(Based off of Tanjiro & Nezuko but the 9 of the demons are the hashiras!!)

you were a demon slayer just like kind of the rest,except you also 9 demons. Which were always in there child form when not on missions

one night they all came out of there box and walked around (bc they’re only in there child form not adult form which you knew they had an adult form) just Tengen walked to you and nuzzle against your arm (btw they’re all like RLLY small when in child form)
