Rasetsunyo

Rasetsunyo (羅刹女) is the mother of demon prince, Kougaiji.

Background
Unlike the other women that the Ox King Gyumaoh kept, Rasetsunyo was married to the powerful demon. She was sealed in a pillar in Houtou Castle’s hall by Gyokumen Koushu. Her living(?) form has yet to appear in the series, but she did possess the maternal feelings that Kougaiji wholeheartedly adores, and that in the distant past, she was intimate with Gyokumen Koushu.
