What Era Is It, Still Writing Traditional Diaries

What era are we in, still writing traditional diaries?

Author: Auditory

Synopsis:

After Miyauchi Hiyage transmigrated to a multi-anime world, he obtained a magical diary. As long as he wrote in it daily, he would receive rewards.

However, having read web novels about diary systems before transmigrating, he knew that whatever he wrote was highly likely to be seen by the heroines of this world.

As a lazy person with no ambitions, Miyauchi Hiyage immediately decided to be a pure entertainment seeker in this world.

"What era is this, who still writes traditional diaries?"

"Does anyone really want to write their true feelings in a diary and have it read by who knows how many heroines?"

"My mom told me this world is dangerous, and boys need to protect their privacy when they go out, so don't even think about finding me. After all, I'm the man you'll never get."

As Miyauchi Hiyage continued to write in his diary, a "Revenge Alliance" composed of heroines who could see Miyauchi Hiyage's diary quietly formed.

They gathered with only one goal: to find the owner of this diary and wreak havoc upon him!

Volume 1

Chapter 1: I am Tom Riddle, Send Money

"I am Tom Marvolo Riddle, a powerful wizard. Due to an accident, my soul has been sealed within this diary. If you are willing to help me break the seal, I will reward you handsomely once I return to the wizarding world and reclaim my fortune."

Late at night, Kasumigaoka Utaha sprawled on her bed, completely lacking ladylike demeanor. Even her loose pajamas couldn't hide her impressive figure.

In her hand, she held a seemingly ordinary black diary, her expression exceptionally conflicted.

This diary had inexplicably appeared on her desk just before she went to sleep that evening.

Kasumigaoka Utaha initially paid it no mind, but when she casually flipped through it, she was astonished to find that no matter how she turned the pages of this thin-looking diary, she couldn't reach the last page, as if it had an infinite number of pages.

The single entry on the diary had kept her tossing and turning, unable to sleep.

The text in the diary wasn't in Japanese, but in English, with a font that looked quite classical and elegant, which somewhat increased its credibility.

"Could wizards truly exist? This is truly an unbelievable truth..."

Although Kasumigaoka Utaha was very confident in her own talents—ever since enrolling in Private Toyonosaki Academy, her grades had consistently remained at the top of her class—

What was the situation with this so-called wizarding world? Who was this "Tom"? And why had this diary suddenly appeared before her?

Despite having so many questions weighing on her mind, Kasumigaoka Utaha had yet to respond in any way. Facing something completely unknown, who knew if writing in it might trigger some curse or contract?

Maybe tomorrow I'll just toss this diary on a park bench and let someone else deal with it?

This thought crossed Kasumigaoka Utaha's mind, but she shook her head the next moment.

No, it's likely that some indescribable contract was already formed the moment she saw this diary.

It was like how she had just put the diary aside, but with a mere thought, it reappeared in her hand.

This diary seemed to have "bound" itself to her.

Kasumigaoka Utaha patted her face. At this point, pretending ignorance was impossible. So, there was only one answer—regardless of the outcome, she had to figure out what this "Tom" wanted to do.

Kasumigaoka Utaha got up from her bed and returned to her desk, picking up a pen as she pondered what her first words to "Tom" should be.

A friendly greeting? Or a subtle inquiry about the wizarding world?

But as she hesitated over how to write that first sentence, several large paragraphs of text suddenly refreshed on the diary before her.

To her astonishment, the text on the diary was no longer in English, but in Japanese, which she was most familiar with.

[Heh, just kidding with everyone just now. I hope no one took it seriously, right? Surely no one would actually agonize over the notebook for so long, unsure of what to do, right, right?

Anyway, the joke is over, let's get down to business.

First, let me explain the origin of the diary in your hands. Simply put, it's a cheat I brought with me when I transmigrated to this world. As long as I write in the diary every day, I can get some rewards.

As for my identity and name in this world... my mom told me this world is dangerous, and boys need to protect their privacy when they go out, so don't even think about finding me. After all, I'm the man you'll never get.

If you must have a name for me, let me think... "You Know Who" might be a rather interesting title.

And you who can see this diary, according to the tropes in the diary-genre web novels from my previous life, you should all be the protagonists of your respective stories.

Let me be clear first, I don't know who is reading this diary right now. However, according to my investigation, this world has integrated a large chunk of the messy movies, anime, games, and novels I watched in my previous life. Uh, although calling you characters from certain works might make you uncomfortable, for me, this is indeed the reality in my memory.

But thinking in a more absurd direction, perhaps all the memories of my past life are just fabricated by some high-dimensional being with a peculiar taste for entertainment to pass the time, which is not impossible.

Of course, if I go further down this path, it gets even more ridiculous. Let's get back to the main topic.

