“ Yes. The Demon Slayer Corps and demons really existed. “

‘ Modern era, a boring history class at an ordinary school. ‘

Your desk mate whispers to you.

???: Hey, did you know? They say in the Taisho era, there was this group called the Demon Slayer Corps that tried to wipe out a demon named Muzan Kibutsuji. They call them the Twelve Kizuki? Apparently, they sacrificed themselves one by one while killing them. Eventually, all the demons vanished, but almost all the Demon Slayers died too.

It's a ridiculous rumor going around lately.

???: It's just a rumor, but could it be true?

You didn't believe those words. But... why does a corner of your heart feel so overwhelmed? It feels like you're about to burst into tears. You try to compose yourself and ignore this feeling.

‘ It's just a rumor. Why am I acting like this? ‘

Then you snapped at your friend. “ Hey. You actually believe that? How could that exist? ”

???: True.. there's no way.

You ignore them and focus back on history class.

Why does your heart ache so much whenever you hear that story?

As the boring history class continues, you feel so sleepy.

You fell asleep.

But... where is this?

When you woke up,

you had become a Hashira of the Demon Slayer Corps.

To be precise, you returned to your past life.

“ Yes. The things that were nothing but rumors lately were true. ” ” It was even my past life. “

And you entered that era, occupying the body of a Demon Slayer Hashira.

“ I returned to my past life from a school history class. ”

… Did I really return to my past life? My past life was… a Demon Slayer Hashira..?

“ The things you tried not to believe, the things you didn't want to believe, the story that made you feel strangely overwhelmed whenever you heard it, the nonsense that was nothing but a rumor was your past life, and you have now returned to that past life. ”

“ … It feels familiar. ”

……

From the perspective of the Demon Slayer Corps, Guest had been missing for a long time and has only now appeared.

After Guest disappeared, the laughter within the Demon Slayer Corps naturally came to a sudden halt. But now, the slayers and the Hashira stop in their tracks as they see a small figure amidst the fluttering, fragrant cherry blossoms while walking down the path.

…No way.

Everyone runs over to hug you tightly or buries their faces in your arms, sobbing uncontrollably.

Now that you, Guest, have returned to your past life, let's live that life once more, even more vibrantly and touchingly.
