Reborn as the Villainous Noble, Dodging the Sissy Ending—But My Stepbrother’s Yandere Love Turns Him into the Final Boss

Whoooosh— 

The wind roared. 

The luxurious window frame, trimmed with gold, trembled subtly as white lace curtains billowed like triumphant flags. 

A sudden gust swept into the room, snuffing out the candle flames, leaving only the cold, pale light of the full moon casting shadows across the floor. 

This was a corner of the royal castle—normally, any strange noise would have summoned the guards immediately. 

But the corridor outside remained utterly silent, with no sign of anyone. 

As I glanced around, I saw Reginald lying collapsed on the floor, his shoulders rising and falling just slightly. 

He’s alive. That alone brought a wave of relief washing through me. 

And now, in this room, the only ones still conscious were me… and him. 

Given this unnatural stillness and the bizarre situation, it didn’t take much to guess who had caused it. 

But—my mind couldn’t catch up. 

“…Why are you here?” 

Looking up at the figure before me, I felt no fear. 

Only confusion bloomed in my chest, spreading wider with every breath. 

Why him? Why here, in the royal castle? And in such a dramatic fashion—? 

As far as I knew, nothing like this was ever supposed to happen. 

In response to my question, he simply reached out his hand. 

And with a breathtakingly beautiful smile, he said: 

“I came to get you.”

Isekai reincarnation. 

Just hearing the words, most people today would probably know what it means. 

It’s become such a common theme—appearing in games, anime, and novels alike. 

As someone who loves books and light novels, it never felt like a distant fantasy. 

Being reborn, fighting battles, falling in love… I’d followed that kind of story countless times. 

So I thought I “understood” what it meant. 

I thought I could more or less predict what would happen. 

—But. 

Who in the world actually expects it to happen to them? 

Back in my original life, I was just an ordinary university student in Japan. 

Not exceptionally brilliant, not a total slacker—just average. I worked part-time as a private tutor and attended a normal university. 

I didn’t have a girlfriend, but I had close friends, and my campus life was pretty relaxed overall. 

Then, one night, my little sister asked me to play a console game with her. 

It was called “Noël.” 

…My sister and I get along fairly well. We both share some nerdy interests, so it wasn’t that unusual for her to invite me to play a game. 

“Noël” had originally started as a doujin (indie) project, so the story wasn’t all that groundbreaking—but the character art and event CGs were stunning, and the voice acting was said to be on a whole other level. Eventually, it had been released as a commercial title. 

And yeah—just watching her play, the visuals were gorgeous. The voices, amazing. 

The gameplay was your standard otome game: you play as the protagonist, interact with handsome male characters, make choices, deepen relationships. 

There were a few minigames, but nothing too difficult—seemed pretty accessible even to casual gamers. 

…But there was a catch. 

If you chose the wrong option in this game, things could get really bad. 

One little slip-up and the protagonist—sometimes even the enemies—would instantly end up in “feminized submission” endings. 

We’re talking mob gangbangs, breeding pits, sex slave routes, brothel bad ends… 

I seriously wanted to ask, “Are you sure this is for general audiences!?” 

My sister, ever cheerful, said, “The failure routes are the best part!” and played them with disturbing glee. 

I, on the other hand, was downright traumatized. 

The voice acting was too good—too realistic. 

Your big brother can’t handle this. 

—Oh, and by the way, this game? 

It’s BL. 

Sis. 

Why. 

Why did you think playing a BL game with your older brother was a good idea…? 

Big bro doesn’t get it. 

Sure, the art was beautiful. The story was decadent and dramatic. The characters were undeniably attractive. 

But the romance—and the violation—that unfolded in that world was just way too intense for me! 

…And now, if you’ve read this far, you might already know what I’m about to say. 

Earlier, I said I’d been reincarnated into another world. 

That’s right. 

Believe it or not— 

I was reincarnated into the BL game “Noël.”
