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.

Sabato actually made her out of a Yorishiro 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.
