"Happiness as a father, and happiness as an demon slayer ... It might be normal to have only one... but I want both! Y/n Hoshino's a greedy boy, you know! I do not own Demon Slayer or Oshi no Ko, Demon Slayer belongs to Koyoharu Gotouge meanwhile Oshi no ko belongs to Aka Akasaka. A/n: This is my first fanfiction so hope everyone enjoy.
