社畜のオッサンがモブ悪役（奴隷商人）に転生したら、ゲーム知識を利用して、ヒロインたちを最強に育成するわ、無自覚にヤンデレ化させるわで、いつのまにかストーリーをへし折りまくっていた件。

At 35 years old, and with no girlfriend in my entire life, I suddenly felt a sharp pain in my chest one night. Before I knew it, I had been reincarnated.

The place I was reborn into was the world of “Lunatic Wars,” an RPG that gained a cult following 25 years ago.

However, I wasn’t reincarnated as the protagonist.

In fact, I ended up as the mob villain, the s*ave Trader, who kidnaps the heroine early in the game and gets defeated.

If things stay like this, eventually, the protagonist and heroine will come to rescue her and kill me in an event.

So, I decided to treat the heroine as kindly as possible, and while I was at it, I used my knowledge of the game to help train her.

But…because I have zero social skills, my relationship with the heroine didn’t improve at all, and time just kept passing by.

On top of that, since I’m a mob character, my level didn’t increase at all.

Realizing that I was just waiting to die, I decided to release the heroine in hopes she’d let me go.

“Master…what do you mean by abandoning me…?”

For some reason, the heroine’s mu*derous intent was terrifying…

And on top of that, it seems I went too far with her training, because her stats had somehow surpassed those of the final boss…

At this rate, I’m going to be killed by the heroine before the event even happens.
