Annin Character Facts

Annin is the guardian of the sacred Furnace of Eight Divisions, the border between life on Earth and the Other World. She is among one of the few beings working under King Yemma that does not appear to be an ogre, and instead looks to be somewhat human in physical form. Annin is immortal, and presumably ageless. 
Annin is the sole pyre keeper of the Furnace of Eight Divisions, having secured the position for over ten thousand years. She is indeed very ancient due to this fact, even in spite of her attractive and youthful appearance.
