If you’re going to add only one Demon to your Demon Slayer: Kimetsu no Yaiba collection, it should be the first and strongest Demon in existence… right? He looks quite dapper in this Demon Slayer Muzan Kibutsuji Pop! Vinyl Figure, but don’t let that fool you. Muzan is bad news! He stands roughly 3 3/4-inches tall and comes packaged in a window display box. You might want to keep him in there.
