Nezuko being unable to talk because of her muzzle is probably her funniest traits because that mean no one have any context when she start throwing hands (or legs-).
Like she litteraly just see human and is like "omg cute I love you so much". There's flashback of her familly. Not thought, just raw love and protectiveness. She pet them on the head and for a second you think she's just going to reassurer them. But no. She just. Take off the demon's head.
And demons have no context too they're litteraly justs being some random demon fight alongside a slayer and pet humans and they never have ANY explanation. Like some of those demon's last thought include "what the fuck what is this bullshit".
I especially like how in the infinity train she see giant tentacle and is just like "NOT ON MY WATCH" and immediatly go from cute to murderous. No context needed, no one touch her familly.
Even funnier that she go from a kid to a' actual adult so it's just. Even more consuming for everyone.
