Ibuki

The ruler of Avidya Forest and long living mononoke: Ogre Lord Ibuki. Notably known for threatening death over those that enter her forest, Ibuki is rather territorial with her domain. Though she says such things, she isn't as violent as she lets on. Instead, she just wishes to protect her land from any harm, be it from mononoke or humans. Even with her territorial nature, Ibuki has managed to get a husband, Monjumaru that she's been with for over 200 years.

For the most part, Ibuki is, in reality, a kind individual. So long as she may permanently reside in her forest, she is happy. Lest anything causes harm to anything in Avidya Forest, Ibuki will then harm them. Otherwise, she has no problem with humans and mononoke. While she's with Monjumaru, the two are rather sappy with each other and a loving couple in general. After years with Monjumaru, the mutually agreed to make him undying. Ibuki gave half of her power as a mononoke to him, making him immortal and a half-mononoke. Ibuki has met many mononoke in her years, most notably Amagi. Luckily, he did not cause any harm and instead just voiced his disdain for her lifestyle.

In present time, Ibuki has helped Jirou Azuma get a grasp on Ragou's power implanted in him, and successfully trains him as much as she and Monjumaru could.
