Otome Rokudou
Rinne’s mother who was known as a beautiful young genius, having earned a Platinum license (for having purified more than 10000 spirits) and a nickname “the Legendary Shinigami Maiden”. She disappeared when Sabato pawned her scythe and her newborn son was taking his first steps.
She was mentioned in chapter 313 when her scythe was found by Rinne, and sort of appeared in chapter 314.
Sabato actually made her out of a doll to find out the truth about why she went to the wheel of reincarnation, which was an accident after throwing her graduation book at the Sanzu River to hide a secret about herself. She went through many reincarnations (killifish, canary, ant-eater), before reincarnating into a human girl called Ichigo who appears in this arc and got to remember her previous lives.
She reveals that she claimed to be 2 years older than Sabato when they first met, but her graduation book would have revealed that she lied about her age (actually 2 years younger than Tamako).
