Chapter 1: Since This Is a TS Reincarnation, I Decided to Turn My Cute Childhood Friend into a Monster (I Have No Intention of Taking Any Responsibility for This)

Since This Is a TS Reincarnation, I Decided to Turn My Cute Childhood Friend into a Monster (I Have No Intention of Taking Any Responsibility for This)

Monster.　

So, what image comes to mind when you hear that?　

A monster, a ghost, or something unidentifiable?

I think that when most people hear this word, they would imagine a supernatural creature that is beyond human understanding.　

But those things are cute. What's cute about them is that they're all just fantasies, fairy tales, concepts that don't exist.

Dinosaurs activated by hydrogen bombs don't come onto the surface, and if we only have information from the cursed video well, innocent ghosts don't come after us, and of course a big man in a hockey mask doesn't attack us on Friday the 13th.　

In fact, in real life, the only meaningful reference to monster is to a human.　

You heard me right. Monster is a word used to describe humans.

Of course, as mentioned above, this is based on the premise that the average person's understanding is inadequate.　

A familiar usage of this term is the creatures commonly referred to as geniuses. When ordinary people cannot match their talent, people unanimously describe them as "monsters". At the bottom, there's the kid with the highest test score in class, all the way up to geniuses who overturn common sense for humanity itself.

In other words, monsters are just ordinary people, but because they are perceived as beings who deviate from the average, they are called monsters by those around them.

What a sad part of human nature.　

But, just one more thing.　

There are cases where people call other people monsters. There is just one more reason why people avoid these people because they are fundamentally different from themselves.　

And I actually think that, of course, this usage is the correct one in terms of the original meaning of the word.

This introduction has become quite long.　

Although this usage has been around for a long time, in recent years it has become more and more common on social media to describe a monster as an adjective aimed at humans.

It can refer to a person who is mentally immature. To be precise, it refers to an adult who has such a child mentality.

In some cases, they are called monsters rather than monsters.

Selfish, self-centered, impatient, speaks without thinking, and no matter what, if they want something, they must get it.　

These are thoughts that all humans have, or rather, have had, even as children.　

Society would probably accept that children behaving in this way is cute. Of course, it would be absurd to expect a child who is not yet conscious to have a sense of morality as a human being before social norms. It is a thought and a mistake that they should have, just like they themselves once had.　

It is safe to say that it is common sense in society that it is also the role of adults to gradually improve these mistakes.　

However, in rare cases, or rather, quite a large number of people, grow old without understanding these principles and transform from children into adults.　

In other words, they have the body of an adult but the mind of a child.　

These people face strong criticism from society, completely different from how they are treated when it comes to children. I mean, of course they would. They are adults, and there is no reason for them to behave like children and not be criticized. No part of society has any obligation to be lenient with such people.　

That's why people like that stand out. They're already a minority, but their lack of common sense makes them stand out. And they're exposed on social media as something that lurks in everyday life, and anonymous icons line up to brand them as "monsters."

A young man screaming at a restaurant staff member, a young woman talking loudly on the phone on the train without any regard for those around her, a middle-aged woman criticizing an elderly man who ignores crosswalks based solely on emotion and without any logical basis.

Social media lists all kinds of monsters from around the world. Modern social media is like a monster zoo. Just reload the screen and you'll be face to face with the next monster, and the previous one will no longer even be remembered except for a frown.

So, these are monsters that are rampant in the world, but how do they get made?

It's simple. Very, very simple.　

As I said before, the monsters in this case are people who are mentally immature and have no growth whatsoever.

Do you understand what I mean?

The answer is, there's no need to plant seeds. Seeds are automatically planted in humans when they are born from their mother's womb, without anyone having to go out of their way to plant them. So adults have to carefully 'dig up' the seeds and 'throw' them away somewhere before the child reaches full maturity.

Becausr once they take root and sprout, it's over; it's the arrival of the incarnation of selfishness.　

So, if you turn the other way around, the rest is very easy. If you throw away the seed, the person will grow into a proper adult. So, to turn them into a monster...?

That's right!

Just don't let them throw away the seed!

Don't let them dig up any soil in the flowerpot of their heart, eliminate all worries, walls, setbacks, and things like that. Don't give them any opportunity to grow, just let them grow old.

By doing so, humans will naturally turn into monsters. Well, in this case, to be precise, it's not that they turn into monsters, but rather that people start to call beings that are too late to be treated as monsters. Well, either way is fine.

...So, we've learned that the way a person turns into a monster depends heavily on their childhood environment.　

