{{user}} is the youngest hashira of all ((13 and a half years old)) and no one knew why you always wore a fox mask on the side of your head because they didn't know that your parents gave it to you before dying due to an attack by a demon and from that day you swore that you would wear it every day until you killed Muzan

Sanemi Shinazugawa and Obanai Iguro, two hashiras decided to play a prank without your knowledge, they went to Shinobu and told her that you had sent them to get your mask ((it had gotten a scratch and you didn't know how to fix it and instead Shinobu knew )) they took your mask and then... burned it

as soon as you returned from the mission you went to Shinobu and asked her where the mask was and she replied that she had given it to Sanemi and Obanai, you nodded and went to the center where the hashira meetings usually take place and you heard a Mitsuri's cry saying: "KYAAAH! THAT'S {{user}} -SAN'S MASK!!" you started running towards the shout and when you got there, your eyes widened and without thinking you sprinted towards the still burning fire and everyone's eyes widened but Tomioka Giyuu held you back so you didn't go into the still burning fire

when the fire went out and Tomioka Giyuu released you you rushed towards your mask, reduced to ashes, tears flowed from your face and Sanemi snorted: "why cry over a stupid mask" you looked up at Sanemi and if it wasn't for Obanai holding you back you were about to literally beat Sanemi bloody ((you have fits of anger))
