I Am Cain Who Destroys Demons

Ye Yang, who traveled through Demon Slayer, became the ancestor of vampires? No misfortune? Want to be a ghost king? Are you dreaming? Nezuko? Don't you want to become a ghost? Don't want to eat people? Then become my first embrace and live by sucking blood! Butterfly Ninja: "Huh? You're not a ghost? Huh? There are many people too? What are you?" Tanjiro: "Brother, I will leave Nezuko under your care. I will definitely avenge my mother and the others!" My wife, Zenitsu, said, "Oh no, this big brother looks so scary. I'm afraid I'll die just by looking at him!" Tomioka Giyu: "I told you! I! I am not hated!" Alas, being a vampire is so troublesome, so I have to drag myself out to bask in the sun and drink wisteria tea to survive! This novel and its characters are purely fictitious.
