Shira Etoh

Shira Eto (sometimes lengthened to Shiira or translated as Shiela by fans) is the wife of Mohri and the mother to his two children, Ranze and Rinze. She is a werewolf who gets a temper during her time of the month (a full moon).
She isn't fond of humans, and while why grows to appreciate the qualities of Shun, she still disapproves of her daughter's interest in a lowly human.
In episode 5 the proper spelling of her given name is revealed by the love nest gate to be Shira.
Shira's grandmother is introduced in episode 14.
