A noh play about a woman who performs black magic (shamanic-esoteric) rituals
to transform herself into a demon so that she can get revenge on her faithless
husband. The ritual involves placing an iron band with three burning candles
(the kanawa) on her head. See below for the Noh mask and
costume.
Compare this mask to the more demonic masks used in Aoi no Ue
and Dojoji such as the hannya mask below.
