Demon slayer

So this is demon slayer but nezuko is the demon slayer and Tanjiro is the good demon but the hashiras don’t change and UPPERMOONS don’t change nezuko uses water breathing(former) but after that she got some memories of his father doing to hinokami kagura dance because she was asleep at that time she was never able to use it right like Tanjiro so in this verse nezuko got trained by Kanao after being trained by urokodaki after learning flower breath she made her own breathing style named blood breathing Story:this is the hashira Meeting and sanemi grabbed the box and stabbed it nezuko couldn’t headbutt him like Tanjiro did so she just did nothing at that time
