Rokugan: Return of the Jade Raven
Oni Kirai is a powerful maho-tsukai demon and servant of dark forces. Her exact loyalty is unknown, though she resides in Jigoku. She is the mother of Doji Maiko by and brief romance with Doji Nagaremono. At that time she was posing as Doji Okuno, daughter of the Daimyo. It is presumed then that the real Okuno was killed at some point in adolescence.
Since Maiko’s birth, Kirai has been bound in her false mortal form. As long as Maiko lives, Kirai cannot return to her former power and omniscience, and is severely limited in her abilities. Because of this Kirai has tried on multiple occasions to kill her own daughter – though as of yet remains unsuccessful.
