Amu Yunos

Calamity Demon Amu Yunos is one of the eight Demon Lords of Ishgria. She rules over the land of Zamburg. Amu Yunos is depicted as easy-going compared to other Demon Lords, as well as being extremely bored due to her long life, to the point that she desired death. She is implied to be the strongest of the demon lords because of her age, being able to cause a volcanic eruption with a wave of her hand.
