This is a story of how Saiki, a introverted boy that craves to be alone and normal forever. However one day when he was five, he met a girl that is the same age as him, let's just say that he had fell heads over heels for her. "Oh (Y/N), my precious angel, I will protect you forever~". Warning:Blood, Swearing and Gore, if you feel uncomfortable by it then feel free to leave the book. Read at your own risk. (Also I don't own the anime The Disasterous Life Of Saiki K and the characters in the story. I just decided to make a yandere story about it. However, I only own the story's line and I make it for my brain but if you don't want to read it then don't read it but anyways enjoy if your going to continue reading it).
