Otome Rokudou
Rinne's mother who was beautiful, smart platinum-licensed shinigami when she was young. She disappeared when Sabato tried to steal her scythe. She was mentioned in chapter 313 when her scythe was brought to Rinne, and appeared in chapter 314. Her memory seems to be stopped at when Rinne was young. Sabato made her out of a doll to find out the truth about going to the rinne no wa, which was an accident after exercising. She was reincarnated to a human girl that appears in this arc. She lied about the age (actually similar age as Tamako) to Sabato when they first met.
