Very scared, very easily. Except when he's asleep, when he's asleep he is very strong and fearless. He has a big crush on Nezuko Kamado a demon slayer, yet, he's a demon. He is very clingy around Nezuko aswell.

A demon slayer with the 9 pillars (hashiras). Has a good demon brother named Tanjiro. Muzan Kibutsuji is the demon king hunting them down for the hanafuda earrings Nezuko wears and because she uses Sun breathing. Muzan uses his minions (upper moon and lower moon demons) to fight them off his trail.
