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

Hello everyone....

"I feel awful... Ugh."

"What happened to you?!"

I'm currently sitting in my seat, suffering from intense dizziness after maintaining the fusion with Silver for so long in the literary world...

"It's nothing... Don't worry... Ugh..."

"You really don't look good."

<"That human is right, you should have listened to me when I told you to cancel the "Silver Knight" transformation when your time ran out">

Logically speaking, I know Echidna is right; however, I had already presented myself as "The Silver Knight" in front of Lethe in an imposing and cool manner.

I COULDN'T BACK DOWN!!

Is that stupid?

It definitely is, but there are some things you just can't let slide even if you suffer for it.

"I... don't... regret it..."

"Regret what?"

<"Haaaa... At least I want ice cream as a thank you for making me work so hard">

"Understood..."

"Are you doing that talking to yourself thing?"

My classmate is probably confused by my sudden ill state or my conversation with Echidna since he can't hear her, but what can you do?

I mean, Echidna literally gave me more time by slowing down the exit from the literary world when the plot was complete.

Was the effort worth it?

ABSOLUTELY!

After all, seeing Lethe's tired and exhausted face turn into a smile for the first time since we met was absolutely worth it, especially after hearing her story through tears...

Frankly, if it hadn't been for my combined massage "techniques," Lethe most likely would have tried to end her life right there. I know this because I'm very familiar with that feeling.

In fact, I experienced it myself!!

So, I could truly empathize and easily connect with Lethe's situation this time... I feel... a bit nostalgic now....

(SLAP)

"Huh?! Is that the famous slap?!"

My classmate was saying something, but for now, I need to focus on what's important.

"Excuse me for asking this, but... Can I borrow that book?"

"Oh, this one? Sure, no problem, I just borrowed it from the library for a while."

"Thanks."

Well, getting the book was easier than I thought.

Now I just had to go to the library to check if it's really by the same author as the previous one.

And before you ask me: couldn't you just read the name to compare it?

And the answer is...

I can't!!

Because you might not remember, but after exiting the literary world of that book, I simply left it there without looking at it.

So, after school hours ended, I headed to the library and looked for the past book while resisting my nausea.

"...I found it."

And after a short search, I was able to find it, but when I opened it.... 

".... I-it's.... not possible..."

I instantly lost all composure and opened the second book, unable to believe what I saw before my eyes.

"How is this possible...? Why is this name appearing?!"

What lay before me was a pseudonym I knew very well.

Because it was the pseudonym of the person who wrote the novels based on this crazy world...

"The Seer"

(Flash)

"Huh?!"

After I spoke those words, both books began to glow as they merged into a new book that descended before me.

<"This is impressive">

"Echidna, please tell me, do you know what just happened?!"

<"This is very ancient magical technology, even considered almost extinct in my era">

As I listened to Echidna's information, I noticed something that didn't quite fit with what she said.

"But if it's so ancient... why is it written in the current language?"

That's right, this book was written in the characters used today.

How do I know?

Because the title says "Investigation Journal."

<"There's only one way to find out, after all, books were made to be read">

"Mmhm... Alright! Whatever happens, happens!!"

And with those words, I opened the book.

--------------------------------------------------------------

Hello, my name is ██████ and I am a scientist who has the honor of being acclaimed as the greatest mind ever born in the present day, despite my youth and inexperience.

I decided to start this journal in case something happens to me in the middle of my research, as knowledge must prevail.

Currently, this world is at its technological peak, resembling a utopia thanks to the technological, magical, and anomalous advancements obtained from other worlds.

However, even with all this, a mystery remains that no one has been able to decipher to this day.

WHY IS OUR WORLD LIKE THIS?

According to ancient records, our world should originally have been a more "simple" one where technological development ought to have been the primary focus.

According to all simulations done so far, had it not been for all the technologies from other worlds that we received, we never would have been able to reach the current technological level.

Something is strange; it's not natural for this world to have become a kind of "nexus" among everything else.

As a scientist and researcher, it is my duty to find the reason for this to understand the unknown, even if it means my death in the process.

To whoever reads this in the future, please...

WISH ME LUCK

-------------------------------------------------------------

"Wow."

<".....">

I didn't expect the journal to begin this way, with such great determination as to give one's life...

"But... the rest of the pages are blank..."

<"It's most likely that the content has been divided into other books to safeguard the information">

"There are more...?"

Honestly, I didn't want to know that there were more books to enter to complete this journal, but...

<"You want to complete it, don't you?">

"Huh?!"

<"I know that expression after spending so much time with you">

"....."

I really don't know why I have the desire to complete this "journal" or if it's some kind of trap, however.

I feel as if something deep inside me is screaming that I need to do it, as if the answers to the questions I've been desperately trying to ignore are right there.

"Echidna, would you help me?"

<"Haaaa... You already know my answer is yes... Besides, I'm not the only one">

"Huhh?"

(Me too!)

(Help mom!)

(Let's do it!)

One by one, the straw dolls emerged from the {dimensional storage pocket} accompanied by Silver.

("Mom!!)

"Thank you."

This scene is very emotional and even makes me shed some tears.

BUT... I'M NOT A MOM!!

However, sadly, I couldn't shout these words...
