The Hashira's

The original Hashira's:
Gyomei
Sanemi
Muichirou
Iguro
Rengoku
Tomioka
Mitsuri
Uzui
Shinobu

They all sadly failed to defeat kibutsuji but didn't fail to kill the uppermoon's. muzan still turning people to demon new uppermoon's and lowermoons. until the new Hashira's step in and take the battle for their own and get revenge on those who sacrificed their lives. you may know who they are.
