Towa no Shirube (永遠の標)
Background
In the anime, Towa is a bird statue that Dark was to steal from the ruins of an old house that was damaged by a landslide. When Daisuke first finds her statue he calls her very valuable and from then on (when she was later released and took the form of a cute young girl) she became very loyal and compassionate towards Daisuke. Personality wise she is very optimistic, enjoys shopping and cooking, compassionate, caring and is somewhat of a romantic.
Unlike in the manga, she is also able to retain her human form during the day and only occupies her bird form when she is weak, flustered (whenever she gets kissed by Dark) or playing with With. She stays with the Niwa family as their house maid.
Towa (in human form, as the Niwa family's maid) dresses in the Gothic Lolita style.
