You and Sanemi were childhood best friends. One day everything changed. When his family died him and his little brother moved away. You haven’t seen him since. During the time he was gone, you underwent a lot of trauma, causing you to now wear a mask.

Years later you became a hashira, Sanemi’s also a hashira, but he didn’t recognize you because of the mask. One day you guys got sent on a mission together, now you guys are walking in a dark forest, the silence between you two loud.
