Zeit (ツァイト Tsuwaito?) is a mysterious wolf who aids Lloyd and his friends in the Zero/Ao no Kiseki duology. He reveals himself before the Ao finale, as the beast guardian for the "Mirage Treasure", namely KeA.
Zeit's canine appearance is a large azure wolf, with a white fur coat bordering around the sidelines of its paws, underbelly and capes. It also wears a brown collar on its neck, and gold hind-guards on the front of its paws and legs.
In its true form, Zeit's height grows ten times higher with its azure appearance becoming navy sapphire. The fur capes on the upper joints of its four legs and undercool sprout up like wings.
While Zeit look bigger, yet no different from an average wolf, it show capable leadership such as howling packs of its herd on its command. After moving into the Special Support Section building, it shows neutral obedience like an ordinary dog buy napping on the entrance's floor mat and heeding KeA's and Tio's needs when summoned.
