Deacroft, Silphy

シルフィー＝デアクロフト

In the manga
Silphy is another member of the sweepers who form the Sweeper Alliance. Her specialty is body combat. She battles Deek Slasky, but he manages to deliver an attack that continually freezes her until she turns into a complete ice statue. However, while the ice is still spreading through her arm, Sven appears and fights Deek, damaging him so that his Chi is not strong enough to maintain the spell, saving Silphy.
In the anime
The same, except she does not battle Deek, as he doesn't appear, and she is attacked by Preta instead, whom Sven fights to save Silphy.
