School had only just begun…
But my mind was somewhere else.
Another world.
The system had already found two possible destinations:
Demon Slayer: Kimetsu no Yaiba
Jujutsu Kaisen
I just needed the right time to travel.
As I walked through the hallway, someone caught my attention.
A quiet boy with long hair tied loosely behind his head.
Piercings hidden by his hair.
Wait…
Isn't that Izumi Miyamura?
So that means the world ofHorimiyaexists here too.
He was a year above me.
If the timeline was correct, he should already be close withKyouko Hori.
I shrugged slightly.
"Not my problem."
I walked into my classroom.
Like always…
I sat in the last seat by the window.
The perfect seat for a loner.
Technically I had classmates.
But no real friends.
Just acquaintances.
As I settled into my seat, someone approached me.
A familiar voice.
"Um… Hikki…"
I looked up.
It was Yui Yuigahama.
Right.
The dog this morning.
She bowed slightly.
"Thank you for saving my dog earlier!"
I sighed.
"It wasn't a big deal."
I brushed it off quickly.
Talking too much would just attract attention.
Class soon started.
And as expected…
It was unbelievably boring.
Math.
History.
Literature.
I'll be honest—
I was never a great student.
But I endured it.
Finally…
The school day ended.
I returned home quietly.
When I entered my room, I noticed something on my desk.
An envelope.
Inside was an invitation.
A publishing event for my novel.
Location:
Yokohama
That worked perfectly.
A multi-day event in another city was the perfect excuse.
I walked downstairs.
"Mom, I got invited to a publishing event in Yokohama."
She looked surprised.
"Really?"
"What about school?"
"I'll manage," I said calmly.
After thinking for a moment…
She nodded.
"Alright. Just be careful."
Then someone jumped into the conversation.
"Onii-chan! Take me with you!"
Of course.
It was my little sister.
Komachi Hikigaya.
I shook my head.
"No."
"I'll only be gone for four or five days."
She pouted dramatically.
"Mean!"
My mother looked slightly suspicious.
Normally I avoided events like this.
But this time I was going willingly.
Still…
She didn't stop me.
The next day, I traveled to Yokohama.
Once I checked into a small hotel, I locked the door.
Then I spoke quietly.
"System."
A blue screen appeared.
"Let's go to the Demon Slayer world."
Ding. Preparing world transfer.
Ding. Host please be ready.
A strange energy surrounded my body.
The room around me began to fade.
Ding. Host has entered the world ofDemon Slayer: Kimetsu no Yaiba.
Darkness swallowed everything.
And a new adventure began.