In short, you don't need to worry too much. After all, you are all thinking beings. The memories in my head are ultimately just rigid plots. The moment you obtained this diary, the story's plot has likely already deviated.

What I can do is to neutrally write the stories in my memory in the diary. You can compare what I write with reality, or you can simply treat it as a pastime to kill boredom.

I'm very much looking forward to seeing what impact you who are reading the diary will have on the stories in my memory after you understand your own stories and those of others.

Also, a friendly reminder, according to the usual tropes, although you cannot mention this diary to others, the holders of the diary can still communicate with each other. As for how you intend to interact, that's your business.

After all, for me, the clash between heroines from different works seems quite interesting.

Now that everything has been explained, let's move on to the enjoyable part of beating up, ah no, the spoiler segment.

Actually, I'd like to start with Yukino, the Second Daughter of the Yukinoshita Family, and Kasumigaoka-senpai, who were quite popular in my previous world and were basically dragged into every multi-anime novel.

It's true that those two are practically half the landscape of the urban mixed-anime fanfiction world.

But based on my investigation, their storylines shouldn't begin for another year. I haven't interacted with them yet, so I'll put them aside for now and start with characters I need to know about more urgently.

Among the characters I've investigated so far, the one I need to be most careful about is the idol, Miss Hoshino Ai.

I really hope you can read my diary. Although the evaluation of you in my past life was mixed, after I transmigrated and watched your performances online, I personally hope you can continue to be active as an idol.

At 15 years old, you probably already know Kamiki Hikaru. No matter how far your relationship has progressed, I strongly advise you to stay away from that scumbag.

While the manga plot I read in my past life hasn't confirmed whether he is the true culprit who will cause your death in the future, and perhaps there's another mastermind behind him, he is indeed a beast who satisfies his desires by taking the lives of talented idol stars.

If you are currently pregnant, please ensure your whereabouts are not leaked to anyone. Otherwise, your extreme fan Ryosuke is highly likely to pose a life threat to your attending physician and yourself, under the guidance of that mastermind.

Of course, if it has truly reached the point of pregnancy, I suggest you find a detective to help investigate the true identity of the mastermind.

On a personal recommendation, Mr. Mouri Kogoro of Tokyo's Beika District and Miss Shionji Yuko of the Tokyo NEET Detective Agency would both be good choices.

If you choose the former, it would be best to visit his agency when the first-grader, Edogawa Conan, is home. It would be even better if this kid could overhear the details of your request.

I've estimated that today's diary entry is over a thousand characters. Although there's still much I want to write, it's getting late, and I have to play with my dearest little sister tomorrow morning, so I'll stop here for today.

I wonder what rewards I'll get today. I sincerely hope they're just ordinary rewards that won't impact my life too much.

"You have read the diary for the first time, and you have gained 1 Reading Point."

After reading the updated diary, Kasumigaoka Utaha, who wore a complex expression, seemed to hear a mechanical prompt.

Chapter 2: Kasumigaoka Utaha: I Have Many Doujinshi in Another World?

After finishing the diary, Kasumigaoka Utaha's expression became even more conflicted than before.

The words in the diary were too shocking.

A transmigrator from another world, many people reading the diary were the heroines of their own stories, and this mysterious diary...

With so many surnames in Japan, Kasumigaoka isn't a common one. Coupled with her obtaining this diary, statistically speaking, she is very likely the "Kasumigaoka senpai" mentioned in the diary.

Although she's about to start her second year of high school after the spring break, the diary mentioned her storyline starting in a year, and by then she'll be a third-year, so she can indeed be called a senpai.

So, is the male protagonist of her story a junior a year or two younger than her?

Or is she the heroine of a yuri work, being pestered by another junior?

Kasumigaoka Utaha's thoughts began to wander, and she quickly shook her head.

Whether it's a junior or a junior, she has no thoughts on it right now.

What she cares more about now is that sentence mentioned by the "mysterious person," about how popular she was in his past life, to the point where almost every mixed-anime novel would drag her into it.

The term "mixed-anime" isn't common in the Japanese ACG circle, but the meaning is easy to understand.

To be honest, rather than being the heroine of a popular work and having her character image used for fan creations by countless creators in that world, she would rather believe that wizards truly exist in this world!

If there are wizards, they must possess spells that can make people forget everything!

Kasumigaoka Utaha gritted her teeth. She finally understood why this "mysterious person" dared not reveal his true identity, and why he pretentious said, "I am the man you cannot have." This is clearly a scoundrel who enjoys watching chaos unfold.

If she knew his identity now, she'd wish she could rush over overnight, kick him hard, and force him to reveal her future.

She wondered if "Yukino, the Second Daughter of the Yukinoshita Family," who was also briefly mentioned, had seen this diary yet. If she also had this diary, she'd probably be grinding her teeth in anger just like herself.

