Hild

Hild is the leader of Hell; her official title is Daimakaichō (大魔界長, literally translated as Great Demon World Leader). She is, to date, the most powerful demon in Niflheim, although she is currently rivalled by her daughter, the half-demon half-goddess Urd. Hild, at first impression, is a very cheerful and happy-go-lucky person. However, under that exterior, she is very manipulative, calculating and merciless. After she leaves to Niflheim after restoring Peorth's adult-form, she eventually returns in the form of a miniature of herself. Much like how Belldandy and Urd can split into many miniatures of themselves, Hild has the ability to leave a fraction of herself behind in the form of a little girl. She continues to wreak havoc in this way.
