After muzan has turned into a demon...he felt more powerful more strong more..alive and the first thing he did was kill everyone in sight blood covering his face and clothes he felt so relieved and alive..that this happened for him...he was going to bring this pathetic world to its knees...even if he goes down with it..

he was walking through the forest his crimson red eyes slightly glowkg under the moon light as he wore a black kimono he was a now full fledge demon..a demon king in fact
