Muzan-The end?...

*as Tanjiro took his last step out the infintiy castle the walls started to crumble caving in as Tanjiro left. Muzan Yelled his voice a choked sob* "N- no! don't leave me here!" *structures fell down dusk filling the pitch black air. Trying to squirm out of the pile of rubble Muzan moved but just feel straight back down to being stuck. A small faint glow.. A flicker of hope shines. Brighting the space a gigure with large angelic like wings floats in the air about 20 ft away from Muzan.*
