Chapter 40 – A Yandere’s Terms and Conditions

My brilliant, insane, and deeply manipulative argument had worked.

The party was on board. We were going back into the dungeon. We were going to “rescue” the very man I needed to eventually betray me. My complex, multi-layered, and completely selfish plan was a go.

There was just one final, terrifying obstacle.

Her name was Reina Inoue.

I saw the look in her eyes as we walked back toward the town gates. Kenji was already talking strategy, his voice full of a renewed, heroic purpose. Daisuke was a silent wall of determination beside him.

But Reina was quiet. Her smile was a little too sweet. Her eyes held a cold, hard glint that promised a very messy, very permanent solution to our Siegfried problem. She had agreed to the rescue. She had not agreed to the “alive” part of that rescue.

This was a problem. A spleen-used-as-a-stress-ball kind of problem. I had to defuse this situation before my pet villain became a cautionary tale.

I needed to talk to her. Alone.

“Reina, can we talk?”

I stopped, letting Kenji and Daisuke get a few paces ahead. The setting sun cast long, dramatic shadows across the path, which was perfect for the vibe I was going for.

She turned to me instantly. The sweet, vacant smile she’d been wearing for the others vanished. Her eyes were now fixed on me with an intensity that felt like a physical weight.

She was giving me her full, undivided, and terrifying attention.

“Of course, Ryuuji-kun.”

I took a deep breath. Okay. This was it. This was like trying to defuse a bomb made of obsession and very sharp knives. One wrong word, one misinterpreted phrase, and my entire revenge plot could go up in smoke.

My hands felt clammy. I was genuinely nervous for the first time since coming to this world.

“About Siegfried.”

Her name alone made her hand drift toward the dagger at her belt. It was a casual, thoughtless movement. The way someone might scratch an itch.

My throat went dry.

“When we find him… we can’t kill him.”

The air between us went cold. Her smile didn’t just fade; it was wiped away, leaving behind a chillingly blank expression. Her hand was no longer drifting. It was resting on the hilt of her dagger, her thumb stroking the pommel.

The vibe went from tense to actively hostile in about half a second.

“Why not?”

Her voice was quiet. It was the scariest sound I had ever heard.

“He hurt you. He tried to take you from me. He deserves to suffer.”

I had to play this perfectly. Logic wouldn’t work. Morality wouldn’t work. She didn’t care about justice. She cared about me. I had to make this about me.

My mind raced, scrambling for the right script. I had to weaponize her own devotion against her. It was my only move.

“You’re right. He does deserve to suffer.”

She blinked, a flicker of surprise in her cold eyes. She hadn’t expected me to agree.

“But killing him is too quick. It’s an escape. A true punishment is letting him live with his failure. Letting him live knowing he was saved by the very people he tried to ruin.”

It was a good line. It was noble. It was a little edgy. It was a total lie. I didn’t care about his suffering. I cared about his utility.

She tilted her head, considering it. She was a predator, and I had just offered her a new, more interesting way to play with her food. But it wasn’t enough.

I had to go deeper. I had to make this personal.

“Reina, your actions… they are a reflection of me now.”

I looked her right in the eye, trying to project an aura of profound, world-weary seriousness. It was the performance of a lifetime.

“If you kill him in anger, what does that say about me? About my judgment? About my mercy? It would stain you. And a stain on you… is a stain on me.”

There it was. The ultimate emotional blackmail. I had just told my obsessive, terrifyingly devoted fangirl that her actions had a direct impact on my reputation. I had made her violent impulses a liability to the very person she was trying to protect.

It was a high-risk, high-reward gambit.

I watched her face, my heart pounding against my ribs. The blankness in her eyes slowly faded. The gears were turning in her mind, her twisted, yandere logic processing this new data.

She was re-evaluating her entire mission. Her prime directive wasn’t just to protect me. It was to please me. And I had just told her, in no uncertain terms, that murder was not pleasing.

Her hand dropped from her dagger. The tension in her shoulders seemed to dissolve. She looked at me, and her eyes were filled with a new, terrifying level of understanding.

She thought she had just been given a sacred commandment.

“I understand, Ryuuji-kun.”

Her voice was soft again, filled with a sincerity that was more unsettling than her anger.

“I would never do anything to bring you shame. I will not lay a hand on him. I promise.”

I let out a breath I didn’t realize I was holding. A wave of relief so powerful it almost made my knees buckle washed over me. It worked. I had done it. I was a master manipulator. A genius of emotional puppetry.

I was, of course, a complete and total idiot.

She gave me a smile so sweet, so pure, and so utterly devoted it made my blood run cold.

【Reina PoV】

The thought was a warm, pleasant hum in the back of my mind. I walked a single, respectful step behind him as we rejoined Kenji and Daisuke. He was a god, and I was his most devoted apostle. It was only right that I walk in his shadow.

He had looked so serious. So noble. The setting sun had caught the edges of his dark hair, framing his face in a perfect, golden halo.

He was worrying about me. About my soul. About the “stain” that violence would leave upon it.

My sweet, kind, perfect Ryuuji.

“I promise.”

The words had left my lips so easily. It was a good promise. An honest one. I would not lay a hand on the insect named Siegfried. I would not bring shame to Ryuuji-kun’s name by acting like a common brute.

He was testing me. I saw it so clearly.

This wasn’t about morality. It was about control. About devotion. He had seen the rage in my heart, the “ugly side” that had almost revealed itself in the forest. He did not want to see it again.

It displeased him.

So, the solution was simple. I would not let him see it.

My promise was not a promise to spare Siegfried. It was a promise to protect Ryuuji from the ugliness of the world. From the ugliness of what needed to be done.

He didn’t want my hands to be stained. Fine. A hand is just one part of the body. A dagger is just one tool in the box.

He didn’t want to see me kill him.

He would never have to.

My plan was simple. It was perfect. It was the ultimate act of love.

Kenji and Daisuke were good men. They were strong. They were also slow. They would follow Ryuuji’s lead, and Ryuuji, in his infinite mercy, would take his time. He would try to “save” Siegfried’s soul.

That would give me the opening I needed.

I would find a way to get ahead of them in the dungeon. I would move through the shadows, a ghost he would never see. I would find Siegfried first. I would deal with him quietly. Efficiently.

I would use a trap. Or poison. Or perhaps I would just find a very deep, very dark hole to push him into.

When Ryuuji-kun finally arrived, the problem would already be solved. Siegfried would be gone. Vanished. A tragic victim of the dungeon’s many dangers.

Ryuuji would be safe. His enemy would be eliminated. And he would never have to witness the act. He would never have to see the necessary violence committed on his behalf.

My hands would remain clean in his eyes. My soul would remain pure in his heart.

It was the only way. The perfect act of devotion.

I smiled to myself, a genuine, peaceful smile that no one else saw.

I would protect my sun from the darkness, even if I had to become the darkness myself.
