Yasaka is a nine-tailed fox and the mother of Kunou. She is an extremely powerful Youkai that is on par with an Ultimate-Class Devil, and is the leader of the Youkai in Kyoto.


Yasaka has both a human form and a fox form. In her human form, she appears as a young woman with a voluptuous figure and very long blonde hair with matching eyes. She is a woman with delicate facial features and her eyebrows are cut very short and round a symbol of nobility. Her hair is usually tied in a loose ponytail, reaching all the way down to her legs that ends in a spiral, with taut bandages to keep it in place. She usually wears a traditional shrine maiden attire, and over that she wore a white coat held closed by a red ribbon and a golden crown.

While being held captive by the Hero Faction; her attire consisted of a yellow kimono, a golden obi, and wore a black pelt, with gold skulls and lines printed on it. The kimono features a white interior and it is open at her shoulders, giving view to her enormously large breasts. Her hair was held back by a traditional hair ornament, with six golden bira kanzashi and several red kanzashi.

In her real form, she has the appearance of a giant nine-tailed fox with golden fur. Issei describe this form to be at least ten meters in height, and possibly bigger than Fenrir.


Yasaka is shown to be very humble and polite, as well as a loving mother and a dedicated leader. However, she also has a teasing, slightly flirtatious side.


Not much is known about Yasaka, other than at some point before the arrival of Issei and the second-year students of Kuoh Academy, she was captured by the Hero Faction.
