Urd is Belldandy's older 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.

Although her powers exceed those of her sisters, she was supposedly relegated to second class ranking due to her tendency to lie, said Belldandy early in the manga. Later, the real reason that she dropped the first class license examination was revealed to be because she was asked why she wanted to be a first class goddess. She only wanted power to protect her sisters, not power to protect all beings (as a first class goddess would do). Urd has extensive knowledge of potion lore. Urd recharges her energy by drinking sake and travels via television screens. She bears the emblem of the past. If allowed to wield her full first class power unsealed, Urd could possibly be the most powerful of the Goddesses on Earth. Her power is such that even just touching Peorth (a first class Goddess) caused bruising on the latter.

Urd fancies herself a Goddess of Love, although the mishaps of using her magical potions and her general lack of restraint tends to complicate, rather than stimulate, Keiichi and Belldandy's love life. She came 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 banished her from Heaven until further notice. That notice came after the Terrible Master Urd episode c. chapter 47, but by then she wanted to stay on Earth and everyone helped muck up things so she couldn't go back right away. She and Skuld have since done emergency duty on Yggdrasil in heaven at least twice since then, as of ch 162.

As she demonstrates in the manga, she can exercise immense control over her powers despite her second-class status. She was able to draw her personal sigil using first-class lightning magic on her first attempt, a task that required First Class Goddess Peorth numerous attempts to successfully complete.

Urd shares a common father with her younger sisters (Belldandy, Skuld), but has a different mother, the Demon Lord Hild. Because of this, Urd is half-Goddess and half-Demon, reflected in the half-white, half-black appearance of her Angel, World of Elegance. Perhaps due to her Demonic heritage, instantly puts Urd to sleep and she is unable to awaken until the music ceases.

Keiichi's friends (and his sister Megumi) are aware of Urd's existence and her relationship with Belldandy and residency at Keiichi's home; however, for the most part they are not aware of her "goddess" status.

For the longest time, she was unable to summon her angel since she was so scared when she first saw it and ordered it never to come out. This was caused by her self-doubt at being half-Goddess and half-Demon since she equated having pure white wings as the sign of being a true Goddess. She has since gotten over whatever self-doubt that was holding her back and can now once again call her angel at will, much to Skuld's chagrin (she had originally thought that Urd had no angel and wanted to top her eldest sister by being first).
