already a full-fledged knight with three years of border patrol experience under her belt. She stepped into the arena carrying a longsword that looked like it weighed more than I did. Her aura flickered around her like golden flames.
She gave me a pitying look.
“I’ll try not to break anything important. Just surrender quickly, alright?”
I didn’t answer. I simply raised my own blade—a lighter, faster sword I’d had specially commissioned—and settled into a stance I had perfected over years of solitary training.
The examiner called the start of the match.
Lydia moved first. She was fast—faster than anyone I’d ever faced. Her sword came down in a blazing arc of aura that could have split a boulder in two.
But I wasn’t where she expected me to be.
I had already slipped inside her reach, using the explosive power of my legs to close the distance in a single heartbeat. My blade flicked out—once, twice, three times—targeting the gaps in her defense that her overwhelming mana made her overlook.
She staggered back, eyes wide with surprise.
“What…?”
I didn’t let up. I pressed the attack, forcing her to retreat, making her waste her aura on wild swings while I conserved every ounce of my strength. My breathing stayed steady. My movements remained economical. Every strike was calculated to maximize damage while minimizing exposure.
The crowd had gone silent.
Lydia’s face twisted with frustration. She poured more mana into her aura, turning her sword into a blazing comet. But the more power she used, the sloppier her form became. She was relying on raw strength instead of technique.
That was her mistake.
I saw the opening and took it.
My sword slipped past her guard and tapped lightly against the side of her neck—just hard enough to register as a clean hit.
The examiner’s voice rang out across the arena.
Winner: Ruines von Aster
The silence that followed was deafening.
Then the arena exploded with noise.
“No way…”
“He actually beat a knight?!”
“That wasn’t luck. Did you see his footwork?”
Lydia stared at me, her face flushed with a mixture of shock and something that looked almost like respect. She lowered her sword and gave me a small, reluctant nod.
“...Not bad, kid. You’ve got some crazy skills.”
The examiner approached, her expression unreadable. For a long moment she simply looked at me. Then, to my complete surprise, she smiled.
“Congratulations, Ruines von Aster. You have passed the knight examination. From this day forward, you are officially recognized as a knight of the kingdom.”
She raised her voice so the entire crowd could hear.
“Let it be known that on this day, a man has become a knight through his own power and determination. Let no one ever say again that it cannot be done.”
The cheers that rose up were hesitant at first. Then they grew. And grew. Until the entire testing ground was roaring with applause.
I stood there, chest heaving, sword still in hand, feeling something I hadn’t felt in a very long time.
Validation.
But even as the cheers washed over me, I knew this was only the beginning. Becoming a knight was one thing. Being accepted as one—truly accepted—was going to be another battle entirely.
And somewhere in the crowd, I caught sight of a familiar face watching me with wide, astonished eyes.
My childhood friend.
The girl who had once promised to marry me if I ever managed to become a proper knight.
She was smiling now. Smiling in a way that made my heart do something complicated in my chest.
I smiled back.
This was going to be interesting.
