Presea

プレセア

Presea is the leading blacksmith in Cephiro, recognized there as a Pharle or "artisan." She is one of Clef's students and appears to have a crush on him. She assisted the Magic Knights by forging their legendary escudo swords.
In both the anime and manga series, she displays a somewhat sadistic side, devising ways to punish Mokona for making a mess in her study (including pulling his ears, hanging him upside-down while she dances around him dressed as a Native American, and forcing his ever-closed eyes wide open). Her trap accidentally captures the Magic Knights, so she considers whether to stretch their cheeks or boil them in a large pot, again wearing a feathered headdress and performing a war dance. In the anime series, she is killed by one of Ascot's beast summons. This death occurs only in the Anime, and created a rather large plot hole.
In the anime version of the second series, her twin sister, Sierra, poses as her to correct this plot hole. The only ones to realize that Sierra is not Presea are Clef, Mokona, and Alcyone, who recognizes Sierra's deception as stemming partly from her love for Clef. When Clef confronts Sierra about why she is posing as her sister, Sierra replies that it is to help the Knights with their mission and continue her sister's legacy, but doesn't reveal her own feelings for him.
Presea's favorite food is listed as V-tek, a kind of candy from Cephiro (though she enjoys the candy from Earth that Hikaru gave her almost as much).