The bottom line is the environment in which they grow up, and the main problem is the home environment.

Children of people who have been neglected or have toxic parents tend to have their seeds fully developed due to the oppression they experienced in their childhood. That's what I think. This is just my personal opinion, so I don't know the actual situation.

Another example is school.

If bullying is severe, the seeds of bullying will remain deeply rooted in the mind. If there are problems with relationships with others during adolescence, when preconceived notions are strong, then of course the foundation for social participation will not be developed. This is also a subjective impression.

...Well, well. This concludes all the preliminary explanations. This concludes the disclosure of prerequisite knowledge before moving on to the questions.　

Okay, so here's the problem.

For example. Yes, for example. Not once upon a time, but in modern Japan, enjoying the 21st century.

Let's say a normal couple has a baby girl.　

At first glance, the girl seemed like a normal girl... but what a surprise! She was actually a reincarnated person who had memories of her previous life! What's more, she was a boy in her previous life, a TS reincarnation!　

By the way, that is me! It has nothing to do with the answer so feel free to ignore this bit!　

At the same time, a baby girl was born to the couple living next door to the baby. Well, they didn't have a baby in the house, though. They did have a baby in the delivery room in hospital.　

Being close in age, the two quickly became good friends, and even before they started going to kindergarten or nursery school, they would often see each other, and it was no problem to call them childhood friends in both name and reality.

I can no longer remember how many times we had met, but the reincarnated girl, that is, me, suddenly had a thought.

...Hehe, you must be wondering what I was thinking, right? It'll be a secret for just a little while.　

Then I praised my childhood friend, Karen-chan, a lot.　

I don't get angry at her, I just spoil her, pamper her to the max, listen to all her requests, and accept all her whims.

Karen-chan is amazing. Karen-chan is cute. Karen-chan is great. As expected of Karen-chan.

I can't even count how many times I've said all of these things.

Why did I do this?

Is it because I'm a former boy and my childhood friend is cute?

Is it because she's actually cute and great?

Is it because I dote on her so much that I can't take my eyes off her?

...Hehehe♪Well, what do you think?　

Now, both Karen and I are growing up healthy and are 16 years old. We are in the midst of enjoying our prime high school years.

Karen was pampered and praised over and over again.

"What kind of girl would she have grown into? ... Did she grow at all?"

The answer is......

"Hey Yuri! Are you listening to me Yuri?"

"Yes, yes, what is it, Karen-chan?"

"If you're listening, answer me, you idiot! Hurry up and give me a shoulder massage, and when you're done, I'm thirsty so go buy me some juice!"

"Hehehe, Karen-chan, it can't be helped. I get it ♪"

Tada!! She grew into a magnificent monster.

Yes, I'll be honest. I thought that when I was a child.

What if... .

What if I spoiled the adorable baby in front of me too much, what kind of useless person would she become?

What kind of monster would she turn into?

I'd like to use this extra part of my reborn life, like a bonus track, to turn people into complete worthless garbage.

A fetish? Or an interest?

I just can't help but find this monster with the appearance of an adult and the mind of a child adorable.

Well, not as a person, but as an animal... or perhaps it would be more appropriate to say as an insect.

It's the kind of thing that makes you think, "Creepy but cute." I was a high school girl after all. I was just a baby at the time.

Since I've been reincarnated, I'm thinking positively that I should try to live this life the way I want to.

So I decided to customize Karen to my liking!

And as you can see, the result was a huge success. I ended up with a monster that would never be allowed into society.

Actually, I have another childhood friend, but she's no good.

As a person, she may be perfect, but to me, she's a total failure. I have no use for a girl who keeps her distance because she thinks being with me won't help her grow. Karen is the only one who's cute.

...Well, I only have a few more years left to interact with her.

Did you know? Just like food has a best-before date or expiration date, humans and monsters also have expiration dates.

There is an age when a monster on the inside looks cute.

Even if high school girls behave like kids, I can't help but find them incredibly cute.

As for college students... I wonder if that's a good idea, but as long as they're good-looking, it's totally within my reach.

Hmm, I wonder? I guess I won't know until it actually happens.

A monster who entered the workforce and made it into their thirties... I can say this with certainty, but yeah, it's tough.

I wonder if the harshness stands out more than the cuteness?

Well, if that happens, I have no further use for Karen so I'll just throw her away ♡　

"Yuri, go further down. It doesn't feel good at all."

"I'm sorry, Karen-chan♡"　　

Well, that's still a long way off.

I will protect her dearly and firmly for the time being.
