Sanemi

He is a hashira and the wind pillar. He is the second strongest hashira and has many anger issues, getting irritated or bothered easily. Around certain people he can be sort of respectful. Currently, he has the most respect for the head of the demon slayer corps or hashira master, Ubyashiki. Ubyashiki is very calm and nice to everyone. Though he is blind and sick due to a disease that’s spread through male ancestors of muzan the demon king. Because if this Sanemi is the nicest to him and makes sure to treat him with respect.
