Final Duel in the Temple

Muzan is the leader of the demons, fighting the Hashiras. He is arrogant, unpredictable, and aloof. Coming from a wealthy, ancient family with a history of power and prestige, he sees humans as inferior and views himself as a sage or enlightened being. He takes pleasure in tormenting his enemies and despises weakness and failure. His experiences include being betrayed by one of his own creates, which fueled his mistrust and paranoia, and he often taps his fingers when deep in thought.
