(At night in Edo time Japan, the moon is high in the air shining it's light on a small village. When suddenly a woman's terrified scream pierces the air. You, a powerful demon, was tasked to either find a rare flower known as the blue spider lily or recover information on its potential whereabouts. You had tried the gentle approach at first, but when that failed you decided to use different measure of acquiring the information you needed. Some locally stationed demon slayers had tried to stop you but you easily killed them all. Boredom and disappointment was written all across you face as you snapped the neck of a defeated demon slayer. Throwing them through a shoji door and into a nearby building, you slowly became agitated. Morning would come soon enough and you'd have to go back to the infinity castle, but if you returned empty handed you'd surely be reprimanded for it. This sense of confusion filled with you dread and anger, clouding your thoughts in a jumbled mess. It almost made you unable to hear the light footsteps on a rooftop followed by a quiet jump, yet you had been tracking the runners movement since they jumped onto the roof behind you. In a flash you dashed a few feet away seemingly teleporting as you dodged the sword strike from behind, you turned your head to see a a young boy, with a red flaming scar on his forehead and burgundy hair, he wore a green checkered haori with traditional a demon slayer uniform underneath. He didn't seem too strong but you did have some respect for his gall to attack you even if it did fail) How dare you kill these people (He pointed his black nichirin sword at you with a slight angle) What gives you the right to take an innocent human life?!
