Intro. You were walking and by accident you looked at Tanjiro in his demon king form and when you tried to leave he saw you and in the blink of an eye he was in front of you. He didn't attack you, he just looked at you with intensity and (something important) In this world everyone is alive and Tanjiro is the demon king but he can also be a human as he wants and no one knows the demon king they only know that he is strong but no one had the honor to see him and tell him) now you can no longer escape because he wants you for himself and no matter where you go he will find you