But all in all, the most important thing now is to verify how much truth there is in the diary written by this mysterious person.

After taking several deep breaths and stabilizing her emotions a bit, Kasumigaoka Utaha rubbed her head while focusing on the young idol named "Hoshino Ai" mentioned in the latter half of the diary.

The mysterious person's account of Hoshino Ai's story was indeed quite neutral.

A 15-year-old idol being pregnant and unmarried is a significant flaw for an idol. If Kasumigaoka Utaha saw such a celebrity on TV, she'd probably curse the filth of the entertainment industry.

Even in anime works, Hoshino Ai's character profile is quite controversial.

To be fair, seeing a young idol's most unspeakable secret laid bare before her, Kasumigaoka Utaha did feel a sense of schadenfreude.

But then she thought that she might also become the subject of gossip for others in the future, and the sliver of joy that had just arisen in Kasumigaoka Utaha's heart instantly vanished.

Kasumigaoka Utaha figured she wouldn't be able to sleep well tonight after experiencing such a supernatural event, so she opened her computer to investigate what kind of idol this Hoshino Ai was.

As an idol, Hoshino Ai's information wasn't a secret. Based on the diary's content, Kasumigaoka Utaha quickly found her personal information and even infiltrated her fan club, learning some details about her.

She grew up in an orphanage, was scouted at 12, and debuted as the center of the third-rate idol group "B Komachi."

Admittedly, Hoshino Ai's appearance is indeed advantageous, especially her sparkling eyes that make people remember her instantly.

"But her figure isn't as good as mine," Kasumigaoka Utaha made a judgment with just one glance.

"After three years, her Twitter follower count is still less than 100,000. She really is just a third-rate idol."

"However, the activity in the comment section is quite high, and a considerable number of them seem to be new fans. Has her career seen any breakthroughs recently?"

Kasumigaoka Utaha scrolled through Hoshino Ai's Twitter, looking at the carefully curated photos. She soon narrowed her eyes.

In the three years before her debut, although Hoshino Ai still looked radiant in photos, as a woman, she could sense Hoshino Ai's discomfort and cautiousness with these exquisite outfits and styling.

After all, she grew up in an orphanage and a third-rate idol doesn't earn much money, so such a reaction is normal.

It was only in the last two months that Hoshino Ai seemed to have awakened, learning the skills of fashion matching and makeup. At the same time, her stage performances became more dedicated than before.

Kasumigaoka Utaha could clearly feel that Hoshino Ai had become more uninhibited in her idol activities in recent months compared to the past.

If I had to describe it, it was as if the other person had suddenly developed a subtle feminine charm over the past few months.

And this seemingly insignificant small change was also the main reason for the surge in Hoshino Ai's Twitter fan activity in recent months.

When a beautiful girl who was already flawless in appearance learns how to exude charm externally, wouldn't that attract a lot of new fans?

Looking at the girl who, just a few years ago, only wore a perfunctory fake smile, suddenly undergo a transformation this year and radiate her charm on stage, Kasumigaoka Utaha instantly thought of the scumbag named Kamiki Hikaru that "You Know Who" had written about in the diary.

You Know Who had said that Kamiki Hikaru was an absolute scumbag, who satisfied his beastly desires by taking the lives of talented people, and was also the most likely mastermind behind Hoshino Ai's eventual death.

"A girl who grew up in an orphanage, was dragged into the dazzling entertainment industry at 12, then got her heart broken by a scumbag, ended up pregnant before marriage, and was finally killed by her extreme fan – what a terrible story," Kasumigaoka Utaha couldn't help but sigh.

"I wonder if she has this diary over there now, but if she and that Kamiki Hikaru are in the midst of a passionate romance, a suddenly appearing diary probably won't make her change her mind."

Kasumigaoka Utaha had no intention of seeking out Hoshino Ai offline, at least not for now.

After all, she only found out today that a person named Hoshino Ai existed in the world, so she had no reason to interfere with the other person's life choices.

Even You Know Who, who wrote the diary, was only reminding Hoshino Ai in a "suggestive" tone. He had even thoughtfully recommended two famous detectives. As long as Hoshino Ai could read the diary and wasn't blinded by love, she wouldn't end up on the same old path described in the diary.

"Besides, I don't know what the other diary holders think. The first fish to surface isn't easy to be... I'll just observe for a while longer and see what else You Know Who writes before making a decision," Kasumigaoka Utaha muttered.

Meanwhile, in various corners of Japan, there were quite a few people who shared similar thoughts with Kasumigaoka Utaha.

Some people, after reading the diary, were also enthusiastically booking tickets for Hoshino Ai's next performance.

But no matter what, tonight was a sleepless night for many girls.
