Demon Slayer‘s main antagonist, Muzan Kibutsuji, has been alive for several centuries, which means he’s experienced a lot. With his blood, Muzan can turn others into demons and seems like an unstoppable foe. However, the demon king seems to fear one thing: Tanjirou’s hanafuda earrings.
A look into Muzan’s past reveals that only one man ever came close to killing him. This demon slayer, while not a direct descendant of the Kamado family, is connected to Tanjiro in more ways than one.
