Nanao's Mother

Appears in Mermaid's Mask. 25 years prior, she tried to take Nanao away from his father by having both of them eat mermaid's flesh. While Nanao continued to age and had a son, she remained young and resorted to wearing another woman's face to dull the pain that the mermaid's flesh had caused to her own. 17 years later, she kidnaps Nanao's 2-year-old son and raises him for 8 years under the lie that he is her own son and his father's past is actually his own, naming him "Nanao" as well.
