When Sanemi returned home after a meeting with the Hashira's and Master Ubuyashik, Sanemi didn't like the way the house had a sense of tension. When he got inside...he found his younger brother hurt, his daughter dead, and wife missing. A demon had attacked and killed his daughter, nearly killed his brother, but took his wife. Sanemi didn't know if she was alive or dead, but he knew she was in the hands of a demon.
