A handyman at the Pan-Human History Security Organization, Finis Chaldea.
That's my current position.
To put it simply, I'm just an ordinary person, a background character 'A'.
It's the all-too-common trope of being reincarnated into a game I used to play.
I have no idea why something like this actually happened, though.
Still, since I was reincarnated, I tried my best to fulfill my role as a handyman. But something here is... strange.
It's so different from the game I played, from the story I knew, that it's just bizarre.
For starters, there was this big, muscular, bald man whose face was hard to see, leaving only a hazy impression. A man with bronze skin, incredibly muscular arms, but a prominent potbelly.
He looked like a character straight out of one of those doujins.
That first impression turned out to be the worst possible.
I became self-aware after the Incineration of Human History had already begun, and at some point, Chaldea had been completely taken over by that guy.
From what I remember before I became aware, he was the type to fool around with the female staff, and it seems he was secretly doing it with Da Vinci, too.
Starting with Da Vinci, who had been 'conquered' long ago, even the Director, who had somehow survived, and all the female Servants summoned by the protagonist were stolen away by that man.
I had some knowledge of the original story, so I tried to secretly give the protagonist advice, but it seemed useless.
The protagonist, Ritsuka Fujimaru, had the same personality as his character in the original story. But this world wasn't the original story I knew.
This was a world based on an erotic doujinshi.
There's no other explanation. Otherwise, there's no way that Mash would be in another man's arms, moaning and looking at Ritsuka with contempt. She would never have been corrupted to that extent.
On top of that, in this world, Romani and Fou never existed from the start. Romani was simply never here, and I've never once seen Fou. I'm not a particularly good or pure person, so I could understand him not being near me, but I never saw him around Ritsuka or Mash either.
Eventually, the thing I had feared the most happened.
They forcibly gender-bent Ritsuka, who was a man, and began his 'corruption'.
Of course, it was mostly limited to him being assaulted, and true to his nature as the original protagonist, his spirit never broke.
Was it like Vegeta, whose pride remains unbroken even when his body and mind are controlled?
As an extra just watching from the sidelines, it was all the more heartbreaking.
It's a ridiculous story. It was so hopeless that it seemed like it would have been better for him to just break and find some twisted form of happiness.
They were all happy amongst themselves, while only Ritsuka suffered.
I tried to comfort and care for him, but that was all I could do. Just offer words of consolation or bring him food.
There was nothing I could do. Like a true extra, I had no aptitude as a Master, nor could I Rayshift. I couldn't even attempt to summon a male Servant.
Well, even if I had summoned a male Servant, I doubt he would have been normal. I gave up on that idea after seeing the female Servants, powerful as they were, lose to that man's brute force.
I never thought I'd live to see the day Shuten-Douji's horns were broken.
In the end, I just lived my life quietly. Sometimes that guy would act friendly and suggest I should have some fun with the women, but I always refused.
Sure, they're all beautiful. Far too beautiful for a commoner like me. But I have no interest in women who would betray their master to screw around every day.
They all just played and ate, throwing the Restoration of Human History to the dogs, and it seemed Chaldea was fine with that.
I don't know how much time passed like that. Then one day, while living in this convenient, crappy world…
I regressed.
I had returned to the time before the control room bombing, with all my memories intact.
For a moment, I wondered if it was all a dream, if I had returned to the original world. But no, this was a regression.
I held onto a sliver of hope, right up until I snuck into the workshop and saw that bastard groping Da Vinci's ass.
And so, since I've returned, I've decided to do something.
That's why I decided to tell Ritsuka everything and give him my advice. As a mere extra and not a Master, this was the best I could do.
"That's everything I experienced. It might sound like the ravings of a madman, but I'm serious. I'm genuinely worried about you, Ritsuka."
"No, I believe you. I can feel your sincerity."
"I'm glad you believe me."
Just having someone listen is a good start. The only problem is…
Why is she a girl from the start? What changed, and where? The Ritsuka I knew was a black-haired boy, but before me stood a beautiful girl.
Right, she already looked like the Gudako from when she was forcibly gender-bent by that guy.
I have no idea why.
For now, let's just do what I can.
After all, I really hate NTR. And since I've come back in time, I might as well go all out.
