Chapter 1 — Mōri Ran's Surprise: Turns Out I'm Living in an Anime World
The anime world—
A land filled with mysteries, knowledge, and wonders.
Beika City, Mōri Detective Agency.
Mōri Ran was cleaning her room as she usually did.
When she lifted her bedsheet to toss it into the washing machine, something unexpectedly slipped out and hit the floor with a soft thud—a sound that resembled a book dropping.
Curiosity tugged at her, and Ran bent down to pick it up.
The moment her eyes landed on the cover, she froze in shock.
Written in large, clear letters was:
[Hayashi Rin's Diary (Mōri Ran's Exclusive Copy)]
"Hm?"
Hayashi Rin? Who is that?
She had never heard that name before.
And why in the world would his diary end up in her room?
More importantly, why was there a note on the cover saying 'Mōri Ran's Exclusive Copy'?
What did that even mean?
Her curiosity only grew deeper.
Could this be another weird thing Conan dragged home again? she wondered.
Ever since that little boy named Conan moved into their home, strange things had been happening one after another.
Her father, Mōri Kogorō, was constantly being dragged into criminal cases every other day.
Even stranger, every time they went to a crime scene, her father would mysteriously faint… and then wake up later as if blessed by divine enlightenment, solving complex cases with impossible accuracy.
People had even started calling him "Sleeping Kogorō."
On top of that, Conan had a bad habit of running around crime scenes, picking up all sorts of unusual things, and occasionally bringing them home.
Ran sighed as she stepped out of her room with the diary in hand. The moment she saw Conan in the living room, she called out:
"Conan, is this your diary?"
Conan blinked in confusion before answering, "Eh? Ran-oneechan, a diary? What diary?"
"This one," Ran said, lifting the object in her hand.
"I don't write any diary," Conan replied innocently.
Ran frowned. She looked at the diary again—it was right there, clear as day.
But Conan couldn't see it?
At that moment, Mōri Kogorō lowered the newspaper he had been reading and looked at his daughter with a puzzled expression.
"Ran, are you so tired lately that you're starting to hallucinate?"
"What diary? I don't see anything in your hand."
It was rare to see Kogorō this serious, but right now he was stroking his chin with a thoughtful look.
"How about this—let's go on a short trip this weekend. You need to relax before you get too stressed."
He paused, then shot her a teasing glance.
"Or don't tell me you've been thinking about that brat Kudō Shinichi again?"
"Hmph! That kid is so irresponsible. He's been gone for so long and hasn't even called you once."
Finished with his comment, Kogorō lifted his newspaper again, though his eyes flicked sharply toward Conan from behind the pages.
Conan could only groan inwardly.
He's right… I haven't contacted Ran in a while. Maybe I really should call her from a public phone soon…
Ran stared at the diary.
It finally dawned on her that this object truly could only be seen by her—and that only made her more confused and strangely fascinated.
"Oh… maybe I really am hallucinating…" she murmured uncertainly.
But her curiosity won over her doubt.
She returned to her room, shut the door tightly, and slowly opened the diary.
What she didn't know was that at this very moment, all across this world—both near and far—countless extraordinarily beautiful girls were doing the exact same thing.
Each one opening an identical diary, each one filled with the same curiosity.
Ran turned to the first page, and the very first sentence made her freeze.
[I have time-traveled. I really have time-traveled.]
[Even though I've read so many novels about protagonists jumping between worlds, I never imagined it would happen to me.]
[I've always believed in science. I grew up a rational atheist. The idea of 'reincarnation' was nothing but fiction to me. I never thought it could be real.]
Ran's eyes widened as she read those words.
"Time-travel? Isn't that the theme of those novels that are popular lately?"
In this world, reincarnation and isekai-themed novels were indeed trending.
For example, the famous novel That Time I Got Reincarnated as a Slime was wildly popular among students.
Ran herself had read a few similar novels, so she understood the concept well enough.
But reading those words directly from a mysterious diary that only she could see…
She found herself whispering while biting her lower lip:
"Time-travel? That's impossible… this has to be fake. There's no way someone could actually cross worlds."
Yet when she remembered how Conan and her father hadn't been able to see the diary at all while she could, her certainty wavered.
Am I really just too exhausted…?
Or is this diary something supernatural? And everything written inside it… is actually true?
If that were the case…
Then someone named Hayashi Rin had really, truly crossed into another world.
With a mix of curiosity and unease, Ran continued reading.
[I can't believe it—I've really traveled to another world. I've become one of those rare lucky people who get to experience this.]
[And even more shocking—I ended up in a two-dimensional anime world.]
[Sure, anime worlds are filled with beautiful girls. I like them too.]
[I admit it… I like Mōri Ran, Takanashi Rikka, Suzumiya Haruhi, Misaka Mikoto, Hinata Hyūga—there are so many anime girls I like from various worlds.]
[But come on! I never wanted to actually transmigrate for real! If I disappear like this, what about my parents? They would have to bury their own child!]
[Still, since I've already time-traveled, what else can I do? Luckily, I have an older brother and a younger sister who can take care of our parents.]
[Dad, Mom… I'm sorry. I can no longer be by your side in this life. I hope we can meet again in the next one.]
Ran flushed deeply.
This Hayashi Rin…
He wrote that he liked her!
Even though she felt embarrassed, an odd flutter stirred in her chest.
I don't even know him… yet he wrote something like that about me?
But the next line confused her even more.
"A two-dimensional anime world"?
Was he implying that this world—the world she lived in—was actually an anime world?
Like something that only existed in manga and animated shows?
"This… this makes no sense…" she whispered.
Her mind felt like it was spinning, but her curiosity compelled her to keep reading.
[As someone who has transmigrated, I should technically be blessed with protagonist-level good fortune. Maybe one day I'll awaken a special ability—a golden finger—that will help me rise to the top, become immortal, even break through dimensional boundaries.]
[If that happens, maybe I'll be able to cross worlds and return to Earth—appearing before my parents with the power of an absolute ruler.]
[Now that I think about it, that doesn't sound too bad.]
[Besides, this world is a fusion of countless anime worlds. Anything could happen here.]
