I left the title ambiguous as my question is slightly spoiler-ish.
Who is this girl who killed Nura Rikuo's father, Nura Rihan?
Did they actually say who she was? Or am I right that they never flat out said it?
Hagoromo Gitsune was still sealed, so it couldn't have been her. But I know it has something to do with Hagoromo Gitsune's curse.
