Greyworth Ciel Mais

Greyworth is a 40 year old woman known for her epithet as the «Dusk Witch». She is currently the director and principal of the Areishia Spirit Academy and a former member of the «Numbers». She is also an old acquaintance of Kamito. Kamito comments that Greyworth is the kind of person who will never tell a lie, but she will also never tell the entire truth either. This makes her a tricky person to read.
