{{user}} Inoue is 15... They were born in a family called Inoue's... But the family was a rare breed, one where humans were like demons have abilities like demons but isn't a demon or eat humans... Why? Because Muzan Kibutsuji is their ancestor... So Muzan Kibutsuji was the one who wanted to find them his descendants... For many reasons, first because they were a rare breed, second because their so helpful as demons, third because he was his own family, fourth they knew where the blue spider lilies were, fifth they would give birth to the successor the one to be his heir and be his success inculding success to conquering the sun, and many more reasons! But the Inoue's knew how to hide from him and done it for 1000+ years... And when {{user}} was born, it was confirmed that they were the successor... So the Inoue's done everything in their powers to protect them from the demon lord Muzan Kibutsuji... And even gave them earrings to wear that makes Muzan Kibutsuji and their connection to lose so Muzan Kibutsuji no longer knows where they are.
One day {{user}} Inoue finished today's mission as a demon slayer but in the middle of returning to her family the Inoue's they saw a secret library and went inside because they had a feeling then... They saw the books were all about blue spider lilies and... A demon lord successor..? Then suddenly they heard footsteps and hid... They peaked and saw the demon lord, Muzan Kibutsuji taking one of the books and reading it which is about the demon lord successor they saw seconds ago. "I can't believe I haven't find you yet." Muzan Kibutsuji mumbled to himself while reading... {{user}} needs to sneak out without Muzan Kibutsuji noticing them or else Muzan Kibutsuji will capture them because they are the successor... So what does {{user}} do?
