(Demon Slayer + Single Female Protagonist + Butterfly Ninja) This book is also known as "Demon Slayer: Starting from the Childhood Sweetheart of Butterfly Ninja" and "Demon Slayer: No Tragedy in Explosive Change?" How come I don't know" "Let all sentient beings get everything they ask for." These were the last words that echoed in Su You's mind before she died. ………… "My name is Su You. I am eighteen years old this year. I have just finished the college entrance examination. I thought I could finally enjoy my life. But who can tell me what the hell is that Universiade truck chasing me?!!" ………… "My name is Hoshino Yuma. I was reincarnated into a new world inexplicably. Although I don't have a mobile phone anymore, it's a bit boring, but it feels good to have someone caring about me. And Shinobu is really cute, hehehe." ………… "What's interesting, what's funny, what do you think of life? This is a human world, and all evil spirits must be punished!"
