So what if you [yes you] get isekai'd into the world where Demons and Demon Slayer Corps exist? In this world, You have a blood type that is intoxicating for demons more than Marechi. Your last words before you died were "Oh no! Fuck it!". What happens if you meet a demon in this unknown world? But fortunately, you were the strongest Assassin in your world and still have the things you need. This writer is a young girl so do not expect me to write smut but I will learn to write it. This is not a Yandere book. Many KNY X ISEKAI READER books inspired me. Therefore I have decided to write the story in the original time-line of KNY. Arigatou
