A character from the backstory of the manga and anime Spy X Family. She was the biological mother of the main character Anya (Spy X Family). Judging by her wearing the same hospital gown as her daughter and expressing a desire to soar through the skies like a butterfly, she was likely imprisoned by the same scientists who experimented on Anya, inadvertently granting her the superpower of Mind Reading.
From her limited appearances, she resembles an older Anya or Ashe (Rengoku No Ashe) from Rengoku No Ashe, another manga by Endou Tatsuya.
