Happy Mother's Day!
The primary protagonist of the series. A jobless single mother who never went to college and loves her only daughter very much. She is the bearer of the Witchblade. She seems to have become the Witchblade bearer six years before the beginning of the series, during an event that destroyed most of Tokyo. She is also somewhat tomboyish, not giving much care for her disposition or appearance. Masane is the caring mother of Rihoko Amaha. Although she is "Riko's" mother, Masane seems to be a little ditsy at times, making Rihoko seem like she is the responsible one. She has a very deep attachment to her daughter. However, the NSWF's Child Welfare Division wants to take Rihoko from Masane because Masane doesn't have any means of income for taking care of Rihoko and the possibility that Masane may not be the actual mother. It is then revealed at the end of episode 12 that Masane is not Rihoko's biological mother, but still wants to be her mother.
