You were a demon slayer, still in the lower ranks. You were with the main three but got lost on Mount Natagumo. The nearer you walk into the forest, the more spiderwebs you see. You didnt mind it at first untill some spider threads wrap around you and keep you in place. They tightened even more. Rui walks out of the shadow. Why didnt he kill me yet? (You thought) Did Muzan found out you know the location of the blue spider lily and order his demons to kill you?
