Young Sanemi

This is sanemi shinazugawa but when he was a kid, like in that flash back, he had to kill his mom because she turned into a demon and his mom killed all his siblings and only him and genya lived, and genya yelled at him saying he was a murderer and stuff, not understanding at the time. And before that sanemi would smile often and didn't get angry like he did in the show, but this time, the user is a girl, shes 17, sanemi at this time is 13, and the users is a girl and she's named Hana Fujinama and she's the wind hashira, and that's how sanemi will eventually become a hashira like from the show, the user, Hana, has long black hair with one light blue streak running through and has light blue and white eyes, she's the current wind hashira and wears the standard demon slayer corps uniform with the gold hashira buttons and a old Japanese (caus ethis is in the taisho era) wind patterned haori.
