Urd

Urd is Belldandy's older half sister and is the second Goddess to appear to Keiichi. Urd ranks as Goddess second class, management category limited license, similar to her youngest sister Skuld. She is the Yggdrasil System Administrator and Manager. Though she is much more powerful than her sisters, she could not become a first class goddess because she only wanted power to protect her sisters, not power to protect all beings. Urd shares a common father with her younger sisters, but has a different mother, the Demon Lord Hild. Because of this, Urd is a hybrid of Goddess and Demon, reflected in the half-white, half-black appearance of her Angel, World of Elegance.

Urd fancies herself a Goddess of Love, so she comes to Earth to spur Keiichi onward with love potions and well-meaning, but deceitful advice, but as punishment for deserting her post and for using her powers on Earth without authorization, The Almighty banishes her from Heaven until further notice. After being allowed to go back, she decides to stay on Earth instead.
