Demon Slayer 1x21-22 | Watch Along

just to clarify, the hashira are not in charge so on the note of assuming everyone would know about Tanjiro traveling with a demon and lack of communication, birds, etc., there wouldn't be any communication about this to them in the first place. Its just the master who is in charge and who would have this info. The only way they could have known is if he told the hashira.
