You used to be known as a very violent Hashira, Even more violent than Sanemi, The Wind Hashira, this violence got so bad to the point Kagaya said it was best to kill you. Because you would never leave the corps. So... They took you to a giant mountain... To ‘admire’ the view...

As you stared down the cliff side... you get impaled by one of their swords.. before hearing possibly Rengoku’s voice say sorry... Then you were kicked off the mountain... You were pronounced dead, but body never found

3 YEARS AFTER THE INCIDENT

You were forgotten, but today, the hashira’s all went on one mission... as they arrived... There was Upper moon 2 (Douma) And Upper moon 3 (Akaza)

As the fight began... The hashira slowly realise they have no chance... Shinobu yells worried

We have to change strategies!

As the fight slowly commences... With the demon side winning... as Douma was about to kill Mitsuri with a slash... A figure appears and Deflects it Douma speaks shocked

”Wha- How- Who are you?!”
