I Want to Completely Avoid Troubled Girls, but It Seems I’ve Reincarnated as a Background Character in the Most Dangerous Yandere Academy

Chapter 10: The Bloodstained Blade Satsuki (Satsuki’s Side)

I placed the knife in my bag. Once I was ready, I contacted Issei-kun.

My ritual was almost complete. Taking a life was just a procedural task—a mere appetizer.

The act of taking a life itself wasn’t my goal. My true aim was to make Issei-kun mine and mine alone.

As long as I could achieve that, nothing else mattered.

I’m fully aware of how twisted I’ve become. That I, Issei-kun’s girlfriend, would lose faith in him and wish to end everything… It’s absurd.

Right now, I’m unstoppable. Laws, order—none of it concerns me.

I’ll think about everything after it’s all over. All I can do is pray that a future exists “beyond that point.”

I’ve thought about the gap between ideals and reality countless times.

When I realized I couldn’t bring reality closer to my ideals, I arrived at a single conclusion.

—If I couldn’t change reality, I would bury myself in an ideal world instead.

To do so, I needed to “abandon” reality. I had to steel myself with unwavering resolve.

In exchange for that precarious balance, I found a swift way to create a world for just me and Issei-kun.

I would push Issei-kun to the “next stage.”

In other words, I would take Issei-kun’s life—his soul—for myself.

If I took his life, I could capture his vanishing soul, holding it in my hands before it dissolved into the air. That’s what I believe.

Will Issei-kun accept my noble ideals? Honestly, I don’t know.

To sacrifice one’s life for an ideal requires extraordinary conviction.

I can’t say for sure that Issei-kun is such a devoted believer. To be frank, it’s likely a painful ending for him.

I know it’s a forceful approach. But I have no other choice. This is all I have left.

…It’s time to leave the house.

The journey to school was over in no time.

Now, the real challenge begins.

Evading the guards was easy. Of course, I had memorized their patrol routes and the blind spots of the security cameras beforehand.

I had also prepared spare keys by taking impressions of every lock on campus. The school’s security measures are laughably lax.

I moved swiftly and smoothly, making my way onto the rooftop.

The night breeze was cool and refreshing.

I opened my bag and took out two knives. Gripping one in each hand, I raised the blades to the night sky. The reflected light glimmered beautifully.

The moon is out tonight. A fitting day for the plan to unfold.

Once I proceed, there’s no going back to peaceful days. I will have derailed completely from the tracks of humanity.

But I’m resolved, so there’s no hesitation. No lingering doubts to make me reconsider.

Until Issei-kun arrives, I’ll rehearse.

What should I say to him in our final moments? What motions should I use to strike? How should I clean up afterward?

I’ve visualized it all in vivid detail. I’ve anticipated most of Issei-kun’s likely objections and prepared my responses. I’ve rehearsed the motions countless times.

Once everything was ready, I took a deep breath.

—It wasn’t a bad life, I thought.

It’s a shame I couldn’t be with my precious Issei-kun. But my wishes will surely be fulfilled. So I’m not afraid.

They say a strong will can make the impossible possible. That’s why I’ll gamble, even if the chances are slim.

I believe there’s a utopia somewhere, and I’ll reach it someday.

Closing my eyes, I felt the night wind. It was comforting, as though I had become the wind itself.

The sound of the rooftop door creaking open snapped me out of my meditative state.

“You’re here, Satsu—”

Issei-kun, who had arrived, immediately noticed something was off about me.

“I’ve been waiting for you, Issei-kun. I came to give you a surprise today.”

“A surprise? Calling me to school at night, with knives in both hands?”

Issei-kun’s wariness was rising. Naturally, he couldn’t have a calm conversation with someone holding knives in both hands.

I let the knife in my left hand drop to the ground.

“Put down the knife in your right hand too.”

“No. I need this.”

“I’ve felt bad for a long time. I confessed to you first, but then I got scared of understanding you, Satsuki, and I desperately tried to avoid you recently.”

“Yes, that’s true.”

“I want to start over. Like we were at the beginning, nurturing small joys together, treasuring them.”

No. That’s not my wish.

What I sought in Issei-kun was to fill the void I couldn’t fill on my own. For us to complete each other, becoming two halves of one whole.

That’s why frequent contact and constraints were necessary. Issei-kun should have accepted us as inseparable, as one.

“…Why don’t you understand me, Issei-kun? I believed you would.”

Hearing, I thought I did, was no consolation.

“‘Thinking’ isn’t enough. If you don’t believe in me from the bottom of your heart, it’s meaningless.”

When he began to offer his sincerest apologies, I interrupted. Those were the words he always used to cover up lies.

Empty words meant to smooth things over are meaningless.

What’s done is done. There’s no going back.

His arguments were all within my expectations. In the end, he didn’t understand. It’s disappointing.

At last, I can find happiness. Issei-kun will go to the other world—the next stage.

“Goodbye, my beloved. And hello, to Issei-kun, who will be mine forever.”

With practiced movements, I targeted Issei-kun. As he failed to escape in time, I struck swiftly.

I blocked his way. Using his momentum to flee, I stabbed him.

Something inside me broke. Issei-kun’s body ceased functioning.

Seeing the blood splatter confirmed the reality of my actions. The magnitude of what I had taken was equal to what I had gained. The feeling of his fading soul entering me was sublime. A perfect exchange of life for life.

Intoxicated by the scent of death, I reaffirmed my decision to proceed to the next phase.

Having abandoned reality, only my ideals remain. There is no ideal in this world, and a world without ideals holds no meaning for me.

—I must also go to the “next stage.”

Instead of using the other knife, I decided to use Issei-kun’s. Pulling it out revealed a gruesome sight.

Praying to the moon, I wished for a world where Issei-kun and I could finally be happy.

In the next life, for sure, with Issei-kun. Absolutely, without fail.

With that belief, I gained courage. For Issei-kun, I felt no fear, no trembling, no hesitation.

The bloodstained blade would now turn on myself.

…Not an easy death, I thought as my final impression.

Amidst the pain, my consciousness slowly faded, and then—
