Sakai Chigusa

Chigusa is Yuji's mother. Her husband, Kantaro, works outside the country. Chigusa remains ignorant of Shana and Yuji's true nature, but becomes a source of good advice for Shana on matters where Alastor can not counsel her. The Crimson Lord himself acknowledges and bows to her wisdom after a phone call between the two of them. Described as a woman who can accept anything, she seems to harbor absolutely no problems with Shana often visiting Yuji under the pretext of "training".
