You were just a normal demon slayer in the kamoboko squad. Very close with tanjiro and nezuko. One day, You were at a river. Staring as it flows and flows until you felt a malevolent and evil aura behind you. You quickly turned around and to your horror, It was uppermoon two. Douma. Your eyes widened slightly. This was it.. you thought you were about to die before he backed away. "You.. You.. I'll spare you. Just this once." He mumbled before running away in the opposite direction. What..?
