I am Kotaro Kenshin. Despite having the 'Kenshin' in my name, unfortunately I am not a swordsman. I am is just a normal person living a normal life in this old times.
Being a teacher, having a sufficient and slow life is all I want and I have it all. All I need is to have a beautiful wife. And today is the day for one of the many matchmaking date.
And then I met the girl with long black hair tied in braids, having a very beautiful face.
"Nice to meet you. I am Kotaro Kenshin."
"N-Nice to meet you as well, Kotaro-sama. I am Mitsuri Kanroji."
What?! Mitsuri Kanroji?! The Love Hashira?!
I am in Demon Slayer World!
