Pierce, Annette

アネット＝ピアス

In the Manga
Annette is an information broker and a former sweeper who appears to have some old connections with Sven. She runs the Cait-Sith Cafe, which serves as an occasional meeting place for Train and his companions. The cafe's name, Cait Sith, is a mythological reference. She is beaten up by Durham when he comes looking for Train for a duel and fails to find him around.
In the Anime
The situation is pretty much the same, except that Durham does not meet her in the anime.
