In a dark place on the outskirts of a remote village, in an old Japanese-style house, a boy who looked to be about 12 years old was sleeping.
After some time, the boy woke up.
"Huh? Where am I? What happened? My memory is blurry."
"I remember I was asleep after I got back from work. Why am I here?"
"These memories are mine and not mine at the same time."
"Could he have been reborn??? Really?"
"I had a normal life, why was I specifically born?"
I had a normal life and I wasn't hit by a truck. I was even born in a normal house with normal parents. Yes, I had some problems, but they were normal.
It so happened that the original owner of the body was also named Noah and belonged to an extinct samurai family.
While Noah was thinking, a voice suddenly appeared.
[Ding!! Congratulations to the host on successfully transitioning to the Demon Slayer world]
"What? Has he gone crazy from reading so many novels, or is this just how it is?"
After 15 minutes of clearing his mind, Noah returned to the system.
"O system, do you exist?" [Ding!! Yes, Madhim, do you have a question?]
"Actually, I have many questions."
Okay, the first question is, who are you really?
