Sigel

Japanese name:

シーグル

Sigel was originally an antique welcome mannequin with the form of a ten-year-old girl, with a "welcome" message recorded in an internal tape player. The property of an antique shop, Banpei fell in love with the mannequin on first sight, even going so far as to take her immobile form out on a date. The mannequin's voice player finally broke down and she was sent to the scrapyard, to be claimed by Whirlwind Garage owner Chihiro. Chihiro gave the mannequin, with a new digital voice player, to Skuld. After Skuld re-makes the mannequin into a sentient, walking robot, it demonstrates a reluctance to establish a relationship with Banpei, though she secretly does have a soft spot for him due to his devotion for her. This welcome robot was not named until much later by Belldandy.

Sigel shows a great deal of admiration and affection for Skuld, whom she addresses as "mistress", and she has also been seen showing respect for Belldandy. Sigel tries her best to keep demons away from the temple, although she lacks the impressive array of weapons that Banpei has. Her only weapons are skating wheels in the heels of her feet and detachable rocket punch hands (when asked about these, Skuld states that they are standard issue for robots).
