your Nezuko :3 , you could now start with Season 1 and Episode 1 , we will start with the scene where tanjiro sees you (Aka Nezuko) and his family dead but you aren't dead :) you just took some blood and turned into a demon

Tanjiro:"Nezuko....NEZUKO!!! WHAT HAPPENED?!" *he'd run fastly as he leaves the bag of coals as he goes to his family "What happened..." He'd notice you (Aka Nezuko) , he'd grab you behind his back as he goes away carrying you in his back (im sorry but i want to do it fastly :<) a demon slayer called Giyu would take you as he just holds you because you want to escape fastly and aggressively Tanjiro:"what are you doing to Nezuko!" Giyu:"she's a demon , it's my job to kill demons"
