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

My name is Evianne Vivienne, and I feel like something is strange lately with the people close to me.

Although they look and act as always, for some reason I feel a strange sense of incongruity, as if they were actually someone else despite being and behaving like themselves.

But despite that, I try to appear calm while desperately trying to convince myself that I'm just overthinking things, or that's what I kept repeating, hoping it really was the case.

.... But as if my fears were real, I slowly discovered that I wasn't wrong.

The first person I noticed this sense of incongruity in was my mom, whom I always saw as my role model for being a consistently calm person who never ran, screamed, or got angry while treating everyone with kindness.

But when I came home one day, that same mom came running to greet me, being the first time I saw her do that, but at that moment I didn't have time to be surprised by that when I saw what she was wearing when she greeted me...

She was wearing a childish girl's costume that I hadn't worn in years since I used it for some past Halloween, and it was too tight on her, making her belly and large breasts stand out, while underneath she wore a very short floral skirt.

She even had her hair usually pulled back in a bun, now tied in pigtails... Even though Mom was 37 years old at the time, she seemed to be trying hard to look like a small elementary school girl.

But back then, what was even more shocking than her appearance were the words she said to me at that moment: "Uhoh ♡! Welcome home, my cute Evi!!"

At that moment, instead of her usual gentle "welcome home," she spoke to me with an overly sweet and inappropriate voice along with a nickname she had never called me, leaving me in shock and leading me to unconsciously ask her about her outfit, only to receive an even worse reply like: "Oh this? The truth is I wanted to wear other prettier dresses of Evi's, but these big cow breasts and huge butt ripped them, and I could barely put this one on... So even an old witch like me can look cute!"

She continued saying vulgar words I never thought I'd hear like "butt" or "old witch," so feeling scared, I took a little distance from Mom for the first time until then, and over time she started acting like herself again, as if what happened at that moment had just been a nightmare.

But as I grew older, I increasingly noticed Mom's abnormal behaviors, like the lustful glances she gave me and my friends, or the way that the older I got, the less she dedicated herself to or paid attention to me, almost as if I no longer existed to her...

Everything seemed to continue this way with an uncomfortable atmosphere at home until, while wondering what to do one day, Mom returned from shopping with a flushed face, babbling things about love at first sight and so on, while mentioning some kind of cute silver-haired "magical girl" she saw for an instant on the street.

Since then, she has become obsessed with finding this "girl," desperately searching for any clue while irresponsibly investing money in her own hobbies, like when she bought an inappropriate girl's costume that she gave to some kind of "idol," according to her.

Perhaps I would have just considered this the awakening of some strange hobby on Mom's part if that had been all, but unfortunately, other people close to me began to show sudden changes just like Mom...

An example would be my best friends Pia and Malia, who overnight started dating a man with no redeeming qualities and giving him money as if it were the most important thing to them, to the point that when I said something negative about him, they started behaving mechanically like dolls and tried to attack me.

Fortunately, nearby people stopped them; however, while being restrained, they started insulting me with expressions of hatred I had never seen before...

That day I lost two of my most valuable friendships without knowing what I did wrong, and all I could do was cry....

But while I was in a depressive state, I met an antisocial and isolated boy from class, obsessed with all kinds of supernatural phenomena, who extended his hand to me while telling me about strange and incomprehensible things that had happened to him.

This is how I began to suspect that perhaps there was a reason for the abrupt change in the people I cared about, while he invited me to join a club made up of people who had also gone through similar situations... Determined to discover the truth, at that moment I decided... And I took his hand, becoming part of the "paranormal investigation club."
