Reincarnated in a depressing erotic world but living a normal life (right?)

How did it all begin?

Even today, I ask myself that question, and I always remember that day when I lost everything I cared about and knew in an instant...

That day was like any other, illuminated by the warm morning sun, as a pleasant feeling of tranquility invaded me while I slept by the window breeze in the classroom.

"It's time to start the meeting of second-year Class B to represent the performance at the school festival."

At that moment, I could barely hear the teacher's voice due to the drowsiness of sleep.

"Rima, don't fall asleep, have you already forgotten the scolding from the last time you were caught?"

"Mmm... Okay... I get it..."

"It doesn't seem like it."

The one who woke me up at that moment with a sharp voice was my classmate and best friend, Ilana, who was sitting next to me.

She was very important to me, and we had always been together since elementary school. We were almost inseparable, believing that wouldn't change no matter how much time passed... It really... was a beautiful dream... But that dream came to an abrupt end and turned into a nightmare...

"Last time, I had asked everyone to think of ideas for a show, so I'll start by writing them down..."

At that moment, I still remember how hard it was to stay conscious due to sleepiness and how if I let my guard down, I would lose consciousness. Honestly, I just wanted to go home to play video games or sleep a bit more, thinking it would be another calm and boring day, without knowing what was about to happen...

I truly wasn't aware of how happy or fortunate I was when I was living such an "ordinary" scene, doing things like going to class, eating slowly, or chatting with Ilana, and only realized how lucky I was when I had already lost everything...

"Hey! What's that?!"

Accompanied by the loud shout of a boy in the classroom, who stretched out his arm to point out the window, that's when everything began.

"What's wrong? Why did you shout like that all of a sudden?"

"L-look out there, that... Something is floating in the sky! And it's getting bigger and bigger!!"

His voice trembled with fear as he screamed with all his might, causing the class representative to give him a doubtful look, tilting his head.

But he wasn't the only one, as the people around were doing exactly the same. Even I thought, "What's going on now?", with a somewhat irritated attitude, because after all, that boy was known for being a troublemaker in class.

It's not that he was a bad person; he was just... too playful and always said weird things like that to surprise those around him, to the point where it went from being fun to simply annoying or boring.

.... Although on that occasion, he really seemed to be telling the truth when the representative reacted to where he was pointing.

"Uh.... What's that?"

When the representative said that while heading towards the window, it unexpectedly ended up piquing the curiosity of many students who approached to observe. Fortunately or unfortunately, due to my own laziness, I ended up staying there lying down, looking in the opposite direction and avoiding falling victim to whatever "that" was.

"This isn't real, is it?"

I could hear Ilana's voice next to me as she also looked outside, just like everyone else, including the teacher, while showing expressions of surprise.

At that moment, my heart was racing as curiosity or a strong, uncontrollable impulse drove me like an obsession to look at what "that" was.

"Aaaaaaaaaaaaaaaahhhhhhhhhh!!!!!!!!!!!!!!!!!!!!"

But at that moment, before I turned to look, a shrill, sharp, penetrating scream resonated that tore my eardrums, waking me from that kind of trance.

Trying to find out who had let out such a scream, I found the most popular girl in class, who was smiling with a demonic intensity, showing her teeth and raising both hands above her head.

"Hahahahahahaha! Yes! I'm a bunny!... Hop♡, hop♡, hop♡, hop♡, hop♡!"

She suddenly crouched down to start hopping like a rabbit while repeatedly saying she was a bunny, not stopping even when she bumped into desks or anything else, continuing to hop as if nothing else mattered.

That was the moment when all my drowsiness disappeared, replaced by fear and the accelerated beats of my heart, as a thought invaded me:

If she's like this, what about the others?

And it was when I asked myself that question that I finally came out of my state of confusion to begin noticing the commotion around me that my subconscious had silenced.

.... But even when I remember it, the only word that could correctly describe it was "chaos".

"Dick. Sex. Cum inside. Feels good. Dick. Sex. Cum inside. Feels good.!"

On the other hand, another normally quiet and shy girl was now mechanically repeating nonsensical vulgar words while exposing her large breasts, which boys used to tease her about, as she drooled, standing motionless at her seat.

This frenzy of madness was unleashed throughout the class, with everyone seemingly losing their minds as some began to masturbate, others to have wild sex, and others waved their arms or bodies frantically, repeating senseless behaviors....

Seeing such a scene for the first time, I thought perhaps I was the one who had gone crazy without knowing what was happening. However, the reality was that the only sane one in that room... Was just me.

"Hey Rima, did you see it?"

Turning when I heard Ilana's voice next to me, I was paralyzed by shock when I saw her.

"It's beautiful! Wonderful! Oh, it's, it's, it's, God! You must look at it, look at it, look at it, look at it."

Her eyes were empty, and saliva flowed from her mouth like a waterfall as she simply stared blankly at "that" outside.

"Rima, what are you waiting for? You have to see it!"

At that moment, she tried to grab my head to force me to see "that" which had done this to everyone else, so I instinctively dodged her and distanced myself.

"Why do you resist? All humans should see it."

At that moment, I was only afraid and unable to think rationally, which is why...

"Ah! Where are you going?!"

.... Without knowing what to do, I ran while keeping my gaze on the ground, trying to avoid looking at "that"; all I could do was... Run.

After that, I hid until nightfall, trying to calm down for a long time, until...

(!!!ILLUMINATION!!!)

A thunderous sound and a flash of light illuminated the night sky were visible throughout the city, leading me to look up only to find a beautiful starry sky that gave me a moment of respite as I lost consciousness, falling into sleep, hoping that everything would return to normal upon waking...

However, what welcomed me upon waking was the vivid image of a completely mad city where no one seemed normal, and everyone had gone insane.

My parents, relatives, friends, all of them had gone mad, and the city that once felt familiar had transformed into something completely different, being covered by a strange fog that prevented me from escaping or contacting the outside.

2 years have passed since then, and now, in a city full of demented perverts, and I being the only "sane" one, I have become the "crazy one" from the perspective of others, living my life almost in isolation, thinking that nothing was going to change.

"Hey, Sara, where are we?"

"Sara is an idiot so she doesn't know."

".... I really should have hit Kim when I had the chance."

Or so it was supposed to be, until for the first time in years... I saw someone "sane" arrive.
